Central Equipment
The Central Control Unit DCN‑CCU2 or DCN‑CCUB2 forms
the heart of the conference management system. Both
CCUs can operate standalone to provide automatic
conference control, or be accessed by an operator via a
PC when more extensive management is required.
In combination with the DCN‑WAP, the DCN‑CCU2 also
forms the heart of a DCN Wireless system, or wireless
flexibility can be added to a wired DCN Next Generation
system for temporary system expansion.
The DCN‑CCU2 can control up to 245 wired contribution
units (such as delegate and chairman units, interpreter
desks) and up to 245 wireless discussion units. If more
capacity is required, multiple DCN‑CCU2s can be
connected to each other to control up to 4000
microphone positions.
The DCN‑CCUB2 can control up to 245 wired contribution
units and cannot be extended with wireless units or
multiple CCUs.
Both CCUs can also provide power for a number of
contribution units. The maximum number depends on the
type of contribution units used in the application.
Advanced audio coupling using the DCN‑CCU2
Via the optical network, a variety of audio couplings are
possible, including coupling small systems with a few
languages into a large system with as many as 31
languages.
It is also possible to extract and insert both digital (AES/
EBU or SPDIF) and analog audio. Other advanced audio
coupling techniques include CobraNet™.
CobraNet™ is a combination of software, hardware and
network protocol, which allows distribution of many real-
time, high-quality digital audio channels over an Ethernet
network using CAT5 cables.
CobraNet™ makes it easy to distribute audio in buildings
and connect the DCN system to other audio CobraNet™-
compatible devices such as Audio Recorders and Audio
Mixers.
