Ob Du das nun glaubst, oder nicht: Tatsächlich kann das PMA450B das Audio räumlich ausgeben.

Dimensional Audio

Just like early versions of the PMA450, the current one has PS Engineering’s IntelliAudio. The tech is licensed from the U.S. Air Force, which developed the function as an intuitive way to process headphone audio after recognizing its pilots are inundated with multiple audio signals at once.

When it’s turned on in the PMA450B (accessed from the lowest line select key) comm radio audio signals are digitally processed to appear in different locations in the headset. Maybe you want ATIS or approach control from the second radio positioned at the 3 o’clock position and the primary radio at 9 o’clock. When in Auto mode, IntelliAudio reverts to normal when one of the radios goes quiet, and separation returns when both are active. The HRTF (head related transfer function) allows the user to relocate each comm radio to one of nine defined locations using a simple onscreen graphic that shows where each radio will play. You’ll need stereo headphones for the function to work, and intercom audio cannot be spatially adjusted—a good thing, in our view, for the sake of simplicity. The function can be turned off entirely.
