The PCD7100 series, from PS Engineering, is an integrated Intercom and CD player designed specifically for aircraft installations. The PCD7100 incorporates PS Engineerings exclusive IntelliVox™, automating the digitally controlled intercom squelch. The PCD7100 has music and intercom volume controls for adjustment of the audio levels. The five back-lit CD push button controls that have LED mode annunciation are Play/Pause, Skip, Repeat, Stop and Eject.

In ISO mode, the pilot hears only aircraft radio traffic, without music or intercom interruptions. In crew mode, the pilot and copilot hear the internal CD player and radio traffic. An automatic fail-safe feature (EMG) connects the pilot directly to the aircraft radios if power is removed from the PCD7100 for any reason. Both the pilot and copilot have transmit capability over the aircraft radios. In ALL mode, all intercom positions hear the aircraft radios and the CD Player, with PS Engineerings proprietary SoftMute™ circuit.
