Sabine FBX-901 Feedback Exterminator

Description

The automatic feedback controller is be a single channel digital signal processor with nine 1/10- or 1/5-octave filters (selectable). It may be used on the whole mix, on sub-groups, or on selected insert points. The unit will automatically sense feedback and determine its pitch, then assign a digital notch filter to the resonating frequency to automatically eliminate the feedback. The product will use two types of user-selectable notch filters: “fixed” or “dynamic.” The fixed filters will remain set on the initial feedback frequencies, while the dynamic filters will be automatically reassigned new frequencies as feedback occurs during the program.
