dB10 Passive Direct BOx dB12 active Direct BOx Product Overview 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. sample application Direct Box Features < 3-Way 0/20/40 dB Pad Switch < Premium Performance < Flat/High-Cut Filter Switch < Rugged Design < Output Polarity Invert Switch < Stackable Chassis with < Ground Lift Switch Durable Rubber Foot < 4-Year Product Warranty < Gold-plated Neutrik® XLR Connector INPUT THRU PAD 0dB < Recessed Chrome Toggle Switches dB12 additional Features 20dB 40dB < Hi-Z ¼" Input Jack < +48V Phantom Powered Operation < Parallel ¼" Thru Jack < Green LED Phantom Power < Transformer Isolated Indicator < Premium Shielded dbx < Low-Noise Active Circuitry Custom Transformer < Balanced XLR Lo-Z Output dbx Professional 8760 S.
