DCN Interface Module (LBB 3423/00)

A 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 housing (see section 2.2.2).
Figure 2.4 DCN Interface Module
1. DCN output connector – A 6-pole trunk output female DIN connector for loop-through interconnection 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
When the DCN system supply voltage on the trunk input switches off, the DCN Interface Module automatically switches the
transmitter to standby. When the DCN system supply voltage switches on, the transmitter is switched to operating mode.
: When the DCN interface is used in combination with audio signals connected to the cinch inputs, the DCN and audio signals on
corresponding inputs are mixed.
