User manual ART DPDB

[. . . ] This rock solid, roadworthy DI Box is a dual version of our popular PDB. It allows for the connection of the outputs of electronic musical instruments (or other audio sources) to the balanced inputs of mixer consoles. [. . . ] Keyboards and line level signals The dPDB automatically balances and matches the line level outputs of modern electronic keyboards. If you are using a multiple keyboard setup and your keyboards are all plugged into a single instrument amplifier, the dPDB can be used to replace individual direct boxes. Simply send the output of the instrument amplifier to the dPDB and then to the console (instead of a separate DI box for each keyboard). Suggested setting ­ set the input attenuation to -20dB (line level) or ­40dB (amp level). 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. Suggested setting ­ set the input attenuation to 0dB or ­20dB. Speaker level signals The dPDB's ability to accept speaker level inputs from a power amplifier's output 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. Suggested setting ­ set the input attenuation to ­40dB (amp level). Service: The following information is provided in the unlikely event that your unit requires service. Check to make sure that all cables are connected correctly, and the cables themselves are in working condition. 2) If you find the unit to be at fault, write down a complete description of the problem, including how and when the problem occurs.
