DBX AFS2 Advanced Feedback Suppression Processor

The DBX AFS2 is the second-generation feedback suppression processor from dbx. Whether you’re playing with your band, a live sound engineer, or audio installer, you know how annoying feedback can be. Using the updated AFS algorithm first introduced in the acclaimed dbx Drive Rack PA2 speaker management system processor, the AFS2 kills feedback dead in its tracks without adversely affecting the tone of your system.

New AFS2 Wizard Function

Not sure how to ring out a sound system? No problem. The new Wizard in the AFS2 walks you through the entire setup and ring-out procedure. Thus, feedback suppression couldn’t be any easier. Specifically, just press the big, red Wizard button and follow the on-screen instructions.

Taken to the Next Level

The AFS2 Advanced Feedback Suppression processor has been completely re-designed and incorporates a new module! With its powerful DSP module, AFS2 provides all the processing and control necessary for both installation and live use.

Ten and twelve filter feedback elimination processors are the de facto standard, but the AFS2 offers a dedicated feedback suppression processor that offers up to 24 filters per channel with filter Qs up to 1/80 of an octave. Above all, the AFS2 now provides the user with a full LCD display setup and monitoring.

To achieve these staggering numbers, DBX utilized their improved AFS technology that had previously only been available in the upper echelon line of products and made it available in this stand-alone processor.

In addition to the plethora of feedback suppression filters available, the AFS2 also offers selectable modes, live filter lift, and types of filtration, which are all readily available via the intuitive user interface front panel.  With all of these state-of-the-art features in place, not only do you hear no evil, but you will now be able to see no evil.
