dBx by Harman eliminates feedback from a PA system with the AFS2 processor

Available in the Iberian market through Earpro, New dBx AFS2 processor eliminates feedback from a PA system and promotes ease of use for your live sound application, facilities and groups.

The audio processing specialist dBx, belonging to Harman Group (whose products it distributes in the Iberian market Earpro) Its new AFS2 feedback suppression processor is available, incorporating a wide variety of updated functionalities, as an autoconfiguration assistant, a completely redesigned advanced feedback suppression module and a large LCD display.

Successor to the AFS224, new dBx AFS2 processor offers next-generation feedback elimination, while maintaining its ease of use thanks to the one-button assistant function, that automates key configuration parameters and guides the user through the entire adjustment process. AFS2 has an LCD display, as well as twenty-four LED meters per channel for adjustment and monitoring, and can be added to a sound system in minutes through easy rear panel and optimized front panel connectivity.

AFS2 DSP Module Takes Advanced dBx Feedback Suppression Technology to a New Level (AFS), as it provides faster and tighter filter groups, in both fixed and dynamic modes. While ten and twelve filter feedback elimination processors are common today, AFS2's dedicated processor offers up to twenty-four programmable filters per channel, with quality factors of up to 1/80 octave.

This level of extreme precision, previously available only on the highest-end processors, allows AFS2 to eliminate the exact frequencies necessary to attenuate feedback. Besides, offers application-specific filter types including speech, low music, medium and high.

AFS2 also incorporates selectable fixed and dynamic filtering modes (for installations), Selectable filter release times, Instant filter release and other functionalities, all available through the user interface that is managed from the front panel. Can be used in stereo or dual mode (two independent channels) and has XLR and TRS inputs and outputs, as well as a USB input for firmware updates when available.

As Jason Kunz says, market manager, portable PA and recording & broadcast en Harman Signal Processing, “Eliminating feedback can be one of the most difficult and tedious challenges to face when tuning a PA system.”, especially for groups and performers who have to bring their own equipment and who are more musicians than sound technicians. AFS2 is easy to use, while powerful and flexible enough to integrate into large-scale live sound systems and elaborate fixed installations”.
