Designed to be pin-compatible with the popular Bendix/King KMA-24 audio selector panel, the PMA6000 takes advantage of existing wiring to smooth installation. Built-in 6 place mono intercom provides synergistic capabilities. The PMA6000 has a built-in marker beacon receiver. Split mode allows the pilot and copilot to independently and simultaneously use both radios, even transmitting simultaneously on different frequencies. Pilot and crew/passenger isolate functions are an integral part of the design. With split music inputs, front-seaters can bop to Thelonius Monk while the back jams on British Punk.

Dual music input jacks for passengers and crew are standard feature. Independent volume and squelch controls for pilot and copilot are standard. PSE's renowned Soft Mute technology gently and subtly ramps the music down when conversation comes across either the intercom or the radio. A patented "swap" function (Patent #5,903,227) allows pilots to use a yoke-mounted switch to select Com 1 and Com 2 options without reaching for the panel. High quality, voice-activated circuitry and individual microphone channels form the heart of the intercom system. Passengers have their own voice and audio amplifiers. Backlit switches linked with a photo sensor carefully calibrates panel lighting to cockpit levels for all situations. Fail-safe feature automatically hard-wires the pilot to Com 1 in the case of an outage. A Digital Recorder is available as an option. This continuous loop digital recorder stores all aircraft radio activity on the selected transmit radio. Up to 1 minute/16 messages are stored.
