I don't understand the use of DIs that I see with EQs built into them. I have never once played a show using a DI where the sound person didn't have total control over what went through the PA - and even if I did have any control over that, how would I be able to hear/judge what the audience would hear from my spot on the stage. Simply put, how would I use a DI to EQ something I can't hear and is gonna get messed with by a soundperson anyhow? I have a feeling I might be missing something here. Please explain any and all who can. Thanks.
