At dbx, when we do something, we do it right. So, when we decided to create our new direct boxes, we didn't just settle for the same outdated approach to direct box design. With our dbx name on the line, how could we? One look at our new dB10 Passive and dB12 Active direct boxes will tell you that they are clearly different. With their bulletproof construction and extraordinary audio performance that rivals their looks, there is finally a direct box worthy of the dbx name. The use of 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 accommodates instrument, line, and even speaker level signals. Take even more control of your sound by using the polarity invert switch to set the phase relationship between the direct sound and the mic 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, interference-free signal. All of this rests on a solid, stable footprint, which will prevent the box from being dragged around the stage, and the unique contoured bottom allows for 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 level on a few stereo pairs, the dbx dB10/dB12 is for you.
