3 Introduction and overview
The delegate units are part of the Bosch Digital Congress Network (DCN) system.
The delegate unit with fixed short or long microphone (DCN-DS/L) enables participants to
speak, register a request-to-speak and listen to the speaker. The microphone stem is flexible.
The delegate units accommodate two headphone connections. The built-in loudspeaker is
muted when the microphone is on to prevent acoustic feedback.
The delegate unit with channel selector (DCN-DCS) enables participants to speak, register a
request-to-speak and listen to the speaker. A socket is provided to connect the pluggable
microphones (DCN-MICS and DCN-MICL, to be ordered separately). The unit has a built-in
channel selector that makes it suitable for discussions in which more than one language is
used and simultaneous interpretations are available. The channel selector includes two up
and down channel select keys and a display showing the number and the abbreviation of the
languages, enabling rapid selection of the required language channel.

The delegate unit with voting (DCN-DV) and channel selector (DCN-DVCS) enables
participants to speak, register a request-to-speak, listen to the speaker and vote. A socket is
provided to connect the pluggable microphones (DCN-MICS and DCN-MICL, to be ordered
separately). The unit has five voting buttons for all types of voting. The yellow indicators
above the voting buttons are used to prompt users to register their presence, to start voting
and to confirm their vote. When the unit’s attendance LED is yellow, it indicates the delegate
is present.
Besides the voting function, the unit (DCN-DVCS) has a built-in channel selector, which makes
it suitable for discussions in which more than one language is used and simultaneous
interpretations are available. The channel selector includes up and down channel select keys
and a display showing the number and the abbreviation of the languages, enabling rapid
selection of the required language channel.
