how you will label them?
With where the cables plugged into the MixRack’s sockets end.
Since these are sockets already labeled with their socket number it makes no sense to give them different names
It makes a lot of sense for fixed installs where stuff mostly gets plugged into (sub)snakes and the MixRack just lives in a rack in a closet somewhere. Where I work, having sockets named “A1”, “G6”, or “DR13” (or “Drum Riser 13”, if there’s room for that many characters) would be way more useful than just “14” or “33” or “1”.
