I've been happily using my FW1814 for a while. I recently purchased a UA Solo/610 preamp to use with it. This pre's output is an XLR. The FW1814 has unbalanced 1/4" inputs on the back and and two combi jacks labelled "Mic/inst" on the front. What's the best way to hook this thing up? Can I run a balanced signal into the unbalanced inputs?
