Alternate Intercom Mode
The PMA450 includes an Alternate Inter-
com Mode. This mode allows intercom
communications between crew and pas-
sengers, without interrupting the crew’s
radio communications. The passengers do
not hear the aircraft radio audio. The passenger microphones are muted, such
that the crew cannot hear the passengers’ microphone audio while the radio
is active. Passengers can still talk to each other.
To enable the Alternate Intercom Mode, press RADIO → Intercom: to
toggle between Standard and Alternate modes. This state is remembered
during power cycles.
Music Distribution and Music Muting
The PMA450 has two independent music
inputs at the rear connector. The PMA450
also has the ability to receive streaming
music from a Bluetooth-enabled device
which will be connected as Music #1.
The Music 1 and Music 2 inputs can be
selectively delivered to the pilot, copilot
and/or passengers using the music distri-
bution menu.
Streaming Bluetooth® Music is in parallel
with Music 1.
Press Music → Music Distribution→ and select desired combination.
NOTE:
All music devices should be turned off for takeoff, 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 operator or pilot in command of an aircraft allow
the operation of, any portable elec-
tronic 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 interfer-
ence with the navigation or communication system of the aircraft on which it
is to be used.”
