audio when it is active. For example, if COM 1 is selected to transmit
to ATC, but COM 2 is receiving weather information; the ATC will
mute the audio from the weather while ATC is transmitting. In Moni-
tor mode, the RCV COM indicator will blink every few seconds as a
status indication. Monitor mode is set to off when the unit is turned
off.
“Music” controls music distribution, and has three states; Standard
Music Distribution, Alternate Music Distribution and Music 1 All
Headsets.
Music 1 (Music 1 input on the rear connector) can be distributed to all
headsets depending on intercom mode.
In Standard Music Distribution, Music 1 is provided to the crew, and
Music 2 is independently provided to the passengers.
In Alternate Music Distribution, Music 1 is provided to everybody in
the ALL intercom mode, and Music 2 becomes active, for the passen-
gers only, when the intercom is in the CREW mode. The front panel
jack is also available to the passengers in the ISO and ALL intercom
modes.
The PMA8000B will announce the Alternate Intercom and Music
distribution functions at unit power up. To defeat the announcement at
power up, hold the TEL and AUX buttons for about two seconds.
The feature can be enabled using the same sequence.
NOTE: Functions are not available in the split mode.
