  • That's an old audio panel that's pretty simple to use. Ryanb, Aug 18, 2017 #2. Pat Elliott Pre-Flight. I'm looking for a Bendix King KMA-20 service manual, I'm.
  • The audio panel in question was the KMA 24, probably one of the most common audio panels found in planes. In an overall view, the KMA 24 audio panel has two rows of buttons, flanked on the left by marker beacon lights and on the right by a rotary knob whose principle function allows the user to select COM 1 or COM 2.

The PMA7000 series audio panel not only provides a great set of capabilities, it also lends itself nicely for upgrading an existing Bendix/King KMA24 audio panel. The PMA7000B is KMA24 pin compatible, making the cost of the upgrading less expensive. None of the existing wires going to the KMA24 have to be disturb, only a new intercom wire harness has to be built, reducing the amount of installation time.

With our renown 6-place IntelliVox® automatic Voice Operated Relay (VOX) intercom system, adjusting a squelch circuit is a thing of the past. And with over 20+ years of field experience, find out just how easy it is to forget you are even using an intercom, it just works! No more clipping or missed syllables.

The PMA7000B provide 3-com capability with the option to easily convert Com 3 to a full duplex cellular telephone interface. It also has our pioneered 'Split Mode'. This allows the pilot to be on Com 1 while the copilot is on Com 2, freeing up the pilot to work with ATC while the copilot gets weather information or finds out just where the lowest fuel cost is on the field while still in the air.

Check list of capabilities:

  • IntelliVox® automatic VOX system with individually gated microphone
  • 6 Place hi-fi stereo intercom with Soft Mute™
  • 2 music mute modes: Mute On and Mute Off (ICS button)
  • Built-in Marker Beacon Receiver
  • Hardwired Satelite Telephone connection (in lieu of Com 3) which provides provides dedicated On/Off hook switches for unprecedented flexibility
  • Split mode for dual audio panel capability

  • 3 isolation modes - Pilot Isolate, All, and Crew
  • 4 unswitched inputs
  • Selectable music muting for passengers
  • Selectable special intercom mode with 'Alternate Intercom Mode'
  • RAM (Radio Active Mute) eliminates constant back ground noise from radio static
  • 2-year Pro-Support Warranty

The only knob that is on the panel is a concentric volume control for the Crew and Passengers intercom volume. The all push button controls of the PMA7000B allows for easy selection of Coms and other Nav aids.

The PMA7000B has four un-switched and un-muted inputs. This adds flexibility when installed with today's advanced warning systems, like Skywatch or TAWS.

You will not have any intercom functions until that portion of the install is completed.

That's why there is second connector. This connector must be wired by your avionics shop that will provide all of the intercom functions, telephone interface, and music inputs.

The PMA7000B is plug and play with the original PMA7000M-S, the PMA6000M-S, and the KMA28.
