The PMA450B is the second generation digitally based audio panel that is based upon a DSP (Digital Signal Processor). Licensed patented technology from the United States Air Force that was designed for the fighter pilot, who is inundated with multiple audio signals, is now available to the GA pilots.

Another leap forward is PS Engineering’s improved and unique graphical user interface. Using OLED technology, the larger display is easier to read from any angle and lighting conditions.

The new USB – C standard also brings more power to the pilot. This USB port is for powering devices up to 15 Watts, 33 % more power than was available before.

IntelliAudio® gives the pilot the capability to pay attention to the radio that is important to their flight at any one instant in time. Consider Com 1 coming from the 10 o’clock position while Com 2 is coming from the 2 o’clock position, just like being at a cocktail party, you are able to pay attention to the person who is telling you something important while ignoring the other conversations that aren’t.

The 3 Soft-key user interface is unprecedented for audio control panels. With more and more capability provided by our audio panels, we found it necessary to make the access to these functions easier. If you can read English  you’ll be able to get all of the capability from the PMA450B without ever having to open up the User’s Guide.

A new option for the PMA450B is the PS Streamer™. This system will steam selected audio to external, Bluetooth® enable devices, such as ProGo® cameras or other audio dongles. 

This audio panel is plug ‘n play with GARMIN’s GMA340, which makes upgrading as easy as 1-2-3. The existing wire harness and tray that is installed for the GMA340 is complete and there is nothing to add or change. Get all of the new capabilities by simply removing and replacing. A simple log book entry is all that is required.
