These functions are non-essential and non-required and as such are

only an accessory capability. They don’t affect the audio panel’s pri-

mary function as a selector panel, aircraft intercom, or marker beacon

receiver. You can’t do anything with these buttons to prevent the

PMA8000B MP3 from doing its main job.

Looking at the front panel you’ll notice that the Mon1, Mon 2, Mute

and SPR buttons have “Function” assignments.

To use these function keys A, B, C – press and hold “F” (MON 1) and

then press the desired key, “A” “B” or “C”. If making multiple

changes, you must release the Shift button between function changes.

There are three special functions. Function Button “A” is related to

the intercom function, and allows the crew to mute passengers’ inter-

com feed when radios are active.

Function Buttons “B” and “C” control how music is distributed in

your airplane.

There are two music sources available to the PMA8000B MP3. Music

1 input can be either on the front jack, OR the Music 1 input at the

rear connector (Pins 23 and 24, J2). Music 2 is wired into the rear

connector, only (Pins 26 and 27, J2)

The volume of the audio annunciations and recorder playback can be

adjusted through a hole on the top of the unit marked “ANN VOL.”

Function “A”

Function “A” controls the distribution of aircraft radio within the in-

tercom, as well as passenger intercom muting. In the “standard inter-

com function” mode, aircraft radios are distributed to all, when the

intercom is in the ALL mode. In CREW mode, only the pilot and co-

pilot positions will hear aircraft radios.

When Function A is toggled into “Alternate Intercom Function,” the

passengers will NOT hear aircraft radios, even in the All mode. In

addition, when in the ALL mode, passengers will be able to converse

with the crew. However, when the aircraft radio becomes active, the

intercom audio from the passengers to the crew is muted, allowing the

crew to focus on the radio. Passengers will continue be able to talk to

each other.
