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 13 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.

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.
Here are the steps it takes to replace a KMA24 with a PMA7000B:
1) remove KMA24 from tray
2) remove the connector from KMA24 tray
4) remove tray
4) install PMA7000B tray
5) install connector in PMA7000B tray
6) install PMA7000B into tray
As far as the audio panel installation is concerned, its done. GO FLY
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.
