Multi Central Control Unit
The Multi-CCU LBB 3500/35 is functionally identical to the LBB 3500/15 Central Control Unit and is
used to extend the capacity of the DCN system when more than 240 contribution units are required.
Each subsequent slave CCU (max. 16) added, increases the system capacity by a further 240 units.
The unit can be used stand-alone and function as an LBB 3500/15 CCU. If the software package
installed allows, the ‘Single’ operating mode can be selected by means of a front-panel push-button
switch. The flexibility of the unit means that it can cater for virtually every conference requirement.
