TDAP-611 Operating Instructions TiL 15RE553 Rev. B 1 1.1 INTRODUCTION This publication provides operating information on the TDAP-611 Audio Panel. The TDAP-611 is only available with Night Vision Goggle (NVG) optimized panel lighting. 1.2 DESCRIPTION The Technisonic Digital Audio Panel (TDAP) Audio Management System TDAP-611 is a panel mounted Digital Audio System that provides centralized control and management for all audio signals within the airframe for up to 7 distinct Users (Pilot, Co-pilot, and five passengers) with varying degrees of connectivity depending on their station. The TDAP-611 connects to all aircraft Transceivers (up to a maximum of 8 distinct Transceiver Inputs), Navigational Receivers (up to a maximum of 8 distinct Receiver Inputs), Externally Alerting Sirens, and User Headsets. The unit includes functionality allowing expansion to an external PA or Paging system; it also supports full Simulcast transmitting as well as Monitor Only functionality amongst all connected Transceivers. To reduce pilot workload and avoid operational problems, ACCESS/D™ systems have auto-RX switching when a transmitter is selected. The TDAP-611 has front panel selectable and adjustable VOX, LIVE, or KEYED intercom (ICS) functions. An EMERGENCY mode locking toggle provides "straight through" or “fail-passive” transmit and receive audio for the pilot or other user on a pre-set radio. In the NORMAL position (front panel LED is green), the pilot's audio is provided as selected by all of the panel controls and is part of the ICS system. Separate RX and ICS volume controls are provided on the panel along with an ICS VOX threshold control. 1.3 MODEL VARIATION There is no model variation. The TDAP-611 is only available with Night Vision Goggle (NVG) optimized panel lighting. SECTION 1: GENERAL DESCRIPTION

TDAP-611 Operating Instructions TiL 15RE553 Rev. B 3 1.5 SYSTEM LIMITATIONS A summary of the relevant system limitations is given below. 1.5.1 POWER LIMITATIONS With Standard Set-up, which consists of seven headsets connected, a power output of not less than 250 mW is delivered per headset (as represented by 150 ohms). Nominal microphone input: 250 mVrms; Nominal Communications/Navigational Input: 2.5 Vrms. 1.5.2 FREQUENCY RESPONSE LIMITATIONS In accordance with the provisions made in RTCA/DO-214 Sections 2.8.1 and 1.5.1, the communications transmit out and receiver channels (communications and navigational) possess an effective bandwidth of 300 Hz – 3000 Hz with a maximum amplitude variation of 3 dB within the frequency range. 1.5.3 CROSSTALK LIMITATIONS To ensure that the crosstalk specifications are in accordance with the applicable sections of DO-214, it is essential that 1) Manufacturer’s maximum microphone input voltage of -4.7 dBu must not be exceeded in order to avoid jeopardising input to microphone output crosstalk results, particularly at the low frequency end. 2) In the instance where only two access units are daisy chained via their ICS tie-lines, a resistor of not greater than 600 ohms must be maintained across the ICS tie-line in order to avoid jeopardising station to station crosstalk results in RX mode at the high frequency end. When multiple transceivers are selected for simulcast operation, they are bound together at the station output; thus, they are also bound together for other stations as well and defeat crosstalk measurements. All measurements are based on single transceiver (TX) selection. 1.5.4 TRANSMISSION PRIORITY Where Pilot and Co-pilot transmit simultaneously, the Pilot transmissions take precedence over those of the Co-pilot. Co-pilot transmissions in this case would be rendered inactive. 1.5.5 INDUCED SIGNAL SUSCEPTIBILITY, RF SUSCEPTIBILITY, AND RF EMISSION The wiring connections called out in Chapter 2 describe shield terminations for minimum ground loop noise. The test harnesses used for RTCA/DO-160 Sections 19, 20, and 21 – Induced Signal Susceptibility, RF Susceptibility, and Emission of RF Energy respectively – used shield terminations at both ends of the cable. Should RF susceptibility pose a problem in a particular installation, the installer may wish to try terminating shields at both ends of the cable. If this does not produce satisfactory results, then double shielding may be required.

