3.7 Music Muting (6)
There are two SoftMute™ muting circuits. The front panel "Mute" button has four
modes, and controls the Mute function for music 1. Music 2 muting is controlled by
an external switch, and has two modes.
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 comfortably, over a second or so.
The mute mode functions are controlled through sequential pushes of the Mute button, and include LED
indication of the mode selected.

The passenger’s 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 passenger music.

Passengers also have a Karaoke Mode. 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 passengers
are listening to the music 2 input, their Karaoke Mode is activated by an external switch.
