I'm just starting to make my own cables, so pls bear with me. I'm trying to make a dual rca -> male xlr 'Y' cable to run my Turntable outs(dual rca's)->GTQ2 pre(single xlr male)->MPC 60 record in(single trs input). I'm using mogami 2 conductor cable, but wanted to know if this is even possible with the cable I own, then I was going to buy the connectors. Would I connect one wire and half the shield to one rca and the other to the other rca? Where would the corresponding connections be made on the xlr connector? Thanks in advance.
