dbx AFS2 Advanced Feedback Suppression Processor with Full LCD Display

The dbx AFS2 is a precision feedback suppression tool built for live sound engineers and studio professionals who need surgical control over problematic frequencies. Its intuitive LCD interface and real-time metering make it straightforward to dial in suppression without guesswork, while the dual-channel architecture handles stereo feeds or two independent mono sources with equal effectiveness.

Signal Processing & Control

The AFS2 deploys 24 filters per channel with selectable filter Qs up to 1/80 of an octave, providing granular frequency targeting. Application-specific filter types for speech, music low, music medium, and music high eliminate the need for manual curve design, and Live and Fixed Filter Modes let you switch between adaptive and static suppression strategies depending on your source material.

Metering & Connectivity

Setup and monitoring are handled via a full LCD display paired with 24 LEDs per channel for visual filter activity feedback. The unit features rear panel XLR and 1/4" inputs and outputs, switchable +4 and -10 dB operation to match your console or interface levels, and a USB port for firmware updates.
