I finally got one of these yesterday after much anticipation (daisy chains are too buzzy for me). I noticed something, however, that is bothering me and I don't know if they're all like this or mine is just a tad defective. Is the detachable AC power chord supposed to be so loose? I have to hold mine in and wiggle it around for a little to get it to stay put. Not a tight snug fit at all. Sometimes it will start to sag and I will lose my connection...quite bothersome. When it stays it works beautifully but I don't know if I need to take it back and see if others are similar. Another thing is (this may be a real stupid question but) do the DIP switches switch between 9v and 12v? It says that there's an "optional cable" for 18v-24v which I can understand...Maybe I'm dyslexic but I can't find in the manual what the other position that's not 9v is...I would like to run my OCDv4 at a higher voltage but don't want to mess with the switches until I really understand them. Thanks in advance for the help!
