3.★The conference control host can connect up to 128 conference units. Through the conference expansion host, a conference system can connect up to 1,000 conference units;

4. USB/SD card MP3 recording and playback function and graphic display, Bluetooth playback, high-fidelity WAV and MP3 output. It can be used as MP3 background music input when not recording

5. It adopts 8-core and standard, with extended host interface and conference unit interface; "hand in hand" or "T-type" connection mode;

6. It provides 1 RCA audio input interface, supports external fire alarm audio and background music input, and 1 unbalanced input;

7. It provides 2 RCA audio output interfaces, 1 balanced output, and 1 unbalanced output;

8.★Supports five-level gain manual adjustment function for bass, treble, and total volume;

9. Speaker number limit function: the number of speaking units is 1/2/4/6, and the chairman unit is not limited;

10. Support FIFO-first-in-first-out speaking mode, NORMAL-take-turn speaking mode, FREE-free speaking mode, APPLY-apply for speaking mode;

11. The audio processing uses a digital equalization module and a noise reduction processing module to make the sound clear and thorough;

12. It has a video switching RS-232 communication interface, which is combined with the central control system to manage the conference system in a unified manner, replacing the management software;

13.★The system supports three voting methods:

A) Voting method: Agree/Abstain/Oppose;

B) Election method/Survey method: 1/2/3/4/5;

C) Response method/Evaluation method: --/-/0/+/++.

14.★PC independent control interface, supports PC-side control of conference mode, speaker number limit, conference volume gain adjustment, management of sign-in, voting score and voting process data;

15. Independent ID code of conference unit can be set, and automatic camera tracking function can be realized with central control system or camera tracking host;

16. Remote telephone conference can be carried out with telephone coupler;

17.★Noise elimination, howling suppression, automatic gain function (optional);

18. Metal shell, the connection between the line and the shell is strengthened with the ground wire to ensure the ability to resist static electricity of 8500V;

19. The host can be installed on a 19-inch standard cabinet.
