*The figure stated represents the number of units rated with a Power Consumption Factor (PCF) of

1.For further information regarding the Power Consumption Factor refer to Chapter 10.1.1: “System design fundamentals”.

The unit’s built-in functions include:

Power supply to supply up to a maximum of 90 PCF points

Control facilities for controlling up to 240 contribution units

Digital audio control and processing facilities for 2 x 15 HiQ digital audio channels, used for contribution, distribution and interpretation units

4.4LBB 3500/35, LBB 3500/35(D) 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.

When the CCU is set to the Multi CCU system mode, a dedicated PC must be connected which acts as the master to all slave Multi-CCU’s connected. This PC must be fitted with a Multi-CCU PC card type LBB 3511/00 and Multi-CCU software type LBB 3586 (see Chapter 5.4).

The unit’s built-in functions for the Multi-CCU system mode include: (see also Chapter 4.6).

NOTE: For Control and Indicators see Chapter 4.4 and FIG 4-2

As for the LBB 3500/15 but includes:

• Up to 16 Multi-CCUs can be connected, allowing in total up to 3840 (max.) active DCN units to

 

be connected, or up to 7680* microphones to be connected using Dual Audio Interface units

 

LBB 3535/00.

 

NOTE: * The delegate database can only contain 1500 records.

 

• Switchable between Single and Multi-CCU mode.

 

• Two basic microphone Operational modes (Operation) including:

 

(1) ‘Open’: Microphone key-control with request-to-speak registration

 

(2) ‘Override’: Microphone key-control with override (First-In-First-Out)

 

Each mode of Microphone operation allows the selection of 1, 2 or 4 microphones to be

 

switched on concurrently.

 

NOTE: When set to Single system mode, the Multi-CCU’s built-in functions are identical to

 

those of the Extended CCU, type LBB 3500/15.
