1.3 EQUIPMENT DESCRIPTION

The KMA 30 is a state-of-the-art audio isolation amplifier and audio selector that contains an automatic
voice activated (VOX) intercom system and integral marker beacon receiver. It can switch two transceiv-
ers (Com 1, Com 2) and six receivers (Nav 1, Nav 2, ADF, DME, MKR and AUX).
A full duplex TEL mode allows the KMA 30 to act as an audio interface between aircraft headphone and
microphones and specific aircraft approved (FAA/FCC) cellular telephone equipment, through the front
mounted jack.
Warning: Use of non-aviation approved cellular telephone equipment may be prohibited by FCC regulation.
Bendix/King is not responsible for unauthorized airborne use of cellular telephones.
For airborne use, the KMA 30 must be interfaced with an approved system.
There are five unswitched inputs, available for traffic or EGPWS, autopilot disconnect, and/or radar al-
timeter warning, with the fifth unswitched input through a front-mounted utility jack, when configured to
act as a fifth unswitched input.
Pushbuttons select the receiver audio source provided to the headphones. A SPR button allows the user to
listen to the receiver(s) selected on the cabin speaker. Except for the unswitched inputs, all speaker audio
is muted during transmit. Unswitched inputs 1,3, and 4 are always presented to the aircraft speaker.
Unswitched input 2 will be presented to the speaker when the front panel SPR push button has been se-
lected.
Pushbutton switches select one of the communication transceivers for the pilot and copilot position, and
allows radio transmission. In "Split Mode" the KMA 30 has the ability to allow the pilot to transmit on
Com 1 while the copilot can transmit on Com 2. A fail-safe mode connects the pilot headphone and mi-
crophone to COM 1 if power is removed for any reason, or if the power switch is placed in the Off (Fail-
safe) position. Unswitched input #1 is also provided to the pilot headphone in fail-safe
A six-station voice activated (VOX) intercom is included in the KMA 30. This system has Bendix/King's
patented IntelliVox® circuitry that eliminates manual adjustments. The intercom system incorporates pilot
isolate, all and crew modes, two independent stereo music inputs with "SoftMute™". Intercom volume
control is through two concentric front panel knobs and a pushbutton intercom mode switch. The small
