dbx AFS2 Advanced Feedback Suppression Processor with Full LCD Display

In this review of the dbx AFS2 Advanced Feedback Suppression Processor, the bottom line is simple: this unit is for audio professionals and venues that need reliable, hands-on feedback elimination with clear visual control. The AFS2 stands out because its full LCD display and interactive Wizard reduce setup time while offering deep control through up to 24 programmable filters per channel, making it a practical choice for small houses of worship, live venues, and rental rigs that need fast, effective feedback control without sacrificing sound quality.

Key Features

• Full LCD display: The bright, legible interactive display makes navigating menus and adjusting settings straightforward even in low light, saving time during setup.
• AFS2 Wizard: The built-in Wizard guides users through room setup and automatic filter creation so operators with varying skill levels can achieve effective suppression quickly.
• 24 programmable filters per channel: With up to 24 filters available on each channel and dedicated LED metering, the unit can remove multiple feedback peaks while showing which filters are active.
• High-resolution filter Q: Filter Qs up to 1/80 of an octave allow narrow, surgical cuts that tame feedback without overly degrading tonal balance.
• Flexible I/O: XLR and 1/4 in TRS connections mean the AFS2 can be integrated with pro mixing consoles, powered speakers, and stage boxes using the most common cable types.
• Input signal metering: Five-segment LEDs per channel plus a red clip indicator provide fast visual confirmation of input levels during setup and operation.

Who It's For

The AFS2 is aimed at audio engineers, venue managers, and rental companies who need an approachable but powerful feedback suppression tool. It is particularly useful in small to medium-sized live rooms, houses of worship, and fixed-installation environments where multiple feedback sources appear and quick recovery is essential.

Less-suitable audiences include hobbyists with minimal signal-chain complexity who may not need 24 filters or professional I/O, and very large touring rigs that require networked, multi-zone processors with broader system integration features beyond a single stereo processor.
