Bosch DCN‑WDV‑D Wireless Discussion Unit with Voting



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.

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-tospeak, listen to the speaker, and vote.

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.
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 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.

  • Five voting buttons
  • Usable as delegate or chairman unit
  • Separate battery pack, easy to change and charge
  • Advanced power saving techniques

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.
