The Bosch DCNM-WD is a wireless device for use with the DICENTIS Wireless Conference System. The DCNMWD enables participants to speak, register a request-to-speak, and listen to the speaker during a meeting via the built in loudspeaker or headphones.

The loudspeaker and microphone can be active at the same time for a face‑to‑face meeting experience. The sound is crystal‑clear due to a very high signal‑to‑noise ratio and smart frequency selection. To prevent acoustic feedback, a feedback suppressor is built‑in.

The device can be easily configured as a single-use, dual-use or chairperson Wireless Device via the web interface of the Wireless Access Point (DCNM-WAP).
