A T T E N T I O N ! Signal Path Insert Points This TV-1000 audio console is equipped with insert patch points on the following modules: Submasters AUX master signals SUBMASTER signals Stereo Masters STEREO MASTER output signals Unless these points are jumpered (either internally via PCB-mounted jumpers OR looped through at each module’s DB-25 rear panel connector) audio signal will not pass. As shipped from the factory, PCB-mounted insert jumpers have already been installed. If you intend to use outboard signal loops at these points, you must remove the factory installed jumpers. See “Submaster Module Internal Programming” (Chapter 3) and “Master Module Internal Program– ming” (Chapter 4) in the TV-1000 Technical Manual for details. NOTE: While input modules also have insert points, these may simply be front panel bypassed by an “insert” switch at the top of each module.

WHEATSTONE AUDIO CONSOLES May 1998 AT T E N T I O N ! Dual Redundant Power Supplies If your Wheatstone audio console has been ordered and shipped with a failsafe power supply system, it uses TWO separate rackmount power supplies. Though either is capable of running the console on its own, in failsafe operation both units run in tandem: if one fails, the other takes over, assuring uninterrupted console operation. Dual failsafe supplies have their output trimmed to entirely different settings than stand-alone single units, and are MEANT to be run in tandem. If they are not, and you attempt to “save” one supply by powering it down and holding it in reserve until you run into an actual failure condition, you could shorten the life expectancy of the working unit. ! In order for the failsafe system to perform as designed, always have BOTH rackmount supplies powered up and connected to the console.

Your Wheatstone TV-1000 audio console is equipped with two "module extractor tools" which are mounted underneath the console armrest, to the far right (just in front of the operator’s mainframe headphone jack). Main module faceplates are held into the console mainframe by three fasteners: a lower rear panel screw (below the module’s I/O connectors, located at the rear of the console beneath the meterbridge assembly) and two faceplate mounting screws (top and bottom) located on the control surface of the console. The faceplate mounting screws, when removed, leave specially threaded holes that accept the two extractor tools. To remove a module faceplate from the mainframe: Remove the rear panel screw, then the front top and bottom mounting screws. Remove the extractor tools from underneath the armrest, and screw each tool into a module faceplate mounting hole. Use only four or five turns (do not over-insert; you may damage the threaded mainframe hole underneath). Using the extractor tools as handles, pull the module straight up out of the mainframe.

page 1 – 2 TV1 / May 98 Installation Console Placement TV-1000 consoles are HEAVY. A fully loaded 70 position main- frame can easily weigh 600 to 700 lbs. We recommend using at least six people to move and place the console. Console placement should avoid proximity to any electromagnetic fields, such as large power transformers, motors, and fluorescent lighting fixtures. The console may be mounted either on a custom constructed table surface or the optional factory leg support system. In either case, the console's handrest top surface would generally be located 29-30 inches from the floor. Do not connect the TV-1000 console to its power supply (and do not connect the power supply to the AC power line) until instructed to do so. Factory Leg Support System The optional factory leg system supports the console at sitdown height, and provides a hidden internal wiring chase that may be closed off with a rear concealment panel. The leg support system is pre- assembled at the factory, then broken down for shipment. Field assembly instructions are included in a separate document supplied with the legs. They are also reproduced in the Appendix of this Technical Manual (see page A-8). System Ground The first step is to ground the console. Note that as supplied from the factory, console rackmount power supply common, audio common, and the TV-1000 mainframe are connected together at the console, but are NOT connected to electrical ground and the chassis of the power supply. Safety requirements dictate that a positive connection from the console mainframe to electrical ground be made in the completed installation. Use one of the grounding lugs on the bottom of the mainframe to establish your system ground. The grounding lug terminal strip may be found at the rear of the console, along the bottom edge of the mainframe pan directly under the rightmost mainframe slots (to the extreme lower left if you are looking at the rear of the console). !

Tie the console ground lug terminal strip to the system earth ground. Tie every piece of equipment in the entire audio system to the console ground lug terminal strip. The system ground serves two important purposes: (1) It provides a zero signal reference point for the entire audio system; (2) It assures safety from electrical shock. There exist two terms that one encounters in a discussion of ground: (A) EARTH GROUND, which is usually a heavy copper rod driven into the soil adjacent to the building (around 6 feet down) or a connection to the copper water pipes leading into the building. Either is acceptable (unless, of course, the water pipe is made of plastic). (B) THE POWER COMPANY EARTH CONDUCTOR that enters the building at the power line breaker box; this conductor should be (and is often by code) tied to the above-mentioned earth ground at one point. This point is the SYSTEM EARTH GROUND. TIE THE CONSOLE GROUND LUG TERMINAL STRIP TO THE SYSTEM EARTH GROUND. TIE EVERY PIECE OF EQUIP- MENT IN THE ENTIRE AUDIO SYSTEM TO THE CONSOLE GROUND LUG TERMINAL STRIP. If the system earth ground point is inaccessible, tie the console ground terminal strip to the power company earth conductor at the main breaker box (see drawing "Typical Grounding Scheme" above).

page 1 – 4 TV1 / May 98 An “isolated AC ground” studio outlet (usually or- ange in color) can also be used to accomplish the required grounding. Each piece of equipment should be connected by its own ground wire (usually the round third pin on the AC cord). This means that every AC outlet must have a separate conductor run to the console ground lug terminal strip; the outlets cannot be daisy-chained as is normally encoun- tered in commercial and residential AC systems. Any equipment not supplied with 3-wire AC cables must have individual ground wires (16 gauge or larger) connected to their chassis grounds and then run to the console ground lug terminal strip. Further Grounding Details Check all equipment to be absolutely certain that each unit is power transformer isolated from the AC mains to prevent safety hazards. It is assumed that in each piece of audio equipment the audio ground and the chassis are tied together at some point. Any piece of equipment lacking a grounded chassis is likely to be prone to interference problems. Locate all unbalanced audio equipment in the same rack if possible, to minimize chassis ground potential differences. It may also be helpful to insulate each piece of unbalanced equipment from its mounting rails in the rack by means of nylon 10-32 screws and insulating washers between rails and faceplates. Once the system is properly grounded, proceed with the console power supply installation and connection (next section). Power Supplies For a complete discussion of TV-1000 power supplies, see the “TV-1000 Power Systems” chapter of this manual (page 9-1). For the purposes of the current chapter, you should properly rackmount the PSC-1000 (console), PSC-125 (Event Computer) and PSC-340 (rackmount smart select cage) power supplies and connect them to their associated equipment as described in the “Power Systems” chapter. (If failsafe versions have been ordered, you will be installing two units of each type.) Note the power supplies should be mounted in an equipment rack within fifteen feet of the console (but no closer than 3 feet). Avoid locating any high gain equipment (such as phono preamps, tape recorders, etc.) too near the rackmount supplies, to avoid magnetic interference into that equipment. If the optional Wheatstone FC-4 fan unit has been ordered, install and connect that to the PSC-1000 supply per the information given on pages 9-3 and 9-4. Once the supplies are rackmounted, they should be connected to their respective equipment using the supplied cables. Note that each cable’s 10-pin female connector has to be rotated until its locating pins match the male connectors on the equipment it powers. Do not force a connector on; it attaches easily when properly aligned. Connect the cables first to the rear of the their associated equipment, then to the rear of each rackmount power supply.

page 1 – 5 TV1 / May 98 Note each power supply is fitted with a 3-wire grounded AC cord that should be plugged into a "clean" AC power source. That is, an AC source that feeds only the control room audio gear. This source should be a separate feed from those powering lighting, air-conditioning, or any other non-audio machinery. The third pin ground wire of the AC source should be tied to the central system ground point. Note that while the AC power cord ground wire terminates at the power supply chassis, it does NOT connect to the TV-1000 console common; the console itself must be grounded separately. (See previous section, "System Ground".) Failsafe Dual Redundant Supply Wheatstone failsafe power supply systems use two separate rack- mount power supplies for each piece of powered equipment. Though either is capable of running a full load on its own, in failsafe operation both units run in tandem: if one fails, the other takes over, assuring uninterrupted operation. NOTE dual failsafe supplies have their outputs trimmed to entirely different settings than stand-alone single units, and are MEANT to be run in tandem. If they are not, and you attempt to “save” one supply by powering it down and holding it in reserve until you run into an actual failure condition, you could shorten the life expectancy of the working unit. In order for failsafe systems to perform as designed, always have BOTH rackmount supplies powered up and connected to their associ- ated equipment. The “TV-1000 Power Systems” chapter fully covers rackmount installation and connection of failsafe supplies. Energizing the Supplies (1) THE CONSOLE – Assuming the TV-1000 console mainframe is properly placed and grounded, and its PSC-1000 power supply correctly rackmounted and connected to the console’s power interface module rear panel, you may now energize the PSC-1000 rackmount power supply by plugging it into the AC mains and turning it on, using its front panel circuit breaker/switch. (If you are using a failsafe system, turn on BOTH supplies.) The five LEDs on the power supply front panel should light up to indicate the presence of their respective The power feed recom- mended in the text is often installed and referred to in studios as an “isolated AC ground” outlet. It is usually orange in color. ! TV1 / Aug 99

page 1 – 6 TV1 / May 98 voltages. The console's VU meters will illuminate; individual module switches will assume the settings they had when the console was last powered down (there is battery backup RAM built-in to the console to assure this). If this is your first power up, console settings will assume the factory default. (2) THE CONSOLE EVENT COMPUTER ACCESS PANEL – Again, assuming the event computer’s PSC-125 power supply is correctly rackmounted, connected to the rear panel connectors of the event computer access panel at the console, and the supply is connected to the AC main, turn on the supply (or supplies, if failsafe) using the front panel circuit breaker/switch. The supply’s two status LEDs should light up, indicating the presence of +12 and +5VDC, and the console’s event computer access panel should activate. (3) THE SMART SELECT CAGE – With the PSC-340 power supply correctly rackmounted and connected, energize the rackmount Smart Select Cage by plugging in the PSC-340 power supply to the AC mains. The Smart Cage should energize, with its switcher LEDs lighting to reflect the settings on the console’s associated overbridge preselector panels. (4) THE ROUTER CONTROL SYSTEM PC COMPUTER – With all the preceding equipment energized, boot the Wheatstone Router Control Computer at its separate keyboard. The monitor screen should light up, run through built-in diagnostics, and eventually display the Main Menu described in the Wheatstone Router Control System manual. It is best to energize the TV-1000 console, console event computer, and rackmount smart select cage prior to booting up the PC event computer; this way the computer will be able to immediately find the equipment it is connected to. If the PC is booted first, power-up will take much longer as the system keeps looking for equipment that is not yet activated. Once you have verified proper power-up, turn off the rackmount power Once you have verified proper power-up, turn off the rackmount power Once you have verified proper power-up, turn off the rackmount power Once you have verified proper power-up, turn off the rackmount power Once you have verified proper power-up, turn off the rackmount power supplies to de-energize their associated equipment.

Audio and Control Wiring All audio and control I/O connections to the TV-1000 console are made through multipin connectors (DB-25 and DB-9 type) located at the rear of the console. The Insulation Displacement Connector System The I/O wiring interface system is based on insulation displacement technology. A special AMP wiring tool is included with each console; it is auto-indexing, and allows individual wire connections to be positively made with a single squeeze of the tool's trigger. The trigger action is ratchet controlled, and will not release until a full connection For a more complete discus- sion of Event Computer and Smart Cage start-up proce- dures see page 10 of “The Wheatstone Router Control System” technical manual.

The tool, multipin connectors (with gold plated pins) and latching hoods are supplied with each console. is made. Once released, the multipin connector held in the tool's jaw automatically indexes to the next connector pin. The technology is such that no stripping, soldering or tinning of wire ends is required; all that is needed is for the wires destined for the connector be snub cut and laid out in order (although tubing should be used on bare drain wires). An empty DB-25 or DB-9 connector is inserted into the tool, indexed to the first pin, and the wires are inserted one by one into the jaw and the trigger squeezed. In this way a single multipin connector can be completely wired up in a minute or two. In the event of a wiring error, connector pins may easily be removed from the shell with the wire still attached, and inserted into the correct position. Observe the side of the connector, with the metal part down. You will see a row of "Vees"—simply press the top of the vee together with a scribe or other sharp instrument; this will unlock the pin from the shell, and it can be removed and inserted into the correct position. Spread the vee apart to lock the pin in the new position. It should never be necessary to discard a connector due to a wiring error. Note that mating right angle hoods for each connector are also supplied with the console. These have locking tabs that hold the connectors securely to the bottom of the console mainframe. Connection Procedures As supplied from the factory, the console requires no logic connections to function. Therefore an orderly installation begins with the audio wiring. Note this manual is organized by module type (inputs, submasters, masters, monitor modules, etc.); each chapter contains detailed wiring instructions for its module type. Proceed through the manual, chapter by chapter, until all modules have been wired to suit your particular installa- tion requirements. Once proper audio operation is verified, go back to each individual chapter and proceed with control wiring.

page 1 – 8 TV1 / May 98 Insert Points Certain module signals have built-in insert patch points in their signal chains to allow outboard audio processing. These include SUBMASTERS (with both submaster and auxiliary master insert points) and STEREO MASTERS (stereo master output signals). Normally these points are internally bridged at the factory (via PCB- mounted jumpers) prior to shipment. If you intend to use outboard signal loops at these points, you must remove the factory installed jumpers. See pages 3-6, 3-7 (submasters) and 4-6 (stereo masters) for details. NOTE: While input modules also have insert points, these may simply be front panel bypassed by the “insert” switch at the top of each module. Unbalanced Connections INPUTS — Wire to the console with typical shielded two conductor cable (like Belden 9451), just as if you were connecting a balanced source. At the unbalanced source machine’s output, connect the black wire (LOW) to the shield. If the machine has a -10 dBu output, don’t hesitate to turn module input gain as high as is needed. OUTPUTS — TV-1000 consoles use a balanced output circuit which behaves exactly like the secondary of a high-quality transformer, with no center tap—this output is both balanced and floating. Either the HIGH or LOW side of the output should be strapped to ground, with the output taken from the other side. (Normally you’d strap LOW to ground, and take HIGH to feed your unbalanced equipment.)

