LBB 3530 DCN Basic Delegate Unit	LBB 3531 DCN Basic Delegate Unit with Channel Selector	LBB 3533 DCN Basic Chairman Unit

The LBB3530 is the basic delegate discussion unit, enabling participants to speak, register a request to speak, and listen to the speaker. The microphone stem is extremely flexible, so the microphone can be used by delegates sitting on either side of the unit, thus allowing one unit to serve two delegates. The unit also accommodates two separate headphones, so the speaker can be heard clearly even in situations with excessive background noise. This aesthetically-pleasing unit has a built-in loudspeaker which is muted when the microphone is on to prevent acoustic feedback.	The LBB3531 is stylistically identical to the LBB3530 Basic Delegate Discussion Unit, but also includes a built-in language channel selector. This makes it suitable for discussions where more than one language is used and simultaneous interpretations are available. The channel selector includes up and down select keys and a 2-digit display, enabling rapid selection of the required language channel. Channel selection is automatically limited to the number of language channels available.	This stylish, compact chairman unit is equipped with facilities that enable the user to function as the chairman of a discussion. Stylistically identical to the LBB3530 Basic Delegate Discussion Unit, the LBB3533 also has a microphone priority button which, when pressed, causes all currently active delegate microphones to be permanently or temporarily switched off, (depending on settings in the CCU) thus allowing the chairman to take control of the meeting.

When used stand-alone, the built-in microprocessor is manually programmed to allocate language channels, channel routing and interlocks. In operator-controlled systems, the desk is used in combination with DCN dedicated software (and other interpreter desks) to form a completely integrated interpretation network.
