3 Connecting to an Integrus transmitter

3.1 Connecting interpreters desks LBB 3222/0x directly

An Integrus transmitter requires the LBB 3422/1x Symmetrical audio input and interpreters module to directly interface with
one or more LBB 3222/0x interpreter desks. This module must be mounted in the transmitter housing (see the Integrus
installation manual).
Up to 12 interpreter desks can be loop-through connected to the module. The system cable of the first interpreter desk is
connected to the 25-pole sub-D connector on symmetrical audio input and interpreters module. The system cables of the next
desks are loop-through connected to the system input plugs on the preceding desks.
The floor signal for the interpreters desk is connected to the Aux-Left input of the Integrus transmitter with an XLR connector.
The floor signal can come from a CCS 800 analogue conference system (i.e. the line output cinch connector, see the CCS 800
installation manual) or from an external audio source, such as an audio mixer.
The DIL switches on the symmetrical audio input and interpreters module must be set to 'Direct connection to LBB 3222/0x
interpreter desks' (see section 2.2).
The 'Aux. Input' mode of the Integrus transmitter must be set to 'Emergency/Mono' (see the Integrus installation manual).
Note: To connect the floor signal, a cable with a male XLR connector and a male cinch connector must be made. See Figure 3.1 and
Figure 3.2 for the wiring.
