A remote playback button may be installed.
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.
The SoftMute™ circuit will cut the music out whenever there is con-
versation on the radio, the intercom, or both, depending on the
“Mute” mode selected. When that conversation stops, the music re-
turns 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 annunciations of the mode selected.
Mode 1 - music will mute with either intercom or radio - MUTE but-
ton is lit. Voice annunciation is "mute on."
Mode 2 - “Karaoke” mode - music will not mute except during trans-
missions.- MUTE 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 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 au-
dio panel is in CREW mode, then the radio re-
ception 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 con-
trolled by the front panel “Mute” button. If the passengers are listen-
ing to the music 2 input, their Karaoke Mode is activated by an exter-
nal switch installed either in the panel, or connected to the AUX but-
ton logic output pin on the PMA8000B MP3.
