mute for incoming radio or intercom conversation.
The passenger’s intercom also has a SoftMute™ circuit. It behaves
the same way as the crew; if the passengers will 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 con-
trolled by the front panel button labeled "Mute". If the passengers are
listening to the music 2 input, their Karaoke Mode is activated by an
external switch installed either in the panel, or connected to the AUX
button logic output pin on the PMA8000B.
Music 1 Volume
In general, we recommend adjusting the entertainment volume at the
sources, and only using this as a master gain control. However, the
Music 1 PMA8000B input can be adjusted from the front panel, if
desired, by pressing the combinations of keys listed.
Hold the AUX button, and repeatedly push the Mute (volume up) or
SPR (volume down) to step the volume level. There are 32 steps.
•
AUX + Mute, increase volume
•
AUX + SPR, decrease volume

made intercom harness must be used for the warranty to be valid.