TV1 / May 98 S T E R E O M I C / L I N E I N P U T Stereo Mic/Line Inputs General MLS-1000 input modules accept and output stereo signals. Each module can select one of four stereo source signals: two are mic level and two are line level. Each input channel consists of three separate panels mounted in a single mainframe position: a) the main module itself (far right), b) a fader panel directly in line with and below the main module (physically separated by the console’s alpha- numeric source display strip), and c) an (optional) 8-bank preselector switching panel located directly above each channel in the meterbridge overbank section. Input channel audio I/O (input/output) connections are made via two DB-25 multi-pin connectors (“A” upper; “B” lower) located on the back rear panel of each main module. Input channel logic and control signals are made through a DB-9 “Control” connector directly below the two DB-25 audio connectors (see page 2-11). An additional DB-9 connector, “mute follow”, is mounted on each rear panel; it is used to allow preselector sources to activate the console’s four mute/tally signals. Note console preselector panel switches do not control audio directly. Instead, they send control pulses to separate rackmounted switching cages (“Smart Select®” cages). Actual audio source signals are wired directly to the rackmounted Smart Select® cages (via rear chassis-mounted DB-25 connector pairs); the cages then feed selected source signals back to the main input modules. The signal flow diagram on page 8 of the Technical Drawings is helpful in clarifying the information presented in this chapter. You are encouraged to refer to it in conjunction with the text that follows.

TV1 / May 98 S T E R E O M I C / L I N E I N P U T Main Module Input section The upper section of the MLS input module selects between two stereo microphone and two stereo line inputs. The microphone section provides a variable input gain control, switched left and right -20dB pad circuits, and switchable +48V phantom power (labeled “V+”). The electronically balanced line input section has a center detent input gain control (with PCB-mounted calibration trimpots for fine adjustment). Left and right phase reverse switches affect both mic and line inputs. A patch point INS switch (for both mic and line) allows insertion of any pre-patched external processing gear (insert points are electronically balanced in and out). AUX Section This section taps eight summed (L+R) post-EQ auxiliary send signals from the main input channel and routes them to the console’s send ACN busses. There is a pre/post selector switch and an ON switch for each aux circuit. NOTE aux circuits may also be programmed to operate as left/right stereo pairs via PCB-mounted programming dipswitches (see page 2-15). Also, while aux pre/post switches nor- mally switch before or after both the channel fader AND channel On switch, special PCB-mounted slide switches (four per module) permit dual AUX pairs to follow main channel ON/OFF even when switched to “pre” (page 2-15). BAL/MIX Control – MODE Switch The center-detent BAL/MIX rotary control operates in conjunction with the module’s MODE switch. Here are the possible settings and functions: Stereo Mode (ST) – Default setting (MODE switch cap illumi- nates); the rotary control functions as a regular L/R stereo balance pot. Mono Mode (MN) – Rotary control functions as a pan pot (a L+R summed signal is panned L/R within the module’s stereo field). Right Mode (RT) – Rotary control pans the right channel signal L/R within the module’s stereo field. Left Mode (LT) – Rotary control pans the module’s left channel signal L/R within the module’s stereo field. Mix Mode (MIX) – The module is put into mono sum mode; the rotary control then determines the left-right makeup of the mono sum signal, which remains dead center within the stereo field (i.e., fully counterclockwise: left signal only; center detent: mono sum of equal strength left and right signals; fully clockwise: right signal only; intermediate settings: varying L/R signal strength mix ratios. Useful for setting the balance between field or studio voiceovers and field-recorded actuality audio. 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 A U X 1 A U X 2 A U X 3 A U X 4 A U X 5 A U X 6 A U X 7 A U X 8 P R E O N O N O N O N O N O N O N O N C 1 2 3 4 1 2 3 4 5 6 7 8 P K EQ SOLO CUE S U B M A S T E R S P R E P R E P R E P R E P R E P R E P R E RT MN ST L BA P R E P R E P R E P R E M O D E M S M IX L T R T S T — LT M S T R S L O W - + 3 0 3 11 11 dB dB Hz 900 600 250 60 450 M I D 3 0 3 11 11 dB Hz 7K 5K 2K .5K 8K 400 3.5K H I 3 0 3 11 11 15K 10K 4K 1K 16K 800 7K 16 16 - dB+ 16 16 - dB+ 16 16 9K 35 5K 25 6 2 0 8 1 5 1 70 26K .7K 2 .5K 3 LPF HPF Hz H I/LO IX M 1K 40 M N MLS 1 2 1 2 Ø L R dB 7 60 5 5 5 7 5 4 0 V+ L R MIC LINE SSS STTTTEEEERRRREEEEO O O O INS P A D 9 dB 1 6 3 6 2 12 - 9 15 M I C L I N E +15 TV1 / Oct 98

TV1 / May 98 S T E R E O M I C / L I N E I N P U T Middle/Side Mode (M/S) — Intended for live or recorded signals that utilize two monophonic microphones: one (feeding the module’s left channel) a cardioid mic directed along the main axis of the sound to be recorded; the other a figure-eight mic (feeding the module’s right channel) aligned at right angles to the cardioid pickup . When these are fed through the MLS-1000 module functioning in M/S mode, the rotary control will act as follows: when turned all the way to the left (counterclockwise) the LT (cardioid) signal is sent to both left and right module channels and a central “middle” effect results; when turned right (clockwise) the RT (figure-eight) signal goes to left and “–RT” (out-of-phase RT) goes to right, resulting in a “side” effect. In center position the rotary control sends a “LT plus RT” signal to the module’s left channel and a “LT minus RT” signal to the module’s right chan- nel. Intermediate settings produce combinations of the above.* Bus Assign Each input module may have its output assigned to any combination of the console’s four stereo MASTERS and/or eight stereo SUBMASTERS. Equalization Section A four-band stereo EQ/filter section is included, employing 3 sweep frequency peaking sections (each ±16dB with reciprocal curves) plus sweep frequency (-12dB/octave slope) low pass (2.7KHz-26KHz) and high pass (12Hz to 260Hz) filters. Note the three-band EQ and HI/ LO pass filter sections may be switched in and out separately. Peak LED A peak reading LED indicator lights to indicate overload conditions within the channel circuitry (the indicator monitors both pre and post fader points in the signal chain). Cue and Solo Both pre-fader CUE and post-fader/post-channel on SOLO func- tions are provided. These switches tap the module’s PFL and AFL signals and route them to the console’s stereo SOLO/CUE monitor bus, where they may be used to feed operator headphones, control room monitors, dedicated speakers, etc. (SOLO/CUE is mastered at the console’s control room monitor module; see Chapter 5.) Note CUE may be programmed to automatically drop out whenever the module’s ON switch (see fader panel section) is activated (see page 2-13, “Cue Dropout”). Direct Out Each input module has an electronically balanced direct output. It is post fader, post channel ON. *TECHNOTE: Use of an X-Y scope (Lissajous display), phase coincidence metering, and accurate monitoring is highly recommended to assure both pleasant and mono-compatible output when using the M/S mode feature. 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 A U X 1 A U X 2 A U X 3 A U X 4 A U X 5 A U X 6 A U X 7 A U X 8 P R E O N O N O N O N O N O N O N O N C 1 2 3 4 1 2 3 4 5 6 7 8 P K EQ SOLO CUE S U B M A S T E R S P R E P R E P R E P R E P R E P R E P R E RT MN ST L BA P R E P R E P R E P R E M O D E M S M IX L T R T S T — LT M S T R S L O W - + 3 0 3 11 11 dB dB Hz 900 600 250 60 450 M I D 3 0 3 11 11 dB Hz 7K 5K 2K .5K 8K 400 3.5K H I 3 0 3 11 11 15K 10K 4K 1K 16K 800 7K 16 16 - dB+ 16 16 - dB+ 16 16 9K 35 5K 25 6 2 0 8 1 5 1 70 26K .7K 2 .5K 3 LPF HPF Hz H I/LO IX M 1K 40 M N MLS 1 2 1 2 Ø L R dB 7 60 5 5 5 7 5 4 0 V+ L R MIC LINE SSS STTTTEEEERRRREEEEO O O O INS P A D 9 dB 1 6 3 6 2 12 - 9 15 M I C L I N E +15

TV1 / May 98 Preselector Panel TV-1000 input modules may be supplied with optional overbridge preselector panels. These consist of an eight-bank switch array that determines the source signal being fed to the main module’s Line 1 input. As stated before, preselector panels do not control audio directly; they send control pulses to switcher cards mounted in a separate rackmount Smart Select® cage. The cage card then returns the appropriate signal to the module. See pages 8-5 thru 8-8 for smart cage wiring details. TV-1000 consoles may also be ordered with overbridge preselector panels that interface directly with a station switcher rather than a Smart Select® cage. The operation principle remains the same; the preselector switch sends a control pulse to the station switcher, which then selects and returns the appropriate audio signal to the module. Note preselector panel switches can be programmed (through the Wheat- stone RCC Event Computer’s separate keyboard and monitor) to display 4- character alpha-numeric source codes that signify which source has been selected. These codes are displayed on the console’s source display strip, located just above the console’s fader panels. Note the source display will follow the main module’s input selector switches (i.e., Mic 1, Mic 2, Line 1, Line 2); however, when Line 1 is selected at the module, the source display will show the currently selected preselector panel’s source code. Smart Select® cage and Event Computer operation is covered in a separate technical manual (“The Wheatstone Router Control Sytstem”). Input Fader Panel Each input module has an associated fader panel located directly below it. Starting from the bottom, these panels are configured as follows: Fader A 3000 Series Penny & Giles long-throw (104mm) stereo fader. Plug-in for easy servicing. Mute Groups Each input channel may be assigned to any or all of four Mute Control Groups. These groups (A thru D) can then be muted by the press of a single master mute button. (In other words, whenever the master switch for a mute group is activated, any module assigned to that group will have its output muted.) A “mute” LED indicator lights whenever a module has been muted. (The four mute master switches are located in the fader section of the board, directly underneath the power interface module in the center of the console.)

TV1 / May 98 FADER PANEL Mix Minus Feeds a summed version of the module’s signal to the console’s mix-minus system. Any module turned ON automatically feeds a signal to all eight mix-minus busses. Creation of a feed for IFB or remote use is done by simply pressing one or more of the eight mix- minus switches on the chosen input module’s fader panel, which removes that module's feed from the selected busses. Illuminated mix- minus switches thus show the deselected status directly at the input source. Note the mix-minus signal may be programmed (by an internal PCB-mounted slide switch) to be pre or post fader; a programming jumper permits the mix-minus feed to follow channel ON/OFF. See page 2-14, “Mix Minus” for details. Ready LED Used for line inputs; this tally LED is powered by an external source machine to indicate when it is cued-up and ready for play. Channel ON This momentary action lighted pushbutton switch turns the input channel on and off. It may also be programmed to activate tallies (4), monitor mutes (4) and timer restart. A DB-9 control port lets the switch control (or be controlled by) external devices. See this chapter, “Input Module External Control Ports” and “Input Module Logic Program- ming” for a complete discussion. Bus Minus® Foldback In addition to the eight bus mix-minus system previously described, each input module can also produce its own independent mix-minus feed, called Bus Minus®. This is accomplished by pressing the Bus- Minus IN switch, which places a summed version of the module’s signal onto a special dedicated ACN mix bus, where it becomes available to other modules for use in their own Bus-Minus functions. A rotary level control (FB or foldback) outputs the dedicated ACN bus mix—with or without the module’s own signal, depending on the setting of the +/- switch (see immediately following)—to a connector on the module’s rear panel. The “+/-” switch, when pressed, illumi- nates and removes the module’s signal only from its own bus-minus output—the signal feed to the ACN mix bus (and other modules) remains unaffected. A TB switch (programmable to feed pre or post FB level control) sends console talkback audio to the module’s bus-minus output, which may be monitored at any time by a SOLO switch.

TV1 / May 98 Metering Each individual input channel has its own 7-segment mono sum LED VU ladder built in to that channel’s fader panel. This LED VU may be internally programmed to monitor pre or post fader. It is always, however, pre channel ON/OFF, allowing it to function as a signal present indicator. The VU ladder is calibrated via a PCB-mounted trimpot on the fader panel’s main printed circuit board (“CR1” – see “FPI-1000” load sheet on page 49 of the Technical Drawings, center left). Note a single PEAK LED indicator at the bottom of the main module faceplate also warns of overload transients (it monitors both pre and post fader). Input channels may also be metered at the console’s stereo SOLO VU meter pair in the console overbridge, just above the VU/Oscillator module. The SOLO meters may be driven pre or post fader, depending on whether the module’s CUE (PFL) or SOLO (AFL) switches are pressed. S T E R E O M I C / L I N E I N P U T

S T E R E O M I C / L I N E I N P U T Input Module External Control Ports The MLS-1000 input module may be turned on and off from a remote location by control wiring to the main module’s rear panel DB-9 “CONTROL” connector (bottom of rear panel): Remote On Provide a momentary closure between connector pins 6 and 7. This will latch the module ON. (User-supplied momentary contact switch required.) Remote Off Provide a momentary closure between pins 6 and 9. This will latch the module OFF. (User-supplied momentary contact switch required.) Ready LED The module’s fader panel has a green ready LED next to the channel ON switch. This LED can be powered by an external source machine to indicate when that machine is cued up and ready for play. The LED hookup pins are 8 (+) and 5 (–) [5VDC nominal]. The remaining control functions are input specific; that is, pro- gramming jumpers on the module’s switch PCB (MLSW-1000) assign them to Mic 1 and/or Mic 2, OR Line 1 and/or Line 2. Note the jumpers must follow the “Microphone versus Line Functions” PCB-mounted slide switch settings explained below (see also Signal Flow Diagram on page 8 of the Technical Drawings, lower left). If MIC functions have been programmed via the slide switches, then jumpers for M1 and/or M2 must be installed—NOT jumpers for L1/L2. Naturally, the reverse is also true. Generally speaking, input port control jumpers (zero ohm resis- tors) are already installed at the factory as required by client specifications, However, should you wish to install your own, see jumpers J5 thru J8, Technical Drawings “MLS-1000” switch card load sheet (page 22, center right). Input ports are enabled as follows: Mic 1: J8, Mic 2: J7, Line 1: J6, Line 2: J5. Programming for MIC or LINE is accomplished by a pair of PCB- mounted slide switches located at the top of the module’s switch PCB (SW33 & SW34). See Technical Drawings “MLSW-1000” load sheet (page 22, right). When viewed from the solder side of the board (as you would see it when examining an assembled module) these switches are accessed through a cutout in the PCB labeled “<-mics:lines->. When both slide switches are to the left, microphone functions (COUGH, TB TO CR) are active; when switches to the right, line functions (machine START and STOP) are active.

