To the participant the most important part of a
conference system is the discussion unit. Bosch has
built on the elegant design of the
DCN Next Generation discussion units to create a new
series of wireless discussion units with unrivalled
looks and features.
The DCN‑WDV‑D Wireless Discussion Unit with Voting
enables participants to speak, register a request-to-
speak, listen to the speaker, and vote.
Functions
Speech intelligibility
Maximum speech intelligibility is guaranteed at all
times. Operating in the 2.4 GHz (license free) band,
the wireless discussion units produce crystal-clear
sound due to a very high signal-to-noise ratio and
antenna diversity. This means the signal is transmitted
along different propagation paths, ensuring optimal
receipt. The system is also protected against
interference from mobile phones and other equipment
that makes use of Bluetooth or microwave signals.
Security
Wireless communication means extra security
considerations. The DCN Wireless system and
discussion units therefore feature 128‑bits AES
encryption to prevent eavesdropping and unauthorized
access. Encryption ensures the information within the
system remains confidential.
Microphones
A socket is provided to connect the pluggable
microphones which are available in short and long
stem versions (DCN‑MICS and DCN‑MICL, to be
ordered separately).
Voting
The unit has five voting buttons. The yellow indicator
rings around the voting buttons confirm vote
selections.
Headphones and loudspeakers
The unit also accommodates two headphone
connections, so the speaker can be heard clearly even
in situations with excessive background noise.

To prevent acoustic feedback the built-in loudspeaker
is muted when the microphone is on. If enabled, the
headphones volume is also automatically reduced to
prevent acoustic feedback when the microphone is on.
Rims and buttons
Different rims are available to allow matching with the
interior (DCN‑DISR, to be ordered separately).
The unit can be used as:
• a single delegate unit
• a dual delegate unit
• a chairman unit (DCN‑DISBCM chairman buttons, to
be ordered separately)
• a single delegate unit with auxiliary button (to be
used as an usher call, for example).
The unit has five voting buttons. The yellow indicator
rings around the voting buttons confirm vote
selections.
Battery maintenance
Simple battery maintenance is essential in a wireless
system. A unique feature of Bosch's wireless
discussion units are the separate rechargeable battery
packs (DCN‑WLIION, to be ordered separately). These
Lithium-ion battery packs can be removed and
replaced in a matter of seconds, providing maximum
flexibility in recharge scheduling.
