Example 1 - basic discussion system
This is a straightforward situation, where a discussion
requires the order and convenience of DCN but only
the most basic of hardware. All delegates speak the
same language, so there is no need for interpretation.
Subsequently no headphones are required, as all dele-
gates receive the same audio signal (the speaker), which
is transmitted via loudspeakers.
Each delegate has exactly the same status, and is provid-
ed with the same equipment; an LBB 3530/00 Standard
Delegate Discussion Unit.

Chairman
Discussion Unit
The chairman has a LBB 3533/00 Chairman Discussion
Unit which allows him or her to override all other dele-
gates. This allows them to speak, listen to the speaker
and register a request to speak.
All contribution equipment is connected to the
LBB 3500/05 Basic Central Control Unit. This CCU
supplies power to all delegate units, provides audio
equalisation for all delegate loudspeakers, and is used to
determine the microphone operating mode. No opera-
tor is required.
