Introduction
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.
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. The system is also protected
against interference from other wireless equipment such as
mobile phones, Bluetooth devices and WiFi networks.
Wireless communication means extra security
considerations. The DCN Wireless system and discussion
units therefore feature multiple-layer protection to prevent
eavesdropping and unauthorized access. Digital protection
ensures the information within the system remains
confidential.
The DCN-WDV-D Wireless Discussion Unit with Voting
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. The yellow indicator rings
around the voting buttons confirm vote selections.
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.
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).
The unit can be used as:
• a delegate unit
• a chairman unit (DCN-DISBCM chairman buttons to be
ordered separately)
• a delegate unit with auxiliary button (can be used as an
usher call for example)
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.
