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.
