tercom audio distribution, and allows the crew to mute passengers’ intercom
feed when radios are active.
The “Monitor” function mutes the secondary communication radio audio
when the primary radio (the one selected to transmission) is active.
“Music” function controls how music is distributed in your airplane.
There are two music sources available to the PMA8000BT, in addition to the
Bluetooth stream. 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 function selection annunciations and recorder playback
can be adjusted through a hole on the top of the unit marked “ANN VOL.”
“Intercom” Function
Function Intercom controls the distribution of aircraft radio and passenger
intercom. In the “Standard intercom function” mode, aircraft
radios are distributed to all, when the intercom is in the ALL
mode. In CREW mode, only the pilot and copilot positions
will hear aircraft radios.
When in “Alternate Intercom Function,” the passengers will
NEVER hear aircraft radios, even in the ALL mode. In addi-
tion, when in the ALL intercom mode, passengers will be able to converse
with the crew, unless the aircraft radio becomes active, when the intercom
audio from the passengers to the pilot and copilot is stopped, so the crew can
focus on the radio. Passengers will always be able to talk to each other.
To activate this function hold the TEL button until the audio announces
“Alternate Intercom Function,” when activated, and “Standard Intercom
Function” when deactivated.” The alternate intercom mode is announced at
power up, unless the power on announcement has been defeated.
“Monitor” Function
This function turns the Monitor Function on and off.
When the Monitor is on, the audio from the COM that is selected for reception only
(only top LED illuminated) will be muted when the radio that is
selected to transmit becomes active.
This function is useful if you are copying weather from AWOS on
COM 2, but have clearance delivery tuned in on COM 1. With the
monitor active, the AWOS audio will be silenced when clearance
delivery starts to speak.
To activate the Monitor Function press and hold AUX. The
audio will announce “Monitor on,” when activated, and “Monitor off” when deacti-
vated
NOTE: This mode is NOT remembered through power cycles, to prevent inadvertent
blocking of desired audio on the next trip.
