The AFS2 Advanced Feedback Suppression Processor takes the foundation of the DBX's popular AFS224 and add features like the intuitive Wizard function, helping you set up any room without guesswork. With a completely re-designed Advanced Feedback Supression module, plus complete LCD display setup and monitoring.

The DSP module in the AFS2 gives you all the control and processing necessary for installation and for live use. The accepted standard has always been ten and twelve filter feedback elimination processors, but the AFS2's dedicated processor provides up to 24 filters per channel with filter Qs up to 1/80 of an octave. Dbx utilized their improved AFS technology previously available only in their more premium product lines, now making it available in this stand-alone unit.

The AFS2 also offers selectable modes,  types of filtration and live filter lift, all easily accessible from the intuitive user interface on the front panel.

I was skeptical but it works!


I bought this to use with my "acoustic" Celtic band. Lots of instruments with open mics and pickups of varying quality. I'm an old-school person when it comes to managing feedback thinking you should be able to manage with a 31 band EQ but I had become increasingly frustrating trying to eliminate feedback while mixing from the stage while also performing. I finally bought this unit and it worked flawlessly. I could hear a few frequencies on the edge of feedback during soundcheck but once the unit was activated there was no feedback for the entire gig. In fact, I'm going to have to adjust my gain structure because I had more gain available than ever before. FYI: I put this in the signal chain between my mixer and the powered PA which is a Harbinger MuV MLS800 Line Array PA System used in noisy pubs. No monitors were used.

I would buy this product again.


I like this dbx afs2 very much. I bought a feedback destroyer pro and could not figure it out how to set it up to work. This product is very easy to setup and it did solve problem ...thumb up !!!!
