Bosch DCN‑CCU2 Central Control Unit

The Central Control Unit (CCU) includes features for controlling wired and wireless delegate microphones,
distributing simultaneous interpretation and conducting voting sessions, all without an operator. In combination with a PC, this control unit brings greater sophistication to conference control. Users can access an extensive range of software modules, each with a specific function in controlling and monitoring a conference. These modules greatly expand the capacity to manage a conference. In the event of PC failure, this control unit will revert to its stand-alone
operation mode, enabling the conference to proceed.
