I want to go from a tape deck (rca jacks, left and right) to my MicroTrack (trs jacks, left and right). I looked on NewEgg.com, but I can't find the appropriate cables to do this. The closest thing I could find is a cable that has 2 male RCA jacks on one end and a single 1/8" male jack on the other. What I want is a single RCA jack to a single trs, and I want two of them. Is this right? Please help....
