อุปกรณ์ปรับแต่งเสียง DBX AFS 224V ป้องกันเสียงหวีดหอนไมค์ Advanced Feedback Suppression® Processor

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.
