The built-in DSP digital audio processing module can effectively guarantee the internal information of the system, and minimize interference, distortion and crosstalk.
Built-in adaptive feedback suppression (AFC) function, which can effectively prevent acoustic feedback from causing the roar, ensuring that the sound quality is not damaged when adjusting the gain.
Built-in ambient noise elimination (AEC) function, which effectively eliminates local noise, and enables high-quality audio to be delivered in real time.
The built-in digital equalizing circuit (EQ) function can greatly enhance the sound pressure level of the venue, ensuring the sound is plump, soft and flexible.
Built-in automatic gain control (AGC) function, which USES intelligent level control technology to control the remote acoustic quality of the unit.
The system is equipped with a 2.8-inch LCD display and a control key, with the Chinese and English menu showing that you can order any language on demand.
The built-in camera tracks the main board card, and the following software and control keyboard can be used to set up, save and automatically call.
Systems support VISCA, PELCO - D, PELCO - P, and HUAIN's regular control protocols, with RS485 / RS232 control;
Built-in 3 x 5 roadmap clear video matrix switching, with 3-way video ring out function, easy to manage multi-channel video signal;
When the single microphone is turned off, automatically tracks to the previous unit, which automatically returns to the preset panorama when the microphone is turned off.
The system has a first-in-first-out work mode, the number of speeches can be customized and the number of speakers can be set to 1 to 6.
The system can be set to free discussion mode, and all conference units are free to open their speeches without limitation of quantity.
The system supports application speech mode, queuing mode, computer allowed mode, and speech limit mode through PC conference management software.

System support button check-in and IC card check-in, check-in, check-in time Settings, check-ins for real-time dynamic display.
The ability to sign in, vote, vote, respond, and score on the conference host will be displayed on all device screens.
To support the way of the name and bearer of the ballot, all voting can be exported and archived and supported in the printed form;
It has the ability to extend the simultaneous interpretation of the simultaneous interpretation of the eight channels, 16 channels, 32 channels and 64 channels.
The system has the function of "hot plug" and "hot plug" to ensure the safety and stability of system operation.
The system can detect the number of the system and the status of the system, and the operating status of the system is clear.
Have the alarm signal input interface, when the public broadcasting alarm system start-up moment automatically pauses the meeting, and sends the alarm information to the participating unit.
With the professional recording output interface, it is convenient to record the audio of the meeting.
Access to other capacitor microphones or moving coil microphones to provide more options for users;
The input output volume isostatic adjustment can be used to adjust the input and output signal of the system to prevent the adjustment of the audio.
The system can also access 8 President units at the same time, the President unit has the priority function, also can close the other representative units that are speaking.
Three representative units can be set up as VIP units, the VIP units can be opened freely without restriction, and they will not be affected by other units.
Strong anti-mobile jamming ability, no noise at the time of the call, even in the room where there is a cellular signal shield.
Multi-function meeting host and PC computer, programmable central control system adopt rs-232 connection mode, control mode security and stability;
