Passenger intercom is only available if an IntelliPAX Intercom module is used.
Passenger Music source depends on music function mode. See § 3.10.3
If the pilot panel is in ISO mode, the copilot only has ISO and ALL modes available.
The pilot forces the copilot audio panel into crew mode and the copilot can force the pilot out of
the crew mode.
I
SO
: The pilot is isolated from the intercom and is connected only to the aircraft radio system. He will hear
the aircraft radio reception (and sidetone during radio transmissions). Copilot will hear passengers’ inter-
com and entertainment, while passengers will hear copilot intercom and entertainment. All will hear aircraft
radio receptions and pilot transmissions will in the ALL mode, but if the copilot goes to the ISOLATE then
passengers will not hear radio traffic. The pilot can hear music if desired. See §3.8.1, this feature is reset at
power cycles
A
LL
: All parties will hear the aircraft radio and intercom. Crew and passengers will hear selected enter-
tainment. 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 completed.
C
REW
: Pilot and copilot are connected on one intercom channel and have exclusive access to the aircraft
radios that each crew member selects. They may also listen to Entertainment 1. Passengers can continue to
communicate with themselves without interrupting the Crew and may listen to entertainment as configured.

Music and Music Muting (6)
The PMA8000D has two independent music inputs at the rear connector, and a front panel jack. The
PMA8000D also has the ability to receive streaming music from a Bluetooth-enabled device.
Music 1 will be heard by the pilot and copilot positions. Music 1 can also be distributed to the passengers
using the Function “C” control (See § 3.11.3). The front panel jack input is treated as Music 1 ( this could
be confusing since we have a “Music #1 ALL headsets, but the FP jack doesn’t work that way ), and the
streamed music in the PMA8000D is also Music 1.
NOTE:
All music devices should be turned off for take off, landing, or any critical phase of flight. FAA Regulation
14 CFR 91.21 restricts the use of portable electronic devices.
§91.21 “(a) Except as provided in paragraph (b) of this section, no person may operate, nor may any opera-
tor or pilot in command of an aircraft allow the operation of, any portable electronic device on any of the
following U.S.-registered civil aircraft. . .
“(b)(5) Any other portable electronic device that the operator of the aircraft has determined will not cause
interference with the navigation or communication system of the aircraft on which it is to be used.”
You can refer to Advisory Circular 91.21-1A for more information, at
The front panel "Mute" button has four modes, and controls the Mute function for Music 1.
The SoftMute™ circuit will cut the music out whenever there is conversation on the radio, the intercom, or
