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.

To prevent acoustic feedback, a feedback suppressor is built‑in.
