PS Engineering announcing the PMA450
IntelliAudio®, a digital communications interface, provides the ability to place sounds in various dimensions within the crew's stereo headset. IntelliAudio® allows placement of Com 1 and Com 2 in any position designated by a Blue Dot, within the stereo headset. This makes simultaneous radio signals appear to come from different locations. Com 1 and Com 2 audio can be placed in 9 unique positions, allowing the pilot to configure the placement so that they can best concentrate on the radio of choice while ignoring the radio that's unimportant at the time.
