DCN Concentus Units

Standard Delegate Unit

The LBB 3544 is the basic Concentus
delegate unit, enabling delegates to speak,
register a request-to speak, register a
response request, listen to the speaker and vote. The flat-panel
loudspeaker offers superior acoustics with minimal feedback, so
increasing intelligibility. It is automatically muted when the
microphone is activated. When the unit is not being used, the
loudspeaker panel conveniently folds down. There are five voting
buttons for parliamentary, multiple choice or audience response
voting.
