Figure 1 DB-25 Audio Connections SF-16M units may be linked together to create systems up to 32 inputs x 64 outputs (see p. 13 for hookup details). The DB-25 ports streamline this type of expanstion, and also serve as a connection from Audio Authority matrix systems. 1. Source audio link between SF-16M units: When multiple SF-16M units are linked together, the DB-25 audio input receives source audio from the DB-25 audio loop output of the previous SF-16M. The source audio originates from the RCA audio inputs or the DB-25 audio input of the first SF-16M chassis. (See figure 2 below). 2. Direct input from an Audio Authority audio matrix: For installations where the SF-16M is serving as an amplifier for Audio Authority audio matrix switchers such as the ADX-0808/ADX-1616 and the HLX 2278 audio output card (See Illustration below). In this scenario, the SF-16M receives all audio content from the ADX or HLX and passes the audio through to the amplified outputs. The HLX or ADX provides all of the matrix switching (See figure 3 below). SF-16M CONNECTIONS - Audio Inputs RCA Line Inputs The SF-16M includes 16 RCA audio inputs that can be configured as mono, stereo or a combination of both mono and stereo. Figure 1 shown below provides examples of all configurations. NOTE: It is important that all physical input configurations are entered into the SF-16M programming, using the PC configuration software or the front panel system menu. 3 4 5 6 7 8 9 10 11 12 13 14 15 16 SPEAKER OUTPUTS (CLASS 2 WIRING) ETHERNET USB RS-232 IN RS-232 OUT LINK SPEED MAIN IR IN MAIN IR OUT UNIT ID DB25 AUDIO INPUT 5V - 24V AC / DC AUDIO LOOP OUTPUT LINE INPUTS BUS IN OUT SYSTEM TRIGGER 100- Rep wit Remp avec Fu Set voltage selector and install correct fuses according to local power supply.

FlexPort Cat 5 Audio Inputs The SF-16M includes two FlexPort Cat 5 inputs that accept a variety of pro and consumer audio sources via optional FlexPort audio modules. See Appendix A for a detailed overview of all FlexPort modules and system configuration. FlexPort module options include: FPM-B Balanced line/mic with phantom power FPM-X XLR/ 1/4” TRS with phantom power FPM-D Digital optical/coax FPM-U Analog RCA Understanding the FlexPort Audio Bus Each SF-16M FlexPort input supports: • Two channels of audio - input can be either stereo or two mono channels (allows two mono inputs per FlexPort bus) • RS-485 data pathway - provides 2-way communication between the SF-16M and all connected FlexPort modules • 18V power - provides power for two FlexPort modules on a single bus Daisy Chain FlexPort Modules For Two Mono Inputs Per Bus All FlexPort audio modules feature a FlexPort Bus In and Out, so any two modules may be daisy chained together for a two mono source setup. In daisy chain configurations, it is required to assign one module as “Mono 1” and the other module as “Mono 2” using the dipswitches located on the back of the FlexPort modules. See Appendix A for more information. Figure 4 below illustrates a daisy chain configuration.

In many cases only one speaker is connected per amplifier output, so any single speaker with a 4 - 8 Ohm impedance rating is acceptable for use with the SF-16M. Two 8 ohm speakers can be connected in parallel onto a single SF-16M amplifier output without sacrificing performance (Figure 7). Do not connect multiple 6 ohm or 4 ohm speakers to one SF-16M output, and do not connect multiple speakers wired in series. Ferrite Beads If System Trigger or Override terminals are used, attach a ferrite bead around the wires near the terminal. Apply a separate ferrite bead to override and system trigger wires. Changing the Power Fuse Before changing the fuse, find and correct the excessive impedance load or wiring short that caused the fuse failure. The fuse compartment contains two extra fuses that can be used to replace blown fuses in the field. Access the replacement fuses by sliding out a compartment behind each fuse, as shown in Figure 7. • Remove the power cord • Use a flat head screwdriver to remove the fuse cover • Inspect both fuses to determine which one is blown. • Replace the blown fuse with a new fuse CAREFULLY PRY WITH A SMALL SCREWDRIVER FUSE COVER SPARE FUSE ACTIVE FUSES

SF-16M CONNECTIONS - Control The SF-16M provides four methods of system control: 1. Front panel menu (See page 15 for detailed information) 2. DB-9 RS-232 port using a 3rd party serial controller 3. RJ-45 Ethernet port using a 3rd party ethernet/telnet controller 4. 3.5mm IR port using a 3rd party IR controller RS-232 Port The DB-9 “Serial In” port of the SF-16M can be connected to virtually any 3rd party RS-232 controller using a straight- thru serial cable.

