PAC 45

Digital Audio Control with MultiTalker® Tames Critical Communications for Special Mission Pilots


For the special mission pilot, where hearing many radios all at the same time is part of the job, and differentiating specific radio calls is not an easy task. That is until now.

MultiTalker®, is a patented technology developed by the Wright Patterson Air Force and exclusively licensed to PS Engineering.

MultiTalker® has the capability that allows the special mission pilot to pay attention to the radio call that is important at any one instant in time. MultiTalker® allows the pilot to place 6 individual com radio traffic, up to nine unique positions within a stereo headsets.

The PAC45 is pin compatible with the NAT AMS series making upgrading replacing legacy systems easy. The only additional wiring required is to accommodate the stereo channels for MultiTalker™ operation and the various control heads, if required.

Many enhancements included in the PAC45 include a powerful headset audio amplifier, our high-performance IntelliVox® automatic VOX circuit for very loud environments and front panel selection of Push-To-Talk Intercom. Up to three control heads can be mounted in strategic locations while the Hub can be mounted directly to the pilot’s control heads or mounted remotely.

The ability to pre-record audio alerts makes this audio controller an integral tool to help hear alerts that may be drowned out by the din of the cockpit environment. There are no computers required to configure the PAC45 or to record the 3 audio alerts, it’s all done from the front panel

Using the PS Engineering Bezel Generator Application,  the bezel can be customized to suit perfectly each aircraft’s special mission avionics suite. For example, a bezel could read Com 1, Com 2, VHF 1, VHF 2, FM 1, FM 2 and all of the various switched inputs can also be labeled accordingly. Ordering new decals for the bezel is as easy as using this bezel labeling configuration application.
