DCS-8920 Series Intelligent Conference Terminals

Functions and Features

• Adopt all-digital conference technology, conform to IEC60914 international standard;

• Simple and steady mesa type strong antistatic function design, accord with ergonomics, have modern science and technology feeling extremely;

• It is made of toughened glass with high strength, and its appearance is very textural.

• Adopting aluminum alloy integrative forming gun microphone pole and adopting the principle of sound interference, it has excellent over-directivity.

• A multi-functional conference terminal with speech discussion, video tracking, voting and conference services;

• Has the short message function, may carry on the internal communication with other units or the host;

• Using DSP/DDOV digital processing and transmission technology to overcome the attenuation problem of long-distance transmission, the distance of six-core wire can reach 250 meters, and the distance of network wire can reach 150 meters.

• Equipped with anti-vibration pick-up head, can minimize the noise caused by the vibration of the desktop;

• Optional 3.5-inch TFT color touch screen (optional display of speaking time, speaking time, calendar, etc.);

• The use of professional silent mechanical keys, so that the meeting is quiet, calm and focused;

• Full-metal square-column microphone rod with double vibration mode pick-up head;

• The connection mode adopts 6-core DIN shielded cable or 2-meter over 6-type network cable (6-core cable can be used for high-power unit), which effectively avoids and prevents electromagnetic interference of the line, simultaneously transmits 64 languages, and ensures that the data will never be lost;

• The connecting cable can lead out from the bottom and the back, which can guarantee the moving position of the speaker and the neatness of the desktop.

• The system supports many kinds of connection modes, such as linear, T-shaped head and ring hand.

• The unit is passive equipment, the conference host provides 24V power, low power consumption design, a single can connect 25 conference units;

• Adopt digital strong anti-jamming technology to ensure that the equipment in the venue is not disturbed by mobile phone, Bluetooth, radio, WiFi and other signals;

• Cooperating with the camera, the camera can be tracked automatically through the conference host, control keyboard or PC software preset;

• The system has FIFO, FIFO, (optional) Chairman computer allowed, free discussion, limited mode, the number of speakers can be set up 1 to 6;

• (optional) use PC conference management software to support that mode of apply for speaking, compute permission, speaking time limit and queuing;

• Designed with advanced electrostatic isolation technology, static electricity can be avoided even in dry environments and regions.

• Between the units with the line live “hot swap” function, so that the security of the system get greater protection;

• The system adopts digital audio processing technology, and the frequency response can reach 40Hz-20KHz, which is close to the sound quality of CD.

• The microphone pole is provided with an indicator light ring, which can display the status information such as speaking, setting video, unnumbered ID, etc.

• The system adopts ID addressing mode, conference management software or conference host to customize the ID number of the unit to avoid duplicate ID number.
