Description
dbx AFS2 Advanced Feedback Suppression Processor with Full LCD Display
The dbx AFS2 is a precision feedback suppression processor designed for studio tracking, mixing, and broadcast applications where problematic resonances can compromise recording quality. Its intuitive LCD interface and real-time metering enable you to identify and eliminate feedback-prone frequencies with surgical accuracy, while the dual-channel architecture processes stereo sources or two independent mono feeds—ideal for multi-mic setups, room ambience captures, or parallel compression chains that need protection.
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 for pinpointing rogue resonances. Application-specific filter types for speech, music low, music medium, and music high streamline session workflow without manual curve design, and Live and Fixed Filter Modes let you toggle between adaptive real-time suppression and locked static profiles—useful when tracking dynamic sources or protecting pre-recorded material during post-production.
Metering & Connectivity
Setup and real-time monitoring integrate a full LCD display paired with 24 LEDs per channel for visual confirmation of active suppression bands. The unit features rear panel XLR and 1/4" inputs and outputs, switchable +4 and -10 dB operation to integrate seamlessly with your console, interface, or outboard chain, and a USB port for firmware updates.

At a Glance
The dbx AFS2 delivers surgical frequency control across two channels with 24 precision filters per channel, making it a smart tool for home and professional studios that track live sources, podcasts, or acoustic instruments prone to room feedback. Its application-specific filter presets (speech, music low/medium/high) and switchable Live or Fixed modes let you suppress problem frequencies transparently while preserving mix clarity, and the full LCD display with real-time metering means you can dial in settings by eye rather than ear. Choose it when you need reliable, automated feedback suppression without introducing artifacts into your recordings.

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.
