DF-2000 is a stereo Feedback Eliminator processor with modes of dynamic search, filter lock and manual. All parameters can be easily adjusted and controlled via the user friendly menu function. DF2000 searches for any feedback frequency and eliminates it by applying the corresponding notch filter just deep enough to suppress the amplitude of the feedback at that frequency. This is a very powerful tool for precise effect adjustment. Detailed Engineering was put into the development of the effects to create quality audio effects. The 24-bit A/D and D/A converters provide superb sound quality and a wide of frequency response due the the 48kHz - sampling rate.
