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 O instrument input, 50k O parallel link jack, a 600 O 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. Electric Guitar and Bass The high impedance signal from a guitar or bass guitar pickup is translated by the unit into a low impedance balanced signal required by mixing consoles. Keyboards and Line Level Signals Automatically balances and matches the line level outputs of modern electronic keyboards. If using a multiple keyboard setup and the keyboards are all plugged into a single instrument amplifier, the dPDB can be used to replace individual direct boxes by simply sending the output of the instrument amplifier to the dPDB and then to the console. DJ Console Output Signals DJ mixers often supply only an unbalanced -10dB signal. The dPDB converts this signal to a balanced line level signal before it reaches the console, while providing a convenient method of connector transition with the capability to run long cables. Speaker Level Signals By accepting speaker level inputs from a power amplifier's output, the DI allows post-amplifier, post EQ and effects signals to be fed directly to the console. In this manner, a particular effect or amplifier sound can be sent directly to the mix.
