4.5 ADDITIONAL AUDIO PANEL FUNCTIONS
POWER-APPLICATION
The Audio Panels perform a self-test during power application. During the self-test all Audio Panel
annunciation 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 for use in this aircraft.
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.
SPEAKER (GMA 1347)
All of the radios can be heard over the cabin speaker. Pressing the
SPKR
Key selects and deselects the cabin
speaker. Speaker audio is muted when the PTT is pressed. Certain aural alerts and warnings (autopilot, traffic,
altitude) are always heard on the speaker, even when the speaker is not selected.
The speaker volume is adjustable within a nominal range. Contact a Garmin-authorized service center for
volume adjustment.
SPEAKER (GMA 1360)
All of the radios can be heard over the cabin speaker. Pressing the
SPKR/PA
Key selects and deselects the
cabin speaker. Speaker audio is muted when the PTT is pressed. Certain aural alerts and warnings (autopilot,
traffic, altitude) are always heard on the speaker, even when the speaker is not selected.
The speaker volume is adjustable within a nominal range. Contact a Garmin-authorized service center for
volume adjustment.
PASSENGER ADDRESS MODE (PA MODE)
Press and hold the
SPKR/PA
Key for 2 seconds to initiate the Passenger Address Mode. Active PA Mode is
annunciated by the PA Annunciation on the audio panel. When in PA Mode the crew can use the PTT “Push-
to-Talk” button to deliver announcements over the speaker, to the passenger headsets, or both depending on
configuration.
INTERCOM (GMA 1347)
The Audio Panel includes a six-position intercom system (ICS) and two stereo music inputs for the pilot,
copilot and up to four passengers. The intercom provides Pilot and Copilot isolation from the passengers and
aircraft radios.
