Telex Airman 750 GA Headset
The Telex Airman 750 GA headset is a lightweight, general aviation headset complete with boom-mounted, noise canceling electret microphone.
The Airman 750 is approved for aircraft use under FAA TSO C57a and C58a.
The headset features open-air style earphones for long-term, fatigue-free usage. The earphone housings are mounted on stainless steel sliders which permit over two (2) inches (55mm) of fitting adjustment. The ear cushions are removable for easy field replacement.
The Airman 750 headset features a miniature, amplified, noise-cancelling electret microphone that provides superior 400Hz hum rejection. The microphone boom is flexible for optimum microphone placement, and it is reversible for wearing either side of the head.
For best results the microphone should be positioned as close to the mouth as possible. A position at one side of the mouth is best to minimize popping, hissing and breathing sounds when speaking.
The microphone amplifier, contained in the boom-side earphone housing, has an adjustable gain control and provides output levels equivalent to carbon microphone levels.
