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
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.
