The PDB 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 PDB also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer. Applications include converting high-impedance instrument signals to balanced low-impedance for mixer connection, and balancing and matching the line-level outputs of modern keyboards.
DJ mixers often supply only an unbalanced -10dB signal. The PDB 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.
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.
