Conference system central control unit.

The MCMU 100 conference system provides a system of speech intelligibility and listening to meeting participants through the amplification and distribution of sound, as well as to promote and conduct an orderly and disciplined discussion. Participants can control their own microphones, although a chairperson has priority functionality that allows control of other participants who may be speaking. The system is made up of MCMU 100 (central unit), MCM 10C (chair microphone) and MCM 10D (delegate microphone). The microphones are sold separately.
