DBX DB12 Direct Injection Box - Active DI

One look at the DBX dB10 Passive and dB12 Active direct boxes will tell you that these are no ordinary direct boxes. With their bullet-proof construction, and extraordinary audio performance to rival their looks, finally there’s a direct box worthy of the dbx name. The highest quality components and meticulous craftsmanship make a difference you can hear

Overview

• 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. Both boxes include 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 mic'd sound.
• As a professional, you don’t have time for interference, so we’ve 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. All of this sits atop 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.
• So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx dB12 is for you.
