    Option 2 No silver trim around the bezel Opt. 2 Where the functions are identical to all units, it will be referred to herein as a PMA6000. Otherwise, the applicable units will be specified. EQUIPMENT DESCRIPTION The PMA6000-series is a state of the art audio isolation amplifier and audio selector that contains a voice activated (VOX) intercom system.

  • Page 8: Section Ii -Installation

    If the PMA6000/M-S is installed in a 27.5 VDC aircraft system, a 15 Ω, 15 Watt dropping resistor (p/n 701-015-1501) should be installed. Failure to do so will generate unnecessary heat inside the unit and may void PS Engineering's warranty.

  • Page 9: Mounting Requirements

    There must be at least 13.0 VDC present at the bottom connector, pin 20, of the PMA6000 for the power supply to work in its designed regulation. Otherwise, it cannot adequately attenuate power line noise. Shielding can reduce or prevent radiated noise (i.e., beacon, electric gyros, switching power supplies, etc.) However, installation combinations can occur where inter-...

  • Page 10: Entertainment Input

    Only the person who presses their PTT switch will be heard over the ra- dio. If the pilot and copilot both use the PTT, the copilot position has access to the radio. The pilot posi- tion will have PTT control regardless of the copilot when the PMA6000 is in the F mode.

  • Page 11: Transmit Interlock

    If the installation replaces a KMA-24 (series -01, -02 or -03), the existing 44 pin connector can be used for the bottom connector of the PMA6000 tray as it is, if it is properly installed and wired. A dropping resistor must be in series with the power in a 28V KMA 24 installation.

    2.4.14 Digital recorder (-IRS units only) If the PMA6000-series unit is identified with Option 1, there is an internal recorder built into the unit. This stores the last 60 seconds of radio traffic from the selected Com transceiver (the one selected for transmit).

    Split Mode. Unit Installation To install the PMA6000, remove the copilot volume and squelch knob. Gently slide the unit into the mounting rack until the hold-down screw is engaged. While applying gentle pressure to the face of the unit, tighten the 3/32" hex-head screw next to the copilot control shaft until the unit is secure. DO NOT OVER TIGHTEN.

    Post Installation Checkout 2.9.1 Required Test Equipment In order to return an aircraft to service after installation of the PMA6000-series with marker beacon re- ceiver, 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.

Rotate the mic selector switch to the C 3 position. Verify that the pilot communicates on the trans- ceiver in the Com3 position and the copilot on Com 1.

  • Page 16: Section Iii Operation

    This section is divided into four sections covering the basic operating areas of the PMA6000 systems. They are: Audio Selector, Transceiver Selection, Intercom, and Marker Beacon Receiver (6000M, 6000M-C 6000M-S and 6000M-S-C only).

    2 while Com 2 has NOT been selected, Com 1 audio will be switched off. In essence, switching the mic selector will not effect the selection of Com audio. Important: When the mic selector is in the full counter clockwise position, the PMA6000 power is re- moved, and it is in the mode.

  • Page 18: Intercom

    Adjusting the VOX-Squelch control, (6000, 6000M, 6000MC) The PMA6000 provides adjustable VOX squelch controls for the pilot and copilot (the copilot's VOX con- trol also adjusts the passengers VOX squelch). Since the number of microphones open at any one time is reduced, the amount of background noise is diminished.

    The pilot and copi- lot are individually. All passenger mics are controlled with pin 20. The same pins are used for both mono and stereo PMA6000 Systems. This applies ONLY to units with applicable serial numbers.
