3D AUDIO (GMA 350 ONLY)
3D Audio is useful when multiple audio sources are present. By using different responses in each ear, 3D
audio processing creates the illusion that each audio source is coming from a unique location or seat position.
Because this feature uses different signals for left and right channels, it requires wiring for stereo intercom
and stereo headsets. If 3D audio is activated when mono headsets are in use, the listener will still hear all audio
sources; however, there is no benefit from location separation.
With a single COM selected and 3D Audio enabled, the listener hears the audio source at the 12 o’clock
position. If both COMs are selected, the listener hears COM1 at 11 o’clock and COM2 at the 1 o’clock position.
All other intercom positions are processed to sound like their relative seat location. By default, the GMA350
assumes the pilot sits in the left seat. A Garmin authorized service center can make changes to the default
configuration.

Press and hold the
PILOT
Key to toggle 3D audio processing on and off for all headset positions. When
3D Audio is enabled, the aural message “3D audio left” is heard in the left ear followed by “3D audio right”
in the right ear. If the aural messages are not heard in only the left and then the right ear respectively, the
cause may be aircraft wiring or headset settings. Refer to the following table if a headset or aircraft wiring
problem is suspected.
