    DBX 266XS 2 channel compressor/gate/expander

    The dbx 266xs Compressor/Gate is the latest in a long line of the world's most successful compressors from the inventors of the technology. Its patented Overeasy compression technology provides smooth and musical performance while the AutoDynamic attack and release controls, found only on dbx compressors, puts great sound within easy reach. The 266xs can operate in stereo or dual-mono modes, has true RMS power summing and features quality XLR and 1/4" TRS inputs and outputs. It cuts no corners on visual feedback with gain reduction metering and easy-to-read backlit switches.

    Adding a dbx 266xs Compressor/Limiter/Gate to your live sound rig or studio gives you more dynamic control to help create a more polished, professional sound. Having compression in your audio chain gives you the ability to smooth out uneven levels, add sustain to guitars and fatten up your drums. It also makes it easy to bring vocals to the front of your mix – adding greater clarity and making them stand out from the surrounding instruments

    dbx 266xs Compressor/Gate Features:

    Error proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten up mixes
    New gate timing algorithms ensure the smoothest release characteristics
    Program-adaptive expander/gates
    Great sounding dynamics control for any type of program material
    Separate precision LED displays for gain reduction, compression threshold and gate threshold allow quick, accurate setup
    Stereo or dual-mono operation
    Balanced inputs and outputs on 1/4" TRS and XLR connectors
    Side Chain insert
    Classic dbx "Auto" mode

    DBX DB12 Active direct box w/pad, polarity invert, ground lift

    The dbx dB12 is an active direct box that utilizes custom dbx mu-metal-shielded audio transformers, high-quality Neutrik connectors, and low-noise circuitry. The dB12 direct box includes a pad switch that accommodates instrument, line, and even speaker level signals. Take even more control of your sound by utilizing the dB12 direct box's polarity invert switch to set the phase relationship between the direct and mic'd sound.

    As a professional, you don't have time for interference, so dbx includes a ground lift switch in the dB12 active direct box to solve potential hum and buzz problems due to ground loops. And between the combined shielding of the cast metal chassis and the custom-wound transformer, you can be doubly assured of a clean signal free from interference. All of this sits atop a solid, stable footprint, that will keep the dB12 direct box from being dragged around the stage. Unique contoured underside allows secure stacking of multiple dbx dB12 Active Direct Box units.

    dbx AFS224 Feedback Eliminator

    The dbx AFS224 Advanced Feedback Suppression processor was designed to provide state-of-the art feedback elimination processing, while maintaining a simple and intuitive control interface. From the powerful DSP module to the no-nonsense user interface, the AFS224 provides all the processing and control necessary for both installation and live use. The AFS224 is an absolute must for any live sound application.

    Ten and twelve filter feedback elimination processors have become the de facto standard, but the engineering staff at dbx have never been quite content residing in the neighborhood of the status quo. So, to raise the bar once again, they went out and developed a dedicated feedback suppression processor that offers up to 24 filters per channel with filter Qs up to 1/80 of an octave. To achieve these staggering numbers dbx utilized their patent-pending AFS technology that had previously only been available in the upper echelon line of products and made it available in this stand-alone processor, which takes all of the guesswork out of feedback removal. In addition to the plethora of feedback suppression filters available, the dbx AFS224 also offers selectable modes, live filter lift, and types of filtration, which are all readily available via the intuitive user interface front panel.


    • dbx's Patent-pending (Advanced Feedback Suppression) AFS (tm) technology24 Programmable Filters per Channel - Stereo or Dual Independent Channel Processing
    • Live and Fixed Filter Modes
    • Selectable Filter Lift Times
    • Application-specific filter types include: Speech and Music Low, Med and High
