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‑WDCS‑D Wireless Discussion Unit with Channel
selector enables participants to speak, register a request-
to-speak, listen to the speaker or to an interpreter of their
choice.
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.
Channel selector
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. This enables rapid
selection of the required language channel.
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).
Headphones and loudspeakers
The unit also accommodates two headphone connections,
so the speaker can be heard clearly even with excessive
background noise. To prevent acoustic feedback the built-
in loudspeaker is muted when the microphone is on. If
enabled, the headphone 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).
Battery maintenance
Simple battery maintenance is essential in a wireless
system. A unique feature of Bosch's wireless discussion
units is 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.
Controls and Indicators

Alphanumeric display for language channel selection
with number and abbreviated channel name
Channel up and down selection buttons

ring:
