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 COM1 at the 11 o'clock position and COM2 at the 1 o'clock

position. All other intercom positions are processed to sound like their

relative seat location. By default, the GMA 350H/350Hc assumes the pilot

sits in the right 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.
