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.
