For the participants, the most important part of the

 conference system is the conference discussion device. Based on the elegant design of the new generation of DCN conference devices, Bosch has launched a new series of wireless conference and discussion devices, which not only have a dazzling beautiful shape, but also provide unparalleled excellent performance. DCN ￣ WDD ￣ D wireless dual representative conference discussion device can enable participants to speak, register their requests and listen to others. Basic function speech intelligibility ensures the highest speech intelligibility at any time. The wireless conference device uses 2.4 GHz operating frequency band (no license required), with ultra-high signal-to-noise ratio and excellent antenna diversity, which can produce excellent sound effect. This means that the signal can be transmitted along a variety of propagation paths to ensure optimal signal reception. In addition, the system also has perfect protection function, which is not interfered by mobile phones and other devices using Bluetooth or microwave signals. Secure wireless communication means more security considerations need to be considered. Therefore, the DCN wireless system and conference devices adopt 128 bit AES encryption technology to prevent eavesdropping and unauthorized access. The encryption function can ensure the confidentiality of information in the system. Microphone with a socket for short / long handle pluggable microphones (DCN ￣ MICs and DCN ￣ micl, to be ordered separately). In addition, two separate earphones with separate volume controls can be connected on both sides of the device, so that one device can be used by two representatives. By replacing the microphone button with two separate microphone buttons (for separate microphone control and separate representative identification), it can be converted into a fully functional dual representative device (DCN ￣ disbdd double representative button needs to be ordered separately). To prevent acoustic feedback, the built-in speaker is muted when the microphone is turned on. If the headset is enabled, the headset volume will also automatically decrease when the microphone is turned on to prevent acoustic feedback.
