Designed to completely eliminate feedback from a PA system, the dbx AFS² Advanced Feedback Suppression Processor is the successor to the earlier AFS²24 and is intended for use by live bands and DJs, and in live sound and fixed installation applications.

It brings upgraded features including a Wizard auto-setup, completely re-designed Advanced Feedback Suppression module, and a large LCD. The one-button Wizard automates key setup parameters and walks the user through the configuration process. The Aall-new DSP module provides faster and more focused filter sets in both fixed and live mode. While 10- and 12-filter feedback-elimination processors are commonplace, the dedicated processor in the AFS² provides up to 24 programmable filters per channel, with filter Qs up to 1/80 of an octave. This level of extreme precision, previously available only in high-end processors, enables the AFS² to zero in on the frequencies needed to attenuate feedback. Once tuned, the unit offers application-specific filter types including Speech and Music Low, Medium and High.

Additionally, the AFS² offers selectable Live and Fixed (installed sound) filter modes, selectable filter lift times, live filter lift and more, all of which are available via the front panel. It can be used in either stereo or dual independent channel mode, and includes XLR and TRS inputs and outputs, and a USB jack to enable firmware updates when they become available.

The dbx AFS² will be available in July 2014, at a suggested retail price of US$499.
