[QUOTE="Brian Wynn, post: 6244, member: 113"] The System consists of a Behringer X32, 2 Behringer S16 digital stage boxes, 150' of Horizon Duracat Cat5 cable. Rewind back to a cold New Years eve night Dec. 31 2012. We had a double stack JBL VRX system powered by a pair of Crown XTI6002 power amps. Providing for one of our regular bands in a ballroom at a local hotel that we had just spent the week prior to that with a large christian group in the same room. The system we provided the week prior was almost the same system but with a analog Ramtech snake system. We loaded in around 5PM on NYE and I decided to try our new Behringer S16 stage boxes that we just received. This decision was made based on the current floor plan of the room it forced us to run the snake overhead and the Duracat cat5 cable would be much easier to fly than the 54 pair Ramtech. Everything went smooth as usual and we had our setup completed with in 45 minutes. Once FOH was set I decided that we should take a listen to the system before the band arrives. When I walked up to the desk I placed my hand on the lower right corner of the desk and ZAP I got shocked by static.
