2.3 Connections
This chapter gives an overview of typical system
connections using the INT-TX range transmitter:
• Connecting the DCN Next Generation system
• Connecting the DCN system
• Connecting other external audio sources
• Connecting an emergency signal switch
• Connecting to another transmitter
2.3.1 Connecting the DCN Next Generation
The transmitter can be directly connected to the opti-
cal network of the DCN Next Generation conference
system. Use an optical network cable to connect one
of the optical network sockets of the transmitter to the
optical network (see figure 2.11). The network mode
must be enabled with the configuration menu (see
section 2.5.8).
2.3.2 Connecting the DCN system
The transmitter requires the Integrus DCN Interface
Module (LBB 3423/20) to interface with the Digital
Congress Network (DCN). This module must be
mounted in the transmitter housing (see section 2.2.2).
The connections between DCN units and the transmit-
ter are made in a loop-through configuration via the
DCN 6-pole circular connectors on the module’s rear
panel. See the DCN Installation and Operating
Manual for more information.
2.3.3 Connecting other external audio
sources
The transmitter has up to 32 audio inputs (depending
on the transmitter type) to interface with external
asymmetrical audio sources, such as congress systems
from other manufacturers or for music distribution.
The audio signals (stereo or mono) are connected to
the audio input cinch connectors.
Note: See the DCN Next Generation
Installation and User Instructions for
more information about connecting the
transmitter in the optical network.

Note: When the cinch audio inputs are used
in combination with inputs via one of the
interface modules, the signals on corre-
sponding channels are mixed. This situa-
tion should normally be avoided by using
higher-numbered cinch audio inputs.
