Pushing Function “A” again will toggle to the other mode. In this case, the Front Jack Music makes the
front panel utility jack a music source, as a convenient place to plug in an iPod. You will hear, “ Front
Jack, Music with muting.” This music input will act just like a standard music input of the audio panel,
allowing either SoftMute or karaoke modes.
If you plug a telephone into the jack, it will function as full duplex phone when the “TEL” button is
pressed, regardless of the Function “A” selection. If Function A is set for priority, any ringer audio will
come into the pilot and copilot headphones at the same level as a radio input. If the jack is set for music,
any ringer audio will be treated as music, and mute according to the rules.
We’ve built some intelligence into the PMA8000B, too. If you have Music 1 connected to the rear pins,
and there is music playing, the PMA8000B “knows” that what you put into the front jack must be a prior-
ity. So the unit will automatically switch the jack to the priority mode.
3.10.6 Function “B”
Function Button “B” allows you either send the music 1 input to all intercom stations, all of the time, or
have the normal rules apply to our music inputs.
When “Music one all headsets” is selected, music 1 (or the front panel utility jack) will be distributed to
all headsets and is independent of the intercom mode switch. Therefore, even in the CREW mode, the
passengers will hear Music 1, even though they will not hear the intercom or radios.
This mode allows you to use a single in-flight entertainment source aboard, and to send it everywhere,
even in crew mode. The music muting will be normal, and follow the selected mode of the crew or pa s-
sengers.
When select Function “B,” for the alternate function, you hear “Music One Distribution, Crew.” Now,
music input 2 will follow the modes in Function “C.”
3.10.7 Function “C”
Function “C” allows you to configure your music to be either independent of the intercom mode, or to
make Music 2 dependent on the intercom mode.
When you press Function “C,” 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. This distribu-
tion is similar to other brands of audio panels. It allows the passengers to have their music source come on
only when they are not hearing the crew.
