CONTRIBUTION EQUIPMENT
2.1.2 Delegate unit
For use by delegates to actively participate in discussion/conference proceedings - ranging from small
discussion groups to multi-national conferences. Its basic functions allow delegates to speak, listen to
other participants, and to participate in voting sessions (conference units only) using the units voting
keys .
2.1.3 Chairman unit
For use by a chairman, the chairmans unit is similar to the delegate unit but includes a ‘priority button’.
This button when pressed temporarily mutes or permanently cancels all other microphone users. An
optional chime tone is available when the priority button is used. A system may have one or more
chairman units; for use by assigned delegates, privileged speakers or VIP’s etc. In permanent mode, all
delegates waiting to speak are also removed from the request-list. Chairman unit LBB 3547/00 has

as to cancel all delegates’ microphones and requests-to-speak.

2.1.4 ‘Microphone Only’ Function
A microphone ‘only’ function is for use by Podium and mobile floor speakers, or in installations where
no delegate units are used. DCNs range of microphones can be connected to a Dual Audio Interface
unit or a Multi-purpose connection unit. The Dual Audio Interface unit LBB 3535/00 can serve two
delegate positions.
2.1.5 Interpreter desk
For use in bi/multi-lingual discussions/conferences, the interpreter desks can handle up to 15 different
language channels in addition to the floor language. Up to six interpreter desks can be installed per
booth. Its design provides for efficient operation, and preselection of the incoming language. A back-
lit alphanumeric display shows the selected language in combination with a ‘quality indication’ (direct
or indirect interpretation). An ‘auto-relay’ facility enables interpreters to interpret from unfamiliar
languages, where the desk automatically transmits the relay language to all other interpreter desks for
onward interpretation.
