Monitor (B); Music (C) - Honeywell Bendix/King KMA 30 Manual

Bendix/King by Honeywell
KMA 30 Audio Panel and Intercom System
Installation and Operator's Manual
When "Intercom" function is toggled (hold TEL button) into "Alternate Intercom Function," the
passengers will NOT hear aircraft radios, even in the All intercom mode. They will be able to converse
with the crew. However, when the aircraft radio becomes active, the intercom audio from the passengers is
muted, allowing the crew to focus on the radio. The passengers will still be able to talk to each other.
Pressing TEL button again switches the intercom back to "Standard Intercom Function."
Alternate Intercom mode is announced at power up, unless the power on announcement has been defeated.

3.11.2 Monitor (B)

Pressing Monitor (AUX) will activate or deactivate the COM radio monitor function. When the Monitor
is on, the audio from the COM that is selected for reception only (only top LED illuminated) will be
muted when the radio that is selected to transmit becomes active.
This function is useful if you are copying weather from AWOS on COM 2, but have clearance delivery
tuned in on COM 1. With the monitor active, the AWOS audio will be silenced when clearance delivery
starts to speak.
To activate the Monitor function press and hold AUX, until audio announces "Monitor on," and the same
button again to deactivate. The unit announces"Monitor off" when deactivated.
NOTE: This mode is NOT remembered through power cycles, to prevent inadvertent blocking of desired
audio on your next trip.

3.11.3 Music (C)

The Music function button (C) allows you either send the music 1 input to all intercom stations, all of the
time, or have other distribution rules apply to your music inputs.
When "Music one all headsets" is selected (press and hold Mute), music 1 (from the rear connector input,
Pins J2 23 & 24 only) will be distributed to all headsets and is independent of the intercom mode switch.
Therefore, even in the CREW mode, the passengers will hear Music 1, even though they will not hear the
intercom or radios.
This mode allows you to use a single in-flight entertainment source aboard, and to send it everywhere,
even in crew mode. The music muting will be normal, and follow the selected mode of the crew or pas-
sengers.
Music function also allows you to configure your music to be either independent of the intercom mode, or
to make Music 2 dependent on the intercom mode.
When you press and hold Music (Mute) again, you'll hear, "Alternate Music distribution." In this case,
Music 2 will be active only when the intercom is in the CREW mode, and only the passengers will hear it.
This distribution is similar to other brands of audio panels. It allows the passengers to have their music
source come on only when they are not hearing the crew. In addition, the front panel jack input will be
distributed to the passengers in ALL and ISO mode.
Press and hold Music (Mute) again, and you will hear "Standard Music Distribution." In this mode, Mu-
sic 2 becomes active, and will always be presented to the passengers on the intercom. Music 1 is only
available to the pilot and copilot. The intercom mode switch doesn't have any affect on the music distribu-
tion.
When the music is standard, Music 1 will always go to the pilot and copilot positions, and is never heard
by the passengers. Music 2 is always heard by the passengers, and never heard by the pilot and copilot.
This mode is useful if your passengers have a different interest in entertainment or are watching a DVD,
but do not want to be excluded from the intercom conversations.
The pilot and copilot will always hear Music 1 through the unit rear connector, or a source plugged into
the front panel jack. This is present in ALL and CREW intercom modes, and available to the copilot posi-
tion in ISO mode.
