DCN‑CCU2 Central Control Unit

www.boschsecurity.com

u For DCN Next Generation or DCN wireless systems,

or a combination of the two

u In single‑CCU; maximum 245 wired contribution

units, plus 245 wireless delegate units

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.
