 BOSCH/DCN
The DCN Congress brings a distinctive new look to digital congress management.
It combines top-quality acoustical performance and advanced functionality with ease of installation and groundbreaking design that adds elegance and prestige to any conference venue.
Extended Central Control Unit LBB 3500
The kind of discussion shown in this example is typical of a local council or board meeting, where some formalised structure is required and the need for quick and efficient decision taking means that an automatic voting system is required. This unit is used as a stand-alone conference control system, providing voting facilities as well as microphone management and power for all contribution units. The unit also has microphone priority and can be used to start, stop and suspend voting, and alter delegate microphone status. Each delegate is equipped with a table-top delegate unit which allows them to speak, register a request-to-speak, listen to the speaker and vote.

The LBB 3544/00 is the standard delegate conference 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.

Two microphones are available, with standard and extended stem lengths respectively.
