DISC dbx dB12 Active DI Box

Full Description

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 isn't 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.
