Functional characteristics
1. Automatic detection of on-site whistling point function, through the DSP system to filter the sound, bass compensation automatic mixing, intelligent high-speed feedback processing, full digital to minimize the feedback.
2. Full-color Chinese display, 2-inch OLED display content is more comprehensive and intuitive.
3. Automatically adapt to the acoustic environment, no need to debug, fast correction function, ensure sound quality, reduce delay.
4. One-click setting, and engineering debugging more convenient and rapid.
5. When using more than ten microphones at the same time, it will effectively increase the microphone pickup distance of 30 ~ 150cm.
6. Under normal use, the machine automatically ADAPTS to the acoustic environment without debugging (the automatic adaptation process takes about 10 seconds), and the whole system will gain an additional 6 ~ 15dB.
7. If the sound quality is abnormal in the harsh environment (after multiple whistling in the system debugging process), please reduce the volume appropriately, and then press the quick correction button of the machine, at this time, a pink noise signal of -6dB will be randomly generated for 1 second, which helps to improve the sound field correction to improve the anti-whistling.
8. Applicable places: large, small and medium-sized conference rooms, lecture halls, multi-function halls, courts, banquet halls, education systems, etc.
