< begin snippet >
A DI unit or DI box is an electronic device that connects a high impedance line level signal that uses an unbalanced cable with a 1/4" phono plug to a low impedance mic level input that uses a balanced cable and XLR connector. For example, one can connect an electric guitar to a DI box which can then be connected to a mixing console's microphone input. It performs level matching, balancing, and either active buffering or passive impedance bridging to minimise noise, distortion, and ground loops. (DI units do not perform impedance matching.)

I've gotten along without one, but many here use one (or keep one around) for plugging bass into a mixer. I've usually plugged line level signal into the line inputs on my mixer, and it's worked well.
Dec 21, 2007 03:29 am when u record..u record from the mics to the preamp and to the mixer...i only record with mics..and xlr cables that go from the mics to the preamp and the mixer and then to the audio interface..so i dont see the point of a di box..i thins its only usefull when i must connect my own guitar for my recording to sit in the control room and record and have the mics in the playroom..right?
Dec 21, 2007 06:34 am If you're only using a mic to record, then yes. No DI box needed. The offer impedance matching, for going into a mixer board. Often they are used live, when plugging into a FOH mixer, to be able to plug a guitar onstage into a mixer XLR input.
They have several uses in a studio, but if you don't have a reason, then there's no need =).
