Audio interface modules

An Integrus DCN interface module is required if the transmitter is to be used with the DCN
Conference System. The module must be mounted inside the transmitter housing (see section
5.2 ).

Interface module slot - An optional audio interface module can be mounted in the
transmitter housing. Its connectors are accessible via an opening at the back of the
transmitter.
Emergency switch connector - A terminal block socket for a single, 'normally open'
switch. When the switch is closed, the audio signal on the Aux-right input is distributed
on all output channels, overriding all other audio inputs. A matching cable connector is
provided. The emergency contact does not function when the network mode of the
transmitter is enabled (see section 7.2.3 ) and it cannot connect to the optical network
(e.g. because the control unit of the DCN Next Generation conference system is
switched off).
Auxiliary audio inputs - Two female XLR connectors for extra audio inputs. They can be
used to connect auxiliary symmetrical audio signals such as a music installation, the
floor language or emergency messages.
Audio signal inputs - 4, 8, 16 or 32 cinch plugs to connect external asymmetrical audio
input signals. The number of connectors depends on the transmitter type.
Earth connection point - Only used for factory testing purposes.
Radiator signal loop-through input - A HF BNC connector to loop-through the radiator
output of another transmitter.
Radiator signal outputs - Six HF BNC connectors, used to connect the radiators. Up to
30 radiators can be loop-through connected to each output.
Optical network connections - Two connections used to connect directly to the DCN
Next Generation conference system with an optical network cable.
Mains input - Euro mains socket. The transmitter has automatic mains voltage selection.
A mains cable is provided