TDAP-611 Operating Instructions TiL 15RE553 Rev. B 5 2.1 FRONT PANEL This section explains the operation of the TDAP-611 Audio Panel, and how to use the system in a typical aircraft environment. All normal user controls are on the front panel of the unit and are either variable rotating controls, or selectable pushbutton switches. The exact radio legends on the buttons of the TDAP-611 may vary from the illustration shown, due to the final legend inserted into the buttons that is installed for the specific aircraft installation. For a full view of the controls given, please see Figure 1. All rotary controls are illuminated for night flight. FIGURE 1: TDAP-611 Front Panel Operators Switches and Control The top row of variable controls sets the level of the incoming RX or RECEIVER audio from the associated Communications Transceiver radio as listed on the button immediately below the knob (COM1, COM2, etc. through to COM8). The volume controls also have a push-on / pull-off functionality that selects which of the incoming receiver audio will be sent to the crew headsets. The volume control and the switch function independently of each other. Pull out the switch to be able to monitor the receiver audio and adjust the volume to the desired level. The middle row of pushbuttons selects the transceiver (or COM radio) to be used when transmitting. When a COM transceiver has been selected, its associated indicator will be illuminated and any incoming RX or RECEIVER audio will be sent to the crew headsets. This function is often referred to as Auto-RX select. Press the button again to deselect the COM transceiver. Any combination of RX sources may be selected at one time for system monitoring purposes. Multiple TX destinations may also be selected by pressing in two or more buttons simultaneously to set up simulcast operation. Pressing any TX button in automatically resets any previous selection, but RX selections are independent push on / push off switches. The left-most pushbuttons are normally for AM COM transceivers; the remaining pushbuttons are for tactical radios. The dual-concentric knobs at the right side of the unit adjust ICS VOLUME (intercom, inner knob) and RX VOLUME (outer knob). SECTION 2: OPERATING INSTRUCTIONS

TDAP-611 Operating Instructions TiL 15RE553 Rev. B 6 Selecting the PA pushbutton deselects any active COM transceiver; however, the COM transceiver set-up is stored in memory, so deselecting the PA pushbutton will restore your original set-up. When the PA is selected, all transmit audio will be delivered to the PA system. The bottom row of variable controls sets the level of the incoming RX (receiver) audio (or MUSIC, for the knob furthest to the right) from the associated Navigation Receivers or connected music player. The volume controls also have a push-on / pull-off functionality that selects which of the incoming receiver audio will be sent to the crew headsets. The volume control and the switch function independently of each other. Pull out the switch to be able to monitor the receiver audio and adjust the volume for the desired level. The knob at the far right adjusts the VOX LEVEL of the INTERCOM as well as its exact mode of operation (KEY, VOX, or LIVE). The VOX control also has a push-on / pull-off functionality that controls the ICS Mode of the audio controller (all connected or CREW/PAX ISOLATION). An indicator beside the knob shows which mode the audio controller is in. 2.2 COM SELECTION AND VOLUME CONTROLS To select a COM transceiver to transmit on, press the associated COM SELECT pushbutton (middle row of the front panel). When selected, the associated indicator will be illuminated. All RECEIVER audio associated with that COM transceiver will be heard by the crew. When a crew member transmits, only his/her activated microphone audio will be sent to the associated COM transceiver. The pilot has transmit priority over the co-pilot. To transmit on multiple radios at the same time (Simulcast), press multiple pushbuttons at the same time. All activated COM transceiver indicators will illuminate. To deselect a COM transceiver, press the associated pushbutton again. The associated indicator will no longer be illuminated. To monitor the RECEIVER audio of a specific COM transceiver without selecting it for transmit, pull the associated RX LEVEL volume knob (top row of the front panel) out. Now, all receiver audio associated with that COM transceiver will be heard by the crew. The RX LEVEL volume control knob (top row) controls the volume level of the specific COM transceiver it is associated with in order to balance the levels coming from various radio sources. The MAIN RX VOLUME control (outer control of the dual concentric knob on the bottom left of the front panel) controls the volume level of all COM transceivers at once. 2.3 NAV SELECTION AND VOLUME CONTROLS To monitor the RECEIVER audio of a specific NAV receiver, pull the associated RX LEVEL volume knob (bottom row of the front panel) out; now, all receiver audio associated with that NAV transceiver will be heard by the crew. The RX LEVEL volume control knob (bottom row) controls the volume level of the specific NAV Receiver(s) it is associated with in order to balance the levels coming from various radio sources. The MAIN RX VOLUME control (outer control of the dual concentric knob on the bottom left of the front panel) controls the volume level of all NAV transceivers at once (as well as all COM transceivers).

