Excellent Audio Performance for a DI Box at an Appealing Price!

    One look at the dbx dB12 Active Direct Box will tell you that it is clearly different. With it's bullet-proof construction and extraordinary audio performance to rival it's looks, this direct box is a smart choice for a quality, fairly-priced solution.

    Utilizing custom dbx mu-metal-shielded audio transformers, high-quality Neutrik® connectors, and low-noise circuitry preserves the sonic integrity and true characteristics of the signal source. This box includes a pad switch that accomodates instrument, line and even speaker level signals. Take even more control of your sound by utilizing the polarity invert switch to set the phase relationship between the direct and miked sound


    As a professional, you don’t have time for interference, so dbx included a ground lift switch 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. The dB12 features a solid, stable footprint that will keep the box from being dragged around the stage, and the unique contoured underside allows secure stacking of multiple units.
