F-2000 Intelligent High-Speed Feedback Suppressor

  • Rack-Mountable Design & Intuitive Operation

    1U aluminum alloy standard chassis for rack mounting; 2-inch TFT color LCD screen for status display, 2-channel independent one-key control, and keyboard lock to avoid misoperation.

  • Powerful AI-DSP Audio Processing

    Equipped with high-performance DSP chip and self-adaptive algorithms; realizes automatic howling suppression, spatial dereverberation, and intelligent noise reduction without debugging, and AI voice processing enhances speech clarity while increasing gain by 6–15 dB.

  • Professional Technical Parameters & Stable Performance

    Supports XLR and 6.35 mm balanced/unbalanced input/output; covers 40 Hz–20 kHz frequency response, < 0.05% distortion, > 100 dB SNR, and works with AC 110 V/220 V power supply for reliable audio performance.

Functional Features

1.  Standard chassis design with a 1U aluminum alloy panel, suitable for rack mounting.

2.  High-performance DSP digital signal processor, equipped with a 2-inch TFT color LCD screen for displaying status and operation functions.

3.  Brand-new algorithm requiring no debugging; the system automatically suppresses howling points upon connection, featuring high precision, reliability and ease of use.

4.  Adaptive environmental howling suppression algorithm with spatial dereverberation function. It prevents reverberation amplification during sound reinforcement in reverberant environments, and also has the function of suppressing and eliminating reverberation.

5.  Environmental noise reduction algorithm with intelligent voice processing. It reduces non-human noise during voice amplification, improves speech clarity, and realizes intelligent removal of non-human voice signals.

6.  AI intelligent voice processing with the ability to distinguish and enhance loud signals while preserving soft signals. It maintains the coherence of speech intonation and speech intelligibility, ensures listening comfort, and increases the gain by 6–15 dB.

7.  2-channel independent processing with one-key control for simple operation; the keyboard lock function prevents misoperation.
