The PDBâ„¢ Passive Direct Box is a rock solid, 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. The PDBâ„¢ also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer. Applications: Electric guitar and bass pick up output signals – The high impedance signal from a guitar or bass guitar pickup is translated by the PDBâ„¢ into a low impedance balanced signal required by mixing consoles. Keyboards and line level signals – The PDBâ„¢ 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 PDBâ„¢ can be used to replace individual direct boxes. Simply send the output of the instrument amplifier to the PDBâ„¢ and then to the console (instead of a separate DI box for each keyboard). 3. DJ console output signals – DJ mixers often supply only an unbalanced -10dB signal. The PDBâ„¢ 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. 4. Speaker level signals – The PDB'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.
