When “Music one all headsets” is selected, music 1 (or the front panel utility jack) will be distributed to all
headsets and is independent of the intercom mode switch. Therefore, even in the CREW mode, the passen-
gers will hear Music 1, even though they will not hear the intercom or radios.
This mode allows you to use a single in-flight entertainment source aboard, and to send it everywhere,
even in crew mode. The music muting will be normal, and follow the selected mode of the crew or passen-
gers.
When select Function “B,” for the alternate function, you hear “Music One Distribution, Crew.” Now, mu-
sic input 2 will follow the modes in Function “C.”
3.10.7 Function “C”
Function “C” allows you to configure your music to be either independent of the intercom mode, or to
make Music 2 dependent on the intercom mode.
When you press Function “C,” you’ll hear, “Alternate Music distribution,.” In this case, Music 2 will be
active only when the intercom is in the CREW mode, and only the passengers will hear it. This distribution
is similar to other brands of audio panels. It allows the passengers to have their music source come on only
when they are not hearing the crew.

Press again, and you will hear “Standard Music Distribution,.” In this mode, Music 2 becomes active, and
will always be presented to the passengers on the intercom. Music 1 is only available to the pilot and copi-
lot. The intercom mode switch doesn’t have any affect on the music distribution.
