Touch Digital Conference Delegate unit- with electronic table card
JM-720D
  • The representative unit adopts the latest six-core chip to ensure stable and reliable collection and transmission of network transmission signals

DESCRIPTION

1. The representative unit adopts the latest six-core chip to ensure stable and reliable collection and transmission of network transmission signals;

2. Digital audio and video transmission technology, simultaneously transmitting and receiving multi-channel audio signals through an ordinary network cable;

3. Adopting time-division transmission technology to solve the crosstalk between the units, causing crosstalk, noise, frequency loss, and crash;

4, using a color LCD screen, you can display the speech status, voting status, clock, unit IP address;

5. Support POE switch to directly supply power, and the conference unit is connected to the switch by standard network cable. The system is simple and flexible.

6, all conference units use a star structure, any unit failure will not affect the use of other units

7, using partition sharing technology, a conference host supports 3-4 conference rooms, independent sound output, do not interfere with each other;

8. Support speech discussion, sign-in, voting, camera positioning tracking function;

9, full touch operation, support electronic table card function, display the name of the participants;

10, built-in microphone volume adjustment, easy to grasp the voice of the speech;

11. Adopt two-way feedback technology to improve system security and stability;

12, using intelligent neural network algorithm technology, to prevent multiple units from booting at the same time causing the host to crash;

13. Adopt clock protocol for clock synchronization, improve timing synchronization capability, and provide low-latency transmission of audio and video signals;

14, using uncompressed audio transmission, 48K sampling rate, providing clear and perfect CD-quality sound quality.

15. With anti-cell phone interference function, the microphone has automatic gain, and the sensitivity is automatically adjusted to prevent howling.
