1.3 EQUIPMENT DESCRIPTION
The PMA8000BT is a state-of-the-art audio isolation amplifier and audio selector that contains an automat-
ic voice activated (VOX) intercom system and integral marker beacon receiver. It can switch two transceiv-
ers (Com 1, Com 2) and six receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX).
A full duplex TEL mode allows the PMA8000BT to act as an audio interface between aircraft headphone
and microphones and specific aircraft approved (FAA/FCC) cellular telephone equipment, through the front
mounted jack.
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 PMA8000BT 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.
Unswitched input 2 will be presented to the speaker when the front panel SPR push button has been select-
ed.
Pushbutton switches select one of the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the PMA8000BT has the ability to allow the pilot to transmit on
Com 1 while the copilot can transmit on Com 2. A fail-safe mode connects the pilot headphone and micro-
phone to COM 1 if power is removed for any reason, or if the power switch is placed in the Off (Fail-safe)
position. Unswitched input #1 is also provided to the pilot headphone in fail-safe
A six-station voice activated (VOX) intercom is included in the PMA8000BT. This system has PS Engi-
neering’s patented IntelliVox® circuitry that eliminates manual adjustments. The intercom system incorpo-
rates pilot isolate, all and crew modes, two independent stereo music inputs with "SoftMute™". Intercom
volume control is through two concentric front panel knobs and a pushbutton intercom mode switch. The
