A Cirrus Perspective ™ by Garmin – Pilot’s Guide for the SR20/SR22/SR22T 145AUDIO PANEL AND CNSSYSTEMOVERVIEW FLIGHTINSTRUMENTS EIS AUDIO PANEL& CNS FLIGHTMANAGEMENT HAZARDAVOIDANCE AFCS ADDITIONALFEATURES APPENDICES INDEX3D AUDIO (GMA 350 ONLY)3D Audio is useful when multiple audio sources are present. By using different responses in each ear, 3Daudio 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 intercomand stereo headsets. If 3D audio is activated when mono headsets are in use, the listener will still hear all audiosources; 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’clockposition. 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 GMA350assumes the pilot sits in the left seat. A Garmin authorized service center can make changes to the defaultconfiguration.enABling 3d AudioPress and hold the PILOT Key to toggle 3D audio processing on and off for all headset positions. When3D 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, thecause may be aircraft wiring or headset settings. Refer to the following table if a headset or aircraft wiringproblem is suspected.
