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 co-
pilot.
This mode is useful if your passengers have a different interest in en-
tertainment or are watching a DVD, but do not want to be excluded
from the intercom conversations.
The pilot can hear this music source in ISO mode, if desired, as fol-
lows: In the ISO mode, hold the Function (Mon 1) 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.
Music Muting
There are two SoftMute™ muting circuits.
The front panel "Mute" button has four
modes, and controls the Mute function for
music 1.
The SoftMute™ circuit will cut the music out
