Putting the dbx AFS2 feedback suppressor in your system is like getting sonic insurance for your live sound.

    dbx AFS2 Advanced Feedback Suppression Processor at a Glance:

    • Transparent, precise performance from updated algorithms
    • Eliminates feedback, not your sonic integrity
    • Protect individual mics, groups, or even your full mix
    Transparent, precise performance from updated algorithms

    The dbx AFS2 feedback suppressor boasts dbx's updated Advanced Feedback Suppression algorithm. The AFS2 listens to the incoming signal and can anticipate problem frequencies before feedback even begins. You won't hear it working, and you won't notice any sonic difference with it in your signal chain.

    Eliminates feedback, not your sonic integrity

    With 24 filters per channel the dbx AFS2 feedback suppressor is agile enough to fight horrendous feedback in a busy mix, without degrading your overall sound. Each filter can have a bandwidth as narrow as 1/80 of an octave, which means problem frequencies get zapped with incredible precision. Handy presets for Speech, Speech/Music, and Music make it even easier for the AFS2 to anticipate your program material and do its job transparently.

    Protect individual mics, groups, or even your full mix

    It's easy to integrate the dbx AFS2 into any live sound rig, whether you want to protect a couple troublesome channels or your entire mix. Connect the AFS2 to individual channel inserts to guarantee those mics won't feed back. Put it on group inserts to protect an entire instrument section. Or connect the AFS2 to your main mix inserts or between your mixer and amplifiers to fight feedback across the entire stage. Whether you're mixing monitors or FOH, you'll be glad you have the dbx AFS2 in your rig.

    dbx AFS2 Advanced Feedback Suppression Processor Features:
    • Two-channel feedback suppressor
    • Advanced AFS algorithms respond faster and with more transparency than previous generations
    • Sets up fast and easy in any room thanks to the Wizard Setup mode
    • Easy to manage thanks to its clear front panel display and metering
    • Preset modes for Speech, Speech/Music, and Music for optimized performance in any application


    The AFS2’s all-new DSP module takes dbx Advanced Feedback Suppression (AFS™) to an entirely new level. This new module provides for faster and more focused filter sets in both fixed and live mode. While 10- and 12-filter feedback-elimination processors are commonplace, the dedicated processor in the AFS2 provides up to 24 programmable filters per channel with filter Qs up to 1/80 of an octave. This level of extreme precision, previously available only in high-end processors, enables the AFS2 to zero in on the exact frequencies needed to attenuate feedback. The AFS2 offers application-specific filter types including Speech and Music Low, Medium and High.

    The AFS2 offers selectable Live and Fixed (installed sound) filter modes, selectable filter lift times, live filter lift and more, all of which are available via the intuitive front panel user interface. The AFS2 can be used in either stereo or dual independent channel mode. It includes XLR and TRS inputs and outputs and a USB jack to enable firmware updates when they become available. 
    “Getting rid of feedback can be one of the most difficult and insidious things to deal with when setting up a PA system, especially for bands and performers who have to carry their own PA and may be musicians first and sound engineers second,” said Jason Kunz, Market Manager, Portable PA and Recording & Broadcast at HARMAN Signal Processing. “The AFS2 is simple to use, yet powerful and flexible enough for elaborate large-scale live sound systems and fixed installations.”