The System Trigger input on the SF-16M allows equipment such as AV receivers or power managment devices to put the SF-16M in standby when not in use, thereby greatly conserving energy usage. To enable the System Trigger: 1. Make system trigger connections as illustrated in Figure 13. 2. Power the SF-16M, then apply power to the triggering device. 3. Using the front panel menu (see page 17) or the PC configurator, enable “System Trigger” Figure 12 NOTE: In order for Audio Override to function, all settings must be programmed using the PC configuration software, available for download on the SF-16M product page. SF-16M CONNECTIONS - System Trigger (5V-24V AC/DC) SF-16M CONNECTIONS - Audio Override (Contact Closure) The SF-16M provides two “Audio Override” contact closure inputs, which allow pushbuttons, partition wall contacts, and other contact sensors to trigger the system. Audio override provides a convenient method of temporarily switching to an alternate audio input when a sensor is triggered. A practical example of this feature is a conference hall with movable partition walls (Figure 12). The speakers in the room normally play background music from a satellite radio receiver. A pushbutton triggers Override 1 which is programmed to toggle speaker outputs for both rooms between background music and the Microphone 1 input. When the partition closes to create individual rooms, a partition wall contact closure (Override 2 in the example) triggers the SF-16M to switch the speakers in Room B to microphone 2. When the partition wall opens, the SF-16M returns to its default audio input. 1 2 3 4 5 6 7 8 9 10 11 SPEAKER OUTPUTS (CLASS 2 WIRING) ETHERNET USB LINK SPEED UNIT ID DB25 AUDIO INPUT CONTACT CLOSURE 5V - 24V AC / DC AUDIO LOOP OUTPUT LINE INPUTS BUS FlexPort 1 OUT IN 1 2 IN OUT SYSTEM TRIGGER AUDIO OVERRIDE 1 3 5 7 9 A B C D 2 4 6 8 10 L R Audio Authority® Corp. • 2048 Mercer Rd.

SF-16M CONNECTIONS - Connecting Multiple SF-16M Chassis Up to four SF-16M units can be linked to function as a 64 output system. In Figure 14, the maximum number of input channels is 20; 16 inputs via RCA or DB-25, and four shared Flexport channels. Units are linked using the loop out con- nections for FlexPort Audio, DB-25 Audio, IR, Serial and System Trigger inputs (see p. 12). Set the Unit ID as shown, incrementing from top to bottom. All SF-16M units can share the Unit 1 FlexPort inputs, as shown, or each unit can have independent FlexPort inputs, increasing the total number of inputs to 32 (four FlexPort channels per SF-16 unit). 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 SPEAKER OUTPUTS (CLASS 2 WIRING) ETHERNET USB RS-232 IN RS-232 OUT LINK SPEED 701-13303B MAIN IR IN MAIN IR OUT UNIT ID DB25 AUDIO INPUT CONTACT CLOSURE 5V - 24V AC / DC AUDIO LOOP OUTPUT LINE INPUTS BUS FlexPort 1 OUT IN 1 2 IN OUT SYSTEM TRIGGER AUDIO OVERRIDE 100-120V~ 50-60 Hz 1125W Replace Fuses Only with T 10A, 250V Remplacer Uniquement avec Fusible T 10A, 250V Set voltage selector and install correct fuses according to local power supply.

