GMA 345 Audio Panel
FEATURES AND OPERATION
The GMA 345 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, a COM clearance recorder,
USB power jack, and Bluetooth
® audio. 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. Intercom
squelch threshold adjustments are handled automatically by the system.
Pushbutton keys control audio selection. When a key is selected, a green
annunciator on 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.
