3 System Overview
The DCN System is a system for wired and wireless distribution and processing of audio
signals. The system can also be used for voting and simultaneous interpretation.
The DCN System is composed of three parts: the DCN network, the wireless network and the
optical network.
Figure 3.1 DCN System system overview
The DCN System comprises:
– Central control units, audio expanders, Integrus transmitter and/or wireless access
point.
– Wireless discussion units, wired discussion units, Consentus units, flush mounted units
and/or interpreter desks.
– Installation devices, such as Dual Delegate Interfaces (DDI) and extension power supply
units, trunk splitters.
NOTICE!
Refer to the Integrus manual for all related information.

3.1 DCN-CCU2 and DCN-CCUB2 Central Control Units
The Central Control Unit controls the system. The Central Control Unit can operate with or
without a control PC.
Figure 3.2 Front and rear view of CCU2
The front of the central control unit contains:
1. On/off switch - Power on or off the central control unit.
2. Display - Shows the configuration menu.
3. Knob - Operates the configuration menu and the volume level of the system.
4. Headphones socket - Headphone connection.
The rear of the central control unit contains:
5. Audio inputs - Connect the central control unit to external analog audio sources. The
functions of the audio inputs are:
– Audio input 1: Floor
Audio input 2: Selectable recorder/delegate loudspeaker/ mix-minus/insertion.
Interpreter floor insertion/local floor.
6. Audio outputs - Connect the central control unit to external analog audio devices. The
functions of the audio outputs are:
– Audio output 1: PA
Audio output 2: Selectable recorder/delegate loudspeaker/ mix-minus/insertion.
Interpreter floor insertion/local floor.
7. Power inlet - Connects the central control unit to the mains power supply with a power
cable.
8. Ground screw - Connects the central control unit to ground.
9. Fuse holder - Prevents damage to the internal power supply unit of the central control
unit.
10. Ethernet socket - Connects the central control unit (DCN-CCU2) to the PC, remote
controller or in a multi CCU system to the master central control unit.
11. RS232 - Connects video cameras to the central control unit.

12. Fault contact - Connects the central control unit to devices to sense the condition of the
central control unit.
13. DCN sockets with cable locking facility - Connects the central control unit to the DCN.
14. Ground lift - Default: grounded. Do not ground more than one mains powered device to
prevent humming sound caused by ground loops.
15. Optical network sockets - Connects the central control unit to the optical network.
The DCN-CCUB2 Basic Central Control Unit controls the system. The basic central control unit
is a simplified version of the DCN-CCU2 Central Control Unit. The DCN-CCUB2 Basic Central
Control Unit:
– Has one XLR output.
– Does not have any XLR inputs.
– Does not have a fault contact.
– Cannot be connected to the optical network Controls, connectors and indicators.

3.1.1 Audio I/O routing
Recorder
The Recorder mode is the default audio I/O routing mode. In the Recorder mode, audio output
2 of the central control unit transmits a signal that can be connected to an external audio
recorder. The central control unit has no effect on the volume level of the signal.
In the Recorder mode, the audio input 2 signal of the central control unit is added to the floor
signal.

Insertion
In the Insertion mode, audio output 2 and audio input 2 of the central control unit are both
used to add signals from external audio devices. For example, connection of an external audio
mixer between audio output 2 and audio input 2 of the central control unit.

NOTICE!
In the Insertion mode, a device between audio output 2 and audio input 2 of the central
control unit could be connected. When no device is connected, the audio signals from
contribution devices (floor) leave the system, but do not enter the system again.

Interpreter floor insertion
Interpreter Floor Insertion is used in applications where interpreters have video screens to
view the conference room. In case the video signal has latency, the floor audio for the
interpreters, can be delayed with an external device to lip-sync it with the video plus improve
S/N ratio for systems with external floor and DCN interpretation Integrus. The external device
should be connected to output 2 and input 2.
Figure 3.7 Interpreter floor insertion
Local floor in Multi-CCU sytems
Local floor is applicable only for slave CCUs and is used to create directional sound. In the
Local floor mode, audio output 2 of the central control unit only transmits the floor signal of
the units connected to the DCN-CCU2. In this way audio outputs 2 of the slave CCUs can be
connected to multiple external public address system.
