This product is a professional digital auto feedback suppressor (4-in-1-out) , designed for high-demand acoustic environments including conferences, theaters, auditoriums, classrooms, and multi-purpose halls. Featuring advanced adaptive filter technology, it effectively eliminates howling before acoustic feedback occurs, delivering up to 12dB of additional gain margin. Key Features Adaptive Filter Technology The adaptive filter can switch between "Fast" mode and "Precision" mode: Fast Mode: Ideal for applications with frequently changing microphone positions, such as conference systems with multiple microphones that are switched during use Precision Mode: Ideal for fixed microphone positions, such as lecterns with stable acoustic environments The adaptive filter converges at a slower speed to effectively suppress more reflected components. Built-in Automixer Features a built-in automixer for two microphone inputs. When two microphones are used to capture a moving speaker, the automixer: Automatically reduces gain on the microphone with weaker signal input Automatically increases gain on the microphone with stronger signal input Tracks the moving speaker for optimal speech clarity Maintains constant total gain to preserve maximum feedback margin The automixer function remains operational even when the feedback suppressor is disabled.
