Ten and twelve filter feedback elimination processors have become the de facto standard, but the engineering staff at dbx has developed a dedicated feedback suppression processor that offers up to 24 filters per channel with widths as narrow as 1/80 of an octave. To achieve these staggering numbers, dbx utilized its 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.
