I'm re-setting up my 5.1 system and have a couple questions. I want to make sure I'm getting 5.1 from my DVD player, of course and there are 3 options 1. Optical Cable, 2. Digital Coax cable and 3. Analog L,R,C,S1,S2 Sub. Here's my question - what exactly IS a digital Coax cable? Are the regular old audio cables (L and R) usable for this - just use one of the colors in the coax out)? I just bought a two subwoofer cables so i have an extra one (RCA jack I guess it's called) is this digital coax?
I have misplaced/lost the optical cable I was using which has created the need for me to use another method for now.