TV1 / May 98 CONTROL (DB-9) MACHINE COMM / GND START / TB TO CR STOP / COUGH EFS ON/OFF / ON TALLY READY– REMOTE OFF READY+ REMOTE ON ON/OFF COMMON / +5V S T E R E O M I C / L I N E I N P U T On Tally (Mic Function) This opto-isolated control function provides a continuous closure between CONTROL DB-9 pin 4 (ON TALLY) and pin 1 (GND) whenever the module’s channel ON switch is pressed. This closure can be used to control an externally powered tally light that requires a continuous closure to function. Or an external tally light (i.e., LED) can be powered from the input module by connecting the external LED to CONTROL DB-9 pin 6 (+5V) and pin 4 (ON TALLY). In either case, the current is not to exceed 50 milliamps. EFS On/Off (Line Function) This control function is designed to run European type source machines (as opposed to the American MACHINE START/STOP functions called out below). When the module is on, a constant closure occurs between CONTROL DB-9 pins 4 (EFS ON/OFF) and 1 (MACHINE COMMON). The MLS-1000 input module can also control remote devices by control wiring to the main module’s rear panel DB-9 “CONTROL” connector: Machine Start (Line Function) The remote source machine’s external on pins are wired to the console input module’s DB-9 CONTROL connector pins 2 (START) and 1 (MACHINE COMMON). Whenever the module’s channel ON switch is activated, the remote machine will start playing. Machine Stop (Line Function) The remote source machine’s external off pins are wired to the console input module’s DB-9 CONTROL connector pins 3 (STOP) and 1 (MACHINE COMMON). Whenever the module’s channel ON switch is deactivated, the remote machine will stop playing. Cough (Mic Function) A closure between CONTROL DB-9 connector pins 3 (COUGH) and 1 (GND) will turn the module off. Note this is a non-latching mode; the module will turn on again as soon as the closure stops (i.e., the user- supplied external COUGH switch is released). TB to CR (Mic Function) A closure between CONTROL DB-9 connector pins 2 (TB TO CR) and 1 (GND) does two things: a) the module’s PFL signal is placed on the console’s CUE bus (where it may be heard by the console operator) and b) the module’s COUGH function is simultaneously activated, to prevent the TB signal from accidentally going out over other assigned busses. This non-latching condition continues until the user-supplied external TB switch is released. TV1 / Oct 98

TV1 / May 98 S T E R E O M I C / L I N E I N P U T Input Module Logic Programming Mute/Tally The console has four separate MUTE control lines; each input module may be programmed to activate any of these via its channel ON switch. The MUTE control lines are used to shut off control room and studio monitor speakers whenever the microphone for that particular location is activated. The same MUTE control lines can also activate TALLY ports at the console’s control room monitor (CRM-1000) and studio monitor (STM- 1000) modules (see pages 5-6 and 6-5). Input module programming is accomplished by PCB-mounted dipswitches located on the main module PCB. Note each of the channel’s inputs [M1/2, L1/2] may be programmed separately. See Technical Drawings “MLS-1000” load sheet (page 16, lower right) and schematic (page 14, C-3). The input mute programming dipswitches are: Mic 1 – Dipswitch “SW24” Mic 2 – Dipswitch “SW25” Line 1 – Dipswitch “SW27” Line 2 – Dipswitch “SW28” NOTE on those input modules with an associated preselector panel, each preselector input can also be programmed to mute separately. The eight associated preselector panel dipswitches are “SW1” through “SW8”. See Technical Drawings “SB-1000” load sheet (page 145, center) and schematic (page 144, B-3). Mute logic control connections between individual input modules and their associated overbridge preselector panels are made via two DB-9 connectors at each input channel’s mainframe location. One is on the main module’s rear panel (“MUTE FOLLOW” Upper DB-9); the other is mount- ed directly behind each module’s preselector panel, on the rear of the console’s upper meterbridge. The two connectors are wired together, pin- for-pin, by an external multi-conductor cable. GROUP MUTES MUTE FOLLOW (PCB slide switch “SW26”) – Mute/Tally functions are normally programmed to follow the module’s channel ON switch. However, this PCB slide switch allows the mute/tally functions to follow the console’s four Mute Masters (A thru D, see page 8-12). Thus, when “SW26” is reprogrammed to the right (“GR mutes mute follow”) whenever an input module is muted via the group mute masters, its programmed mute/tally functions are automatically deactivated. See Technical Drawings “MLS-1000” load sheet (page 16, lower right) and schematic (page 14, C-3). Cue Dropout Input modules may be programmed to automatically drop out of Cue mode whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW22”. See Technical Drawings “MLS-1000” load sheet (page 16, lower right) and schematic (page 14, A-5). TV1 / Oct 98

TV1 / May 98 S T E R E O M I C / L I N E I N P U T Timer Restart Input modules may be programmed to automatically reset the console’s digital timer to zero and start it counting up whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW23”. See Technical Drawings “MLS-1000” load sheet (page 16, lower right) and sche- matic (page 14, C-1). Mix Minus The input module’s summed mix-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW18”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, lower left) and schematic (page 46, C-5). The default setting is “post”. The input module’s summed mix-minus assign signal may also be programmed to follow the channel ON switch via a programming jumper (“J1”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings “FPI-1000” load sheet (page 49, left center) and schematic (page 46, dead center). Bus Minus® The input module’s summed bus-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW19”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, lower left) and schematic (page 46, C-5). The default setting is “post”. The input module’s summed bus-minus assign signal may also be programmed to follow the channel ON switch via a programming jumper (“J2”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings “FPI-1000” load sheet (page 49, left center) and schematic (page 46, C-5). The talkback feed to the module’s bus-minus output may be programmed to be pre or post the foldback (FB) level control via a PCB-mounted slide switch (“SW20”) on the module’s fader panel main PCB. See Technical Drawings “FPI-1000” load sheet (page 49, lower right) and schematic (page 46, D-3). The default setting is “post”. Sum LED VU ladder The input module’s mono sum LED VU meter signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW17”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, extreme left) and schematic (page 46, B-7). The default setting is “pre”, which allows the meter to act as a “signal present” indicator.

TV1 / May 98 S T E R E O M I C / L I N E I N P U T AUX Sends The TV-1000 console aux SEND busses are normally configured as eight mono ACNs. However, they may be reprogrammed as left/ right pairs if desired. This is accomplished by PCB-mounted slide switches on the module’s main PCB (SW 14-21). See Technical Drawings “MLS-1000” load sheet (page 16, left center) and schematic (page 12, A-6 thru D-6). The programming switches are: Aux send 1 sum/left: SW14 Aux send 2 sum/right: SW 15 Aux send 3 sum/left: SW16 Aux send 4 sum/right: SW 17 Aux send 5 sum/left: SW18 Aux send 6 sum/right: SW 19 Aux send 7 sum/left: SW 20 Aux send 8 sum/right: SW 21 Note the above switches are reached through access cutouts in the module’s upper switchcard PCB. Aux send pairs may also be programmed to follow the module’s channel ON switch regardless of their individual front panel pre/post fader switch settings (this is the default setting). This is accomplished by PCB-mounted slide switches (SW 36-39) on the module’s switchcard PCB. See Technical Drawings “MLSW-1000” load sheet (page 22, right center) and schematic (page 18, A-4 thru D-4). The programming switches are: Aux send 1/2 pre on/off follow: SW39 Aux send 3/4 pre on/off follow: SW38 Aux send 5/6 pre on/off follow: SW37 Aux send 7/8 pre on/off follow: SW36 Mute Link The TV-1000 console mute link system is designed to activate mute/tally functions ONLY when a live microphone signal is present on-the-air (i.e., live at the console’s Stereo 1 master output). Individual input channels can be programmed to be part of the mute link signal chain via PCB-mounted slide switch “SW40”. The default setting is mute link DEACTIVATED. See Technical Drawings “MLSW-1000” load sheet (page 22, right center) and schematic (page 20, C-6). Note this slide switch is reached through a cutout in the switchcard PCB. Each input module also has a “machine link defeat” PCB-mounted slide switch (“SW42”), which allows machine control port micro- phone functions (i.e., machine start/TB to CR and machine stop/ COUGH) to be part of the mute link system chain. The default setting is machine link DEACTIVATED. See Technical Drawings “MLSW- 1000” load sheet (page 22, right center) and schematic (page 18, C-3). Note this slide switch is reached through a cutout in the switchcard PCB. TV1 / Oct 98

TV1 / May 98 M U T E F O L L O W A B I O I O CONTROL The module’s two DB-25 connectors (A & B) handle audio input/output signals. S T E R E O M I C / L I N E I N P U T Event Computer Start/Stop/Timer Enable When the TV-1000 console’s event computer takes a snapshot of switch settings on an input module, the channel ON switch state is included in the event storage. When the event is called up at a future time, the module may be turned ON or OFF depending on the snapshot and the current state of the module. If the module is programmed to fire an external source machine (via machine start/stop functions, see page 2-12) a PCB- mounted slide switch on the module’s switchcard (“SW41” on PCB MLSW-1000) gives you a choice of having the machine functions (AND the timer restart function) enabled or defeated for the event call-up. See Technical Drawings “MLSW-1000” load sheet (page 22, right center) and schematic (page 18, B-2). Note this slide switch is reached through a cutout on the solder side of the PCB. Mute Follow Connector The module’s MUTE FOLLOW DB-9 connector, located at the top of the rear panel, is used to transmit muting and tally control signals between the module proper and it’s optional preselector panel in the console’s overbridge. It is wired pin-for-pin to a matching connector mounted behind each preselector, on the rear face of the console meterbridge. Actual preselector mute/tally programming is done through PCB- mounted dipswitches (eight; one for each source) on each preselector panel switchcard. See Technical Drawings, “SB-1000 Smart Button” schematic (page 144) and load sheet (page 145). Input Module Audio Wiring All audio wiring for the stereo mic/line input module is via two DB-25 connectors mounted on the module’s rear panel. Audio signals include mic and line inputs (upper connector “A”) and insert point wiring, direct out, and bus minus out (lower connector “B”). See drawing on next page for detailed pinouts. Parts Lists MLS-1000 stereo mic/line input module parts lists may be found in Chapter 10. See contents on page 2-2 for specific list locations. Printed Circuit Board Load Sheets Load sheet drawings, showing all part locations, are in the Technical Drawings booklet (see contents on page 2-2 for specific drawing loca- tions).

page 2 – 18 TV1 / Oct 98 Mono Mic/Line Inputs General MI-1000 input modules accept and output mono signals. Each module can select one of four mono source signals: two are mic level and two are line level. Each input channel consists of three separate panels mounted in a single mainframe position: a) the main module itself (far right), b) a fader panel directly in line with and below the main module (physically separated by the console’s alpha- numeric source display strip), and c) an (optional) 8-bank preselector switching panel located directly above each channel in the meterbridge overbank section. Input channel audio connections are made via a DB-25 multi- pin connector (“A” upper) located on the back rear panel of each main module. Input channel logic and control signals are made through three DB-9 connectors (“MUTE FOLLOW”, “MIC LOGIC”, and “MACHINE CTRL”) also mounted on the same rear panel. Note console preselector panel switches do not control audio directly. Instead, they send control pulses to separate rackmounted switching cages (“Smart Select®” cages). Actual audio source signals are wired directly to the rackmounted Smart Select® cages (via rear DB-25 connector pairs); the cages then feed selected source signals back to the main input modules. The signal flow diagram on page 22A of the Technical Drawings is helpful in clarifying the information presented in this chapter. You are encouraged to refer to it in conjunction with the text that follows.

page 2 – 19 TV1 / Oct 98 Main Module Input section The upper section of this input module selects between two mono microphone and two mono line inputs. The microphone section pro- vides a variable gain control, switched Mic 1 and Mic 2 -20dB pad circuits, and switchable +48V phantom power (labeled “V+”). The electronically balanced line input section has a center detent input gain control (with PCB-mounted calibration trimpots for fine adjustment). The phase reverse switch affects both mic and line inputs. A patch point INS switch (for both mic and line) allows insertion of any pre-patched external processing gear (insert points are electronically balanced in and out). AUX Section This section taps eight post-EQ auxiliary send signals from the main input channel and routes them to the console’s send ACN busses. There is a pre/post selector switch and an ON switch for each aux circuit. While aux pre/post switches normally switch before or after both the channel fader AND channel On switch, special PCB-mounted slide switches (four per module) permit dual AUX pairs to follow main channel ON/OFF even when switched to “pre” (page 2-27). PAN Control This center-detent rotary control pans the module’s mono signal left and right within assigned stereo submasters and masters signals. Bus Assign Each input module may have its output assigned to any combination of the console’s four stereo MASTERS and/or eight stereo SUBMASTERS. Equalization Section A four-band EQ/filter section is included, employing 3 sweep frequency peaking sections (each ±16dB with reciprocal curves) plus sweep frequency (-12dB/octave slope) low pass (2.7KHz-26KHz) and high pass (12Hz to 260Hz) filters. Note the three-band EQ and HI/LO pass filter sections may be switched in and out separately. Peak LED A peak reading LED indicator lights to indicate overload conditions within the channel circuitry (the indicator monitors both pre and post fader points in the signal chain). 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 A U X 1 A U X 2 A U X 3 A U X 4 A U X 5 A U X 6 A U X 7 A U X 8 P R E O N O N O N O N O N O N O N O N LINE 1 2 INSERT 1 2 1 2 3 4 1 2 3 4 5 6 7 8 EQ SOLO CUE P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E C LT RT M S T R S S U B M A S T E R S P A N 1K L O W - + 3 0 3 11 11 dB dB Hz 900 600 250 60 450 M I D 3 0 3 11 11 dB Hz 7K 5K 2K 500 8K 400 3.5K H I 16 16 - dB+ 16 16 LPF HPF 3 0 3 11 11 15K 10K 4K 1K 16K 800 7K - dB+ 16 16 P K 9K 35 5K 25 6 2 0 8 1 5 1 70 26K .7K 2 .5K 3 Hz H I/LO 40 PAD 7 7 60 5 4 dB 5 0 5 5 M I C MI MIC 1 2 Ø V+ L I N E 9 dB 1 6 3 6 2 12 - 9 15 +15

page 2 – 20 TV1 / Oct 98 Cue and Solo Both pre-fader CUE and post-fader/post channel on SOLO switches are provided. These switches tap the module’s PFL and AFL signals and route them to the console’s stereo SOLO/CUE monitor bus, where they may be used to feed operator headphones, control room monitors, dedicated speakers, etc. (SOLO/CUE is mastered at the console’s control room monitor module; see Chapter 5.) Note CUE may be programmed to automatically drop out whenever the module’s ON switch (see fader panel section) is activated (see page 2-25, “Cue Dropout”). Direct Out Each input module has an electronically balanced direct output. It is post fader, post channel ON. Preselector Panel TV-1000 input modules may be supplied with optional overbridge preselector panels. These consist of an eight-bank switch array that determines the source signal being fed to the main module’s Line 1 input. As stated before, preselector panels do not control audio directly; they send control pulses to switcher cards mounted in a separate rackmount Smart Select® cage. The cage card then returns the appropriate signal to the module. See pages 8-5 thru 8-8 for smart cage wiring details. TV-1000 consoles may also be ordered with overbridge preselector panels that interface directly with a station switcher rather than a Smart Select® cage. The operation principle remains the same; the preselector switch sends a control pulse to the station switcher, which then selects and returns the appropriate audio signal to the module. Note preselector panel switches can be programmed (through the Wheatstone RCC Event Computer’s separate keyboard and monitor) to display 4-character alpha-numeric source codes that signify which source has been selected. These codes are displayed on the console’s source display strip, located just above the console’s fader panels. Note the source display will follow the main module’s input selector switches (i.e., Mic 1, Mic 2, Line 1, Line 2); however, when Line 1 is selected at the module, the source display will show the currently selected preselector panel’s source code. Smart Select® cage and Event Computer operation is covered in a separate technical manual (“The Wheatstone Router Control Sytstem”).

