The Hybrid DB-02 is a professional dual-channel automatic feedback suppressor designed for live sound reinforcement, stage monitoring, and PA systems. Using advanced digital notch filtering, it detects and eliminates problem frequencies instantly — maintaining clean, stable sound without altering tonal quality. The DB-02 is an upgrade from the DB-01, offering faster processing, finer resolution filters, and improved headroom for demanding audio environments.
