Why do people call it a "DI" if it's an output?

The "I" in "DI" is not necessarily for "Input". According to Wiki:

"DI units are also referred to as a DI box, direct box, or simply DI, with each letter pronounced, as in "Dee Eye." The term is variously claimed to stand for direct input, direct injection, direct induction or direct interface."

As referred before the “injection” term is erroneous and came out of popular misspeaking.

The whole notion of it being called "direct" anything is erroneous as well, IMO. Direct box, direct injection, direct input....the fact that there's some sort of circuitry in the middle suggests its hardly "direct". If anything, it should be called a "converter".

Terminology is a funny thing.

Both direct injection and direct input describes the signal and the device that creates it. There is an output on the device for the DI signal.

^^^^ Yep, "DI" refers to the "function" of the jack, not the jack itself, as in "Use the DI out jack to connect to the board....". That's what I've always heard sound guys yell at me anyway.

Now, what's the difference between "flammable" and "inflammable"? :laugh:
 
Is this just a case of faulty language that's repeated in zombie fashion
Yeah, guitarists have been dealing with this kind of thing for what, 60 years now? We all love Leo Fender, but he's not so great on his Italian language musical terms. :unsure: The feature on Fender guitar amps that's referred to as a "vibrato" is of course, a tremolo. The "whammy bar" on a Stratocaster is called a "tremolo" by Fender, but of course it's actually a vibrato bar.
Tremolo = periodic variation in volume
Vibrato = periodic variation in pitch

One company tried to alleviate the confusion.

Now if you'll pardon me, I've got to go unthaw some chicken.

Historically, direct injection is a UK/European term and direct input is a US term.

These terms became “commonly” used in the late 1960’s and early 1970’s.
