I have some old analog recordings I want to archive into an MR-1000. Given that the old analog players have RCA outs, what is best for connecting to the MR-1000. RCA out to a mixer with RCA/in-out and 1/4 inch mixer outs to the MR-1000? Or is it possible to go direct RCA to MR-1000 with a cable that has RCA at one end and quarter-inch plugs on the other side?
