Section I GENERAL INFORMATION
1.1 INTRODUCTION
The PAC24 represents the finest in high-performance cockpit audio control and intercommunications.
Using proprietary IntelliVox® design, this unit eliminates the requirements for intercom squelch adjust-
ments. The unit is designed for outstanding ergonomics and visually defined mode annunciation and se-
lection.
The PAC24 was designed to be a dual audio panel, offering convenience and utility for two-pilot crews, in
installations where a single panel is not practical.
The PAC24 –0500 is available where a vertical orientation would be appropriate.
Before installing and/or using this product, please read this manual completely. This will ensure that you
will take full advantage of all the advanced features in the PAC24.

The PAC24-series is a state of the art audio isolation amplifier and audio selector that contains an auto-
matic voice activated (VOX) intercom system. It can switch up to five transceivers (Com 1, Com 2 Com 3
Com 4 and Com 5) and 4 receivers (Nav 1, Nav 2, AUX (or ADF in –0500, -0503) and MKR).
The Duplex Telephone mode allows the PAC24 to act as an audio interface between aircraft headphone
and microphones and specific aircraft approved (FAA/FCC) cellular telephone equipment.
Warning: Use of non-aviation approved cellular telephone equipment may be prohibited by regulation.
PS Engineering is not responsible for unauthorized airborne use of cellular telephones.
For airborne use, the PAC24 must be interfaced with an approved system.
There are two unswitched inputs, for autopilot disconnect, and/or radar altimeter warning. Push buttons
select the receiver audio source provided to the headphones. A SPR switch allows the user to listen to the
receiver(s) selected on the cabin speaker. Except for the unswitched inputs, all speaker audio is muted
during transmit.
