BOSCH CCSD-CU Control unit
The Control Unit is the main component of the CCS1000 Digital Discussion System. It supplies DC power to all connected Discussion Devices and monitors and controls the discussion system. Touch‑button control allows for easy configuration and operation of the unit, while intuitive LED indicators give a clear indication of the system settings. Conveniently positioned connections at the rear of the unit enable peripheral equipment to be connected to the discussion system, such as audio equipment and Bosch HD Conference Domes. Intuitive web browser control allows basic and advanced system settings to be easily viewed and changed, as required. Two types of Control Unit are available:
• the CCSD-CU, and
• the CCSD-CURD that has additional features such as
MP3 recording and Digital Acoustic Feedback Suppression (DAFS). The four RCA outputs at the rear of the CCSD-CURD ensure that the unit is optimized for use in courtrooms, i.e. for the recording of individual speakers.
