1.1.1 General Description
The Telex Airman 750 Headset and the Airman 760 Headphone are designed and engineered for
high-quality aircraft communications. The Airman 750 is approved for aircraft use under the Federal
Aviation Agency TSO C57a and C58a. The Airman 760 is approved for aircraft use under the
Federal Aviation Agency TSO C57a.
The Airman 750 Headset features a miniature, noise-canceling electret microphone element which
provides superior hum rejection. The microphone is mounted upon a boom which pivots 310 degrees
for use on either side of the user's head. The headset amplifier has an adjustable gain control and
provides output levels equivalent to carbon microphone levels. Several variations of the 750 headset
exist; each model has a different connector and a unique wiring diagram.
The Airman 760 Headphone is designed for users who operate hand-held microphones. The 760 is
virtually identical to the 750 headset, without the boom microphone.
