PMA7000M-S Series Audio Selector Panel and Intercom System
Installation and Operator’s Manual
200-070-0012 Page 1-2 Rev. 12, Sept. 2000
A six-station voice activated (VOX) intercom is included in the PMA7000M-S. This system has PS Engi-
neering’s exclusive IntelliVox® circuitry that eliminates manual adjustments. The system contains six sepa-
rate VOX mic circuits, and only opens the microphone channel in use.
The intercom system incorporates pilot isolate and crew modes, two stereo music inputs with "Soft Mute,"
and LED indicators for swap and transmit indications. Intercom control is through front panel-mounted
knob and 3 position mode switch. A single volume controls intercom level for the pilot and copilot. Passen-
ger headphone volume is factory set, and adjusted in flight with headset-mounted volume controls. Passen-
ger volume control is further adjustable through screwdriver access in the top of the unit. Intercom squelch
is automatic.
An optional 3-light Marker Beacon receiver is integrated in the PMA7000M-S. This provides the necessary
Marker Beacon lights and audio indications necessary for an Instrument Landing System (ILS) approach.
