[QUOTE="Dan Mortensen, post: 121017, member: 2826"] Re: ESD Hi All, About a hundred pages ago I mentioned that a friend of mine had a Midas Pro 3 with stage box at his work, and that Midas had sold them UTP Cat cable for the interconnect. When we had the X32 issues with ESD (electrostatic discharge, what you get from static electricity) while using UTP but no issues with STP, two separate Midas company people who claimed to know told him that UTP works fine with Midas consoles and UTP was all they sold. There was no reason to use STP, they said. Further discussion ensued here which I won't attempt to summarize, except to say that we heard from someone who might be knowledgable about such things that maybe Midas had never tested their products for ESD. It will be worth noting that Midas does their interconnect differently than Behringer. You can have two parallel runs of CAT cable between the console and stage box, with one in use and one redundant, just in case. He thought there was an automatic switchover between them in case of a problem, but yesterday he tried pulling the active one and there was no auto-switch, he had to manually do it and it took a few seconds, about as long as it takes for the X32 and S16 to do their handshakes when first connected together. He swears he saw it auto-switch before, and thinks a menu setting may have gotten changed somehow but in two minutes of looking he couldn't find it. FWIW it's a very pretty console. Today we found time in the empty theater to connect up his system with the UTP (he had installed Ethercon-terminated STP in conduit for his install, and the reels of UTP were extra and unused), with the cable running down aisles. I took my sparker so we could zap it. We had music going from the console to the stage box, and a Q-Box letting me monitor sound output at the stage while not endangering any speakers. Sure enough, with only one run of UTP connected between console and stage box, it was easy to disrupt the signal with the UTP. Maybe not quite as easy as with the X32/S16, but not that much different, the music still went off. It definitely is disrupted more gracefully than the X32; there is no burst of white noise like there is with the X32, it is just quiet until the disruption passes. He said all the input meters maxed out during the disruption, but I didn't hear anything on the Q-Box. Having the UTP as the active run and the STP as the run-in-waiting made no difference. Having the STP as the active run and the UTP as the run-in-waiting took maybe a little longer to be disrupted, but was still eventually (5-10 zaps tops) disrupted. Removing the UTP and having only the STP had no disruption no matter how many zaps, and the same with 2 STP runs connected. Maybe this is not a problem because there is not a Midas thread on a forum that is anywhere near as active as this one? Maybe Midas people are luckier than their poor X32 cousins? I have no explanation why nobody's noticed this. But there you are. [/QUOTE]
