I just put my deposit down on my black AV20, but I'm wondering what processing modes it supports. I can't seem to track down a definitive list. Even their website is missing it, as far as I can tell. Obviously DD and DTS, but what else? Also - what kind of balanced interconnects are people using to connect to their amps? I'm thinking of going with wickedcables custom made XLRs. Also - When is the next software update scheduled? Are there cumulative release notes anywhere? The website only lists the last two. One last Also - How do I use the two sub outs with just one sub? Do I need to do this?
