The new Helix Stadium doesn't use AES/EBU. Is there is a reason for this decision? I understand you can get a Line 6 Expand D10 for a few hundred dollars but the new Powercab CL's also don't have AES/EBU connectors. I guess we are moving to XLR only? I've been out of the loop for a while and only recently got back. I'm think I might be missing something here.
