[QUOTE="Mike Caldwell, post: 100985, member: 170"] Re: lightning protection for powered speakers A few years ago a swimming pool outdoor music system install I did took a fairly direct hit one night. Both Crown CTS amps were toast and the about half of the connections on the terminal blocks for the speaker lines were burnt / carbonized just enough not to pass signal. All the drivers in the Community R .5's around the pool were fine! Just today I was working at a church that was complaining about noise in the pulpit and lectern mics. Both of the mics were producing considerable frying sizzling sounds, they still did pass audio. Telling them it was odd that two mics have the same problem they said it happened after the building took a direct hit that took out various other things in church as well. When it happened the sound system was confirmed to be powered off. Nothing else in the system has shown any signs of trouble.........yet!!! Depending on the path of entry and how direct the hit is I think it's safe to say there is no such thing as 100% lighting proof protection. Since were on lighting protection what are your thoughts on doing an indoor show when there is a pounding thunder storm right on top of were your working. [/QUOTE]
