Functional characteristics
1. Equipped with 1.8"LCD full color screen, CAP sensing touch button, precise positioning, fast control, no mechanical button, no wear, unlimited life;
2. Made of aero-grade aluminum magnesium alloy material, polished by 20 processes; The bar joint and all studs are made of pure copper material to restore the sound quality and ensure the quality stability;
3. DSP/DDOV digital processing and transmission technology is adopted to overcome the problem of long-distance transmission attenuation, and the line distance can reach 150 meters;
4. The unit is a passive device with 24V power supply provided by the conference host and low power consumption design. The six-core unit can connect 25 conference units in a single channel and the network cable unit can connect 15 conference units in a single channel.
5. Digital strong anti-interference technology is adopted to ensure that the equipment in the venue is not interfered by mobile phones, Bluetooth, radio, WiFi and other signals;
6. The system has a first-in, first-out working mode, the number of speakers can be set up 1 to 6, the chairman is not restricted;
7. Advanced ESD isolation technology design, even in dry environments and areas can avoid static electricity;
8. There is a "hot swap" function between the units, so that the security of the system is more guaranteed;
9. Electret super heart-shaped directional microphone to ensure the pickup distance and sound quality, the pickup distance can reach 50cm;
10. The system adopts digital audio processing technology, the frequency response can reach 40Hz-20KHz close to CD sound quality effect;
11. The system adopts ID addressing mode, and the conference management software or the conference host defines the ID number of the unit to avoid ID number duplication;
12. The cable can be drawn from the back to ensure that the speaker can move and the desktop can be clean;
13. Built-in high-pass filter function, convenient to cut the low-frequency components of the sound when needed;
14. The six-core system can access 100 chairman units, and the network system can access 120 Chairman units, which have priority function and can also close other representative units that are speaking;
15. Built-in 2W high-fidelity speaker, automatically mute after opening the microphone, not easy to produce screaming, clear sound quality, volume can be freely adjusted;
