"Wireless 5G digital conference chairman unit, 3-inch LCD screen display equipment status, easy to operate, with permission buttons and speak button, participants only need to press the speak but
1. the chairman of the unit using the latest six-core ARM Cortex-A53 chip, also configured with multi-core neural distributed GPU accelerated processor, to ensure that the distributed transmission signal acquisition and sending the stability and reliability;
2. ★ support HD-Sound digital audio and video transmission technology, through an ordinary network cable to send and receive 1024 audio channels at the same time;
3. the use of 24bti/192KHz top ADC chip AK5392, dynamic range and signal-to-noise ratio to reach the CD sound quality
4. the use of multi-channel digital filter transmission technology, to solve the mutual interference between the units resulting in crosstalk, murmurs, broken sound, noise;
5. ★ 3-inch colour LCD screen, you can display the speech status, voting status, clock, unit IP address,
6. ★ POE switch direct power supply, using a standard network cable 586A way to connect to the switch, the system is simple and flexible to build.
7. ★Support clock display, with a positive time to limit the speech, countdown to limit the speech function, to improve the efficiency of conference management;
9. ★Support speech and discussion, check-in, voting, camera positioning tracking, tea service function
10. up to 40-80CM pickup distance, complete to meet the vast majority of high-demand conference room use
11. the chairman of the unit has priority control, you can pause on behalf of the unit to speak, you can also close the representative of the speech
12. ★ support microphone volume sensitivity adjustment
13. ★ support microphone pole red, green LED lights alternately flashing status shows the need for tea services
14. the use of intelligent neural distributed algorithm technology, completely eliminating the phenomenon of multiple units at the same time to boot leading to the host dead;
15. using IEEE1588 precision clock protocol for clock synchronisation, zero delay transmission of audio and video signals.
16. using uncompressed audio transmission, 48K sampling rate, to provide clear and perfect voice
17. ★ waterproof touch keys, effectively avoid the mechanical key sound impact;
