5.1 AUDIO PANEL DESCRIPTION
The GMA 1347 is an audio control panel and marker beacon system. Pressing the audio panel keys controls audio selection of COM, NAV, and intercom. LED annunciators indicate when a key function is selected.
The audio panel includes a four-position intercom system (ICS) with electronic cabin noise de-emphasis and two stereo music inputs. Separate knobs control intercom audio level for the pilot and copilot/passenger. The intercom provides four selectable modes of isolation (All, Crew, Pilot, Copilot).
A cabin speaker is available for listening to selected aircraftradios. MASQ(MasterAvionicsSquelch)processing reduces ambient noise from the avionics inputs.
Each microphone input has an automatic squelch threshold. Manual squelch is available by pressing the
MAN SQ key.
The audio panel provides a digital recorder that can play back up to two and a half minutes of COM audio. Recording is automatic when a COM signal is received. PlaybackiscontrolledbypressingthePLAYkey. Playback can be stopped by pressing the MKR/MUTE key.
The unit controls marker beacon receiver audio and features marker beacon audio muting.
As part of the G1000 Integrated Cockpit System, the GMA 1347 also controls the display reversionary mode.
AUDIO PANEL
WARNING: When the GMA 1347Audio panel is turned OFF or is inoperative, certain autopilots are affected. No warning tone is supplied when the autopilot disengages and the middle marker sense signal is not supplied.
The audio panel features controls for three (3) major function groups:
•Communication
•Navigation
•Intercom system (ICS)
The controls are labeled to indicate the name of the function. The triangular annunciator above each key indicates when the key function is selected.
TheknobsatthebottomoftheunitcontrolICSvolume and squelch threshold levels. The small knob adjusts the volume/squelch level for the pilot. The large knob adjusts the volume/squelch level for the copilot/passenger. The red DISPLAY BACKUP button below the dual volume/ squelch knob controls reversionary mode selection.
TRANSCEIVERS
NOTE: A push-to-talk (PTT) switch must be pressed to transmit on the selected radio.
The audio panel handles two separate transceivers:
•COM1 MIC
•COM2 MIC

AUDIO PANEL
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 other positions, any other listener using a stereo headset hears audio in the left ear only, unless their headset has a mono/stereo switch that is set to mono.
UNMUTED/UNSWITCHED INPUTS
Theaudiopanelprovidesfour(4)unmuted/unswitched inputs that are always present on the headsets or speaker. These inputs are the following aural warnings:
•ALTITUDE WARNING
•UNSWITCHED 1
•UNSWITCHED 2
•UNSWITCHED 3
