The beyerdynamic MCW-D 200 central control unit has the capability of controlling up to 65,000 digital wireless microphones. The system operates in the 2.4GHz band and uses direct sequence spread spectrum (DSSS) modulation to ensure noise immunity when used in conjunction with other 2.4GHz systems. The MCW-D 200 is used with the MCW-D 2073 wireless digital chairperson microphone unit and the MCW-D 2071 wireless digital delegate microphone unit.

The control unit can power up to 50 chairperson and delegate units and can control up to 150 discussion units. The system incorporates Bosch's Digital Acoustic Feedback Suppressor. The system also allows for multiple mics to be on simultaneously.
