[QUOTE="Ben Gingerich, post: 100653, member: 2579"] Re: lightning protection for powered speakers Ivan, I was deployed for a few weeks and when I came back was told it was after a storm they had their center cluster out in their main gymitorium and the main LR in their youth center. (2 different buildings) Yesterday I used a vibroground and found the resistance to their electrical ground was less than stellar, over 80ohms. So in my understanding if lightning was even close it could cause issues even if grounding was good and raises that possibility if its poor. My thought with the switch was all that your moving when you flip that switch is the hot, nutral and ground are still connected, therefore not adding protection from a switch. I guess I'm looking for something to be added between the outlet and the speaker that will blow up first that's small enough to be safely mounted that high. They are starting an addition in the fall and will put a new danley system in as a part of that. (Designed and installed by a reputable company that I work for occasionally) Coverage and output of the MDs is pretty ideal for the current room and material, other than the need for some frontfills. Thanks weogo [/QUOTE]
