PS Engineering PMA8000 Series Audio Selector Panel and Intercom System Installation and Operator’s Manual Section I GENERAL INFORMATION 1.1 INTRODUCTION The PMA8000 represents another evolutionary step in cockpit audio control and intercommunications utility. Using our patented IntelliVox® design, this unit eliminates the requirements for intercom squelch adjustments. The unit is designed for outstanding ergonomics and visually defined mode annunciation and selection.
PS Engineering PMA8000 Series Audio Selector Panel and Intercom System Installation and Operator’s Manual controls the intercom level for the pilot and copilot, while the large knob controls the passenger intercom volume. Intercom squelch is automatic. A 3-light Marker Beacon receiver is integrated in the PMA8000. This provides the necessary Marker Beacon lights and audio indications necessary for an Instrument Landing System (ILS) approach.
