What Have You

I am trying with great difficulty to hook up a turntable to a Spirit by Soundcraft M12 mixer. I was told I needed a phono preamp, so the turntable feeds into a Rolls preamp, which then goes into the mixer via balanced 1/4" cable.
My problem is that there is an awful hum present at all times only on the channels coming from the preamp/turntable. The turntable does seem to be grounded to the preamp, as I have managed to get rid of a higher pitched humming sound. But I am still left with an even louder, constant hum.
After countless discussions with Soundcraft customer service reps, I have decided that a direct box with a ground lift switch is the next thing to try.
My question is should I be getting an active direct box, as opposed to passive? And do I just connect the phono preamp outs to the direct box ins, and the direct box outs to the mixer ins? Or maybe I don't need both the preamp and a direct box?
Perhaps I am missing something, and I'd appreciate any suggestions. Thanks.
