I think a 1:1 patch with cotrol at the the s5000 is what I’m after. Both the mixracks will have GigaAce in their I/O slots. We’re using Dante for our lobby, backstage, and other distribution. Possibly recording as well. I think I fugured out my own questions tho. So if I have 48ch of input at the DM64 then those would go to the s5000 viat tielines. Then, say I have 16 mixes for monitors, the mix outputs would go back to the DM64 via tielines again and then patched to its outputs. All this digital patching is kinda confusing sometimes.