page 2 – 21 TV1 / Oct 98 Input Fader Panel Each input module has an associated fader panel located directly below it. Starting from the bottom, these panels are configured as follows: Fader A 3000 Series Penny & Giles long-throw (104mm) fader. Plug-in for easy servicing. Mute Groups Each input channel may be assigned to any or all of four Mute Control Groups. These groups (A thru D) can then be muted by the press of a single master mute button (in other words, whenever the master switch for a mute group is activated, any module assigned to that group will have its output muted). A “mute” LED indicator lights whenever a module has been muted. (The four mute master switches are located in the fader section of the board, directly underneath the power interface module in the center of the console.) Mix Minus Feeds the module’s signal to the console’s mix-minus system. Any module turned ON automatically feeds a signal to all eight mix-minus busses. Creation of a feed for IFB or remote use is done by simply pressing one or more of the eight mix-minus switches on the chosen input module’s fader panel, which removes that module's feed from the selected busses. Illuminated mix-minus switches thus show the dese- lected status directly at the input source. Note the mix-minus signal may be programmed (by an internal PCB-mounted slide switch) to be pre or post fader; a programming jumper permits the mix-minus feed to follow channel ON/OFF. See page 2-26, “Mix Minus” for details. Ready LED Used for line inputs; this tally LED is powered by an external source machine to indicate when it is cued-up and ready for play.

It may also be programmed to activate tallies and mutes (4) and timer restart; DB-9 control ports let the switch control (or be controlled by) external devices. See this chapter, “Input Module External Control Ports” and “Input Module Logic Programming” for a complete discussion. Bus Minus® Foldback In addition to the eight bus mix-minus system previously described, each input module can also produce its own independent mix-minus feed, called Bus Minus®. This is accomplished by pressing the Bus-Minus IN switch, which places a summed version of the module’s signal onto a special dedicated ACN mix bus, where it becomes available to other modules for use in their own Bus-Minus functions. A rotary level control (FB or foldback) outputs the dedicated ACN bus mix—with or without the module’s own signal, depending on the setting of the +/- switch (see immediately following)—to a connector on the module’s rear panel. The “+/-” switch, when pressed, illuminates and removes the module’s signal only from its own bus-minus output—the signal feed to the ACN mix bus (and other modules) remains unaffected. A TB switch (programmable to feed pre or post FB level control) sends console talkback audio to the module’s bus-minus output, which may be monitored at any time by a SOLO switch. (See page 2-26, “Bus Minus®” section, for programming details.) Metering Each individual input channel has its own 7-segment LED VU ladder built in to that channel’s fader panel. This LED VU may be internally programmed to monitor pre or post fader. It is always, however, pre channel ON/OFF, allowing it to function as a signal present indicator. The VU ladder is calibrated via a PCB-mounted trimpot on the fader panel’s main printed circuit board (“CR1” – see “FPI-1000” load sheet on page 49 of the Technical Drawings, center left). Note a single PEAK LED indicator at the bottom of the main module faceplate also warns of overload transients (it monitors both pre and post fader). Input channels may also be metered at the console’s SOLO VU meter pair in the console overbridge, just above the VU/Oscillator module. The SOLO meters may be driven pre or post fader, depending on whether the module’s CUE (PFL) or SOLO (AFL) switches are pressed. TV1 / May 98

page 2 – 23 TV1 / Oct 98 Input Module Control Ports The MI-1000 input module has two control ports: one for micro- phone sources (“MIC LOGIC”), the other for line sources (“MA- CHINE CTRL”). Each has its own DB-9 connector mounted on the module’s rear panel. Control functions are input specific; that is, programming jump- ers on the module’s switch PCB (SISW-1000) activate them for Line 1 and/or Line 2, and programming jumpers on the module’s main PCB activate them for Mic 1 and/or Mic 2. EXAMPLE: A logic enable jumper for L2 has been installed (but not one for L1). When L2 is selected at the top of the module, and the module’s Channel ON switch is pressed, then control functions will take place for any source machine hooked up to the Machine Ctrl DB-9 connector. However, if L1 is preselected and the channel is turned ON, nothing will take place at the source machine wired to the control connector. Generally speaking, input port control jumpers (zero ohm resistors) are already installed at the factory as required by client specifications, How- ever, should you wish to install your own see jumpers J5 and J6, Technical Drawings “MI-1000 Switch Card” load sheet (page 35, right center), for line inputs (Line 1: J6, Line 2: J5), and jumpers J1 and J2, Technical Drawings “MI-1000 Main Card” load sheet (page 30, right center) for mic inputs (Mic 1: J1, Mic 2: J2). MIC LOGIC DB-9 connector Functions (for Mic Sources): To Turn the Module ON & OFF from a Remote Location REMOTE ON – Activates the module’s CHANNEL ON switch. Provide a momentary closure between pins 1 and 7. This will latch the module ON. (User-supplied momentary contact switch required.) REMOTE OFF – De-activates the module’s CHANNEL ON switch. Provide a momentary closure between pins 1 and 9. This will latch the module OFF. (User-supplied momentary contact switch required.) COUGH (Momentary OFF) – Provide a closure between pin 3 and pin 1. This will turn the module OFF. Note this is a non-latching mode; the module will turn on again as soon as the closure stops. (User- supplied momentary contact switch required.) Talkback to Control Room (TB to CR) Lets talent at a remote location talk to the console operator instead of having his mic signal go out “live”. In this case a user-supplied momentary action TALKBACK switch is required for the remote microphone, where a closure between pins 1 and 2 does two things: (a) the module’s PFL signal is placed on the console’s CUE bus (where it may be heard by the console operator) and (b) the module’s COUGH function is simultaneously activated, to prevent the TB signal from going out over other assigned busses (i.e., “live”). This non-latching condition continues until the external TB switch is released. The module’s MIC LOGIC DB-9 connector (B) is directly below DB-25 connector A M U T E F O L L O W A I O MACHINE CTRL M U T E F O L L O W L O G I C M I C B Refer to the pintout diagrams on page 2-29 in conjunction with the text of this section.

page 2 – 24 TV1 / Oct 98 On Tally Lets the module’s channel ON switch control an on-air light or other “microphone on” indicator at a remote location. This opto-isolated control function provides a continuous closure between pin 4 (ON TALLY) and pin 1 (GND) whenever the module’s channel ON switch is pressed. This closure can be used to control an externally powered tally light that requires a continuous closure to function. Or an external tally light (i.e., LED) can be powered from the input module by connecting the external LED to pin 6 (+5V) and pin 4 (ON TALLY). In either case, the current is not to exceed 50 milliamps. MACHINE CTRL DB-9 connector Functions (for Line Sources): To START & STOP a Remote Source Machine Using the Module’s Channel ON Switch: Machine START – The remote source machine’s external on pins are wired to the console input module’s DB-9 CONTROL connector pins 2 (START) and 1 (MACHINE COMMON). Whenever the module’s channel ON switch is activated, the remote machine will start playing. Machine STOP – The remote source machine’s external off pins are wired to the console input module’s DB-9 CONTROL connector pins 3 (STOP) and 1 (MACHINE COMMON). Whenever the module’s channel ON switch is deactivated, the remote machine will stop playing. EFS ON/OFF – This control function is designed to run European type source machines (as opposed to the American MACHINE START/ STOP functions called out above). When the module is on, a constant closure occurs between DB-9 pins 4 (EFS ON/OFF) and 1 (MACHINE COMMON). An External Source Machine Turns the Module ON & OFF REMOTE ON – Activates the module’s CHANNEL ON switch. A momentary closure between pins 6 and 7 will latch the module ON. (Can be activated by external source machine control pulses.) REMOTE OFF – De-activates the module’s CHANNEL ON switch. A momentary closure between pins 6 and 9 will latch the module OFF. (Can be activated by external source machine control pulses.) Ready LED The module’s fader panel has a green ready LED next to the channel ON switch. This LED can be powered by an external source machine to indicate when that machine is cued up and ready for play. The LED hookup pins are 8 (+) and 5 (–) [5VDC nominal].

page 2 – 25 TV1 / Oct 98 Input Module Logic Programming Mute/Tally The console has four separate MUTE control lines; each input module may be programmed to activate any of these via its channel ON switch. The MUTE control lines are used to shut off control room and studio monitor speakers whenever the microphone for that particular location is activated. The same MUTE control lines can also activate TALLY ports at the console’s control room monitor (CRM-1000) and studio monitor (STM-1000) modules (see pages 5-6 and 6-5). Input module programming is accomplished by PCB-mounted dipswitches located on the main module PCB. Note each of the channel’s inputs [M1/2, L1/2] may be programmed separately. See Technical Drawings “MI-1000” load sheet (page 30, lower right) and schematic (page 28, D-3). The input mute programming dipswitches are: Mic 1 – Dipswitch “SW15” Mic 2 – Dipswitch “SW16” Line 1 – Dipswitch “SW18” Line 2 – Dipswitch “SW19” NOTE on those input modules with an associated preselector panel, each preselector input can also be programmed to mute separately. The eight associated preselector panel dipswitches are “SW1” through “SW8” on the preselector panel PCB. See Technical Drawings “SB- 1000” load sheet (page 145, center) and schematic (page 144, B-3). GROUP MUTES MUTE FOLLOW (PCB slide switch “SW17”) – Mute/Tally functions are normally programmed to follow the module’s channel ON switch. However, this PCB slide switch allows the mute/ tally functions to follow the console’s four Mute Masters (A thru D, see page 8-12). Thus, when “SW17” is reprogrammed to the right (“GR mutes mute follow”) whenever an input module is muted via the group mute masters, it’s programmed mute/tally functions are automatically deactivated. See Technical Drawings “MI-1000” load sheet (page 30, lower right) and schematic (page 28, D-3). Cue Dropout Input modules may be programmed to automatically drop out of Cue mode whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW13”. See Technical Drawings “MI-1000” load sheet (page 30, lower right) and schematic (page 28, A-5).

page 2 – 26 TV1 / Oct 98 Timer Restart Input modules may be programmed to automatically reset the console’s digital timer to zero and start it counting up whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW14”. See Technical Drawings “MI-1000” load sheet (page 30, lower right) and schematic (page 28, C-1). Mix Minus The input module’s summed mix-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW18”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, lower left) and schematic (page 46, C-5). The default setting is “post”. The input module’s summed mix-minus assign signal may also be programmed to follow the channel ON switch via a programming jumper (“J1”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings “FPI-1000” load sheet (page 49, left center) and schematic (page 46, dead center). Bus Minus® The input module’s summed bus-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW19”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, lower left) and schematic (page 46, C-5). The default setting is “post”. The input module’s summed bus-minus assign signal may also be programmed to follow the channel ON switch via a programming jumper (“J2”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings “FPI-1000” load sheet (page 49, left center) and schematic (page 46, C-5). The talkback feed to the module’s bus-minus output may be programmed to be pre or post the foldback (FB) level control via a PCB-mounted slide switch (“SW20”) on the module’s fader panel main PCB. See Technical Drawings “FPI-1000” load sheet (page 49, lower right) and schematic (page 46, D-3). The default setting is “post”. LED VU ladder The input module’s mono LED VU meter signal may be pro- grammed pre or post fader via a PCB-mounted slide switch (“SW17”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, extreme left) and schematic (page 46, B-7). The default setting is “pre”, which allows the meter to act as a “signal present” indicator. TV1 / May 98

page 2 – 27 TV1 / Oct 98 AUX Sends Aux sends may be programmed in pairs to follow the module’s channel ON switch regardless of their individual front panel pre/post fader switch settings (this is the default setting). This is accomplished by PCB-mounted slide switches (SW 34-37) on the module’s switchcard PCB. See Technical Drawings “MI-1000 Switch Card Load Sheet” (page 35, center right) and schematic (page 32, A-4 thru D-4). The programming switches are: Aux send 1/2 pre on/off follow: SW37 Aux send 3/4 pre on/off follow: SW36 Aux send 5/6 pre on/off follow: SW35 Aux send 7/8 pre on/off follow: SW34 Mute Link The TV-1000 console mute link system is designed to activate mute/tally functions ONLY when a live microphone signal is present on-the-air (i.e., live at the console’s Stereo 1 master output). Individual input channels can be programmed to be part of the mute link signal chain via PCB-mounted slide switch “SW38”. The default setting is mute link DEACTIVATED. See Technical Drawings “MI-1000 Switch Card Load Sheet” (page 35, center right) and schematic (page 34, C-6). Note this slide switch is reached through a cutout in the switchcard PCB. Each input module also has a “machine link defeat” PCB-mounted slide switch (“SW40”), which allows machine control port functions to be part of the mute link system chain. In other words, when machine link is enabled machine control functions will only take place when a Mute Link condition has been met (i.e., the source machine is live at Stereo Master 1, or “On-Air”. NOTE the default factory setting is machine link DEACTIVATED. See Technical Drawings “MI-1000 Switch Card Load Sheet” (page 35, center right) and schematic (page 32, D-3). The switch is reached through a cutout in the switchcard PCB. Event Computer Start/Stop/Timer Enable When the TV-1000 console’s event computer takes a snapshot of switch settings on an input module, the channel ON switch state is included in the event storage. When the event is called up at a future time, the module may be turned ON or OFF depending on the snapshot and the current state of the module. If the module is programmed to fire an external source machine (via machine start/stop functions, see page 2-24) a PCB-mounted slide switch on the module’s switchcard (“SW39” on PCB SISW-1000) gives you a choice of having the machine functions (AND the timer restart function) enabled or defeated for the event call-up. See Technical Drawings “MI-1000 Switch Card Load Sheet” (page 35, center right) and schematic (page 32, B-2). The switch is reached through a cutout in the switchcard PCB.

