Peter, Christopher, Jim,
Thanks so much for your responses. Each informative and exactly what I was looking for.
I knew the SR gives two discreet channels but didn't know it requires external battery, which would bulk it up mounted on the C100. I was already thinking of using my run-bag waist pouch. I currently stash a long lens, cards, batts, etc in it. I use ThinkTank Photo's Change Up bag, and have it in front. I actually have a MixPre-D that I used when I was back shooting DSLR. If I ran two 401s into the MixPre-D, which output port on the MixPre-D would be best to run from my Change Up waist-bag up to the C100's two XLR inputs? The Tape Out, ST Unbalanced Mic Out, or LR XLR (if I went out of the XLRs, is there a slim, dual XLR cable or minimal snake you might recommend?)
Thanks again!
Chris.
