2 Integrus audio input
and interpreters module
(LBB 3422/20)
2.1 Introduction
An Integrus audio input and interpreters module is
required when an Integrus transmitter is to be used for
direct connection of interpreters desks LBB 3222/04
(in combination with e.g. the CCS 800 system) or with
analogue conference systems (such as the CCS 400).
The interface module must be mounted in the trans-
mitter housing.
Figure 2.1:
1. Interface connector – A 25-pole sub-D female
connector for direct connection of up to 12 LBB
3222/04 interpreters desks or analogue conference
systems with interpretation.
2. Positions for input transformers – Eight input
transformers can be mounted for galvanic separa-
tion of source and electronics inputs. The eight
Integrus audio inputs at the 25-pole D-type plug
can be isolated by adding eight audio transformers
(Beyer type TR/BV3) in these positions.
3. Function switches – Three DIL switches for deter-
mining module functionality.
4. PCB connector - A 55-pins connector that con-
nects the module to the Integrus transmitter’s main
PCB.
5. Mounting plate.