page 2 – 28 TV1 / Oct 98 Mute Follow Connector The module’s MUTE FOLLOW DB-9 connector, located at the top of the rear panel, is used to transmit muting and tally control signals between the module proper and it’s optional preselector panel in the console’s overbridge. It is wired pin-for-pin to a matching connector mounted behind each preselector, on the rear face of the console meterbridge. Actual preselector mute/tally programming is done through PCB- mounted dipswitches (eight; one for each source) on each preselector panel switchcard. See Technical Drawings, “SB-1000 Smart Button” schematic (page 144) and load sheet (page 145). Input Module Audio Wiring All audio wiring for the mono mic/line input module is via a single DB-25 connector (I/O “A”) mounted on the module’s rear panel. Audio signals include mic and line inputs, insert point wiring, direct out, and bus minus out. See drawing on next page for detailed pinouts. Parts Lists MI-1000 mono mic/line input module parts lists may be found in Chapter 10. See contents on page 2-3 for specific list locations. Printed Circuit Board Load Sheets Load sheet drawings, showing all part locations, are in the Techni- cal Drawings booklet (see contents on page 2-3 for specific drawing locations). Schematics Schematic drawings are also in the Technical Drawings booklet (see contents on page 2-3 for specific drawing locations).

page 2 – 30 TV1 / May 98 Stereo Line Inputs General SI-1000 input modules accept and output stereo signals; each module can select one of four stereo line level source signals. Each input channel consists of three separate panels mounted in a single mainframe position: a) the main module itself (far right), b) a fader panel directly in line with and below the main module (physically separated by the console’s alpha- numeric source display strip), and c) an (optional) 8-bank preselector switching panel located directly above each channel in the meterbridge overbank section. Input channel audio I/O (input/output) connections are made via two DB-25 multi-pin connectors (“A” upper; “B” lower) located on the back rear panel of each main module. Input channel logic and control signals are made through a DB-9 “Control” connector directly below the two DB-25 audio connectors (see page 2-36). An additional DB-9 connector, “mute follow”, is mounted on each rear panel; it is used to allow preselector sources to activate the console’s four mute/tally signals. Note console preselector panel switches do not control audio directly. Instead, they send control pulses to separate rackmounted switching cages (“Smart Select®” cages). Actual audio source signals are wired directly to the rackmounted Smart Select® cages (via rear chassis-mounted DB-25 connector pairs); the cages then feed selected source signals back to the main input modules. For a better understanding of the text that follows, please refer to the signal flow diagram on page 36 of the Technical Drawings.

page 2 – 31 TV1 / May 98 Main Module Input section The upper section of this input module selects one of four stereo line inputs. The electronically balanced line input section has left and right center detent input gain controls (with PCB-mounted calibration trimpots for fine adjustment), left and right phase reverse switches and a patch point INSERT switch (stereo insert points are electronically balanced in and out). AUX Section This section taps eight summed (L+R) post-EQ auxiliary send signals from the main input channel and routes them to the console’s send ACN busses. There is a pre/post selector switch and an ON switch for each aux circuit. NOTE aux circuits may also be programmed to operate as left/right stereo pairs via PCB-mounted programming dipswitches (see page 2-39). Also, while aux pre/post switches nor- mally switch before or after both the channel fader AND channel On switch, special PCB-mounted slide switches (four per module) permit dual AUX pairs to follow main channel ON/OFF even when switched to “pre” (page 2-39). BAL/MIX Control – MODE Switch The center-detent BAL/MIX rotary control operates in conjunction with the module’s MODE switch. Here are the possible settings and functions: Stereo Mode (ST) – Default setting (MODE switch cap illumi- nates); the rotary control functions as a regular L/R stereo balance pot. Mono Mode (MN) – Rotary control functions as a pan pot (a L+R summed signal is panned L/R within the module’s stereo field). Right Mode (RT) – Rotary control pans the right channel signal L/R within the module’s stereo field. Left Mode (LT) – Rotary control pans the module’s left channel signal L/R within the module’s stereo field. Mix Mode (MIX) – The module is put into mono sum mode; the rotary control then determines the left-right makeup of the mono sum signal, which remains dead center within the stereo field (i.e., fully counterclockwise: left signal only; center detent: mono sum of equal strength left and right signals; fully clockwise: right signal only; intermediate settings: varying L/R signal strength mix ratios. Useful for setting the balance between field or studio voiceovers and field-recorded actuality audio.

page 2 – 32 TV1 / May 98 module’s left channel) a cardioid mic directed along the main axis of the sound to be recorded; the other a figure-eight mic (feeding the module’s right channel) aligned at right angles to the cardioid pickup . When these are fed through the MLS- 1000 module functioning in M/S mode, the rotary control will act as follows: when turned all the way to the left (counter- clockwise) the LT (cardioid) signal is sent to both left and right module channels and a central “middle” effect results; when turned right (clockwise) the RT (figure-eight) signal goes to left and “–RT” (out-of-phase RT) goes to right, resulting in a “side” effect. In center position the rotary control sends a “LT plus RT” signal to the module’s left channel and a “LT minus RT” signal to the module’s right channel. Intermediate settings produce combinations of the above.* Bus Assign Each input module may have its output assigned to any combi- nation of the console’s four stereo MASTERS and/or eight stereo SUBMASTERS. Equalization Section A four-band stereo EQ/filter section is included, employing 3 sweep frequency peaking sections (each ±16dB with reciprocal curves) plus sweep frequency (-12dB/octave slope) low pass (2.7KHz-26KHz) and high pass (12Hz to 260Hz) filters. Note the three-band EQ and HI/LO pass filter sections may be switched in and out separately. Peak LED A peak reading LED indicator lights to indicate overload condi- tions within the channel circuitry (the indicator monitors both pre and post fader points in the signal chain). Cue and Solo Both pre-fader CUE and post-fader/post-channel on SOLO functions are provided. These switches tap the module’s PFL and AFL signals and route them to the console’s stereo SOLO/CUE monitor bus, where they may be used to feed operator headphones, control room monitors, dedicated speakers, etc. (SOLO/CUE is mastered at the console’s control room monitor module; see Chapter 5.)

page 2 – 33 TV1 / May 98 Preselector Panel TV-1000 input modules may be supplied with optional overbridge preselector panels. These consist of an eight-bank switch array that determines the source signal being fed to the main module’s Line 1 input. As stated before, preselector panels do not control audio directly; they send control pulses to switcher cards mounted in a separate rackmount Smart Select® cage. The cage card then returns the appro- priate signal to the module. See pages 8-5 thru 8-8 for smart cage wiring details. TV-1000 consoles may also be ordered with overbridge preselector panels that interface directly with a station switcher rather than a Smart Select® cage. The operation principle remains the same; the preselector switch sends a control pulse to the station switcher, which then selects and returns the appropriate audio signal to the module. Note preselector panel switches can be programmed (through the Wheatstone RCC Event Computer’s separate keyboard and monitor) to display 4-character alpha-numeric source codes that signify which source has been selected. These codes are displayed on the console’s source display strip, located just above the console’s fader panels. Note the source display will follow the main module’s input selector switches (i.e., Line 1, Line 2, Line 3, Line 4); however, when Line 1 is selected at the module, the source display will show the currently selected preselector panel’s source code. Smart Select® cage and Event Computer operation is covered in a separate technical manual (“The Wheatstone Router Control Sytstem”). Input Fader Panel Each input module has an associated fader panel located directly below it. Starting from the bottom, these panels are configured as follows: Fader A 3000 Series Penny & Giles long-throw (104mm) stereo fader. Plug-in for easy servicing. Mute Groups Each input channel may be assigned to any or all of four Mute Control Groups. These groups (A thru D) can then be muted by the press of a single master mute button (in other words, whenever the master switch for a mute group is activated, any module assigned to that group will have its output muted). A “mute” LED indicator lights whenever a module has been muted. (The four mute master switches are located in the fader section of the board, directly underneath the power interface module in the center of the console.)

page 2 – 34 TV1 / May 98 Mix Minus Feeds the module’s signal to the console’s mix-minus system. Any module turned ON automatically feeds a signal to all eight mix-minus busses. Creation of a feed for IFB or remote use is done by simply pressing one or more of the eight mix-minus switches on the chosen input module’s fader panel, which removes that module's feed from the selected busses. Illuminated mix-minus switches thus show the dese- lected status directly at the input source. Note the mix-minus signal may be programmed (by an internal PCB-mounted slide switch) to be pre or post fader; a programming jumper permits the mix-minus feed to follow channel ON/OFF. See page 2-38, “Mix Minus” for details. Ready LED Used for line inputs; this tally LED is powered by an external source machine to indicate when it is cued-up and ready for play. Channel ON This momentary action lighted pushbutton switch turns the input channel on and off. It may also be programmed to activate tallies and mutes (4) and timer restart; a DB-9 control port lets the switch control (or be controlled by) external devices. See this chapter, “Input Module External Control Ports” and “Input Module Logic Programming” for a complete discussion. Bus Minus® Foldback In addition to the eight bus mix-minus system previously described, each input module can also produce its own independent mix-minus feed, called Bus Minus®. This is accomplished by pressing the Bus- Minus IN switch, which places a summed version of the module’s signal onto a special dedicated ACN mix bus, where it becomes available to other modules for use in their own Bus-Minus functions. A rotary level control (FB or foldback) outputs the dedicated ACN bus mix—with or without the module’s own signal, depending on the setting of the +/- switch (see immediately following)—to a connector on the module’s rear panel. The “+/-” switch, when pressed, illumi- nates and removes the module’s signal only from its own bus-minus output—the signal feed to the ACN mix bus (and other modules) remains unaffected. A TB switch (programmable to feed pre or post FB level control) sends console talkback audio to the module’s bus-minus output, which may be monitored at any time by a SOLO switch. (See page 2-38, “Bus Minus®” section, for programming details.)

page 2 – 35 TV1 / May 98 Metering Each individual input channel has its own 7-segment LED sum VU ladder built in to that channel’s fader panel. This LED VU may be internally programmed to monitor pre or post fader. It is always, however, pre channel ON/OFF, allowing it to function as a signal present indicator. The VU ladder is calibrated via a PCB-mounted trimpot on the fader panel’s main printed circuit board (“CR1” – see “FPI-1000” load sheet on page 49 of the Technical Drawings, center left). Note a single PEAK LED indicator at the bottom of the main module faceplate also warns of overload transients (it monitors both pre and post fader). Input channels may also be metered at the console’s stereo SOLO VU meter pair in the console overbridge, just above the VU/Oscillator module. The SOLO meters may be driven pre or post fader, depending on whether the module’s CUE (PFL) or SOLO (AFL) switches are pressed.

page 2 – 36 TV1 / May 98 Input Module Control Port The SI-1000 input module has one DB-9 CONTROL port mounted at the bottom of the module’s rear panel. Control functions are input specific; that is, programming jumpers on the module’s switch PCB (SISW-1000) activate them for Lines 1 thru Line 4. EXAMPLE: A logic enable jumper for L2 has been installed (but not one for L1). When L2 is selected at the top of the module, and the module’s Chan- nel ON switch is pressed, then control functions will take place for any source machine hooked up to the Machine Ctrl DB-9 connector. However, if L1 is preselected and the channel is turned ON, nothing will take place at the source machine wired to the control connector. Generally speaking, input port control jumpers (zero ohm resistors) are already installed at the factory as required by client specifications, However, should you wish to install your own see jumpers J5 thru J8, Technical Draw- ings “SI-1000 Switch Card” load sheet (page 45, center right). Input ports are enabled as follows: Line 1: J8, Line 2: J7, Line 3: J6, Line 4: J5. To START & STOP a Remote Source Machine Using the Module’s Channel ON Switch: Machine START – The remote source machine’s external on pins are wired to the console input module’s DB-9 CONTROL connector pins 2 (START) and 1 (MACHINE COMMON). Whenever the module’s chan- nel ON switch is activated, the remote machine will start playing. Machine STOP – The remote source machine’s external off pins are wired to the console input module’s DB-9 CONTROL connector pins 3 (STOP) and 1 (MACHINE COMMON). Whenever the module’s channel ON switch is deactivated, the remote machine will stop playing. EFS ON/OFF – This control function is designed to run European type source machines (as opposed to the American MACHINE START/STOP functions called out above). When the module is ON, a constant closure occurs between DB-9 pins 4 (EFS ON/OFF) and 1 (MACHINE COM- MON). An External Source Machine Turns the Module ON & OFF REMOTE ON – Activates the module’s CHANNEL ON switch. A momentary closure between pins 6 and 7 will latch the module ON. (Can be activated by external source machine control pulses.) REMOTE OFF – De-activates the module’s CHANNEL ON switch. A momentary closure between pins 6 and 9 will latch the module OFF. (Can be activated by external source machine control pulses.) Ready LED The module’s fader panel has a green ready LED next to the channel ON switch. This LED can be powered by an external source machine to indicate when that machine is cued up and ready for play. The LED hookup pins are 8 (+) and 5 (–) [5VDC nominal]. The DB-9 CONTROL connector is mounted at the bottom of the module’s rear panel.

