AUXILIARY AUDIO INPUT JACK
An auxiliary audio input jack (AUX AUDIO IN) is located on the center
pedestal, refer to Figure 7-2. It allows entertainment audio devices such
as cassette, compact disc, and MP3 players to play music over the
airplane's headsets.
The signal from AUX AUDIO IN is automatically muted during radio
communications or pilot selection of crew intercom isolation modes
located on the audio panel. The AUX key on the audio panel does not
control the AUX AUDIO IN signal. For a more complete description and
operating instructions of the audio panel, refer to the Garmin G1000
CRG.
Since the entertainment audio input is not controlled by a switch, there
is no way to deselect the entertainment source except to disconnect the
source at the audio input connector. In the event of a high pilot
workload and/or heavy traffic, it is wise to disable the entertainment
audio to eliminate a source of distraction for the flight crew.
NOTE
•
Passenger briefing should specify that AUX AUDIO IN
(entertainment audio input) and Portable Electronic
Device (PED) use is permitted only during the enroute
phase of flight.
•
Disconnect the cable from the AUX AUDIO IN jack when
not in use.
•
Use caution with audio cables in the cabin to avoid
entangling occupants or cabin furnishings and to prevent
damage to cables.
