High-end All-Digital Network Conference Host

Functions and characteristics

• According to IEC60914 international standard, 32-bit industrial embedded processor with high performance ARM Cortex A8 is adopted. The main frequency is 800MHz, 256M memory, and the system is stable and fast.

• The original digital processing and transmission technology of DCP/MOVE, no matter how many devices are not disturbed, can overcome the attenuation problem of long-distance transmission, the transmission distance of six-core wire can reach 250 meters, and the transmission distance of network wire can reach 150 meters.

• Long-distance transmission has no effect on the sound quality, which can reach CD grade.

• Built-in Ambient Noise Canceller (AEC) to effectively eliminate local noise;

• Built-in digital equalization circuit, can greatly improve the sound pressure level of the conference site;

• Built-in adaptive feedback suppressor (AFC) can effectively prevent whistling;

• The wireless conference host carries on the voice data exchange through the wireless transceiver, adopts the 2.4 G all-digital frequency hopping (DSSS) modulation communication technology, the ISM frequency band, guarantees the audio frequency delay to be less than 5.5 mS;

• The connection mode adopts 6-core DIN shielded cable or 2-meter over 6-type network cable, which can effectively prevent electromagnetic interference to the line.

• Optional features (system host supports dual-machine hot backup, system stability, suitable for large conference center applications);

• Adopting ID addressing, the system can be self-defined, and the on-line list of hosts and units can be automatically detected on the startup, and the system operation can be monitored in real time.

• First 4.3-inch full-color touch screen, with bilingual information display in Chinese and English, with dual functions of system navigation display and centralized control;

• Built-in voting motherboard card, with check-in, voting, election, scoring, response data management functions;

• Built-in SD camera tracking motherboard card (configurable high-definition video tracking), no need to configure the computer, offline video tracking, built-in 8-in-6 out/8-in-4 out/8-in-4 video matrix;

• A single camera can be connected to 8 cameras at the same time to achieve automatic camera tracking function. (Holds the Sony VISICA, PELCO-D/P, BO1 protocols and RS-485/RS-232 control);

• 2 RS-232 interfaces, programmable central control system for control;

• The wired microphone and the wireless microphone can be compatible with one host computer at the same time;

• Built-in video tracking processor to support the expansion of the video matrix, unlimited expansion of the camera camera camera linkage, with camera linkage screen freeze function;

• The 4.3-inch touch screen of the machine can be detached from the computer to complete the setting of the camera tracking and reduce the cost input.

• A 6-core cable can transmit up to 64 languages and various signals;

• Supports 48 kHz audio sampling frequency with channel frequency response of 20 Hz to 20 kHz;

• The output gain of the conference unit can be adjusted centrally by the host computer, and the audio frequency adjustment lock can be set.
