Harman’s dbx is now shipping its AFS2 Advanced Feedback Suppression Processor ($499 MSRP), designed to completely eliminate feedback from a P.A. system. The AFS2 is designed for bands, DJs, live sound and fixed installation applications, and offers upgraded features including a Wizard auto-setup function, a completely re-designed Advanced Feedback Suppression module, and a large LCD display.
Successor to the AFS224, the AFS2 provides state-of-the-art feedback elimination and is simple to use, thanks to its single-button Wizard function that automates key setup parameters and walks the user through the configuration process. The AFS2 offers a full LCD display and 24 LED meters per channel for setup and monitoring. dbx states that the AFS2 can be added to a system in minutes due to its easy rear panel connectivity and its optimized front panel.
The AFS2’s new DSP module provides for 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 exact frequencies needed to attenuate feedback.
