Feedback Eliminator

1/80th-Octave Filters. Live Filter Lift function.

DBX AFS224 Feedback Eliminator

Advanced technology and extremely narrow, 1/80th-octave filters put the AFS224 at the head of the pack! The concept of the Feedback Eliminator is not new but it took dbx to make it this musical, and usable for all pro audio applications. Where other Eliminators feature filters as wide as about 1/10th-octave, or increase the size of their filters the deeper they cut, the AFS adaptively changes the filter Q using as few filters as possible which makes more filters available to remove new feedback. Now your mix will retain all of its punch and sparkle - without the feedback! Live Filter Lift automatically handles feedback reduction, plus all filter resets. Add the AFS224 to your live rack & eliminate feedback problems!

XLR and TRS Inputs and Output

The AFS 224 Advanced Feedback Suppression processor was designed to provide state-of-the art feedback elimination processing, while maintaining a simple and intuitive control interface. From the powerful DSP module to the no-nonsense user interface, the AFS 224 provides all the processing and control necessary for both installation and live use. The AFS 224 is an absolute must for any live sound application.

Ten and twelve filter feedback elimination processors have become the de facto standard, but the engineering staff at dbx have never been quite content residing in the neighborhood of the status quo. So, to raise the bar once again, they went out and developed a dedicated feedback suppression processor that offers up to 24 filters per channel with filter Qs up to 1/80 of an octave. To achieve these staggering numbers dbx utilized their patent-pending AFS technology that had previously only been available in the upper echelon line of products and made it available in this stand-alone processor, which takes all of the guesswork out of feedback removal. In addition to the plethora of feedback suppression filters available, the AFS 224 also offers selectable modes, live filter lift, and types of filtration, which are all readily available via the intuitive user interface front panel.
