1.3 EQUIPMENT DESCRIPTION
The PMA7000-series is a state of the art audio isolation amplifier and audio selector that contains an auto-
matic voice activated (VOX) intercom system. It can switch up to three transceivers (Com 1, Com 2 and
Com 3) and six receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX).
A duplex COM 3 mode (selectable at installation) allows the PMA7000 to act as an audio interface be-
tween aircraft headphone and microphones and specific aircraft approved (FAA/FCC) cellular telephone
equipment.
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 PMA7000CD must be interfaced with an approved system.
There are two unswitched inputs, for autopilot disconnect, and/or radar altimeter warning. Push buttons
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 dur-
ing transmit.
Push button switches selects one of the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the PMA7000CD has the ability to allow the pilot and copilot to
operate different transceivers independently. The Com 3/TEL mode (selected at installation) allows the
pilot to use the audio panel for duplex operation, such as with aviation-specific cellular telephones. Exter-
nal switches permit telephone operation for the copilot and passengers.
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.
