NS0202B Professional AI Intelligent Feedback Suppressor

This device is a professional 2‑in‑2‑out digital noise reduction processor. Equipped with an enhanced digital processing chip and AI‑powered intelligent noise‑reduction technology, it delivers brand‑new pure‑voice speech performance. Dual output channels support one‑touch switching between mixed mode and parallel mode. Fitted with a 2.0‑inch IPS touch screen, it allows programming and debugging without a computer, enabling on‑site staff to complete installation and configuration effortlessly. It is compatible with scenarios where two sets of daisy‑chain conference systems operate simultaneously.

Featuring deep‑learning‑based AI noise reduction, the unit intelligently recognizes conference‑site acoustics, accurately separates human voice from ambient noise, and effectively eliminates background noise and sound from on‑site loudspeakers. Built‑in AFC adaptive feedback suppression adopts a high‑speed floating‑point digital signal processor to automatically detect and process feedback frequencies according to venue conditions, improving microphone pickup performance and sound quality.