page 2 – 37 TV1 / May 98 Input Module Logic Programming Mute/Tally The console has four separate MUTE control lines; each input module may be programmed to activate any of these via its channel ON switch. The MUTE control lines are used to shut off control room and studio monitor speakers whenever the channel for that particular location is activated. The same MUTE control lines can also activate TALLY ports at the console’s control room monitor (CRM-1000) and studio monitor (STM-1000) modules (see pages 5-6 and 6-5). Input module programming is accomplished by PCB-mounted dipswitches located on the main module PCB. Note each of the channel’s inputs [L1 thru L4] may be programmed separately. See Technical Drawings “SI-1000” load sheet (page 44, lower right) and schematic (page 42, C-3). The input mute programming dipswitches are: Line 1 – Dipswitch “SW24” Line 2 – Dipswitch “SW25” Line 3 – Dipswitch “SW27” Line 4 – Dipswitch “SW28” NOTE on those input modules with an associated preselector panel, each preselector input can also be programmed to mute separately. The eight associated preselector panel dipswitches are “SW1” through “SW8” on the preselector panel PCB. See Technical Drawings “SB- 1000” load sheet (page 145, center) and schematic (page 144, B-3). GROUP MUTES MUTE FOLLOW (PCB slide switch “SW26”) – Mute/Tally functions are normally programmed to follow the module’s channel ON switch. However, this PCB slide switch allows the mute/ tally functions to follow the console’s four Mute Masters (A thru D, see page 8-12). Thus, when “SW26” is reprogrammed to the right (“GR mutes mute follow”) whenever an input module is muted via the group mute masters, it’s programmed mute/tally functions are automatically deactivated. See Technical Drawings “SI-1000” load sheet (page 44, lower right) and schematic (page 42, C-3). Cue Dropout Input modules may be programmed to automatically drop out of Cue mode whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW22”. See Technical Drawings “SI-1000” load sheet (page 44, lower right) and schematic (page 42, A-5). TV1 / Oct 98

page 2 – 38 TV1 / May 98 Timer Restart Input modules may be programmed to automatically reset the console’s digital timer to zero and start it counting up whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW23”. See Technical Drawings “SI-1000” load sheet (page 44, lower right) and schematic (page 42, C-1). Mix Minus The input module’s summed mix-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW18”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, lower left) and schematic (page 46, C-5). The default setting is “post”. The input module’s summed mix-minus assign signal may also be programmed to follow the channel ON switch via a programming jumper (“J1”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings “FPI-1000” load sheet (page 49, left center) and schematic (page 46, dead center). Bus Minus® The input module’s summed bus-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW19”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, lower left) and schematic (page 46, C-5). The default setting is “post”. The input module’s summed bus-minus assign signal may also be programmed to follow the channel ON switch via a programming jumper (“J2”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings “FPI-1000” load sheet (page 49, left center) and schematic (page 46, C-5). The talkback feed to the module’s bus-minus output may be programmed to be pre or post the foldback (FB) level control via a PCB-mounted slide switch (“SW20”) on the module’s fader panel main PCB. See Technical Drawings “FPI-1000” load sheet (page 49, lower right) and schematic (page 46, D-3). The default setting is “post”. Sum LED VU ladder The input module’s mono sum LED VU meter signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW17”) on the module’s fader panel main PCB. See Technical Drawings “FPI- 1000” load sheet (page 49, extreme left) and schematic (page 46, B-7). The default setting is “pre”, which allows the meter to act as a “signal present” indicator.

page 2 – 39 TV1 / May 98 AUX Sends The TV-1000 console aux SEND busses are normally configured as eight mono ACNs. However, they may be reprogrammed as left/right pairs if desired. This is accomplished by PCB-mounted slide switches on the module’s main PCB (SW 14-21). See Technical Drawings “SI-1000” load sheet (page 44, left center) and schematic (page 40, A-6 thru D-6). The programming switches are: Aux send 1 sum/left: SW14 Aux send 2 sum/right: SW 15 Aux send 3 sum/left: SW16 Aux send 4 sum/right: SW 17 Aux send 5 sum/left: SW18 Aux send 6 sum/right: SW 19 Aux send 7 sum/left: SW 20 Aux send 8 sum/right: SW 21 Note the above switches are reached through access cutouts in the module’s upper switchcard PCB. Aux send pairs may also be programmed to follow the module’s channel ON switch regardless of their individual front panel pre/post fader switch settings (this is the default setting). This is accomplished by PCB- mounted slide switches (SW 34-37) on the module’s switchcard PCB. See Technical Drawings “SISW-1000 Switch Card” load sheet (page 35, right center) and schematic (page 32, A-4 thru D-4). The programming switches are: Aux send 1/2 pre on/off follow: SW37 Aux send 3/4 pre on/off follow: SW36 Aux send 5/6 pre on/off follow: SW35 Aux send 7/8 pre on/off follow: SW34 Mute Link The TV-1000 console mute link system is designed to activate mute/ tally functions ONLY when a live microphone signal is present on-the-air (i.e., live at the console’s Stereo 1 master output). Individual input channels can be programmed to be part of the mute link signal chain via PCB-mounted slide switch “SW38”. The default setting is mute link DEACTIVATED. See Technical Drawings “SI-1000 Switch Card Load Sheet” (page 45, center right) and schematic (page 34, C-6). Note this slide switch is reached through a cutout in the switchcard PCB. Each input module also has a “machine link defeat” PCB-mounted slide switch (“SW40”), which allows machine control port functions to be part of the mute link system chain. In other words, when machine link is enabled machine control functions will only take place when a Mute Link condition has been met (i.e., the source machine is live at Stereo Master 1, or “On-Air”. NOTE the default factory setting is machine link DEACTI- VATED. See Technical Drawings “SI-1000 Switch Card Load Sheet” (page 45, center right) and schematic (page 32, D-3). The switch is reached through a cutout in the switchcard PCB. TV1 / Oct 98

page 2 – 40 TV1 / May 98 Event Computer Start/Stop/Timer Enable When the TV-1000 console’s event computer takes a snapshot of switch settings on an input module, the channel ON switch state is included in the event storage. When the event is called up at a future time, the module may be turned ON or OFF depending on the snapshot and the current state of the module. If the module is programmed to fire an external source machine (via machine start/stop functions, see page 2-36) a PCB- mounted slide switch on the module’s switchcard (“SW39” on PCB SISW-1000) gives you a choice of having the machine functions (AND the timer restart function) enabled or defeated for the event call-up. See Technical Drawings “SI-1000 Switch Card Load Sheet” (page 45, center right) and schematic (page 32, B-2). The switch is reached through a cutout in the switchcard PCB. Mute Follow Connector The module’s MUTE FOLLOW DB-9 connector, located at the top of the rear panel, is used to transmit muting and tally control signals between the module proper and it’s optional preselector panel in the console’s overbridge. It is wired pin-for-pin to a matching connector mounted behind each preselector, on the rear face of the console meterbridge. Actual preselector mute/tally programming is done through PCB- mounted dipswitches (eight; one for each source) on each preselector panel switchcard. See Technical Drawings, “SB-1000 Smart Button” schematic (page 144) and load sheet (page 145). Input Module Audio Wiring All audio wiring for the stereo line input module is via two DB-25 connectors mounted on the module’s rear panel. Audio signals include line inputs (upper connector “A”) and insert point wiring, direct out, and bus minus out (lower connector “B”). See drawing on next page for detailed pinouts. Parts Lists SI-1000 stereo line input module parts lists may be found in Chapter 10. See contents on page 2-4 for specific list locations. Printed Circuit Board Load Sheets Load sheet drawings, showing all part locations, are in the Technical Drawings booklet (see contents on page 2-4 for specific drawing loca- tions). Schematics Schematic drawings are also in the Technical Drawings booklet (see contents on page 2-4 for specific drawing locations).

page 3 – 3 TV1 / May 98 Submaster Module General TV-1000 audio consoles come equipped with eight stereo SUBMASTER modules. Each submaster module controls one stereo subgroup and houses the master circuitry for one console AUX SEND output and one console MIX MINUS output. There is an associated fader panel directly beneath each main module faceplate. Submaster audio I/O (input/output) connections are made via two DB-25 multi-pin connectors (“A” upper; “B” lower) located on the back rear panel of the module. Note submaster mono sum outputs (both pre and post) are available at the upper connector (see page 3-9). Please refer to the signal flow diagram on page 52 of the Technical Drawings in conjunction with the text of this chapter. Main Module Controls Aux Master Section The TV-1000 console has eight AUX send outputs; each of the console’s eight submaster modules contains the master controls for one console AUX send output. These controls consist of a master level pot, an ON switch, and a SOLO switch, which allows the console operator to spot monitor that particular AUX signal via the console’s SOLO interrupt circuit and SOLO/CUE VU meters. Note an AUX insert point is provided (it may be PCB- jumper bypassed if desired, see page 3-7). Mix Minus Master Section The TV-1000 console has eight MIX MINUS outputs; each of the console’s eight submaster modules contains the master con- trols for one console MIX MINUS output. These controls consist of a master level pot, an ON switch, and a SOLO switch, which allows the console operator to spot monitor that particular MIX MINUS signal via the console’s SOLO interrupt circuit and SOLO/CUE VU meters. +3 0 -3 -6 -9 +6 -12 -15 -18 -21 8 0 9 7 6 4 5 3 2 1 M A S T E R S 8 0 9 7 6 4 5 3 2 1 M X M 1 1 ON SOLO ON L R SUB 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 0 1 A U X 1 A U X 2 A U X 3 A U X 4 A U X 5 A U X 6 A U X 7 A U X 8 P R E O N O N O N O N O N O N O N O N 8 0 9 7 6 4 5 3 2 1 0 1 P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E 1 2 3 4 M S T R S AUX MXM SOLO CUE C B A L LT RT AUX MXM SUB TALK BACK 8 0 9 7 4 3 2 1 +3 0 -3 -6 -9 +6 -12 -15 -18 -21 A U X AUX MXM SUB PEAK V U T R I M SUB S O L O FADER PANEL 8 15 12 - - - - 3 0 3 + - 6 9 SUBMASTER SUM V V V VUU U U 0 5 10 15 20 30 40 50 60 70 00 MUTE A B C D M M M M IIII X X X X M M M M IIII N N N N UU U U SSS S 8 7 6 5 4 3 2 1 M M M M UU U U TTTT EEEE G G G G RRRR O O O O UU U U PPPP SSS S

page 3 – 4 TV1 / May 98 Mix Minus Confidence Feed This is a feature that interrupts regular Mix Minus outputs with a mono line level signal inputted at each submaster module’s rear panel upper DB-25 (“A”) audio connector. Individual interrupts are con- trolled by eight MIX MINUS CONFIDENCE FEED switches on a separate module. A ninth MASTER switch will interrupt all eight feeds simultaneously. VU Trims AUX and MIX MINUS (mono) outputs are metered via two 10- segment LED VU ladders at the bottom of the main module. These meters are calibrated by the AUX and MXM recessed front panel trimpots in the upper portion of the main module faceplate. The same VU trim section also contains left and right trimpots for the console’s meterbridge mounted submaster VU meters. AUX Section This section taps eight summed (but see NOTE immediately following) auxiliary send signals from the main submaster channel and routes them to the console’s send ACN busses. There is a pre/post selector switch and an ON switch for each aux circuit. NOTE aux circuits may also be programmed to operate as left/right stereo pairs via PCB-mounted programming dipswitches (see pages 3-7, 3-8). Also, while aux pre/post switches normally switch before or after both the channel fader AND channel On switch, special PCB-mounted slide switches (four per module) permit dual AUX pairs to follow submaster channel ON/OFF even when switched to “pre” (see page 3-8). Balance Pot Controls the left/right stereo submaster signal. Master Assign The module’s SUBMASTER signal may be further assigned to any of the TV-1000 console’s four stereo master outputs. Talkback Three TB switches (AUX, MXM and SUB) allow the console operator’s talkback microphone signal to be routed to each submaster module’s AUX, MIX MINUS and SUBMASTER outputs. LED VU Ladders These two meters monitor the module’s AUX and MIX MINUS outputs.

page 3 – 5 TV1 / May 98 Solo and Cue Both pre-fader CUE and post-fader SOLO switches are provided. These switches tap the module’s PFL and AFL signals and route them to the console’s stereo SOLO/CUE monitor bus, where they may be used to feed operator headphones, control room monitors, dedicated speakers, etc. (SOLO/CUE is mastered at the console’s control room monitor module; see Chapter 5.) Note CUE may be programmed to automatically drop out whenever the module’s ON switch (see fader panel section) is activated (see page 3-8, “Cue Dropout”). Submaster Insert Point (rear panel) The module’s rear panel has an electronically balanced stereo insert point in the submaster signal chain (lower DBD-25 connector “B”). It is normally PCB- jumper bypassed at the factory (see page 3-7). Fader Panel Controls Each submaster module has an associated fader panel located directly below it. Starting from the bottom, these panels are configured as follows: +3 0 -3 -6 -9 +6 -12 -15 -18 -21 8 0 9 7 6 4 5 3 2 1 M A S T E R S 8 0 9 7 6 4 5 3 2 1 M X M 1 1 ON SOLO ON L R SUB 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 0 1 A U X 1 A U X 2 A U X 3 A U X 4 A U X 5 A U X 6 A U X 7 A U X 8 P R E O N O N O N O N O N O N O N O N 8 0 9 7 6 4 5 3 2 1 0 1 P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E 1 2 3 4 M S T R S AUX MXM SOLO CUE C B A L LT RT AUX MXM SUB TALK BACK 8 0 9 7 4 3 2 1 +3 0 -3 -6 -9 +6 -12 -15 -18 -21 A U X AUX MXM SUB PEAK V U T R I M SUB S O L O FADER PANEL 8 15 12 - - - - 3 0 3 + - 6 9 SUBMASTER SUM V V V VUU U U 0 5 10 15 20 30 40 50 60 70 00 MUTE A B C D M M M M IIII X X X X M M M M IIII N N N N UU U U SSS S 8 7 6 5 4 3 2 1 M M M M UU U U TTTT EEEE G G G G RRRR O O O O UU U U PPPP SSS S Fader A 3000 Series Penny & Giles long-throw (104mm) stereo fader. Plug-in for easy servicing. Mix Minus Assign (optional) Feeds the module’s signal to the console’s mix-minus system. Any module turned ON automatically feeds a signal to all eight mix-minus busses. Creation of a feed for IFB or remote use is done by simply pressing one or more of the eight mix-minus switches on the chosen input module’s fader panel, which removes that module's feed from the selected busses. Illuminated mix-minus switches thus show the deselected status directly at the input source. The mix-minus signal may be programmed (by an internal PCB- mounted slide switch) to be pre or post fader; a programming jumper permits the mix-minus feed to follow channel ON/OFF. See page 3-7, “Mix Minus” for details. Channel ON This momentary action lighted pushbutton switch turns the module’s submaster signal on and off. Sum VU An LED ladder display that meters the module’s submaster summed L+R output. Note the meter may be programmed (by an internal PCB-mounted slide switch, see page 3-7) to monitor pre or post fader. It is always, however, pre channel ON/OFF, allowing it to function as a signal present indicator. TV1 / Oct 98

