Overview
- For DCN Next Generation or DCN wireless systems, or a combination of the two
- In single‑CCU; maximum 245 wired contribution units, plus 245 wireless delegate units
- For multi‑CCU systems, with up to 30 CCU’s and a total of 4000 contribution units
- Voice activated microphone mode for wired and wireless systems
- Ethernet connection for configuration and control computers
the Bosch DCN-CCU2 is a Central Control Unit (CCU) with 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.
This new and improved control unit allows a maximum of 25 open microphones while the older CCU only allowed for up to four open microphones. With the DCN-CCU2, you can also mix and match a wired and wireless systems and distribute of up to 10 language channels plus floor to DCN wireless discussion units (maximum one DCN‑WAP per system). It has also an Ethernet connection for Control PC, Open Interface or slave CCU.
The CCU2 improves upon the control capabilities of the basic central control unit DCN-CCUB2. For example, the CCU2 optical network enables language distribution using wired microph9ones (thru channel selector). The optical network alllows a connection to I-desks, a transmitter and audio expanders. The CCU2 also supports multi CCU functions.