CONFIGURATION Basic configuration of the SF-16M can be achieved using the front panel controls. It is possible to configure all settings on the SF-16M via telnet/serial commands with a program such as hyperterminal on your PC (page 18). The recommended method to perform advanced setup tasks is to use the SF-16M PC configuration software, available for download on the SF-16M product page at audioauthority.com. In addition to being more efficient, project files can be saved to your PC for backup and future modification. Detailed instructions for SF-16M setup using the PC configuration software are included with the software download. Advanced Configuration The following settings can be configured using Ethernet/serial commands or the PC setup utility (not front panel controls). 1. Output Groups - Group multiple outputs together to share source selection, volume up/down, mute on/off, and power on/off commands. Groups are ideal for making large areas act like a single audio zone or for grouping outputs with hi- pass and low-pass filters (sub/sat combinations) so that they respond together. Group specific serial and IR commands are available for source selection, volume up/down, mute on/off and power on/off. Up to 10 groups can be stored per SF- 16M. Group settings include group naming and output members. 2. Audio Override - The purpose of audio override is to provide a convenient method of temporarily switching a pre- defined group of outputs to a specific input. Once the audio override is completed the outputs effected by the override return to their previous input and volume levels. Typical examples of audio override include paging, doorbell tones and local source selection for in-room sources such as iPods and audio mixers. Audio override can be triggered by two contact closure inputs on the back of the SF-16M, as well as specific serial and IR commands. Up to 10 audio override configurations can be set up per SF-16M. Audio override settings include input assignment, output members, output levels, override priority and momentary or toggle mode for the audio override contact closures. 3. Sound Scenes - A sound scene is a system-wide snap shot of all volume levels and input assignments. Scenes allow the end-user to recall previously captured system settings with a single button press. Up to 10 sound scenes can be saved and recalled per SF-16M. Scenes can also be saved and recalled across multiple SF-16M’s linked together, however each individual SF-16M has a maximum of 10 unit or “global” scenes. Scene settings include scene naming, input selection, output levels, mute status and an “Ignore” option which allows any output to always ignore a scene preset. 4. EQ Filters - Up to seven EQ filters can be applied per SF-16M output, including hi-pass/low-pass, hi-shelf/low-shelf or seven-band parametric EQ. Parametric EQ can be used in combination with the other EQ filters. 5. Input/Output Naming 6. Network/IP Configuration

OPERATION Front Panel Description The front panel is operated by using three touch sensitive keys: Menu A , Back B , Dim C and a Multi-Function Knob D . Multi-Function Knob Operation: Used to navigate through all menu items, the multi-function knob can scroll (clockwise or counterclockwise) and select or de-select (press in). The open arrow  symbol is displayed when scrolling through menu items. Once an item has been selected (by pressing in the knob), the arrow will fill in . Next, turn the knob to adjust the value. Press in the knob again to de-select the menu item and scroll to the next item that needs to be adjusted. Menu Button > Menu Screen A Menu options: Output Settings, Input Settings, Override, Scene Presets, Groups, Front/Back Panel, Network, Firmware and Factory Defaults. The menu button also toggles the display between the main menu and output meters. Back Button B Press to return to a previous screen. Pressing the back button repeatedly eventually returns to the main menu. Dim Button C This button toggles through four brightness levels for the VFD and keyboard LED indicators. After a set period of time (adjustable using the front panel or the SF-16M PC configurator), the VFD enters a screen saver mode (dark). The power and button LEDs remain on at the defined level to show that the unit is receiving power. Any key press or knob adjustment causes the VFD to return to the last selected brightness level. Front Panel Menu Options Output Settings > Quick Access The Output Quick Access screen provides a “snap-shot” of key settings and the ability to adjust parameters for each setting. To begin, select the output you wish to view. Turn the knob and push to adjust any parameter. Output settings and descriptions are listed below: • Output Number/Name: A Lists the current output that is being viewed or adjusted. In this case, “Billiards” is a stereo output comprised of outputs 9 and 10. • Volume: B This line shows volume level, or other status messages: 1. Volume - The output level, a range from -80 up to 0 dB attenuation. Adjustable by a discrete value or using a volume up or down command. 1 dB increments in the -40 to 0 dB range, and 2 dB increments in the -80 to -40 range. 2. Standby - The SF-16M is in a power saving mode, which is triggered by issuing a standby command or using the back panel trigger. Affects all outputs. 3. Shutdown - Shutdown means the output cannot come on because of a short on the output, overheating of the output (impedance too low), or hardware failure. 4. Overtemp - The output is off due to too high a temperature of output chips. This can be caused by a speaker impedance that is too low or inadequate ventilation. 5. Poweroff - Power off mode (similar to mute) is set by the user. When power is turned on the output volume level is set to the previous level, within the maximum turn on and minimum turn on levels. 6. Muted - The output is muted, which silences the output temporarily. Unmute restores previous volume levels. 7. Automute - No input signals are detected for any of the 8 outputs in the output bank. Output banks 1-8 and 9-16 are separate, so if no audio is present on selected inputs to an output bank, the outputs automute.

