Lets' clarify since Bucwheat is still unclear on a few things.
(please excuse drifting, I have two tasks that I am monitoring)
Issue 1: DMX fixtures vs non-DMX fixtures:
A DMX fixture is a fixture that is DMX capable. In order words, it can be directly controlled via a DMX controller, such as the much recommended DMX Operator 192. Fixtures of this nature get plugged into the AC for power, and another cable goes in(typically a 3-pin 120-ohm XLR cable). Typically, most DMX fixtures have a DMX OUt to pass the signal along.
Non-DMX fixtures would be your basic Par Cans and most Hi-Tech effects listed on the ADJ site. You know they are not DMX fixtures because ADJ does not say they use DMX. This is where dimmer/relay packs(here-after referred to as dimmer packs) come in. You can assign a fixture to a channel on the DMX dimmer pack. This allows them to be turned on and off(in the case of hi-tech effects) or anything from off to on for things like Par Cans.
Issue 2: Controlling those ParCans:
Usin dimmer packs, you assign DMX channels(in a block of up to 4 typically) by programming your dimmer pack. It's easy.
Then, using your "scanner" button(each scanner button represending 16 DMX channels), you can do the math to see where you need to go to control you device. So, if you put your DMX dimmers starting at 33 and you have 4 of them,, and each taking up 4 unique channels eachm you'd need to go to Scanner 3, and then you can use the DMX Operator Faders to control them. Plug a Par64 into "channel 1" on the first programmed DMX dimmer pack(the one starting at address 33), and Fader 1 on Scanner 3 will control that.
Trust me, it makes more sense when you start doing it. It's not that complicated. You're just starting from nothing. You'll get into it and say "wow, that wasn't that hard.", and it's not.
Also, next time, don't "alternate" bulbs for your Par64's. They are UL approved for the type of bulbs explicitly recommended for them. Any alterations could result in a fire and a BIG lawsuit that you'd have to eat(bring lots of condiments, you're gonna eat it for millions if something happens). Also, consider your wiring in series: if one goes, they all go. Big risk. not wise.
Some re-cap: DMX fixture still draw operational power from AC. They are controlled via DMX. Non-DMX fixtures will need a dimmer pack(which also providers them with power) because the DMX dimmer pack is plugged into AC.
Not to parrot Jingles, but talking with him, I've gotten plenty of good ideas. Why not consider spending around the same money and going DMX LED Pro Par64's? Between the dimmer packs and Par64's, gels and the other stuff, I think you'll come out ahead. And you can throw in the DMX Operator 192.
Here's my numbers:
A Par64 costs say $65. Getting 16 of those = $1040. Ouch(sorry, tax joke).
Now, assuming you get 4 DP-DMX20L's, which I paid $180 for each, that's an additional: $720
$1760 total, EXCLUDING the DMX Operator 192, tax and shipping as applicable.
Now, I think you'd probably need LESS going with the LED Par Can Pro's because they do color mixing, so let's assume HALF the numbers,
First off, lose the dimmmer packs, they aren't needed now.
Second, I see them retailing for $300.
OK, well, $300X8=2400, which is what I'm budgettng for my lights. Put perhaps knowing the SIZE of stages you intend to play might help. You don't need TONS of you're hitting larger zones. But then again, with the higher price, you get lower current draw, decent output and no circuits popping. Seems win-win except for the financials portion. I'm sure for your back-fill, you could find other fixtures to satisfy the requirement. Just depends what you need to do and how your stage show is.
Other issues to think about:
A DP-DMX20L's maximum draw is 15 amps, with 10 amps per channel. Or, basically, 2 Par64's per channel(assuming 500-watts/bulb). You can easily see that going to be 4000-watts per dimmer, and your dimmer is restricted to 15-amps current pull, which is 1800 watts. What's gonna pop first? The circuit breaker or your dimmer's fuse? Only one way to find out, but I bet it's gonna be the circuit breaker at the venue or any thing you've front-ended your lights with(say, a Furma PL-Plus?).
Sorry, I always answer long. I try to be thorough.
