Wired discussion conference control system host (10 meters from host to chairman)

Jt-500 series is a new intelligent, fully functional digital conferencing system, which perfectly integrates digital technology and integrated network technology into the conference system, and fully combines advanced digital technology, network technology and audio technology.

It can be combined with intelligent central control system to provide more complete solutions for efficient modern conference system engineering.

Technical Features:

1. Adopt digital technology as the core, built-in high-performance CPU, and support discussion.

2. The audio signal is processed with 32BIT high-speed floating point DSP, with a bandwidth of 20Hz~20KHz and perfect sound quality

3. High performance switching power supply, long distance transmission will not have any impact on the sound quality

4. Anti-interference circuit design to eliminate all interference of mobile phone signals

5. Equipped with a 2.8-inch LCD screen for independent button operation

6. Two-channel microphone connection, each support 40 units, can be connected to 80 units, support 10 chairman units, plus extender can be extended to 512 meeting units, the main machine outlet has the traditional 8-cell hand-holding interface and 4-channel RJ45 network cable interface.

7. With rS-232 interface of central control code, it can be connected to the central control system

8. Multi-channel audio input/output interface, which can be connected to sound reinforcement or recording equipment

9. Host computer and computer can be connected and communicated by USB local mode, and the SYSTEM can be set up by PC software.

Can also do not need the computer directly on the host system to set up, support online update code

10. There are multiple meeting modes: FIFO (first-in, first-out), FREE (all-open), C-only (Chairman first), LIMIT (restricted speech)

11. The number of speeches and the functions of voice control can be set

12. With time-limited speech function, the time countdown can be set. After the countdown, the unit that is speaking will be automatically closed

13. It can be installed on the 19-inch standard cabinet for easy storage and storage