Follow on-screen instructions and/or the text file instructions included with online firmware updates. Factory Defaults Use to restore all SF-16M settings to factory default. Follow on-screen instructions. Choosing a Control Interface The chart below provides an overview of the different range of capabilities when using each control method. For more detailed instructions on the various control methods available, please refer to these sections: • Controling the SF-16M through RS-232, see page 18 • Controling the SF-16M through Ethernet, see page 18 • Controling the SF-16M through IR, see page 19 • Controling the SF-16M with the Front Panel, see page 15

USING SERIAL AND ETHERNET (TELNET) Follow the instructions for your Control4, RTI, URC, or other controller using the serial settings below, and/or Ethernet settings accessible via the SF-16M front panel menu. Serial commands, available at our website on the SF-16M product page, are used for telnet or serial control. The internal SF-16M telnet server allows two clients to be connected at one time. Each client connection has a time out of 15 minutes; if a client crashes and does not close the connection properly (sending an EOF command) that connection remains busy until it times out. Using the RS-232 Port System controllers and PCs send all setup and control commands as well as receive feedback via the RS-232 serial port. • Important: If a PC is connected directly to the SF-16M RS-232 port, use a standard serial cable. • Communication Settings: baud rate is 9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control. • See the table and diagram below for the SF-16M serial port pinout. Using a PC via Ethernet Connect a computer directly to the SF-16M Ethernet port using a crossover cable, or alternatively use a standard Ethernet hub or switch and a standard patch cable. Once connected to a computer or network, the SF-16M by default attempts to obtain an IP address automatically using DHCP. To use static settings, see the detailed instructions on page 19. There are two LED indicators located next to the Ethernet port on the rear panel that will help in identifying connection issues: • Link - The Link LED is steadily lit if a connection is detected and flashes when activity is present. • Speed - The Speed LED is off for 10 base T, and on for 100 base T. DHCP DHCP is enabled on the SF-16M by default. If DHCP is enabled on your network, simply connecting the SF-16M to the network with an existing DHCP server enables it to obtain all necessary information. Static Addressing Connected Directly to a PC Assign an IP address to the SF-16M which will not conflict with the PC. • Windows 7: Control Panel -> Network and Sharing Center > Change adapter settings > Local Area Connection (or wi-fi adapter) > Details • Windows XP: control panel > network > local connection properties Change the TCP/IP protocol properties, and set the IP address, gateway, and subnet mask, if they are not already set. 5 4 3 2 1 9 8 7 6 GND RX TX Transfer Rate 9600 bps Data Bits 8 Parity None Stop Bits 1 Flow Control None or Off Character type ASCII Connector DB-9 Electrical Rating Pins 2 and 3, ±15 VDC Pin out Pin 2, Tx (Standard cable) Pin 3, Rx Pin 5, Ground Shell, Ground SF-16M screen image showing Network Settings with DHCP set to ON, with no link established. 1 2 3 4 5 6 ETHERNET LINK SPEED UNIT ID DB25 AUD CONTACT CLOSURE 5V - 24V AC / DC AUDIO LOO FlexPort 1 OUT IN 1 2 IN OUT SYSTEM TRIGGER AUDIO OVERRIDE FlexPort 2 OUT IN STEREO ZONE 1 STEREO ZONE 2 STEREO ZONE 3 DB-9 Connector on SF-16M rear panel Network Jack on SF‑16M rear panel

