1. Unique DCP/MOVE digital processing and transmission technology, no matter how many devices are undisturbed, all digital transmission overcomes the attenuation problem of long-distance transmission. The transmission distance of six core wire can reach 250 meters, and the transmission distance of network cable can reach 150 meters;
2. Long distance transmission has no impact on sound quality and can achieve CD level sound quality;
3. Built in environmental noise canceller (AEC), which can effectively eliminate local noise;
4. Built in digital equalization circuit, which can significantly improve the sound pressure level of the venue;
5. Built in adaptive feedback suppressor (AFC), which can effectively prevent whistling;
6. The wireless conference host interacts with voice and data through wireless transceivers, using 2.4G all digital frequency hopping (DSSS) modulation communication technology and ISM frequency band to ensure that the audio delay is less than 5.5ms;
7. The connection method adopts a 6-core DIN shielded cable or a 2-meter Category 6 Ethernet cable, which can effectively prevent electromagnetic interference to the line;
8. Optional functions (the system host supports dual machine hot backup, with strong system stability, suitable for large conference center applications);
9. Adopting ID addressing, customizable numbering, automatically detecting the online list of hosts and units upon startup, and real-time monitoring of system operation;
10. Pioneering a 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; (At the request of the bidder, samples can be provided for on-site demonstration during bidding)
11. Built in voting motherboard with data management functions for check-in, voting, election, scoring, and response;
