    If the PMA6000B is installed in a 27.5 VDC aircraft system, a 15 , 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 8: Mounting Requirements

    2.3.2 Mounting Requirements The PMA6000B must be rigidly mounted to the instrument panel of the aircraft structure and within view and reach of the pilot position(s). Installation must comply with FAA Advisory Circular AC 43.13-2B. The unit may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist.

  • Page 9: Entertainment Input

    There must be at least 13.8 VDC present at the bottom connector, pin 43, of the PMA6000B 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 interfer-...

    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 position will have PTT control regardless of the copilot when the PMA6000B is in the F mode.

    The MM Sense output Pin 27, is connected to certain specific autopilots, and goes high only when a middle marker signal is received, not in test. 2.4.10 Unswitched Inputs The PMA6000B has two unswitched inputs. pin 7 and pin 22 are unswitched/unmated inputs that are heard by the crew and over the cockpit speaker at all times. 200-066-0200 Page 2-6 Rev 6, Feb.

  • Page 13: 2.4.11 Intercom

    All mic and headphone jacks must have insulating washers, the cable must be Teflon coated, twisted- shielded wire, and the shield must only be connected to the ground return wire only at the intercom con- nector. Note: A custom wiring harness is available from PS Engineering, along with 4-place jack kits. Visit www.ps-engineering.com Adjustments The PMA6000 is factory adjusted to accommodate the typical requirements for most aircraft configurations.

    Panel/Intercom Systems. Please read it carefully before using the equipment so that you can take full ad- vantage of its capabilities. This guide is divided into sections covering the basic operating areas of the PMA6000B systems. They are: Audio Selector, Audio Selection, Intercom, and Marker Beacon Receiver (if equipped).

  • Page 17: Volume Control (2)

    Only the person who presses their Push-To-Talk (PTT), will be heard over the aircraft radio. The PMA6000B-Series has an automatic selector mode. Audio from the selected transceiver is automatical- ly heard in the headsets and speaker (when selected). You can check this function by switching from C to C 2 and watch the selected audio light on the selector change from Com 1 to Com 2.

  • Page 18: Split Mode

    3.7.1 Adjusting the VOX-Squelch control (6) The PMA6000B provides a single VOX squelch control for the pilot, copilot and the passengers, although each microphone has it’s own squelch circuit, and only a microphone spoken into will be open. Since the number of microphones open at any one time is reduced, the amount of background noise is diminished.

    They may also listen to Entertainment 1. Passengers can continue to communicate with themselves without interrupting the Crew and also may listen to Entertainment 2. Anytime the PMA6000B is in "Split Mode" the pilot and copilot do not have any intercom function. The passengers will maintain intercommunications.
