Engineering's Dimensional Sound technology impresses
prides in being considered the innovative leader in aircraft audio control
systems. Their engineers have once again demonstrated their commitment to
cockpit audio control enhancements. The PMA450 will improve radio communications
as well as usher in a new approach to the user interface control.
list of capabilities:
automatic VOX hi-fi stereo intercom
True Dimensional Sound simplifies listening to com radios at the same time
Bluetooth® capability that includes Caller ID, complete control of the

music distribution for pilot, copilot and passengers
intercom mode with special "Alternate Intercom Mode"
(Radio Active Mute) eliminates constant back ground noise from radio static
all new PMA450 brings to the pilot a new invention, thanks to the cooperative
efforts of the United States Air Force. What Air Force pilots know as
Multi-talker, we call IntelliAudio®.
A digital communications interface, IntelliAudio®
places Com 1 and Com 2 audio in various positions within the stereo headset,
making simultaneous radio signals sound as if they are coming from different
locations. Com 1 and Com 2 audio can be placed in 9 unique positions, making it
easier for the pilot to concentrate on the radio of choice while ignoring the
radio of lesser importance at the time. For example, the pilot can choose to pay
attention to ATC while ignoring ATIS, depending upon what is pertinent at the
Even though the PMA450 is the most advanced audio
panel yet, it is very easy to use. Access to the advanced capabilities as well
as initial audio panel setup is all accomplished by the pilot through just three
soft-keys and a graphic display interface. This approach is the ultimate
in intuitive operation, nearly eliminating the need for an operator's manual;
it's all on the screen.
The PMA450 IntelliVox® automatic VOX system,
invented by PS Engineering in 1997, provides both pilots and passengers with
intercom squelch control. By consensus of the GA community, IntelliVox®
“works like magic” and eliminates the need for any manual adjustments to the
Digital control of the hi-fi stereo audio system
allowed PS Engineering’s designers a tremendous amount of flexibility, ranging
from music distribution, volume control for just about every input, and the ability
to customize labeling of specialized switched input signals.
Another much sought-after capability is PMA450’s
Bluetooth® implementation. This wireless system connects various Bluetooth®
enabled devices, providing a seamless connection to entertainment and telephone
devices. The utility of using a phone comes into play when an IFR clearance is
required at an uncontrolled airfield. With the din of the engine(s) and radios
tuned and set, the phone can act as a third com for calling departure control.
The audio panel allows the pilot to make
personalized adjustments to just about any and all of the audio inputs going
into the audio panel; eliminating trips back to the avionics shop and providing
settings that are just right for the pilot. There is no need to hook-up to a
computer, saving time and money in the installation process.
In addition to the traditional Nav 1 and Nav 2
audio capabilities, The PMA450 offers three additional audio switched inputs
that can be named to represent exactly what those inputs are being used for. For
example, the pilot may want to be able to switch on and off audio annunciations
like GPS waypoint alerts, AOA alerts, or other types of selectable audio
With the increased popularity of mobile personal
electronic devices, such as tablets, PDAs, iPhones, and iPads, the PMA450 has a
built-in 10 Watt-USB charger. Never be stuck with a discharged personal mobile
device in the cockpit again!
The PMA450 is plug-and-play with the PMA8000 series
and the GARMIN® GMA340 so the amount of time to replace an existing system is
negligible, helping to further reduce the cost of upgrading.
List price for the PMA450 is $2,395
price for the PMA450 without Marker Beacon receiver $2,295
