At dbx, when we do something, we do it right. So when we decided to create our new direct injection boxes, we didn’t settle for the same old tired 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 these are clearly different. With their bullet-proof construction, and extraordinary audio performance to rival their looks, finally there’s a direct box worthy of the dbx name. 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 dB10 is for you.Input 1 instrument/line/speaker level Input Connectors 1/4" jack Input Type Unbalanced, RF filtered Insert Impedance 150k Ohm typical Max Input +20dBu (0dB pad); +40dBu (20dB pad); +60dBu (40dB pad) Output (Thru) 1 parallel from input jack, 1/4" Unbalanced, RF filtered Output Connectors XLR male balanced Output Impedance 150k Ohm typical Max Output 0dBu Transformer Custom dbx mu-metal-shielded Frequency Response 20Hz to 20kHz, +/-2.5dB Noise <-105dB unweighted, 22kHz BW THD <0.01%, 20Hz to 20kHz BW; <0.005%, 1kHz Dimensions 5.82" L X 5.44" W X 2.20" H (148 x 138 x 56mm) Unit Weight 1.4 lbs / 0.65 kg
