[QUOTE="brian maddox, post: 58330, member: 158"] Re: School is in can't believe i'm going to admit this but... very early in my Pro Sound Career i was trying to troubleshoot a buzz in the system and got the hair-brained idea that maybe it was being induced by the neutral somehow. so, with everything completely hooked up and running, i proceed to disconnect the neutral Camlock from the PD panel. thankfully, our PD panel had nice big analog Voltage meters, which proceeded to go all kinds of haywire and so i immediately reconnected the neutral. elapsed time of transgression probably was less than one second, which is the only reason why every bit of our gear didn't go up in smoke, along with my fledging job/career. i never did tell anyone i had done this because it was obvious in hindsight that it was a Very Stupid Thing. While i learned that day that removing the neutral was VERY BAD i never really did know or understand why. thanks to this little demonstration i now totally get it. so thanks once again to the good people of this forum for at least teaching an old dog the reason why he should never DO this new trick....
