Zero distortion: the voice recognition method has the least damage to the voice, and theoretically it can achieve zero damage.

Zero feedback: as long as the recognition rate of voice recognition is high enough, zero feedback can be achieved.

Feedback suppression AFC: built-in 5-level sound screen to accurately screen the sound signal of the speaker and filter it out.

Noise suppression ANR: built-in 15 level noise suppression to make the system more pure;

Automatic equalizing AEQ: built-in 5-level automatic equalizing, which can automatically adjust the equalizing in real time according to the environment.

The speaker energy suppression ratio, MIC pickup speaker energy, and speaker energy suppression amount can be displayed in real time;

The original voice recognition level is used to judge whether the equipment works in the best voice recognition state;

The combination of "Line/Microphone" mode switch,"High/Medium/Low" level selection switch and “MlC" gain knob can adapt to multiple groups of different input level settings, so that the input level signals within the range of +6 dBu to -80 dBu can work in the best sound recognition state;

The three input connections are female XLR, of which two are input signals with+48V phantom power supply, and the other is line reference signal input to enhance the voice recognition feedback suppression function;

Two output interfaces are male XLR, and two output signals are processed independently;

24 mm x 179 mm large LCD screen, all specifications are displayed on one screen, without page turning operation;

Connecting PC software can not only realize all parameter control, but also realize automatic equalization AEQ verification, so that automatic equalization can adapt to different working occasions.

PC software provides USB, RS485, TCP/IP and WiFi connection modes;

A single machine provides 30 groups of programmable user programs, 10 of them can be stored and called on the panel:

The traditional central control and network central control can be realized through RS485 and TCP/IP. The network central control is two-way transmission, which can control and obtain various parameters of the equipment in real time;

The equipment can accept a wide range of AC voltage input, with the input range of AC 90~240V 50/60Hz;
