    The unit is designed for outstanding ergonomics and visual- ly defined mode annunciation and selection. The PMA8000D is specifically designed to be used in a dual audio panel environment; where the pilot and copilot positions have independent control over the radio au- dio control.

  • Page 5: Approval Basis

    A voice activated (VOX) intercom is included in the PMA8000D. This system has PS Engineering’s patent- ed IntelliVox® circuitry that eliminates manual adjustments. The intercom system incorporates pilot isolate, all and crew modes, two independent stereo music inputs with "SoftMute™".

    There must be at least 13.8 VDC present at the connector, J2 pins 8 & 9, of the PMA8000D for the power supply to work in its designed regulation. Otherwise, it can- not adequately attenuate power line noise.

  • Page 11: Power

    King Radio KX170-series, require a resistive load to prevent damage if their speaker amplifier is not used. Connect the speaker output from the unit to the COM 2 Speaker load input on the PMA8000D (J1 27 WRT 28). The speaker load is 16, 3W. Only one speaker per load is available in the PMA8000D.

  • Page 12: Unswitched Inputs

    2.4.6 Unswitched inputs PMA8000D, J1, pins 31, 29 and J2 pin 15 are unswitched, unmuted (by transmitter keying), inputs # 1, 3 and 4, respectively. These inputs are presented to the pilot audio panel and copilot audio panel regardless of the audio configuration, and will always mute the entertainment inputs.

  • Page 13: Public Address Mode

    Public Address Mode By pressing the Mute and SPR pushbuttons at the same time, the PMA8000D will be placed into public address (PA) mode. In this mode, the pilot will be talking over the cockpit speaker when he presses his PTT switch.

    This switch can be located anywhere in cockpit convenient to the pilot's reach. The NO switch should be connected to pin 22 of J2 of the PMA8000D, and ground. When installed, this button will act as in § 3.13.

  • Page 18: Marker Beacon Installation

    Marker Sensitivity switch (J2 Pin 13) The PMA8000D defaults to LOW marker sensitivity of 1000µVolts. If High marker beacon sensitivity is desired, J2 Pin 13 can be connected to ground (or J2 pin 14), through a switch, to set the marker beacon threshold sensitivity to 200 µVolts.

    It is probable that radio interference will occur in the split mode when the frequencies of the two air- craft radios are adjacent, and/or the antennas are physically close together. PS Engineering makes no expressed or implied warranties regarding the suitability of the PMA8000D in Split Mode.

    2.12 Operational Checkout 2.12.1 Required Test Equipment In order to return an aircraft to service after installation of the PMA8000D, the installer must have access to a Marker Beacon signal generator: IFR NAV401L, NAV402AP, IFR4000 TIC T-30D, T-36C Equivalent test equipment is acceptable as long as the testing requirements can be met.

  • Page 23: Marker Checkout

    Connect the marker antenna and verify proper operation. 2.12.4 Bluetooth Telephone Checkout Verify that the PMA8000D will “pair” with a Bluetooth device, and interface with cellular phone and Music source. See section 3.12 for more information. Verify that the pilot headset is connected to the cellular tele- phone system (if installed).

  • Page 26: Audio Selector (4)

    Stuck Microphone Protection (For units with serial number BD1023 and above) The PMA8000D will sense if the pilot or copilot radio PTT remains keyed for more than 32 seconds. When a stuck mic is detected, the key input is ignored, and the other crewmember can transmit normally. If the stuck becomes ungrounded, normal operation is restored.

  • Page 27: Cell Phone Sidetone

    The pilot’s panel does NOT have the capability for cell phone sidetone. As shipped, the copilots PMA8000D does provide cellular telephone sidetone (the user’s voice fed back to the headset). Some cell phones provide sidetone. In PMA8000D audio panels, Telephone sidetone can be disabled by pressing the COM 3 and ADF buttons for more than one second.

    Therefore, it may not recognize speech and clip syllables in a quiet cabin, such as in the hangar, or without the engine running. This is normal. For optimum microphone performance, PS Engineering 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.

NOTE The front jack is no substitute for the certified installation of alerts such as the GPS waypoint or autopilot tones.

  • Page 33: Music 1 Volume

    In general, we recommend adjusting the entertainment volume at the sources, and only using this as a master gain control. However, the Music 1 PMA8000D input can be adjusted from the front panel, if desired, by pressing the combinations of keys listed.

  • Page 34: Smart Function Keys (Sfk)

    These functions are non-essential and non-required and as such are only an accessory capability. They don’t affect the audio panel’s primary function as a selector panel, aircraft intercom, or marker beacon receiver. You can’t do anything with these buttons to prevent the PMA8000D from doing its main job.
