DBX AFS2 2-Channel Advanced Feedback suppressor

The dbx AFS2 Advanced Feedback Suppression processor has been completely re-designed to take the foundation of the best selling AFS224 and bring it to the next level. The AFS2 now offers the highly-intuitive set-up Wizard function that takes all of the guesswork out of setting up any sound system in any room. The AFS2 also incorporates a completely re-designed Advanced Feedback Suppression module and 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. Most feedback eliminators only offer 10 or 12 filters, 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. This means precise feedback control without destroying your music's perfect timbre. To achieve these staggering numbers dbx utilized their improved AFS technology that had previously only been available in extremely high-end products. In addition, 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.
