FEATURES AND OPERATION
The GMA 350 Audio Panel provides the traditional audio selector functions
of microphone and receiver audio selection. The Audio Panel includes an
intercom system (ICS), a marker beacon receiver, and a COM clearance
recorder. Ambient noise from the aircraft radios is reduced by Avionics
Squelch (ASQ). When no audio is detected, ASQ processing further reduces
the amount of background noise. The MAN SQ Key toggles between manual
and automatic intercom system (ICS) squelch.
mode, threshold adjustments are handled automatically by the system. In
manual ICS squelch mode, individual threshold adjustments can be made
for the pilot, copilot, and passenger microphones by the crew. The ability to
adjust individual thresholds for each ICS position further reduces the amount
of background noise from the radios.
Pushbutton keys control audio selection. When a key is selected, a triangular
annunciator above the key is illuminated. Annunciator brightness is adjusted
automatically by photocell dimming. Key brightness is adjusted by the radio
dimming bus control. Three Aux inputs are available for additional avionics
or audio devices.
Upon installation, the unit may be configured in various ways depending
on aircraft type and the needs of the pilot.
POWER-UP
The GMA 350 performs a self-test during power-up. During the self-
test all Audio Panel annunciator lights illuminate for approximately two
seconds. Once the self-test is completed, most of the settings are restored
to those in use before the unit was last turned off.
