    PS Engineering to arrange for a replacement. Under no circumstances attempt to install a damaged unit in an aircraft. Equipment re- turned to PS Engineering for any other reason should be shipped in the original PS Engi- neering packaging, or other UPS approved packaging.

  • Page 9: Mounting Rack Installation

    Refer to FAA Advisory Circular 43.13-2A for more information. Failure to use correct techniques may result in improper operation, electrical noise or unit failure. Damage caused by improper installation will void the PS Engineering warranty. 2.5.1 Noise Due to the variety and the high power of radio equipment often found in today's general aviation aircraft, there is a potential for both radiated and conducted noise interference.

    Adding a high-performance audio control system, particularly in conjunction with high- performance active noise canceling headsets, cannot improve on older avionics that were designed for cabin-speaker use. PS Engineering makes no claim that the audio panel will provide a noise-free audio quality under all installation conditions, particularly with older avionics.

    PTT switches to be used. Modify external PTT as required (See Appendix A). Additional capability can be added to the PMA7000MS for observer or additional trans- mit stations. Contact PS Engineering for information 2.5.6 Transmit Interlock Some communications transceivers use a transmit-interlock system. To fully utilize the Split Mode feature, this function must be disabled.

    PS Engineering PMA7000M-S Series Audio Selector Panel and Intercom System Civil Air Patrol Version Installation and Operator’s Manual 2.5.12 PA Mute (J1, Pin 18) Pin 18 of J1 is TTL logic output that is pulled low during PTT operation. This serves as an input to external public address system to prevent feedback during transmissions.

    After wiring is complete, verify power is ONLY on pin 20 of the J1 (bottom connector) (dim power may also be at Pin D and F), and airframe ground on bottom connector pin Z. Failure to do so will cause serious internal damage and void PS Engineering's warranty. 2.10 Unit Installation To install the PMA7000M-S, gently slide the unit into the mounting rack until the hold- down screw is engaged.

  • Page 20: Split Mode

    Split mode, particularly on adjacent frequencies. PS Engineering makes no warranty about the suitability of Split Mode in all aircraft conditions. Note: Split Mode does not turn off other (Nav, ADF, etc.) selected audio to pilot. However, the copilot will only hear the selected communications receiver.

  • Page 21: Intercom

    Moving your head through a vent air stream may cause the IntelliVox®to open mo- mentarily. This is normal. For optimum microphone performance, PS Engineering, Inc. recommends installation of a Microphone Muff Kit from Oregon Aero (1-800-888-6910). This will not only optimize VOX performance, but will improve the overall clarity of all your communications.

  • Page 22: Volume Control

    All passenger headsets are connected in parallel. Therefore, if a monaural headset is plugged in to a PMA7000M-S Stereo installation, one channel will be shorted. Although no damage to the unit will occur, all passengers will lose one channel. PS Engineering modifies headsets to add stereo capability, using high-fidelity speakers. Contact factory for details.
