When “Music one all headsets” is selected (press and hold Mute), music 1 (from the rear connector input,
Pins J2 23 & 24 only) will be distributed to all headsets and is independent of the intercom mode switch.
Therefore, even in the CREW mode, the passengers 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 pas-
sengers.
Music function also 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 and hold Music (Mute) again, 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. In addition, the front panel jack input will be
distributed to the passengers in ALL and ISO mode.
Press and hold Music (Mute) again, and you will hear “Standard Music Distribution.” In this mode, Mu-
sic 2 becomes active, and will always be presented to the passengers on the intercom. Music 1 is only
available to the pilot and copilot. The intercom mode switch doesn’t have any affect on the music distribu-
tion.
When the music is standard, Music 1 will always go to the pilot and copilot positions, and is never heard
by the passengers. Music 2 is always heard by the passengers, and never heard by the pilot and copilot.
This mode is useful if your passengers have a different interest in entertainment or are watching a DVD,
but do not want to be excluded from the intercom conversations.
The pilot and copilot will always hear Music 1 through the unit rear connector, or a source plugged into
the front panel jack. This is present in ALL and CREW intercom modes, and available to the copilot posi-
tion in ISO mode.
The pilot can hear this music source in ISO mode, if desired, as follows: In the ISO mode, hold the (Mu-
sic) button, and press the ICS mode button for more than one second. The ICS mode LED will blink
slowly to indicate music is connected to the pilot headset, although the intercom is not.
Music 2 is provided to the passenger positions regardless of intercom mode, when the audio panel is in
Standard Music Distribution, and also in Alternate Music Distribution, but only if the intercom is in the
CREW mode. The pilot and copilot can never hear Music 2, under any condition.
If the passengers always want to hear the source in Music 1, input through the rear connector, regardless
of the intercom mode (ISO/ALL/CRW), select “Music 1 all headsets.”
If the passengers want to hear the music input through the front panel jack, the audio pane MUST be in
Alternate Music Distribution, and the intercom must be in the ALL or ISO mode.
