Music Muting
The SoftMute™ circuit will mute the music whenever there is conversation
on the radio, the intercom, or both, depending on the “Mute” mode selected.
When that conversation stops, the music returns to the previous level over a
second or so.
The mute mode functions are controlled through Music Mute Menu which
has three modes for music inputs, ALL, Karaoke & Radio mute.

ALL – music will mute with either intercom or radio

Karaoke – music will not mute except during outgoing radio transmis-
sions.

Radio – Radio will mute music, but intercom will not mute music.
The PMA450 always defaults to Mute ALL when turned on.
In addition to the panel mute menu, a remote switch may be installed to al-
low the passengers local access to their Karaoke mode. When this switch is
grounded, the menu choice is overridden.
Music Volume
The volume of the music inputs can also
be adjusted from the menu of the
PMA450:
Press Music → Music Volume → set
desired music input. The LED Volume
bar and the numeric volume will show the
volume level.
Music in Pilot ISO mode
When the isolate (ISO) mode is activated, the music for the pilot is automati-
cally disabled. If desired, the pilot can elect to hear Music #1 or #2, in the
ISO mode by selecting through the menu screen.
The pilot can select either music source from the Music distribution menu.
Holding the ICS button, while in the ISO mode will restore the pilot’s music
selection.
Bluetooth® connection
The PMA450 has a Bluetooth interface.
The audio panel is always
“discoverable,” so you just need to
search for the PMA450 from your Blue-
tooth-equipped phone or music source.
The default access code is 0000.
When Bluetooth is active, a Bluetooth icon and the battery status of the de-
vice is displayed in the upper right corner of the home display.
