GMA 345 3-COM Audio Panel

The 2-COM version of the GMA 345 (below) is described in the

NOTE:

GMA 345 Pilot's Guide (Part Number: 190-01878-01).

POWER-UP

The GMA 345 3-COM 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.

MONO/STEREO HEADSETS

Stereo headsets are recommended when using the GMA 345 3-COM.

Using a monaural headset in a stereo jack shorts the right headset channel

output to ground. While this does not damage the Audio Panel, a person

listening on a monaural headset hears only the left channel in both ears.

If a monaural headset is used at one of the passenger positions, any other

passenger using a stereo headset hears audio in the left ear only.

LEFT/RIGHT KNOBS

The Left Inner Knob powers-off the unit, and is used to control left

seat crew member ICS volume. The Left Outer Knob controls left seat

crew member music volume. The Right Inner Knob controls right seat

crew member ICS volume. The Right Outer Knob controls the right seat

crew member music volume. The seat considered the pilot position is

configurable for either left or right depending on the aircraft' s needs and is

set during installation. Passenger ICS and music volume is adjusted by the

knobs on the side associated with copilot.
