Are you sure the dip switches and the dial aren't both used, for example, the dip switches to set the 10's and the dial to set the 1's? As for this problem it sounds more like a person problem than the
dimmer itself, it should
tie in perfectly, chances are: They haven't patched it to the right
channel on the
console. Schools systems are constantly being used by different people. 7 years ago someone could have come in, knowing what they were doing, and set up a patch that was never questioned. then when you come in they might not even be aware you can patch from the
console As far as they are concernd, when you
plug it in there, it is
channel X on the
desk, even though it may be going to
channel Y on the
dimmer. I was helping at a school end of last year, (Brand new gear, the school is about 7 years old) they had just had a brand new Jands Flexi-Patch put in, I went in there and there were cables all over the bars, when asked they said that most of the patches numberd on the roof, didn't work, I said, okay then, we went through it, turned out that 2 of the patches had the wrong stickers on them, (The electrician's fault) and all the others just happend to be problems happeng with channels 9 & 6... As you can guess, they were reading them upside down.
If you are daisy chaining them together, (as I suspect is the case) the output of the
dimmer you are piggy backing into could be broken, therefore the signal isn't going out. Those are the two things I would check first, if that doesn't work, come back,
Hope this helps
