Dual channel stereo feedback suppressor

Functional Features

1. Fully automatic detection of on-site howling points function, filtering sound through DSP system, automatic mixing with bass compensation, intelligent high-speed feedback processing, and maximizing digital elimination of feedback.

2. Full color Chinese display, 2-inch OLED screen displays more comprehensive and intuitive content.

3. Automatic adaptation to acoustic environment, no need for debugging, fast correction function, ensuring sound quality and reducing latency.

4. One click setting makes project debugging more convenient and fast.

5. When using more than ten microphones simultaneously, it will effectively increase the microphone pickup distance by 30-150cm.

6. Stereo channel input and output, more compatible with other engineering equipment.

7. Under normal use, this device does not require debugging and automatically adapts to the acoustic environment (the automatic adaptation process takes about 10 seconds). The entire system will gain an additional 6-15dB of gain.

7. If the sound quality is abnormal in harsh environments (after multiple howls during system debugging), please reduce the volume appropriately and then press the local quick calibration button. At this time, a random signal sound of 1-6dB will be generated, and the sound quality will return to normal.

Applicable locations:

Large, medium and small conference rooms, lecture halls, multifunctional halls, courts, banquet halls, educational systems, etc.
