The Modified Microphone M-169A/AIC is a noise-cancelling moving coil microphone element designed for use in an oxygen mask or pressure helmet at altitudes where the use of oxygen is required.

The M-169A/AIC microphone was designed to replace the M-101/AIC in most applications providing more accurate placement within the masks and considerably better intelligibility and noise rejection.

The M-169A/AIC microphone incorporates stateof-the-art adjustment and placement system that provides exceptional stability for the microphone element. It is manufactured to the latest revision of Military Specification, MIL-PRF-26542/120.

The M-169A/AIC was developed specially for the HA/LP®, MBU-20/P and MBU-20A/P oxygen masks.
