Using Real vinyl with Cross Pack

Hi
I hear people say u can use real vinyl in a mix with Cross Pack but when i put a real vinyl on nothing plays.
Can anyone simply explain how you can without changing all the wires over if there is a way.
I have something about "Bypass" is this in CrossPack?
Thanks and sorry if this is a repost, in searched but didnt find anything
