will hear Entertainment 2. During any radio or intercom communications,
the music volume automatically decreases. The music volume increases
gradually back to the original level after communications have been com-

(Down Position): Pilot and copilot are connected on one intercom
channel and have exclusive access to the aircraft radios. They may also
listen to Entertainment 1. Passengers can continue to communicate with
themselves without interrupting the Crew and also may listen to Entertain-
ment 2.
Anytime the PMA7000M is in either the Split Mode ("C

The passengers will maintain intercommunications, but never hear aircraft
radios.
Alternate Intercom Mode
If an external switch is installed for the purpose, the PMA7000M can enter
“Alternate Intercom Mode.” When the intercom is in
ALL
mode, with al-
ternate mode enabled the passengers will NOT hear the aircraft radios, but
they will hear the crew on the intercom. In addition, the crew microphones
will be blocked from the crew headsets while the radio audio is active.
Entertainment Input
The audio selector panel has provisions for two separate music input de-
vices. Music 1 feeds the pilot and copilot positions, music 2 feeds the pas-
senger positions. They operate independently in the PMA7000M.
While in the ISO (Isolate) mode, the copilot will hear Entertainment 1
while the four passengers will hear Entertainment #2. In normal operation,
whenever a person speaks, or if the aircraft radio becomes active, the music
will automatically mute and then will gradually return to the original listen-
ing level when the intercom or radio conversation ceases.
Bluetooth® Music is presented as Music 1, and heard by the pilot and copi-
lot positions. However, Bluetooth can be provided to all positions. Press
and hold the ICS button for one second, or until the Bluetooth music ap-
pears in passenger headphones.
It is also possible to use a single input device for both music inputs. How-
ever, we suggest that a switch (DPDT) be installed between the music de-
vice and music input #1. This will allow the pilot to direct the music as
desired.
Soft Mute and Soft Mute inhibit
The Soft Mute feature assures that the aircraft radio transmissions will not
be missed due to music playing. When there is radio reception or intercom
conversation, the music is muted. When the radio or intercom traffic
