The Telex 66T and 66TRA Hand Mics are high quality, dynamic, handheld microphones offering superior noise cancellation and voice response in durable casements.

With built-in solid state amplifier, the 66 series microphones adjust for proper transmitter modulation.

Noise Cancellation
The 66T microphone provides excellent noise cancellation and speech intelligibility in moderate noise environments. The microphone discriminates against all sounds more than 1/2-inch away.

Microphone
The microphone is gain adjustable through an opening in the back of the microphone using a small, flat-blade screwdriver. The microphone is supplied with an adhesive label which may be placed over this opening after adjustment to prevent tampering.

Versions Available
The model 66TRA is also available which features a molded right-angle plug. All other aspects of the microphone are the same as the 66T.

FAA TSO Approval
The 66T and 66TRA microphones are approved for aviation use under FAA TSO C58.
