The Bosch CCS Control Unit is the central power and control station for all CCS 900 Ultro Conference System contributor units, such as the chairman and delegate units. The control unit will supply power for up to 50 delegate / chairman units, and provide control for up to 150. The unit features a built in speaker and automated, programmable control over contributor units without the need for an operator. Plenty of connections allow for interfacing within paging systems, amplifier systems, recording devices and more. The unit is feature rich, however its control section is straightforward and intuitive to operate in any conference setting.
