The dPDB passive direct box from ART features two high-quality direct boxes in one portable enclosure. It is a roadworthy DI for connection of the outputs of electronic musical instruments (or other audio sources) to the balanced inputs of mixer consoles and other balanced inputs. It also allows for connection of a music source to an instrument amplifier while simultaneously patching it to a mixer.

The unit features switchable input attenuation, a 50k Ω instrument input, 50k Ω parallel link jack, a 600 Ω XLR output jack and a switchable ground lift. It excels at impedance matching and improving the sound of any instrument plugged into it. Enclosed in a rugged steel chassis, it is designed and manufactured to the highest standards to provide years of quiet, reliable performance.
