3D AUDIO
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 all three COMs are selected,
the listener hears the audio sources at the 11, 12 and 1 o’clock positions
with the COM numbers increasing clockwise. If two COMs are selected,
the listener hears the audio sources at the 11 and 1 o’clock positions with
the COM numbers increasing clockwise. All other intercom positions are
processed to sound like their relative seat location. By default, the GMA
345 3-COM assumes the pilot sits in the left seat. A Garmin authorized
service center can make changes to the default configuration.