This can be arbitrarily done on a direct connection, but a good choice for the settings would be IP address of 192.168.0.1, subnet mask of 255.255.255.0, and an empty default gateway. Once these values have been set, use serial commands to set the network settings of the SF-16M in a similar manner, but use a different IP address than that of the computer (for example, 192.168.0.2). Static Addressing on a Network The SF-16M must be set to the same settings as the PC except for the IP address, which must be one available on the network. To determine this in Windows, use the DOS prompt (Start->Run->cmd) commands ipconfig and ping. Ipconfig will list the PC’s settings, and ping will allow you to test addresses to make sure that nothing else on the network has that address. Enlist the help of a network administrator if you are unfamiliar with setting up a network connection. Once a connection is established, a telnet program such as Hyper Terminal, Teraterm, PuTTY etc, must be used to connect to the device. Enter the IP address of the SF-16M and leave the default port (23) to connect. Once connected, standard serial commands can be issued in an identical manner to serial control. Using an IR Control System The SF-16M uses a two wire IR circuit. It is imperative that the correct polarity be maintained when connecting third party IR equipment. The 3.5MM pinout is shown in the illustration below. Connect the IR signal from your IR controller directly to the main IR input port on the rear panel. Alternatively, adhere an IR emitter from your infrared system onto the SF-16M front panel receiver. If the SF-16M IR codes are available from your remote control company, download and/or activate those files. A CCF file containing the latest codes can be downloaded from our website on the SF-16M product page. Tips for Using Infrared Control • If you are using standard hand-held IR remote controls, ensure correct operation by avoiding sources of light pollution such as Plasma and LCD TVs, direct sunlight, fluorescent light, etc. Experiment with the physical placement of the IR receiver to avoid interference. • If a source of interference cannot be eliminated or avoided, use IR receivers that block that type of interference, such as Plasma-proof or LCD-proof receivers.

Appendix A: FlexPort Audio Modules FlexPort audio modules provide up to four additional audio inputs (2 per FlexPort input) to each SF-16M. FlexPort mod- ules connect via Cat 5 cable to the SF-16M and accept a wide variety of pro and consumer audio sources. All FlexPort modules can be located up to 500 feet from the SF-16M and include mounting points for either surface or in-wall mounting in an “open ended” single gang bracket such as Arlington model LV1 or Carlon model SC100RR.

OFF SWITCH Appendix B: Firmware Update Procedure The latest version of firmware is available from our website on the SF-16M product page 1. Copy the latest firmware file onto a USB drive. 2. Insert the drive in the USB port on the rear panel of the SF-16M. 3. Press the menu key and navigate to the firmware update menu item. 4. Follow the prompts and select the firmware file. 5. After a short delay the SF-16M reboots and performs the firmware update. 6. Once the update has finished, the SF-16M reboots and resumes operation with the new firmware version. Appendix C: SF-16M Rack Mounting The SF-16M is designed so that it may be installed either on a shelf or in a standard 19-inch equipment rack. If rack mounting, remove the feet and the cover screws adjacent to the front panel of the unit. Reuse the cover screws to mount the rack adapters supplied with the SF-16M. Be sure to place a spacer under the adapters at every screw location. Secure the SF-16M to the rails of the equipment rack with the screws supplied, and use appropriate chassis supports, such as Middle Atlantic CSA Series. FlexPort Module “Override” Button The purpose of the front panel override button is to switch designated SF-16M outputs to a FPM input. A typical example is an audio mixer, connected to a FPM-X in a conference room. When the override button is pressed, designated outputs will switch over to the audio mixer for the duration of the override. When the override button is pressed again, all effected outputs will switch back to the input source prior to override. Audio override is based on two key settings: 1. FPM dipswitch settings, previously configured above. 2. SF-16M audio override settings, programmed using the SF-16M PC configuration software (see page 14 or view the PC configuration software manual for more information on audio override settings). Audio Override with “Mix” Option Enabled In some cases it may be desired to mix two FPM module inputs together upon audio override. An example would be a classroom where both a microphone and an audio presentation need to be heard simultaneously. To acheive this function, first daisy chain two FPM modules and wire back to the SF-16M. Set one FPM as “Mono 1”, and set the other as “Mono 2”. Both FPM’s must have the “Mix” dipswitch set to On.
