Wired or wireless language distribution
DCN offers a choice of language distribution systems.
Language distribution can be carried out using the
DCN system cabling, and languages are accessed and
selected by means of channel selector units or delegate
units with built-in channel selection facilities. There is
also a wireless, digital infra-red system, Integrus, where
the languages are distributed throughout the conference
venue by infra-red transmitters and radiators, and
accessed by means of personal infra-red receivers with
headphones.
1.4 Central control equipment
The Central Control Unit (CCU) forms the heart of the
congress management system. The CCU can operate
stand-alone to provide automatic conference control,
or be accessed by an operator via a PC when more
extensive management is required.
All CCUs can control up to 240 contribution units,
such as delegate and chairman units, interpreter desks
and audio interface units. If more capacity is required,
Multi-CCUs can be connected, each of which increases
the system capacity by 240 contribution units. CCUs
can power a number of contribution units. The maxi-
mum number depends on the type of CCU, and the
type of contributiion units used in the application.
DCN Data Brochure
Fully-automatic conference proceedings
The basic CCU does not require operator control, and
automatically manages conference proceedings. It offers
basic microphone management, simultaneous interpre-
tation and electronic voting facilities, as well as 15 Hi-Q
digital audio channels, ten data channels and four com-
munication channels. This allows effective unsuper-
vised control of even large, international conferences.
Operator control via a PC
The extended CCU offers all the facilities of the basic
model, but also allows operator control via a PC. The
user can access the extensive family of DCN software
modules, each with a specific function in controlling
and monitoring conferences.
This includes advanced simultaneous interpretation
and microphone management, message generation and
display, six kinds of voting, intercom, creating a dele-
gate database, attendance registration. In the event of
PC failure this CCU will revert to a default operation
mode, identical to that of the basic CCU, thus enabling
conference proceedings to continue.
