Im a bit confused on if I should buy a 20 amp conditioner or 15. My home runs on 15 - If I get an adapter- will it basically only run as a 15 amp? And the reason I think I'd need a 20 is because I'm going to be using all 8 outlets and the one on the front most likely. All my rack gear will be powered from here. Needadvice soon.
A 15 amp will be fine. Thanks to the lack of power some clubs have I've had to run a 20 space front of house rack that's full, the mixer, and 3 powered monitors off of one 15A power strip and didn't have a problem. So you should be fine.
and don't be fooled by the term "conditioner". It doesn't condition anything. They're all pretty much just glorified and expensive power strips.
