Page 2 202-890-0514 PMA8000E Pilot Guide Rev. 1
This pilot’s guide provides operating instructions for the PMA8000E Audio
Panel for dual panel systems. Please read it carefully before using the equip-
ment so that you can take full advantage of its capabilities.
This guide is divided into main operating sections such as Transceiver Selec-
tion, Audio Selector, Intercom, and Marker Beacon Receiver, and special
functions. The center section provides a reference that you can remove.
Power Switch (1) (EMG-Fail Safe Op-
eration)
The power switch controls all audio selector
panel functions, intercom and marker beacon
receiver.
When the unit is turned off, either by pressing the vol-
ume control, or if the breaker is pulled remov-
ing power, the PMA8000E is in Fail-Safe
mode. In this mode, the crewmember’s headset
is connected to COM 1 for transmit and re-
ceive. The fail safe audio will only be heard in
the left ear of a stereo headset.
NOTE: In the event of failure in both audio panels,
both will default to COM 1. If both crew mem-
bers attempt to transmit at the same time, the
modulation may be compromised, depending
on the microphones used. Therefore, only one
crew member should transmit if both audio
panels fail.
Communications Transmit (XMT) Se-
lection (2)
To select COM 1 COM 2 or TEL for transmit, press
the button on the bottom row, next to the XMT leg-
end. The bottom and top button indicators
light, showing that you will transmit and re-
ceive on the selected radio.
Only one transmitter can be selected by each
crew member at a time. If both the pilot and
copilot select the same transmitter, the pilot
will have priority for radio push-to-talk.
Swap Mode (Switch from COM 1 to
COM 2 or TEL remotely)
With a yoke mounted, normally open momentary
switch, the pilot can change from the current COM

If pilot would like privacy, then they can select the ISO mode on his audio
panel. Only his headset will be connect to his Bluetooth telephone.
If the pilot would like to include the copilot then they can select the CREW
mode and this will allow pilot and copilot to speak on the pilots phone call.
The pilot will still have complete access to the aircraft radios, and will trans-
mit on the selected com when he uses the radio push-to-talk.
The copilot can connect their Bluetooth telephone to the copilot’s audio
panel.
If copilot would like privacy, then they can select the ISO mode on his audio
panel. Only his headset will be connect to his Bluetooth telephone.
If the copilot would like to include the pilot then they can select the CREW
mode and this will allow pilot and copilot to speak on the pilots phone call.
Cell phone Sidetone
As shipped, the PMA8000E audio panels provide cellular telephone sidetone
(the user’s voice fed back to the headset). Some cell phones provide side-
tone. In PMA8000E audio panels, Telephone sidetone can be disabled by
pressing the AUX button for more than one second.
Music Input
When used as a music input Bluetooth music are treated as Music #1. Using
the Music function button, it can be distributed to all users, depending on the
intercom mode.
Music and Music Muting (6)
The PMA8000E has two independent music inputs at the rear connector. The
PMA8000E also has the ability to receive streaming music from a Bluetooth-enabled
device.
Music 1 will be heard by the crewmember positions in each audio panel unless they
are in the ISOlate mode. The Bluetooth streamed music in the PMA8000E is also
Music 1.
The front panel "Mute" button controls the Mute on or off function for Music 1.
The SoftMute™ circuit will cut the music out whenever there is conversation on the
radio, the intercom, or both, depending on the “Mute” mode selected. When that
conversation stops, the music returns to the previous level comfortably, over a second
or so.
Internal Recorder System
The Internal Recording System is a continuous loop recorder, (last message received
will be the first heard), the recorder has 45 seconds of recording time, or up to eight
messages. The system automatically begins to record the instant the radio selected for
transmit becomes active. Only the crewmember will hear the playback audio from
their audio panel.
To play back the last recorded message, you press and hold the COM RCV pushbut-
ton associated with the selected radio transmitter for about one second. You must
wait for the message to stop playing before accessing the prior message. To cancel
the playback, press and hold the playback button for two seconds. The next time the
