For participants, the most important component of the conference system is the conference installation. In adhering to a new generation of DCN meeting elegant design, on the basis of Bosch launched a new series of wireless device meeting, they not only have dazzling modelling, also provides unparalleled performance excellence. The DCN WD‑D wireless conference device enables participants to speak, register requests for statements and listen to others. Basic functional speech intelligibility ensures maximum speech intelligibility at all times. This wireless conference device USES a 2.4ghz operating frequency band (without a license), has a 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. The system is also 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). Earphones and speakers in addition, the device also provides a two-way earphone connection that allows you to listen to others even if the background sounds are very noisy.
