Function “C” also allows you to configure your music to be either independ-
ent of the intercom mode, or to make Music 2 dependent on the intercom
mode.
When you press Function “C,” 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. Music 1 (Bluetooth, Rear input, and Front Panel
Jack) will be provided to passengers’ headset in ISO and ALL intercom modes.
Press again, and you will hear “Standard Music Distribution.” In this mode, Music 2
becomes active, and will always be presented to the passengers. Music 1 is only
available to the pilot and copilot. The intercom mode switch will not have any affect
on the music distribution.
When the music is standard distribution, Music 1 will always go to the pilot
and copilot positions, and is never heard by the passengers. Music 2 is al-
ways heard by the passengers, and never heard by the pilot and copilot.
This mode is useful if your passengers have a different interest in entertain-
ment or are watching a DVD, but do not want to be excluded from the inter-
com conversations.
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 whenever there is conversation
on the radio, the intercom, or both, depending on the “Mute” mode selected.
When that conversation stops, the music returns to the previous level com-
fortably, over a second or so.
The mute mode functions are controlled through sequential pushes of the
Mute button, and include voice annunciations of the mode selected.
• Mode 1 - music will mute with either intercom or radio - MUTE button
is LED lit. Voice annunciation is "mute on."
• Mode 2 - “Karaoke” mode - music will not mute except during radio
transmissions.- MUTE button LED is OFF. Annunciation is "mute off."
• Mode 3 - Radio will mute music, but intercom will not mute music -
MUTE LED is OFF. Annunciation is "radio mute."
• Mode 4 - Radio will not mute music, intercom will mute music - MUTE
LED is OFF. Annunciation is "intercom mute."
The passengers’ intercom also has a SoftMute™ circuit. If the passengers
hear the radio, or talk on the intercom, the music will mute. If the audio
panel is in CREW mode, then the radio reception will not affect the passen-
ger music.
If the passengers are listening to the music 1 input or front panel input, their
Karaoke Mode is controlled by the front panel “Mute” button. If the passen-
gers are listening to the music 2 input, their Karaoke Mode is activated by an
external switch installed either in the aircraft, or connected to the AUX but-
ton logic output pin on the PMA8000BT. Consult your installer for details.
