Direct Box (DI Box)

By , About.com Guide

Definition: A small interface box designed for connecting a high-impedance, unbalanced instrument or other device to a low-impedance, balanced microphone input on a mixer or recording device.

A direct box is also called a "direct injection" box, as it allows a "direct injection" of a signal into the PA or recording system, as opposed to going through an amplifier and microphone combination.
Also Known As: Direct Injection, DI.
Examples: "I use a DI box for bass recording in the studio."
