The MCU-2A/P variant featured an internal M101/AIC microphone that connected to a female jack which was used with the U-137/U type male audio plugs. This style of voice emitter was used on many masks produced by the United States such as the XM-44 and M42.

With the MCU-2A/P Gas Mask, an internal microphone could be placed inside the mask and connected to an external communications system through the connector on the front voice emitter. However, field experience and testing in the late 1990s showed that the microphone connector assembly represented a damage failure point on an unacceptable number of MCU-2A/P masks. Since changes in technology provided external mask communications capabilities that no longer required a connector assembly, it was decided to discontinue the MCU-2A/P. All further production reverted to MCU-2/P masks.
