Re:Got it sorted...

Should say in Cross user guide not to connect output 3 on U46MK2 to your amp.
Not when your connecting external mixer....no one on here even knew what i was talking about!
So i just ran RCA lead like I always have.....from my mixer to my amp....and thats all i needed to know....so i gave it a whirl....and it worked!
Getting sound now...calibration on turntable(s)=100%....and surprise surprise....no ground hum!
Why couldn't it just say things like that....nice and simple..in the user guide?
