The PS ENGINEERING PMA7000 series of TSO'd audio panels offer a very affordable upgrade for existing BENDIX KING KMA24 units while providing a a great set of capabilities. The PMA7000B with built in Marker Beacon is KMA24 pin compatible. Existing wiring to the KMA24 can be maintained making the cost of the upgrading less expensive. In addition, it is plug and play with the original PMA7000M-S, the PMA6000M-S, and the KMA28 audio panels. PMA7000 series audio panels feature  6-place IntelliVox® automatic Voice Operated Relay (VOX) hi-fi stereo intercom system with Soft Mute™. The PMA7000B provide 3-com capability with the option to easily convert Com 3 to a full duplex cellular telephone interface  and "Split Mode" allowing the pilot to be on Com 1 while the copilot is on Com 2.

PS ENGINEERING has revolutionized audio control in general aviation airplanes. At that time, the original PMA6000 took the audio panel from a collection of switches added as an afterthought, to a multitalented intersystem focal point for cockpit audio.

Radio selection, cockpit communications and even music were seamlessly combined in the modern audio control panel. The PMA6000-series set a benchmark for all GA audio panels that followed.

The next generation PMA6000B benefits from PS Engineering's long experience of audio panel control design and manufacturing experiences. It is an excellent low cost audio panel alternative to the higher end systems that PS Engineering has become so famous for. 

The PMA6000B combines an audio selector panel with a top-quality manually adjusted 4 place VOX mono intercom and a slew of features to enhance versatility and utility. The PMA6000B holds both FAA TSO as well as EASA ETSO and was designed to be made easier to install because of a single 44-pin Sub-d connector. Different PMA6000B models offered with or without marker beacon receiver.

Built-in 4 place mono intercom PS Engineering's ""Set-it and Forget-it"" manual VOX

Optional built-in marker beacon receiver
