Power on announcement
If the Intercom or Music Distribution
has changed from the factory default,
the configuration will be played when
the unit is powered up. To defeat this
announcement, hold the TEL and
AUX buttons for two seconds. The
feature can be enabled using the
same sequence.
Music Muting (6)
There are two SoftMute™ muting
circuits. The front panel "Mute" button
has four modes, and controls the
Mute function for Music 1, front panel,
and Bluetooth.
The SoftMute™ circuit will cut the
music completely out 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 comfortably, over
a second or so.
The mute mode functions are
controlled through sequential pushes
of the Mute button, and include voice
annunciations of the mode selected.

When the KMA 30 is turned on, it
always begins in crew "Mute on"
mode.
The passengers' intercom also
has a SoftMute™ circuit. If the
passengers hear the radio, or talk on
the intercom, the music will mute. If
the audio panel is in CREW mode,
then the radio reception will not affect
the passenger music.
If the passengers are listening to
the music 1 input or front panel input,
their Karaoke Mode is controlled by
the front panel "Mute" button. If the
passengers are listening to the music
2 input, their Karaoke Mode is
activated by an external switch
installed either in the aircraft, or
connected to the AUX button logic
output pin on the KMA 30. Consult
your installer for details.
Music 1 Volume
The music level is set at the
factory at a comfortable level. We
recommend adjusting the
entertainment volume at the sources.
However, the Music 1 volume can be
adjusted from the front panel, if
desired, by pressing SPR button.
NOTE: Increasing this music level can
increase the amount of aircraft
electrical system noise as well.

adjusted from the front panel, if
