or intercom communications, the music volume automatically decreases.
The music volume increases gradually back to the original level after
communications have been completed.
C REW : Pilot and copilot are connected on one intercom channel and
have exclusive access to the aircraft radios. They may also listen to En-
tertainment 1. Passengers can continue to communicate with themselves
without interrupting the Crew and may listen to Entertainment 2.
Entertainment Input and Muting Control (6)
The PMA8000-SR has multiple entertainment configurations available.
Consult with your installer before your installation to be sure your sys-
tem works the way you would like it to operate. The internal SIRIUS
Satellite radio may be connected to Entertainment #1, #2, or both. Enter-
tainment #1 is heard by the pilot and copilot
(crew) , and Entertainment 2 is heard by the
passengers. The “Mute” pushbutton has no
effect on #2 music inputs, allowing inde-
pendent entertainment from the mode of the
intercom. The intercom volume control does
not affect the music level.
While in the ISO (Isolate) mode, the copilot
will hear Entertainment #1 while the four passengers will hear Entertain-
ment #2. The Entertainment #1 will mute when either the copilot or pilot
speaks, and Entertainment #2 mutes when the passengers speak. With
our Soft Mute™ , the music will return gradually to the original listening
level when the intercom or radio conversation ceases. While in ISO
mode, the Pilot will not mute the music if he presses the PTT switch to
transmit or if he speaks while on the phone.
The entertainment inputs automatically mute when there is radio traffic
or intercom conversation. In many cases, the muting is not desired, so
mute inhibit, or “Karaoke Mode” is available. This is accomplished for
the crew by pressing the “Mute” pushbutton, turning the green LED on.
The unit can be wired so that AUX will put the music 2 music into Kara-
oke mode for the passengers. An external switch located by the passen-
gers can also be installed in lieu of the AUX button function.
