1.2 SCOPE
This manual provides detailed installation and operation instructions for the PS Engineering PMA8000G-
series of Audio Selector Panel/Intercom Systems. This includes the following units:
1.3 EQUIPMENT DESCRIPTION
The PMA8000G 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 two transceivers
(Com 1, Com 2) and four receivers; Nav 1, Nav 2, MKR and AUX (ADF & DME).
A full duplex TEL mode allows the PMA8000G to act as an audio interface between aircraft headphone
and microphones and specific aircraft approved (FAA/FCC) cellular telephone equipment, through the
Bluetooth connection.
Warning: Use of non-aviation approved cellular telephone equipment may be prohibited byFCC regulation.
PS Engineering is not responsible for unauthorized airborne use of cellular telephones.
For airborne use, the PMA8000G must be interfaced with an approved system.
There are four unswitched inputs, available for traffic or EGPWS, autopilot disconnect, and/or radar altime-
ter warning.
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
allow radio transmission. In "Split Mode" the PMA8000G 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 PMA8000G. This system has PS Engineer-
ing’s patented IntelliVox® circuitry that eliminates manual adjustments. The intercom system incorporates
pilot isolate, all and crew modes, two independent stereo music inputs with "SoftMute™". Intercom vol-
ume control is through two concentric front panel knobs and a pushbutton intercom mode switch. The small
