Approval Basis; Specifications - PS Engineering PAC24 Installation And Operation Manual

A voice activated (VOX) intercom is included in the PAC24. This system has PS Engineering's exclusive
IntelliVox® circuitry that eliminates manual adjustments. The system contains six separate VOX mic cir-
cuits, and only opens the specific microphone channel in use.
The intercom system incorporates pilot isolate and crew modes, a monaural music input with "Soft Mute,"
and LED indicators transmit indications. Intercom control is through front panel-mounted knob and 3 po-
sition mode switch. A single volume controls intercom level for the pilot and copilot. Passenger headphone
volume is factory set, and adjusted in flight with headset-mounted volume controls. Passenger volume con-
trol is further adjustable through screwdriver access in the top of the unit. Intercom squelch is automatic.
The PAC24 is form fit and function compatible with the King Radio KMA24H, part number 066-1055-71,
and may be compatible with 066-1055-70.
