Hopefully the packs will contain some 6.0kw dimmers, as you cannot hookup up a 5kw fresnel to a 2.4kw dimmer !.If you are interested there is a guy selling some colortran dimmer packs pretty inexpensively that will do this (around 400 bucks) carlosanddiane at hotmail dot com is carlos email address. You can mention my name, I was looking at one of his 12x2.4 units and I know he has a number of 6 by 100 amp bates
In use of them, open up and inspect the tension and gapping of all plugs on or all cable feeding them. For some reason if using the more or less standard 60A stage pin plug to feed such a fixture, they constantly are getting loose set screws at the plug. Once a year all such plugs need re-torquing even if in theory against code to do, it's necessary. Due to the load, the conductors feeding the plugs expand some under the set screws and re-settle after expansion thus you now have loose plugs. This especially if using "Union" brand plugs, but common to all. Check the tension on all wire to screw terminals - they loose you now will most likely will have a melt down at the plug. (I have lots of examples of this condition on my wall of shame - the plugs will even melt together.) Not just a question of if you didn't wire the cable, it's not to your specs, even if you wired the cable it might after heating up not be to your specs. Where possible, open up all cables and plugs and test the torque of the set screws. Normal electrical practice does not allow or recommend that you re-tighten stuff such as circuit breakers... don't care, in this case it's I believe 20 inch pounds of torque that's required, verify it if you have time and or at least do a sampling of what you have or get before using it. If what you test complies, fine, if what you have does not, be cautious - might not be you that wired the stuff, but it is you responsible for making it work in the end.All, thanks for the great info. I'm already a bit over budget this year (mackie crapped out so had to buy a new sound board) so this is on top of that. I'm hoping to get a go ahead tomorrow and will start following some leads. Any more comments on using them (or how useful they are) still appreciated.
