Headset and Microphone Installation
The airplane is equipped with provisions for five Active Noise
Reduction (ANR) and three conventional (MIC/HEADPHONES)
headsets. Headset jacks for the pilot, front, and rear seat passenger
are located in the map case.
The forward headset mics use the remote Push-To-Talk (PTT)
switches located on the top of the associated control yoke grip. The
rear headsets do not have COM transmit capabilities and do not
require PTT switches. Audio to headsets is controlled by the individual
audio selector switches on the audio control panel
Audio Input Jack
The aircraft contains multiple audio input jacks which can be used to
connect personal entertainment devices into the cabin sound system.
Two 3.5 mm audio input jacks (AUDIO INPUT) are provided on the
center console. One jack is located near the convenience outlet for
use by the pilot and forward passenger, and the other is located on the
aft portion of the center console for the rear passengers.
Distribution of a device connected to the forward jack is through the
MUS 1 selection on the audio panel. Distribution of the rear jack is by
the MUS 2 selection on the audio panel. A third jack on the audio
panel will also accept an entertainment input. A device connected to
this jack is distributed by selecting the Entertainment button (shown as
a phone and music-note symbol) on the audio panel. Audio volume
can be controlled by the device itself and can be further refined by the
audio panel distribution volume control.
