Congratulations! You are thinking like an engineer! A simple expression confuses you, but you cover that up by saying it can mean a lot of things. A non-engineer would have probably said something like "Oh, aitch-oh, like the model train gauge! Good one!"
If you meant 'High Output', it wouldn't apply to this thread, would it? You never wrote what you meant, so FO. I hope that doesn't confuse you. :D
