FE-228 AI Feedback Suppressor

Peripheral Equipment

• AI predictive anti-feedback with 4-level feedback depth, offering 8-18dB acoustic gain, high-fidelity sound and minimal audio distortion.

• AI noise reduction with 5-level noise depth. It intelligently distinguishes human voice from ambient noise, suppresses wind noise, bump sounds and echo for improved speech clarity.

• Adopts domestically-developed AI chip, ideal for bidding projects in military, government, enterprise and education sectors.

• 2-channel XLR balanced inputs with 48V phantom power to supply power for condenser microphones.

• Equipped with 2-way 6.35mm inputs, 2-way XLR balanced outputs and 2-way 6.35mm balanced outputs.

• Built-in 10-band EQ for fine-tuning vocal timbre.

• Adjustable gain with a range of 0-15dB.

• Device lock function: manual lock or 10-minute auto-lock to avoid accidental operation.

• 23 user-preset custom modes for quick recall.

• USB port available for firmware upgrade and software control of EQ, presets, feedback and noise reduction depth.

• Display shows the logo and model on power-on, and indicates the status of each enabled function.
