All purchases I make are business decisions. When you've spent a quarter million bucks on gear in a lifetime so far(and it's not a long one yet), you have to think many steps ahead.
Using the DMX Operator 192, you can program scenes and chases. I am working on "documentation sheets", which, if printed and placed in a binder, can provide a somewhat quick and easy reference for people to use. You might have to make a "crash course for the DMX Operator 192" for whoever is going to be taking over for you during your period of being inconvenienced by "the man".
As in my case, I am the only one who knows anything since my crew refuses to remember anything from one show to the next. My video guy doesn't know how to run a multi-camera system. My lighting person refuses to make a real effort. My other crew people spend more time goofing off than working. I mean, come on, it only takes 5 minutes to wheel 2 subs on a wheel base 150 feet and then return to get the next, and that's assuming dragging a dead body as well. When I do it, it's like a minute and a half max. Roll it, park it, return for the next pair on it's own wheel base.
So, make whatever business decisions you need to make.
One thing to note about LED fixtures, or really any fixture: The parts for most of these are made in the millions, sometimes tens of millions. Eletronic components, chips, LED's. It's impossible to quality control them all, because then it comes down to an individual thing. Then it becomes impractical and expensive.
Trust me, I know stress. I'm not in your type of situation, but the show must go on. I get the lovely ones like "Oh, and you have a big show tomorrow, I forgot to tell you we contracted for it 6 months ago. Let's get it done." or trying to force a 2 day job into a couple of hours. Or how about having restricted access to a vehicle(1 car) and then having the other person running late, and then I can't get my other business stuff done?
Check your power, check your lighting. Remember, don't put DMX/intel fixtures on dimmer and switcher packs. I doubt that's a problem. I bet your power is. Most clubs have bad power, as do restaurants. Breakers do wear out. You don't know what your wiring is line in the walls, and sometimes it can fail as well. Get an electrician in there.
In the meantime, ADJ does have that 1-year warranty. Have someone box up your bad units or if it's been less than 30 days, maybe the store will take them back. Always save your boxes for at least 30 days, minimum. If it fails, you have a shipping container.
