Extraordinary performance for all your DI needs. The dbx dB12 Active DI Box ensures that your audio signal remains interference-free so you can get the results you want. With its custom-wound dbx mu-metal-shielded transformer and low-noise circuitry the dB12 maintains the sonic integrity and true nature of your sound source with no colouration or unwanted noise. A handy ground lift switch lets you remove hum and buzz caused by ground loops whilst a 3-position pad switch means the dB12 is capable of accommodating everything from instrument signals to speaker-level signals. Plus with its robust cast metal enclosure the dB12 is shielded from external interference as well as being able to withstand the demands of live and studio environments. Its contoured underside allows for easy stacking of multiple units whilst a rubber foot prevents the box from moving around.
Premium performance A DI with a difference. The dbx dB12 puts premium signal conversion at your fingertips. This premium box utilises custom dbx mu-metal-shielded audio transformers alongside Neutrik connectors and low-noise active circuitry. The dB12 ensures that the integrity of your sound is maintained along with the true characteristics of sound source. Fitted with a handy 3-position pad switch the dB12 is capable of accommodating instrument line and speaker level signals. You can also use the integrated ground lift switch to eliminate hum caused by ground loops helping to keep your signal clean and clear of interference. When it comes to versatility and sound quality the dbx dB12 delivers. Road-ready construction dbx are renowned for their reliable designs. The dB12 is no different. With a robust cast metal chassis the components inside the DI box are protected from knocks and drops. Plus the nature of the housing adds extra shielding to keep noise and interference to an absolute minimum. It isnt just the enclosure that makes the dB12 a dream come true for rowdy stages and hectic studios. High-quality Neutrik connectors ensure that your connections are solid for the best signal integrity and long life. Plus with its stable footprint and rubber foot the dB12 stays exactly where you put it. You can even stack multiple units thanks to its contoured underside.
