38T
Noise Cancellation
- The 38T cancels noise best when held very close to the mouth, and it discriminates against all sounds more than ½-inch away. A position at one side of the mouth is best to minimize popping, hissing and breathing sounds when speaking.
Microphone Gain Adjustment
- The gain is adjustable through an opening in the side of the microphone housing using a small, flat-blade screwdriver. Clockwise rotation of the control increases gain. Adjustment by a qualified avionics technician is recommended, as excessive gain can cause transmitter overload distortion.
FAA TSO Approval
- The 38T microphone is certified for aviation use under FAA TSO C58.