page 3 – 6 TV1 / May 98 Mute Group Assign Each submaster module may be assigned to any or all of four Mute Control Groups. These groups (A thru D) can then be muted by the press of a single master mute button (in other words, whenever the master switch for a mute group is activated, any module assigned to that group will have its output muted). A “mute” LED indicator lights whenever a module has been muted. (The four mute master switches are located in the fader section of the board, directly underneath the power interface module in the center of the console.) Metering Submasters In standard mainframe configurations, each of the console’s eight submaster modules has a dedicated stereo VU meter pair mounted in the console meterbridge. These monitor the submaster signal as it outputs the console. Recessed front panel access VU calibration trimpots near the top of the module (“SUB L-R”) permit calibration. A SUB PEAK LED is included at the bottom of the main module faceplate. Submaster fader panels also have built-in mono sum LED VU ladders with PCB-mounted calibration trimpots. Like all signals on the console, submasters can be metered (PFL or AFL) at the stereo SOLO meter pair. Mix-Minus and Auxiliary Sends Submaster modules house the console’s eight MXM and AUX masters. Thus each module has two 10-segment front panel LED VU ladders: one monitoring that module’s mix-minus output and the other that same module’s auxiliary send output (both are mono signals). Submaster Module Internal Programming AUX Solo The module’s AUX signal is mono; the console’s SOLO circuit is stereo. PCB dipswitch “SW16” positions 1 (LT) and 2 (RT) (see Technical Drawings SG-1000 schematic page 58 B-3, and PCB load sheet page 60 lower right) determine whether the mono AUX signal goes onto the left and/or right SOLO busses. AUX Insert Bypass The module’s mono AUX signal electronically balanced insert point is normally bypassed at the factory via PCB jumpers “J6” (high) and “J7” (low; see Technical Drawings SG-1000 schematic page 54 D-6, and PCB load sheet page 60 extreme lower left). If you wish to use this patch point it will be necessary to remove the pre-installed jumpers. +3 0 -3 -6 -9 +6 -12 -15 -18 -21 8 0 9 7 6 4 5 3 2 1 M A S T E R S 8 0 9 7 6 4 5 3 2 1 M X M 1 1 ON SOLO ON L R SUB 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 8 0 9 7 6 4 5 3 2 1 0 1 0 1 A U X 1 A U X 2 A U X 3 A U X 4 A U X 5 A U X 6 A U X 7 A U X 8 P R E O N O N O N O N O N O N O N O N 8 0 9 7 6 4 5 3 2 1 0 1 P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E P R E 1 2 3 4 M S T R S AUX MXM SOLO CUE C B A L LT RT AUX MXM SUB TALK BACK 8 0 9 7 4 3 2 1 +3 0 -3 -6 -9 +6 -12 -15 -18 -21 A U X AUX MXM SUB PEAK V U T R I M SUB S O L O FADER PANEL 8 15 12 - - - - 3 0 3 + - 6 9 SUBMASTER SUM V V V VUU U U 0 5 10 15 20 30 40 50 60 70 00 MUTE A B C D M M M M IIII X X X X M M M M IIII N N N N UU U U SSS S 8 7 6 5 4 3 2 1 M M M M UU U U TTTT EEEE G G G G RRRR O O O O UU U U PPPP SSS S TV1 / Oct 98

page 3 – 7 TV1 / May 98 Mix Minus Solo The module’s MXM signal is mono; the console’s SOLO circuit is stereo. PCB dipswitch “SW16” positions 3 (LT) and 4 (RT) (see Technical Drawings SG-1000 schematic page 58 B-3, and PCB load sheet page 60 extreme lower right) determines whether the mono MXM signal goes onto the left and/or right SOLO busses. Submaster Insert Bypass The module’s stereo SUBMASTER electronically balanced insert points may be bypassed via PCB jumpers “J2” (RT hi), “J3” (RT lo), “J4” (LT hi) and “J5” (LT lo). (See Technical Drawings SG-1000 schematic page 53 D-5 & B-5, and PCB load sheet page 60 lower left). Mix Minus The submaster module’s summed mix-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW18”) on the module’s fader panel main PCB. See Technical Drawings FPO- 1000 load sheet (page 75, lower left) and schematic (page 72 C-5). The default setting is “post”. The submaster module’s summed mix-minus assign signal may also be programmed to follow the submaster channel ON switch via a program- ming jumper (“J1”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings FPO-1000 load sheet (page 75, left center) and schematic (page 72, C-5). Sum LED VU The submaster module’s mono sum LED VU meter signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW17”) on the module’s fader panel main PCB. See Technical Drawings FPO- 1000 load sheet (page 75, far left) and schematic (page 72, left center). The default setting is “post”. AUX Sends The TV-1000 console aux send busses are normally configured as eight mono ACNs. However, they may be programmed as left/right pairs if desired. This is accomplished by PCB-mounted slide switches on the module’s main PCB (SW 7-14). See Technical Drawings SG-1000 load sheet (page 60, left center) and schematic (page 56, A-6 thru D-6). The AUX send programming switches are as follows: Aux send 1 sum/left: SW7 Aux send 2 sum/right: SW 8 Aux send 3 sum/left: SW9 Aux send 4 sum/right: SW 10 Aux send 5 sum/left: SW11 Aux send 6 sum/right: SW 12 Aux send 7 sum/left: SW 13 Aux send 8 sum/right: SW 14 NOTE insert bypass jump- ers are normally pre-in- stalled at the factory. If you intend to use an out- board processing loop, you must remove the jumpers. TV1 / Oct 98

page 3 – 8 TV1 / May 98 I O I O A B The module’s two DB-25 connectors (A & B) handle all input/output signals. Note the preceding switches are reached through access cutouts in the module’s upper switchcard PCB. Aux send pairs may also be programmed to follow the module’s channel ON switch regardless of their individual front panel pre/post fader switch settings (this is the default setting). This is accomplished by PCB- mounted slide switches on the module’s switchcard PCB (SW 24-27). See Technical Drawings SGSW-1000 load sheet (page 65, lower right) and schematic (page 61, A-2 thru D-2). The programming switches are: Aux send 1/2 pre on/off follow: SW27 Aux send 3/4 pre on/off follow: SW26 Aux send 5/6 pre on/off follow: SW25 Aux send 7/8 pre on/off follow: SW24 Cue Dropout Submaster modules may be programmed to automatically drop out of Cue mode whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW15”. See Technical Drawings SG-1000 load sheet (page 60, lower right) and schematic (page 58 C-3). Submaster Module Audio Wiring All audio wiring for the submaster module is via two DB-25 connectors mounted on the module’s rear panel (see right). Audio signals include stereo and mono sum submaster outputs, aux and mix minus outputs, confidence feed line in (upper connector “A”) and submaster and aux insert points (lower connector “B”). See pinout drawing on next page for wiring details. Parts Lists SG-1000 stereo submaster module parts lists may be found in Chapter 10. See “Chapter Contents” page 3-2 for specific list locations.

page 4 – 3 TV1 / May 98 Stereo Master Module General TV-1000 audio consoles come equipped with four stereo MASTER modules. Each master module controls one of the console’s main stereo outputs. There is an associated fader panel directly beneath each main module faceplate. Stereo master audio I/O (input/output) connections are made via two DB-25 multi-pin connectors (“A” upper; “B” lower) located on the back rear panel of the module (see page 4-8). Please refer to the signal flow diagram on pages 68 and 69 of the Technical Drawings in conjunction with the text of this chapter. Note stereo MASTER modules utilize the same printed circuit boards as SUBMASTER modules. Main Module Controls VU Trims These recessed front panel trimpots may be used to calibrate the module’s main VU meter pair (“Master”) and mono sum LED VU (located on the associated fader panel). AUX Section This section taps eight summed (but see NOTE immediately following) auxiliary send signals from the module and routes them to the console’s send ACN busses. There is a pre/post selector switch and an ON switch for each aux circuit. NOTE aux circuits may also be programmed to operate as left/right stereo pairs via PCB-mounted programming dipswitches (see page 4-7). Also, while aux pre/post switches normally switch before or after both the channel fader AND channel On switch, special PCB- mounted slide switches (four per module) permit dual AUX pairs to follow stereo master channel ON/OFF even when switched to “pre” (see page 4-7).

page 4 – 4 TV1 / May 98 Balance Pot Controls the left/right stereo master signal. Master 1 & 2 Assign (Modules 3 & 4 only) Master module signals 3 & 4 may be back-assigned to Masters 1 & 2 for grand mastering situations. Outputs Master modules have three main outputs: stereo master, mono sum (pre), and mono sum (post). Stereo Master module #1 also has an additional LINE OUTPUT tapped off the stereo master out (see “Stereo Master Interrupt” immediately following). Stereo Master Interrupt (Module 1 only) This feature interrupts the #1 stereo master module’s LINE OUT- PUT with a mono line level signal inputted at the module’s rear panel upper DB-25 (“A”) audio connector. The interrupt is turned on and off by a STEREO MASTER INTERRUPT switch on a separate confi- dence feed panel. It may also be turned off (but not on) by a user- supplied external “Tone Off” switch wired to control pins on that module’s rear panel (see pages 8-9 and 8-10). Peak LED Monitors the module’s stereo master signal (both pre and post) for overload transient peaks. Solo and Cue Both pre-fader CUE and post-fader SOLO switches are provided. These switches tap the module’s PFL and AFL signals and route them to the console’s stereo SOLO/CUE monitor bus, where they may be used to feed operator headphones, control room monitors, dedicated speakers, etc. (SOLO/CUE is mastered at the console’s control room monitor module; see Chapter 5.) Note CUE may be programmed to automatically drop out whenever the module’s ON switch (see fader panel section) is activated (see “Cue Dropout,” page 4-7). Insert Point (rear panel) The module’s rear panel has an electronically balanced stereo insert point in the stereo master signal chain (lower DBD-25 connector “B”). It is normally PCB-jumper bypassed at the factory (see page 4-6).

It is always, however, pre channel ON/OFF, allow- ing it to function as a signal present indicator. Mute Group Assign The module may be assigned to any or all of four Mute Control Groups. These groups (A thru D) can then be muted by the press of a single master mute button (in other words, whenever the master switch for a mute group is activated, any module assigned to that group will have its output muted). A “mute” LED indicator lights whenever a module has been muted. (The four mute master switches are located in the fader section of the board, directly underneath the power interface module in the center of the con- sole.)

page 4 – 6 TV1 / May 98 Metering Stereo Masters Like inputs and submasters, stereo master fader panels have built- in mono sum LED VU ladders with PCB-mounted calibration trimpots. They may also be metered (PFL or AFL) at the stereo SOLO meter. However, they additionally have dedicated L-R VU meter pairs in the console’s meterbridge (these are calibrated by recessed trimpots at the top of each stereo master module faceplate). A PEAK LED indicator is also mounted at the bottom of the main module faceplate. Master Module Internal Programming Master Insert Bypass The module’s stereo master electronically balanced insert points may be bypassed via PCB jumpers “J2” (RT hi), “J3” (RT lo), “J4” (LT hi) and “J5” (LT lo) (See Technical Drawings SG-1000 schematic page 53 D-5 & B-5, and PCB load sheet page 60 lower left). Mix Minus The master module’s summed mix-minus assign signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW18”) on the module’s fader panel main PCB. See Technical Drawings FPO-1000 load sheet (page 75, lower left) and schematic (page 72 C-5). The default setting is “post”. The stereo master module’s summed mix-minus assign signal may also be programmed to follow the module’s channel ON switch via a programming jumper (“J1”) on the module’s fader panel main PCB (this is the default setting). See Technical Drawings FPO-1000 load sheet (page 75, left center) and schematic (page 72, C-5). Sum LED VU The stereo master module’s mono sum LED VU meter signal may be programmed pre or post fader via a PCB-mounted slide switch (“SW17”) on the module’s fader panel main PCB. See Technical Drawings FPO-1000 load sheet (page75, far left) and schematic (page 72, left center). The default setting is “post”. Insert jumpers are normally al- ready installed at the factory.

page 4 – 7 TV1 / May 98 AUX Sends The TV-1000 console aux send busses are normally configured as eight mono ACNs. However, they may be programmed as left/right pairs if desired. This is accomplished by PCB-mounted slide switches on the module’s main PCB (SW 7-14). See Technical Drawings SG- 1000 load sheet (page 60, left center) and schematic (page 56, A-6 thru D-6). The programming switches are: Aux send 1 sum/left: SW7 Aux send 2 sum/right: SW 8 Aux send 3 sum/left: SW9 Aux send 4 sum/right: SW 10 Aux send 5 sum/left: SW11 Aux send 6 sum/right: SW 12 Aux send 7 sum/left: SW 13 Aux send 8 sum/right: SW 14 Note the above switches are reached through access cutouts in the module’s upper switchcard PCB. Aux send pairs may also be programmed to follow the module’s channel ON switch regardless of their individual front panel pre/post fader switch settings (this is the default setting). This is accomplished by PCB-mounted slide switches on the module’s switchcard PCB (SW 24-27). See Technical Drawings SGSW-1000 load sheet (page 65, lower right) and schematic (page 61, A-2 thru D-2). The programming switches are: Aux send 1/2 pre on/off follow: SW27 Aux send 3/4 pre on/off follow: SW26 Aux send 5/6 pre on/off follow: SW25 Aux send 7/8 pre on/off follow: SW24 Cue Dropout Master modules may be programmed to automatically drop out of Cue mode whenever the channel On switch is pressed (this is the default setting). This is accomplished by PCB-mounted slide switch “SW15”. See Technical Drawings SG-1000 load sheet (page 60, lower right) and schematic (page 58 C-3). TV1 / Oct 98

page 4 – 8 TV1 / May 98 I O I O A B The module’s two DB-25 connectors (A & B) handle all input/output signals. Master Module Input/Output Wiring All wiring for the master modules is via two rear panel DB-25 connectors (see right). Signals include stereo and mono sum master outputs, external tone in, external tone control lines (upper connector “A”) and master insert points (lower connector “B”).

