3.2 Connecting interpreters desks LBB 3222/0x via the CCS 400 system

An Integrus transmitter requires the LBB 3422/1x symmetrical audio input and interpreters module to interface with the CCS
400 discussion and interpretation system. This module must be mounted in the transmitter housing (see the Integrus installation
manual).
The CCS 400 system is connected to the symmetrical audio input and interpreters module by means of a 25-pole sub-D
connecting cable. The interpreters desks and the floor signal are connected to the CCS 400 system. See the CCS 400 installation
manual for more information.
Note: Before connecting the CCS 400 analogue conference systems, the DIL switches on the symmetrical audio input and interpreters
module must be set to 'Connection to other audio sources'. For details of the required settings, see section 2.2.

3.3 Connecting other analogue conference systems

An Integrus transmitter requires the LBB 3422/1x symmetrical audio input and interpreters module to interface with other
analogue conference systems. This module must be mounted in the transmitter housing (see the Integrus installation manual).
The analogue conference systems are connected directly to the symmetrical audio input and interpreters module by means of a
25-pole sub-D connecting cable. For pinning information see chapter 4.
It is also possible to connect a conference system directly to the asymmetrical audio cinch inputs of an Integrus transmitter. In
that case the interface module is not necessary.
Notes:
•
Before connecting other analogue conference systems, the DIL switches on the symmetrical audio input and interpreters module must be
set to 'Connection to other audio sources'. For details of the required settings, see section 2.2.
•
If galvanic separation is required, add Beyer type TR/BV3 audio transformers on the module's PCB (see section 2.1).
