GMA 1360D Audio Panel, Unit Only

The Garmin GMA 1360D is a vertically oriented panel mounted audio control and marker beacon system.
The system delivers reliability and versatility for all audio controlling functions. LED-illuminated push
buttons and logical panel layout allow audio selection of NAV, COM, DME, ADF, MKR, TEL, AUX,
and automatic warning audio in voice or tone annunciation. LED brightness is adjusted to a level
appropriate for ambient cockpit light conditions automatically by the GDU or manually with radio
lighting controls, depending upon installation connections. A failsafe circuit connects the pilot’s headset
and microphone directly to ON-SIDE COM in case power is interrupted or the unit is turned off.
The Garmin GMA 1360D Audio Panel incorporates a microcontroller for processing front panel key
commands, annunciator control, input/output functions, and communication.
The GMA 1360D includes a five-position intercom system (ICS) with electronic cabin noise de-emphasis
and two stereo music inputs. A dual installation extends the number of ICS positions to ten. The
intercom provides two selectable modes of isolation (Intercom ON, Intercom OFF). A pilot-selectable
cabin speaker output can be used to listen to the selected aircraft radios. The PA function is pilot
selectable and allows communication to the passengers.
The GMA 1360D provides configurable passenger volume and pilot adjustable master and ICS volume.
The GMA 1360D provides digital audio input/output capability to external radios. The unit is capable of
digitally interfacing with two transceivers and two receivers. For every channel except COM 3, the unit
generates both digital and analog outputs, and combines both digital and analog inputs.
The GMA 1360D provides a digital recorder with playback capability. Recording is selectable via the
REC button. Playback is controlled by pressing the PLAY button. The digital clearance recorder can
playback up to two and a half minutes of recording.
The marker beacon receiver with dual sensitivity and audio muting with automatic re-arming is included
in the unit.
The GMA 1360D (-20) includes a “CABIN” button, enabling cabin to cockpit communications.
