I recently purchased the Pioneer DDJ-SB, as soon as i got it i set everything up on my laptop which holds all the right requirements to run Serato DJ Intro. Ive tried multiple headphones and all the same result and they all work fine on my Novation Twitch controller, my back up. All my levels in the Setup menu are up but i cannot select cue gain because its not highlighted and i can't select it to adjust it. Do i need to send this bugger back and look for something else? I also get a steady static type feedback from it out of the speakers via the master out....... Some one help please!!
