DBX AFS224 Advanced Feedback Suppression Processor 24 Frequency Bands 2 Channels -

The dbx AFS 224 Advanced Feedback Suppression processor is 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.
This dedicated feedback suppression processor 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, 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.


  • Selectable Filter Lift Times
  • 24 LED per Channel Filter Metering
  • XLR and TRS Inputs and Outputs
  • Stereo or Dual Independent Channel Processing
  • Live and Fixed Filter Modes
  • dbx's Patent-pending (Advanced Feedback Suppression) AFS technology
