F-300 Feedback Suppressor

Features:

1. The feedback suppressor equipped with AI intelligent algorithms enables precise identification and dynamic suppression of啸叫 points, with 4 selectable AI suppression levels. It achieves fully automated AI processing, delivering far superior啸叫 prevention performance compared to traditional devices. This ensures stable and pure audio transmission while significantly extending the microphone's pickup range;

2. Equipped with AI-powered noise cancellation algorithms, it accurately captures ambient noise and human voices, eliminating environmental disturbances (such as applause, rustling paper, or clapping on tables) while amplifying human voice signals;

3. Equipped with a 2-inch color LCD display, supporting bilingual display switching between Chinese and English for clear operation status, making it easy for beginners to quickly get started;

4. Input channel with 2-channel combo interface, compatible with various audio devices, paired with a 2-position sensitivity switch for precise matching of input signals of different intensities;

5. The output channel provides dual specifications with 2 XLR male jacks and 2 6.35mm jack ports, meeting the connection needs of various scenarios such as stages and meeting rooms, and is compatible with all types of audio systems;

6. All phantom power input channels support 48V phantom power, compatible with professional equipment such as condenser microphones, eliminating the need for additional power adapters;

7. Balanced adjustment: Each channel is equipped with 16-band PEQ for precise optimization of audio frequency bands, enhancing sound quality performance;  

8. Gain control with per-channel gain levels from 0 to 18, allowing volume adjustment based on on-site requirements;  

9. The anti-misoperation design supports a 2-level panel lock function, which prevents accidental parameter touches from causing equipment malfunctions, ensuring stable operation in scenarios such as performances and meetings;  

10. Data Storage and Backup  

The system features automatic data saving functionality and supports manual backup of critical parameters. It can store up to 20 user programs, allowing one-click access to preset configurations for different scenarios, significantly enhancing work efficiency;
