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-WDD-D Wireless Dual Discussion Unit enables
participants to speak, register a request-to-speak, and listen
to the speaker.
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 also accommodates two separate headphone
connections with individual volume control on either side of
the unit, allowing one unit to serve two delegates. It can be
converted to a full dual-use unit by replacing the
microphone button with two separate buttons for individual
microphone control and individual delegate identification
(DCN-DISBDD dual-use buttons, to be ordered separately).
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.
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).
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.
