38T Electret handheld microphone by Telex


Electret handheld microphone

The Model 38T is a noise-canceling, hand-held aviation microphone. It consists of an electret microphone element, a microphone amplifier, and a push-to-talk switch enclosed in a rugged, black plastic housing. The 38T is extremely resistant to interference, hum, and squealing induced by 400Hz power systems. Also, the harsh switch popping common to other microphones has been eliminated in the 38T through the use of electronic switching. The 38T is approved under Federal Aviation Agency TSO-C58.
