The digital feedback suppressor is a function specially designed for conference systems, not only suitable for conference rooms, churches, star rated hotels, auditoriums, conference centers, multifunctional halls, and digital court applications. The intuitive graphical PC control interface in both Chinese and English, with clear signal flow, not only brings high-quality audio, but also has the characteristics of strong compatibility, flexible control, and simple operation, improving environmental sound pressure/preventing system howling
1. Each channel can be equipped with up to 12 dynamic notch filters, 12 PEQs, with a resolution accuracy of 1HZ and a working frequency of 20HZ-20KHZ 2. 24BIT high-performance A/D and D/A conversion 3. The response time can be set to fast, medium, or slow at 3 speeds, and the notch filter Q value is automatically selected in two levels. 4. Automatically scan and suppress whistling points. 5. The noise gate function can suppress weak noise interference in the system. 6. Input compression function to eliminate feedback and expand vocal dynamics. 7. Each channel. Gain -80DB to 0DB 8. Each channel is equipped with four frequency shift options, which are used in conjunction with notch filters to achieve outstanding anti whistling effects
