Hello. Just got my new mixer through the door the other day, and in setting it up, i have a problem whereby the VU display doesnt display any lights when any music is playing? The power light in the middle is on, but the L and R lights dont display a thing. I have fiddled with just about everything, and cant find anything anywhere to help me out. Was wondering if anybody has had the same problem/knows how to sort it out? Much apprecaited
