FEATURES AND OPERATION

The GMA 345 3-COM 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

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.
