AUDIO PANEL AND CNS
TRANSCEIVERS
NOTE: A push-to-talk (PTT) Key must be pressed to transmit on the selected radio.
The audio panel handles two separate transceivers:
• COM1 MIC
• COM2 MIC
MONO/STEREO HEADSETS
Stereo headsets are recommended for use in this aircraft.
Using a monaural headset in a stereo jack shorts the right headset channel output to ground. While this does
not damage the audio panel, a person listening on a monaural headset hears only the left channel in both ears.
If a monaural headset is used at one of the passenger positions, any other passenger using a stereo headset hears
audio in the left ear only, unless their headset has a mono/stereo switch that is set to mono.
UNMUTED/UNSWITCHED INPUTS
The audio panel provides four unmuted/unswitched inputs that are always present on the headsets or speaker.
These inputs are the following aural warnings:
• ALTITUDE WARNING
• UNSWITCHED 1
• UNSWITCHED 2
• UNSWITCHED 3
