DBX AFS2 Advanced Feedback Suppression Processor

This is really amazing! We stuck a mic up against the speaker having set it up and got no feedback! 

The AFS2 Advanced Feedback Suppression processor has been completely re-designed to take the foundation of the best selling AFS224 and bring it to thte next level. The AFS2 now offers the highly-intuitive Wizard function that takes all of the guesswork out of setting up any room. The AFS2 also incorporates a completely re-designed Advanced Feeback Supression module. Best of all, the AFS2 now provides the user with a full LCD display setup and monitoring.

With its powerful DSP module, the 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. 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.


Recently reviewed by Mike Crofts in the latest issue of Sound On Sound magazine, here are a ferw quotes:

“The other thing I noticed about using the AFS2 was that even at volumes well below the feedback threshold, using it made the PA sound better, as all the worst excesses of the room response had been filtered and the result was a cleaner, clearer output”.

“…not only was it possible to achieve much louder levels in the hall, but by pushing the volume during setup to force the system to ring out the worser frequencies, the whole sound became more pleasant, cleaner and less fatiguing for everyone present”.

“…it’s (AFS technology) been my get-out-of-free option on many occasions, and I like the flexible way these new dbx units work, and I certainly like the new user interface”.

“The AFS2 is easy to use, especially with the setup wizard, and buys you considerably more level before feedback sets in, without drastically altering your sound”.
