»Direct Boxes

A DI unit, DI box, Direct Box or simply DI is an electronic device that connects a high impedance line level signal that has an unbalanced output to a low impedance mic level balanced input, usually via XLR connector. DIs are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input. The DI performs level matching, balancing, and either active buffering or passive impedance bridging to minimise noise, distortion, and ground loops. DIs do not perform impedance matching.

DI (pronounced dee EYE) is variously claimed to stand for direct input, direct injection or direct interface. DIs are extensively used with professional and semi-professional PA systems and in sound recording studios.
