FBX-210 automatic acoustic feedback suppressor with 2-channel input, 24V phantom power, and digital frequency shift technology for anti-howling.

FBX-210 Automatic Acoustic Feedback Suppressor (2-Channel with Phantom Power)

The FBX-210 is a professional 2-channel automatic acoustic feedback suppressor designed for zero-maintenance operation. By utilizing advanced echo cancellation and digital frequency-shift technology, it eliminates room reverberation and howling before it occurs. Featuring independent 24V phantom power and a selectable auto-adaptive filter (Fast/Precise modes), it dynamically adapts to moving microphones or complex fixed acoustic environments, delivering up to 12dB of system gain without distortion.

Smart Anti-Howling Technology for Dynamic Conferences

The FBX-210 leverages cutting-edge digital frequency shift technology and masking noise algorithms to detect and eliminate reverberation components before acoustic feedback occurs[cite: 151, 152]. Enjoy a smooth, stable sound with no floating or metallic tail noises[cite: 170, 171].

Engineered for versatility, the auto-adaptive filter features two operation modes. The “Fast” mode is perfect for discussion systems where microphone positions frequently change, while the “Precise” mode is optimized for complex, fixed acoustic environments like lecture halls[cite: 162, 163, 164, 165, 166].

Core Advantages

  • Zero-Maintenance Operation
    Fully automatic environment adaptation requiring no manual debugging[cite: 155, 158].
  • Dual Input with Phantom Power
    2-channel balanced/unbalanced inputs with a selectable 24V phantom power module[cite: 153].
  • Massive Gain Boost
    Safely increases system gain by up to 6dB (max 12dB) under any usage condition[cite: 156].
