DI Boxes

The DI box converts an unbalanced signal into a balanced signal. The DI box is used when a signal source with an unbalanced output (usually coming from a jack or cinch connector) is to be connected to a device with a balanced input (usually an XLR connector). Typical examples of unbalanced signal sources are guitars with built-in pickups (electric guitar, electric bass, acoustic guitar), keyboards and other electric instruments or CD players; Common balanced inputs are found on mixing consoles or audio interfaces, for example.
