It's either shelving or peaking. If it's peaking, it will have a bell-shape, whose centre is at the centre frequency, and whose width is determined by it's Q. What that means is that turning down all the EQ knobs will result in a rather wavy shaped EQ curve. If you would just turn the levels down, the curve would stay flat. Ask your friend why he does it. Maybe he has a good reason. It seems odd, but then I have seen odder things where it turned out that there was a perfectly reasonable explanation for them.

Theory suggests it's a weird way to set up EQ, but if the result sounds good then it's being done 'right'. Then again, could it also sound any better done differently... ? I find it near impossible to comment on other peoples FOH live sound work; you never get the chance to try doing it your own way, under the same conditions. It may sound pretty poor out front BUT also be the best achievable in that venue with that kit and those artistes... Then again there are a few people who get nice sound in just about any situation. I guess they are real Sound Engineers. Guy
