Reply to Routing a turntable through S2 or S4 (playing real vinyl records)?

i googled this but couldn't find any answers or solutions to this. Basically I want to use a turntable playing records (as opposed to control vinyl) along side my S2. I'd like to not use a mixer, but instead run it through Traktor as channel deck. I also have an Audio 8 at my disposal.

Anyone know if this is possible with an S2 or S4?

Thanks