page 5 – 2 TV1 / May 98 Control Room Module General TV-1000 audio consoles are equipped with a CR-1000 control room monitor module. The control room module allows the console operator to monitor the TV-1000 console’s inputs and outputs by means of a monitor source select switchbank and the console’s SOLO/CUE sys- tem. It is also the module that houses the console’s on-air tally port. Input channel audio I/O (input/output) connections are made via two DB-25 multi-pin connectors (“A” upper; “B” lower) located on the back rear panel of the module. Tally logic and control signals are made through a DB-9 “TALLIES” connector directly above the rear panel’s two DB-25 audio connectors (see page 5-6). Note the CR-1000 module has a blank FPCR panel in its “fader” position. This panel has active circuitry behind it that feeds the console’s SOLO ACN signal to the module proper. Please refer to the signal flow diagram on page 83 of the Technical Drawings in conjunction with the text of this chapter. Controls VU Trims Two pairs of recessed, front panel trimpots are used to calibrate the console’s SOLO/CUE VU feed and optional CR (control room monitor signal) VU meters. NOTE while the console’s SOLO/CUE master circuitry is located on the CR module, solo meter VU driver circuitry is actually on the console’s VO- 1000 module. The CR module’s SOLO/CUE trimpots adjust the signal feed going from the CR module to the VO module’s solo/external VU meter drivers (which have their own trimpots; see page 7-3). Solo/Cue and External Cue Level Controls The solo/cue master level control sets the loudness for the console’s CR and HDPN solo/cue interrupt signals. An external cue pot sets the level for the console’s separate solo/cue outputs: one electronically balanced line level out and the other driven by built-in cue speaker amps. The speaker outputs may be stereo or L+R summed. Monitor Select These source select switches allow the console operator to monitor the console’s eight aux sends, eight submasters and four master outputs. Four additional external line inputs may also be accessed.

page 5 – 3 TV1 / May 98 Headphone Section The module’s headphone circuit follows the monitor source select switching. There are two headphone outputs: one electronically bal- anced line level out (programmable as either pre or post HDPN level control), and the other driven by a built-in amplifier (amplifier output may be stereo or L+R summed). Note the headphone outputs are normally subject to the console’s muting and solo/cue interrupt cir- cuits; however, these may be defeated by front panel switching if desired. CR Section Control room output is determined by the module’s monitor source select switching and is subject to the console’s muting and solo/cue interrupt circuits (front panel switch defeatable). A CR ON switch turns the console’s control room outputs on and off. There are two such outputs; both are electronically balanced line level: one is post level control, the other pre (fixed). MODE Switch The mode switch affects both CR and HDPN outputs as follows: Left Mode (LT) – Left signal to both channels Right Mode (RT) – Right signal to both channels Mono Mode (MN) – Left plus right sum signal to both channels Stereo (ST) — “Normal” mode (MODE switch illuminated). Tally Ports The CR-1000 module outputs the console’s On-Air tally function. There are two ports: relay closure and opto-isolated. Both are con- trolled by the console’s mute/tally control lines (four; which one activates the CR tally port is determined by a PCB-mounted dipswitch). Metering Solo/External The console’s solo/external left/right meter pair is multi-func- tional. Under normal use, they will monitor the external line source selected at the VU/Oscillator module’s “External Meter Select” switches (see page 7-3; four external sources are available, brought in at the VO module’s rear panel upper DB-25 connector). Whenever CUE or SOLO is activated anywhere on the console, however, the meters automatically switch to the activated signal (a “solo/cue activated” LED below the external source switches lights when this happens).

page 5 – 4 TV1 / May 98 When solo/cue is de-activated (either by pressing the pertinent switch again, or by using the master solo/cue dropout panel switch) the meters return to the selected external signal. Since SOLO (AFL) and CUE (PFL) functions are normally programmed to interrupt control room and operator headphone monitor feeds, and since there can easily be over one hundred individual solo and cue switches scattered throughout an average console’s control surface, the SOLO/CUE MASTER DROPOUT switch (located directly below the VO-1000 module; see page 7-3) is extremely useful to quickly return the console to a “regular” operational state without having to hunt down the single (or multiple!) offending solo/cue switch(es) causing an interrupt. There are two sets of front panel calibration trimpots associated with the solo/ext VU meters. The first set calibrates the meter driver circuitry itself at the VO-1000 module (“Solo/Ext”— located at the top of the VO module faceplate). The second set (“Solo/Cue”) is located at the top of the control room monitor (CR-1000) module; these adjust the level of the solo/cue signal being fed to the VO-1000 module circuitry. Solo/Cue Logic Programming A number of PCB-mounted programming switches on the CR- 1000 module allow the console’s solo/cue interrupt system to be configured in different ways. The system is designed to allow the console operator to spot monitor any signal or module via PFL (Cue) or AFL (Solo) switching throughout the signal chain. Any time a SOLO or CUE switch is activated on the console, the CR-1000 module’s control room and headphone outputs are automatically interrupted and the selected signal replaces the monitor signal normally determined by the module’s MONITOR SOURCE SELECT switching. Whether or not these interrupts occur, and the manner in which they occur, is determined by the programming switches described in this section. HDPN/CR Interrupt Select PCB dipswitch “SW23” (see Technical Drawings CR-1000 sche- matic page 87 C-4, and PCB load sheet page 89 lower right) determines which signals (cue and/or solo) will interrupt the module’s CR and/or HDPN outputs. Cue Enable PCB dipswitch “SW25” (see Technical Drawings CR-1000 sche- matic page 87 C-4, and PCB load sheet page 89 lower right) determines which console logic signals (cue and/or solo) will enable the module’s CUE output. NOTE the level of the SOLO/CUE interrupt signal is determined by the solo/cue master ro- tary level control and not by the CR or HDPN level pots; thus, be careful when setting the solo/cue master level or you may be unpleas- antly surprised the first time you activate a solo/ cue switch. ! TV1 / Oct 98

page 5 – 5 TV1 / May 98 CR/HDPN Dim Option Normally a cue or solo signal will replace the CR-1000 module’s regular monitor output. However, it is also possible to DIM (attenuate) the regular output and overlay it with the full strength cue/solo signal. PCB dipswitch “SW24” (see Technical Drawings CR-1000 schematic page 87 B-4, and PCB load sheet page 89 lower right) can activate the DIM function for CR interrupt (dipswitch toggle #1) and/or HDPN interrupt (dipswitch toggle #2). If your console is equipped with optional front panel dim trims the amount of attenuation for the CR and HDPN dim functions may also be adjusted. CR/HDPN Mute The console’s four mute control lines can automatically turn off the module’s CR and/or HDPN outputs whenever a programmed input module channel ON switch is activated. PCB-mounted dipswitch “SW24” (see Technical Drawings CR-1000 schematic page 87 B-4, and PCB load sheet page 89 lower right) can activate this muting function for CR (dipswitch toggle #3) and/or HDPN (dipswitch toggle #4). WHICH of the console’s four mute control lines will activate the CR-1000 module’s muting functions is determined by PCB-mounted dipswitch “SW22” (see Technical Drawings CR-1000 schematic page 87 D-5, and PCB load sheet page 89 lower right). Cue Speaker Output Mode PCB-mounted slide switch “SW18” (see Technical Drawings CR-1000 schematic page 86 D-2, and PCB load sheet page 89 lower center) determines whether the module’s cue speaker output is stereo or mono (L+R sum). Headphone Output Options Headphone Amp Output Mode PCB-mounted slide switch “SW19” (see Technical Drawings CR-1000 schematic page 86 B-2, and PCB load sheet page 89 lower center) determines whether the module’s headphone amplifier output is stereo or mono (L+R sum). Headphone Line Output Pre/Post Select PCB-mounted slide switch “SW17” (see Technical Drawings CR-1000 schematic page 86 C-4, and PCB load sheet page 89 center) determines whether the module’s electronically balanced line level headphone output is pre or post headphone level control. TV1 / Oct 98

page 5 – 6 TV1 / May 98 Control Room “On-Air” Tally Port The CR-1000 module tally port is activated by the console’s mute control lines (see dipswitch “SW22”, preceding). Tally signals are outputted at the module’s DB-9 “TALLIES” connector, located at the top of the module’s rear panel. There are two types of control signals available: a) a simple relay closure with N.O., N.C. and tally com- mon pins (maximum current 50 milliamps at 24V), and b) opto-isolated tally+ and tally– control pins (used to power an external +5V tally light/LED; maximum current 50 milliamps).

page 6 – 2 TV1 / Oct 98 Studio Control Module General TV-1000 audio consoles can be equipped with one or more SC-1000 studio monitor modules. Each of these modules allows the console operator to send monitor versions of the TV-1000 console’s outputs to a separate studio. Source selection is determined by a set of monitor source select switches that match those available on the console’s control room monitor module. Each studio module has two outputs: a main electronically balanced line level STUDIO output, and a dedicated HEADPHONE output avail- able as line level or from a built-in headphone amp. Each module also features an on-air tally port and a talkback circuit. Input channel audio I/O (input/output) connections are made via two DB-25 multi-pin connectors (“A” upper; “B” lower) located on the back rear panel of the module. Tally logic and control signals are made through a DB-9 “TALLIES” connector directly above the rear panel’s two DB-25 audio connectors (see page 6-5). Please refer to the signal flow diagram on page 84 of the Technical Drawings in conjunction with the text of this chapter. Note the SC-1000 studio monitor module utilizes the same printed circuit boards as the CR-1000 module. Controls Studio VU Trims Two pairs of recessed, front panel trimpots used to calibrate optionally available Studio Monitor meters. Talkback Dim Trims Two pairs of recessed, front panel trimpots are used to set the level of the TB interrupt to the module’s headphone and studio outputs. Monitor Select These source select switches allow studio talent to monitor the console’s eight aux sends, eight submasters and four master outputs. Four additional external line inputs may also be accessed.

page 6 – 3 TV1 / Oct 98 Headphone Section The studio module’s headphone circuit follows the monitor source select switching. There are two headphone outputs: one electronically balanced line level out (programmable as either pre or post HDPN level control), and the other driven by a built-in amplifier (amplifier output may be stereo or L+R summed). Note the headphone outputs are normally subject to the console’s mute control circuits; however, this may be defeated by a front panel switch if desired. Studio Section Studio output is determined by the module’s monitor source select switching and is subject to the console’s muting and talkback interrupt circuits (muting is front panel switch defeatable). A studio talkback switch (TB) routes the console operator’s talkback microphone signal (see “Talkback” on page 7-3 of the VO-1000 Chapter) to the studio output. There are two studio output ports; both are electronically balanced line level: one is post level control, the other pre (fixed). MODE Switch The mode switch affects both STUDIO and HDPN outputs as follows: Left Mode (LT) – Left signal to both channels Right Mode (RT) – Right signal to both channels Mono Mode (MN) – Left plus right sum signal to both channels Stereo (ST) — “Normal” mode (MODE switch illuminated). Tally Ports The SC-1000 module includes a tally function. There are two ports: relay closure and opto-isolated. Both are controlled by the console’s mute/tally control lines (four; which one activates the studio tally port is determined by a PCB-mounted dipswitch). 1 2 3 4 1 2 3 4 5 6 7 8 S U B M A S T E R S M S T R S 1 2 3 4 E X T 1 2 3 4 5 6 7 8 A U X S E N D S L STUDIO R L STUDIO TB R 8 0 9 7 4 5 6 3 2 1 0 1 HDPN 8 0 9 7 4 5 6 3 2 1 0 1 STUDIO M O D E L T R T S T TB MONITOR SELECT M N MUTE MUTE D E F E A T D E F E A T L R HDPN V U T R IM IM T R IM D SC TV1 / Oct 98

page 6 – 4 TV1 / Oct 98 Studio Module Logic Programming HDPN Talkback Interrupt PCB dipswitch “SW25” (dipswitch toggle #4; see Technical Draw- ings CR-1000 schematic page 87 C-4, and PCB load sheet page 89 lower right) determines whether talkback will interrupt the studio HDPN outputs. STUDIO/HDPN Dim Normally the operator talkback signal will replace the SC-1000 module’s regular monitor output. However, it is also possible to DIM (attenuate) the regular output and overlay it with the full strength talkback signal. PCB dipswitch “SW24” (see Technical Drawings CR- 1000 schematic page 87 B-4, and PCB load sheet page 89 lower right) can activate the DIM function for STUDIO interrupt (dipswitch toggle #1) and/or HDPN interrupt (dipswitch toggle #2). If your console is equipped with optional front panel dim trims the amount of attenuation for the STUDIO and HDPN dim functions may also be adjusted. STUDIO/HDPN Mute The console’s four mute control lines can automatically turn off the module’s STUDIO and/or HDPN outputs whenever a programmed input module channel ON switch is activated. PCB-mounted dipswitch “SW24” (see Technical Drawings CR-1000 schematic page 87 B-4, and PCB load sheet page 89 lower right) can activate this muting function for STUDIO (dipswitch toggle #3) and/or HDPN (dipswitch toggle #4). WHICH of the console’s four mute control lines will activate the SC-1000 module’s muting functions is determined by PCB-mounted dipswitch “SW22” (see Technical Drawings CR-1000 schematic page 87 D-5, and PCB load sheet page 89 lower right). Headphone Amp Output Mode PCB-mounted slide switch “SW19” (see Technical Drawings CR-1000 schematic page 86 B-2, and PCB load sheet page 89 lower center) determines whether the module’s headphone amplifier output is stereo or mono (L+R sum). Headphone Line Output Pre/Post Select PCB-mounted slide switch “SW17” (see Technical Drawings CR- 1000 schematic page 86 C-4, and PCB load sheet page 89 center) determines whether the module’s electronically balanced line level headphone output is pre or post headphone level control.
