The power strip from my PC cabinet, plugs into an outlet built into the side of my amp rack directly underneathe the computer cabinet, and this outlet plugs into
this APC UPS
The UPS is plugged into another power strip mounted to the side of the Rack case, and then has a
Flush Mount AC Inlet mounted to the side of the case as well. I take a electrical drop from here to the wall.
As for my powered speakers, the cables are cable tied together, and of the same length, and my entire show is configured to connect thru one power drop. Both connections are right there, and can only be plugged in one way. I consider this one "Drop" per speaker, one drop for power.
Technically, I would also run extentions from the power distribution block to the mixer for speaker connection.
Anyway, in the door, it takes me all of 5 minutes to setup sound and begin to play.
