1.3 EQUIPMENT DESCRIPTION
The PMA9000EX is a state-of-the-art audio isolation amplifier and audio selector that contains an aut o-
matic voice activated (VOX) intercom system and integral marker beacon receiver. It can switch two
transceivers (Com 1, Com 2) and six receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX).
A full duplex TELEPHONE mode allows the PMA9000EX 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 regulation.
PS Engineering is not responsible for unauthorized airborne use of cellular telephones.
For airborne use, the PMA9000EX must be interfaced with an approved system.
There are five unswitched inputs, available for traffic or EGPWS, autopilot disconnect tones, and/or radar
altimeter 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 se-
lected.
Pushbutton switches select one of the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the PMA9000EX 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
microphone 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
