1.3 EQUIPMENT DESCRIPTION
The PMA7000M-S-series is a state of the art audio isolation amplifier and audio selector that contains an
automatic 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).
The TEL mode allows the PMA7000M-S to act as an audio interface between aircraft headphone and mi-
crophones 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 PMA7000MS must be interfaced with the AirCell AGT.01.
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.
A rotary switch selects one of the three communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the PMA7000M-S has the ability to allow the pilot and copilot
to operate different transceivers independently. The TEL mode allows the pilot to use the cellular telephone
interface. External 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 rea-
son, or if the power switch is placed in the Off (Fail-safe) position.