TDAP-611 Operating Instructions TiL 15RE553 Rev. B 7 2.4 INTERCOM (ICS) SELECTION AND VOLUME CONTROLS The ICS VOX knob selects how the intercom system is activated. In the VOX (Voice Activated) mode, the audio produced by any of the microphones will break the squelch of the intercom and the audio will be routed through the system. The threshold audio level required to break the squelch is adjusted by this knob. Turning the knob more counter-clockwise makes the system more sensitive to incoming mic audio. A fully counter-clockwise setting on the knob will leave the intercom on at all times giving LIVE or HOT MIC operation. When set fully clockwise, the intercom is in the KEYED mode and will only produce audio when the intercom PTT line is keyed. While the co-pilot, pilot, and passengers have individual mic VOX gates (3 in total), they are controlled from a common front panel control. Individual gating reduces the amount of unwanted noise when the intercom is triggered and makes intercom communication more intelligible as a result. The passengers may have their VOX threshold offset by an internal adjustment (PAX VOX) to accommodate differing headset types or ambient noise conditions. With only a single TDAP-611 Audio Panel, best operation of all ICS functions is obtained when the microphones are all of the same type (or have very similar characteristics). Headsets with significantly different microphones or earpiece efficiencies make it difficult to achieve satisfactory control adjustments for all users, unless they also have individual level controls. Good quality headsets (such as David Clark, Telex, or Bose), with noise reducing, amplified dynamic microphones and individual headset volume controls, give the most effective and user-adjustable performance and minimal system difficulties. The use of “clone” headsets that visually resemble these higher quality units, but have much poorer electrical and acoustic performance, is strongly discouraged, as the entire system operation will suffer. This is especially true under high noise conditions. The ICS LEVEL knob controls the intercom volume level for all users. Fully clockwise is the maximum volume level and fully counter-clockwise is the minimum. The TDAP-611 contains two Intercom systems, one that services the Pilot and Co-pilot and one that services the passengers. If the ICS VOX knob is pushed in, the two Intercom systems are interconnected and the crew members can communicate with the passengers through the intercom system. If the ICS VOX knob is pulled out and the indicator is illuminated, the Crew and Passenger intercom systems are isolated from one another on completely separate intercom systems and communication between the two groups through the intercom system is not possible. 2.5 PA CONTROLS To select the PA to transmit on, press the PA pushbutton. When selected, the associated indicator will be illuminated. Selecting the PA pushbutton deselects any active COM transceiver; however, the COM transceiver set-up is stored in memory, so deselecting the PA pushbutton will restore the original set-up. When the PA is selected, all transmit audio will be delivered to the PA system. If the PA is selected for longer than 30 seconds, the PA select pushbutton indicator will begin to flash to warn users they will be talking on the PA system and not a radio. This is a safety feature to prevent accidental transmission over the PA system, which can have significant repercussions.

TDAP-611 Operating Instructions TiL 15RE553 Rev. B 8 2.6 EMERGENCY SWITCH OPERATION The operation of the TDAP-611 control can be changed from NORMAL to EMERGENCY operation in two different ways. First, if DC power fails to the unit, the internal auto-emergency function is enabled; this transfers the unit to a passive emergency mode to enable critical communication to continue for the pilot. Second, the EMER/NORM can be placed in the EMER position (up) and will force this transfer. In both cases, the backlighting will be extinguished and the panel will go black. In either case, the Pilot (or primary user of the control) is connected directly to the COM1 radio. Boom Mic Transmit operates normally, as does receive, but the headset power level is reduced to the passive (un- amplified) radio level. 2.7 DIRECT AUDIO CONNECTIONS The TDAP-611 has three different un-switched, direct audio inputs. One is routed directly to the Pilot’s headset output via a resistive pad. This is used when an existing airframe threat alerting system must be tied directly to the pilot’s headset. This function is active when in either the normal or emergency mode, and its volume is a function of the external generating source and the headset impedance. This should be tested (if implemented) to ensure adequate headset level is possible in the specific application. Excessive loading back through this connection may reduce headset volume or adversely affect the pilot’s headset, so please be certain this function is correctly implemented. The other direct inputs are un-switched only and are mixed with the regular RX audio bus. They will be partially muted during TX operation and must be used carefully to ensure correct system operation. This signal should NOT be wired in the harness if not needed, as it will serve merely as a source of noise if left stowed in the aircraft wiring. It cannot be switched off and will be lost during emergency operation. 2.8 TONE ALERTING Alerting tones are activated by a ground trigger at the corresponding input pin and play once the alert line is triggered. The #3 (Decision Height) alert is timed and the #2 alert (Low Rotor) over- rides tone #1 (Engine Failure). Always confirm alerting is working correctly and is at an acceptable level before completing any installation. ALERT FUNCTION CORRESPONDING TONE INPUT FORMAT INPUT PIN Engine Failure 1 (Steady tone) Repeat continuously. Pin 15, Alert 1 Low Rotor RPM 2 (Pulsing tone) Repeat continuously. Over-rides tone 1. Pin 14, Alert 2 Decision Height 3 (Two-tone) Timed, 2-3 sec. Typical. Pin 13, Alert 3

TDAP-611 Operating Instructions TiL 15RE553 Rev. B 9 2.9 SPEAKER AUDIO The TDAP-611 has a speaker channel that may be used as a “music only” feed for a passenger cabin area, if desired. This is an optional connection and does not have to be used. The speaker level is driven by the front panel MUSIC control and by an optionally attached external music volume control. 2.10 CHANGING RADIO LEGENDS The legends on the TDAP-611 front panel pushbuttons can all be easily changed in the field to suit special requirements. The legend insert is adhesive and can be removed by lifting a corner free with a sharp X-acto knife blade and then gently pulling the entire Lexan strip free. Remove the backing from a new legend strip (with the desired legends), line it up evenly, and press it into place on the overlay recess. The adhesive will cure fully in 48 hours. Be sure any bubbles are pressed out, and that all edges are firmly attached with no exposed lighted edges.
