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 performers 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.

Frequently Asked Questions
Can the AFS2 handle both stereo and mono sources?
Yes. The dual-channel architecture lets you process a stereo pair or route two independent mono sources through separate channels, each with its own 24-filter set and independent control.
What are Live and Fixed Filter Modes, and which should I use?
Live Mode uses adaptive filtering to track and suppress feedback as it happens; Fixed Mode applies static, pre-set suppression. Use Live Mode for unpredictable sources like open mics, and Fixed Mode for consistent material like backing tracks or studio recordings.
Does the AFS2 work with both line-level and instrument-level signals?
The unit features rear panel XLR and 1/4" connectors and switchable +4 dB and -10 dB operation, allowing you to match both professional console levels and home studio or instrument interface levels.
What connectivity and metering does it offer?
The AFS2 has a full LCD display for setup and monitoring, 24 LEDs per channel to show which frequencies are being suppressed in real time, XLR and 1/4" I/O, and a USB port for firmware updates. It ships with a standard IEC power cable.
Does it include preset filter shapes, or do I have to design curves from scratch?
The AFS2 includes application-specific filter types for speech, music low, music medium, and music high, plus a Wizard Setup function to automate initial configuration—eliminating the need to manually design curves for most common sources.
