Reply to Distortion Problem

I recently bought a brand new Xone 22 mixer. So, naturally, on the day of it's arrival I plug it in and... everything sounds horrible.

At first I thought it was my CDJ's, because this was my first time trying them out too, but after running my MP3 player into my mixer, I had the same problem, so I checked my speakers (also new,) by running my MP3 player into them. They were fine, so I've now isolated the problem to the mixer. So I check all the inputs, and wherever I plug anything in, I have the same problem.

So, as you might've guessed due to all the new stuff I have, I've literally just started mixing. In fact, I haven't even been able to play anything yet. So, embarrassing as it is, I have little to no knowledge of how to DJ, and as a result, I don't have a clue what half the buttons, knobs and sliders do yet. so I'll admit it could simply mean pressing a couple buttons, but I'm pretty sure there's no gain control knob on one of these things, but I might be wrong of course

ANY suggestions would be greatly appreciated, because I've looked everywhere on the internet for an answer to my problem, but it seems like no-one is in the same boat as I am.

Cheers guys
