Controller plus a cdj or turntable?

I thought you could run a turntable through the x1 but I don’t own one so I’m not sure. I’ve a Numark N4 so that I can hook up 2 turntables while also having 2 decks for digital. It works seemlessly and I can switch back and forth on the fly and always have 4 decks available if I want them. I’m sure there are several other controllers that do some version of the same thing. Someone else will have to confirm or deny the x1’s capabilities though.
