For participants, the most important component of the conference system is the conference discussion device. In adhering to a new generation of DCN meeting elegant design, on the basis of Bosch launched a new series of meetings to discuss wireless devices, they not only have to make people dazzling beautiful modelling, also provides incomparable excellent performance. The DCN WDV‑D wireless conference device with voting function enables participants to speak, register requests for statements, listen to others and vote. Basic functional speech intelligibility ensures maximum speech intelligibility at all times. The wireless conference device USES a 2.4ghz operating frequency band (without a license), has high signal-to-noise ratio and excellent antenna difference, and can produce excellent sound effect. This means that the signal can be transmitted along multiple propagation paths to ensure the best signal reception. In addition, the system is fully protected from mobile phones and other devices that use bluetooth or microwave signals. Secure wireless communications means more security considerations need to be considered. Therefore, the 128-bit AES encryption technology is adopted in the DCN cable-free system and conference device to prevent eavesdropping and unauthorized access. Encryption function can ensure the confidentiality of information in the system. Microphone it has a socket for connecting short/long handle pluggable microphones (DCN‑MICS and DCN‑MICL, which need to be ordered separately). Voting the device has five voting buttons. The yellow indicator ring around the voting button is used to confirm the voting selection. Earphones and speakers are also provided with a two-way earphone connection that allows you to hear people even when the background sounds are very noisy. To prevent acoustic feedback, the built-in speakers turn silent when the microphone is turned on. If the headset is enabled, the volume of the headset will also automatically drop when the microphone is turned on to prevent acoustic feedback.
