The PCU-1 microphone is a sturdy gooseneck desktop microphone with a talk button. PCU stands for "Paging Control Unit". The microphone amplifier with dynamic compressor is used to control the radio system in order to make a voice announcement via the control center.

An integrated codec with dynamic compressor suppresses interference factors and amplifies the signal of the voice announcement. 

The PCU-1 is the successor of the MIKO-23 and offers the advantage that audio lines are no longer required between the microphone and the radio system. The transmission is done via a USB interface.
