1.3 EQUIPMENT DESCRIPTION
The PMA8000C is a state-of-the-art audio isolation amplifier and audio selector that contains an automatic
voice activated (VOX) intercom system and integral marker beacon receiver. It can switch three transceiv-
ers (COM 1, COM 2, COM 3) and six receivers (NAV 1, NAV 2, ADF, AUX (DME) and MKR).
A full duplex cellular telephone interface allows the PMA8000C to act as an audio interface between air-
craft headphone and microphones and specific aircraft approved (FAA/FCC) cellular telephone equipment,
using the Bluetooth® connectivity.
Warning: Use of non-aviation approved cellular telephone equipment may be prohibited by FCC regulation.
PS Engineering is not responsible for unauthorized airborne use of cellular telephones.
For airborne use, the PMA8000C must be interfaced with an approved system.
There are five unswitched inputs, available for traffic or EGPWS, autopilot disconnect, and/or radar altime-
ter warning, with the fifth unswitched input through a front-mounted utility jack, when configured to act as a
fifth unswitched input.
Pushbuttons select the receiver audio source provided to the headphones. A SPR button allows the user to
listen to the receiver(s) selected on the cabin speaker. Except for the unswitched inputs, all speaker audio is
muted during transmit. Unswitched inputs 1, 3, and 4 are always presented to the aircraft speaker. Un-
switched input 2 will be presented to the speaker when the front panel SPR push button has been selected.
Unswtiched input 3 is adjustable, see § 2.4.8.
Pushbutton switches allow the crew to select one of the communication transceivers (COM 1, COM 2 or
COM 3) for the pilot and copilot position, and allows radio transmission. In "Split Mode" the PMA8000C
has the ability to allow the pilot to transmit on COM 1 or COM 2, while the copilot can transmit on COM 2
or COM 3 at the same time. A fail-safe mode connects the pilot headphone and microphone to COM 1 if
power is removed for any reason, or if the power switch is placed in the Off (Fail-safe) position. Un-
switched input #1 is also provided to the pilot headphone in fail-safe
A voice activated (VOX) intercom is included in the PMA8000C. This system has PS Engineering’s patent-
ed IntelliVox® circuitry that eliminates manual adjustments. The intercom system incorporates pilot isolate,
