Thanks Terry,
We tried a couple of different things, we tried running my controller through the club mixer, the volume of the controller and the mixer was maxed out but still nowhere near the levels of the CDJs, we then tried using a lead that meant the speakers were going directly into the controller and the same result, all levels were maxed and the output was still not near the output levels of the CDJs, you said there is an output setting on Serato Intro? I am not familiar with this where can i locate this? The gig is tomorrow night so i am running out of ideas!!!
Thanks for your help
