When the PMA8000BT is turned on, it always begins in “Mute on” mode.
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 acti-
vated by an external switch installed either in the aircraft, or con-
nected to the AUX button logic output pin on the PMA8000BT.
Consult your installer for details.
Music 1 Volume
The music level is set at the factory at a comfortable level. We rec-
ommend adjusting the entertainment volume at the sources. However, the
Music 1 volume can be adjusted from the front panel, if desired, by pressing
SPR button.
NOTE: Increasing this music level can increase the amount of aircraft elec-
trical system noise as well.
The Music 1 volume can be adjusted from the front panel, if desired, by
pressing and holding the Music Volume (SPR) key.
Press the Music Volume (SPR) for more than one second, a tone will be
heard indicating the volume level is changing and the music volume will
begin to change. The volume will either increase or decrease, depending on
the last action. To reverse the volume change, release the
Music Volume
( SPR ) button, and press and hold again, and the volume will change. Con-
tinue to hold until the desired level is reached.
Note: Since it is possible to turn the volume completely off, you may need to
turn the volume up if you don’t hear music when you expected to.
It will take about 12 seconds to go from minimum to maximum volume.
