3. Auxiliary audio inputs – Two female XLR con-
nectors for extra audio inputs. They can be used to
connect auxiliary symmetrical audio signals such as
a music installation, the floor language or emer-
gency messages.
4. Audio signal inputs – 4, 8, 16 or 32 cinch plugs to
connect external asymmetrical audio input signals.
The number of connectors depends on the trans-
mitter type.
5. Earth connection point – Only used for factory
testing purposes.
6. Radiator signal loop-through input – A HF BNC
connector to loop-through the radiator output of
another transmitter.
7. Radiator signal outputs – Six HF BNC connec-
tors, used to connect the radiators. Up to 30 radia-
tors can be loop-through connected to each output.
8. Optical network connections – Two connections
used to connect directly to the DCN Next
Generation conference system with an optical
network cable.
9. Mains input – Euro mains socket. The transmitter
has automatic mains voltage selection. A mains
cable is provided.
2.2 Audio interface modules
2.2.1 Integrus DCN interface module
An Integrus DCN interface module is required if the
transmitter is to be used with the DCN Conference
System.
The module must be mounted in the transmitter hous-
ing (see section 2.2.2).
Figure 2.4:
1. DCN output connector – A 6-pole trunk output
female DIN connector for loop-through intercon-
nection with DCN units.
2. DCN input cable – A 2 m (6 ft 6 in) trunk input
cable with 6-pole male DIN connector for loop-
through interconnection with DCN units.
3. PCB connector
4. Mounting plate
When the DCN system supply voltage on the trunk
input switches off, the Integrus DCN interface module
automatically switches the transmitter to standby.
When the DCN system supply voltage switches on, the
transmitter is switched to operating mode.

Note: When the Integrus DCN interface
module is used in combination with audio
signals connected to the cinch inputs, the
DCN and audio signals on corresponding
inputs are mixed.
