the ability to place 6 different com audios in up to 9 unique positions
within a stereo headset, a whole new way of discerning important radio
traffic is now available to the special mission pilot.
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™, a patented technology developed by the Wright Patterson Air Force
exclusively licensed to PS
Engineering, allows the pilot (and crew) to take advantage of what is sometimes
referred to as
the "Cocktail Party Effect". In a room
crowded with many different conversations, our brain has the ability to filter
out the un-important conversations while allowing pilots to pay attention to the
conversation that is.
MultiTalker™ offers this unique capability to the
special mission pilot, the ability 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
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
Many enhancements included in the PAC45 include a powerful headset audio amplifier,
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.
Because this is an all digital audio controller, the
connections to the various control heads are just a few wires, eliminating the
need to parallel radio inputs and outputs.
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
The stereo audio amplifiers are capable of providing 100 milliwatts (mW) into general aviation
headphones. According to PS Engineering's founder and president, “We asked helicopter
pilots what they needed, they said they wanted more audio punch to get through the cockpit
noise and an easy to use interface". The PAC45 delivers on all fronts.
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.

helmets be used. Carbon microphones or equivalent must be used. If using
military 8 ohm microphones, an adapter is required.
