3D AUDIO (GMA 1360)
3D Audio is useful when multiple COM audio sources are present. By using different responses in each ear,
3D audio processing creates the illusion that each COM audio source is coming from a unique location on the
horizontal plane.
Because this feature uses different signals for left and right channels, it requires wiring for stereo intercom and
stereo headsets. If an aircraft is not wired to support stereo headsets, or the crew does not use stereo headsets,
then COMs audio will be distributed to both ears regardless of the 3D audio functionality selection.
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.
The scope of 3D audio is limited to COM audio for the pilot and copilot stations. All other audio (alerts,
side-tones, intercom, etc.) will be distributed equally to both ears.
Pilot and copilot 3D audio can be enabled or disabled. Also, the 3D audio left/right reference can be changed
using the Left-Right Swap function. This allows pilots to wear their microphone on either side of the headset
while using 3D audio.
