So, my new Focusrite Scarlett 18i8 has balanced 14" outs, and my rather cheap Fostex monitoring system has RCA inputs.

What would be the best cables that I could make or purchase for such a connection? Right now I have a couple of really cheap T/S 1/4" to RCA cables I bought from Radio Shack probably 10-15 years ago - you know the crappy gray plastic sheathed type that they sold then and perhaps still do today.

Is there a way to take advantage of the balanced jacks when the monitor system is really just +/- with the RCA connections?
