Active Direct Box

One look at our dB10 Passive and dB12 Active Live Sound > Signal Processing > Install Sound > Installation Accessories > Direct Boxes will tell you that these are no ordinary Live Sound > Signal Processing > Install Sound > Installation Accessories > 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.

Utilizing custom dbx mu-metal-shielded audio Install Sound > Install Speakers > 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 the db12 includes 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.
