is it possible to use the MAOnPC software to control the jands vista software (with s3 console) via either internal patching of some sort or via artnet?
i`m curious and want to try something
There's 168 hours in a week and I try to work all of them

I believe the website auto generates the e-mail. You may want to check your spam catcher.
The 120 is labeled "short packet". To increase the refresh rate, shortening the packet (rather than sending the entire 512 bytes), should give a substantial increase.

I second the plywood base with rubber feet. Cheap and effective.
I don't bother with the countersink and just use a standard nut (the feet keep the bolt head off the floor).
1 piece of plywood, 3/4" 8"x8"
4 rubber feet (with integral nail)
1 large bolt with nut
1 hole

LEDs are a great choice. However, you are not going to get many for the budget you have allotted. Also, you should give some serious consideration to what you are going to use for a console to drive all of this. To keep it cheap and simple, I would look at the Chauvet Obey line. They are a bit tedious to run moving lights, but for the rest, they are fine. Program a few chases and you are off to the races (pun intended).
Considering the size of the area you are trying to light (dance floor), I would probably go with more lights with less punch. You can get a PAR 38 for under $40 with plug, clamp and lamp. They can hold up to 300 watt lamps, but a 125 will probably do fine. Since the primary colors of light are red, green and blue. I would recommend you go with 12 or 16 lights in groups of 4. RGB and a white or light amber. This will allow you to mix any color you want. The hazer is a must. I would go with a hazer before LED lights. Finally, I would give serious consideration to on of the inexpensive "disco" lights. There are a wide variety of them that will run basic chases. You will not be able to control them with DMX, but you can get a relay shoe box that will turn them on and off from the console.
Tim.
P.S. good luck! Lighting can add a lot of value.

I got into work today and the Technical Director wasn't in, BUT our consultant was. This guy knows detectors inside out, he designs the chemical recipe for smoke (someone has to), also in his spare time, he works in a theater. As far as credentials go, that's as good as it gets.
The news isn't what I expected. Haze and effect smoke WILL set off a detector, especially the more commercial optical types. It seems that they work on deflected light, so it doesn't matter what particles deflect it.
Its so bad that his theater installed a kill switch for the detectors (which is ok if there are people in the building).
So in short, categorically, Bugger!

If only they quoted output and beam angle.

Thanks for the prompt replies. I'll check the cabinet models when I'm back tomorrow. They're JBL also. Big grey cabs with a trapezoidal footprint.
One of the amps has begun to emit loud, intermittent crackling noises (bad caps?), and rather than service them one by one as problems arise, my supervisor has decided to replace the lot. So yes, reliability problems.
The comment about bridge mono was on an amp manufacturers faq (I can't recall which one) and simply seemed to suggest that it was a less than ideal workaround for some situations.
Another question is what the optimum ratio of low to high available power should be. I was just reading "Danger: Low Power" (great article) which suggests that consumption is typically 10:1, but also that the amps, especially the high side, should be significantly overpowered to avoid going into distortion.
Thanks again. I'm so glad I found this site. I have a lot to learn.

Here's a peak inside. As you can see there are 5 horndrivers in the middle and 6 x 8" speakers beside them.
Very handy is the fact that you can "open" the centered horndrivers so you can choose between 7 and 37 of vertical coverage. We work with only one top per side, but when our fame will grow (hopefully..) and we need to cover bigger crowds we can easily hang another top underneath our one and adjust the vertical coverage and have a lot more power...

Ahead of this thread, there is one guy who eared this array set up giving a great comment on what it sounds like, that being said it is able to compete with EAW's......So I can't help but wonder which components they are using...???

Microsoft Virtual PC for OSX runs Windows XP just fine on PPC Macs. This is what I used before I had an Intel Mac. That will run SM just fine.

Peter,
Very interesting comparisons. Mixing amp brands may also need to be addressed by different delay settings to get phase traces exactly correct, it seems.
What does DIM100 Vs. Power 4 ohm mean? Is DIM100 inter modulation distortion?
The Lab Gruppen does a power reversal Vs % on that chart.
Then on the THD chart it does a power reversal at about 1.5%.
Is this due to a limiter that cuts power based on distortion?
|
DIM100 is an obscure test that stresses slew rate. It mixes a sine wave with a square wave and looks for distortion on that sine wave during the square wave edges. This test is generally one that a product either does great or lousy depending on it's slew rate capability, and/or input filtering.
From inspection of the frequency response plots the FP6400 doesn't indicate an overall LPF like the other amps. I suspect even a modest LPF well above the audio band would probably clean up the DIM100 result, but this is just supposition on my part and not proved.
As a circuit designer myself, I never embraced the DIM tests as they involve out of band stimulus signals (square waves). That said I generally favor band passing the audio early in the signal path, so any square waves would be slowed down elsewhere well before getting to my power amp where they could cause mischief.
--------
All amps will have some HF phase shift under load due to protective load isolation series inductance in outputs. IIRC the crown will have an additional wide band delay due to A/D/A.

Thanks for all the input guys, sorry it has taken me so long to reply, only came back a couple of days ago from the frozen North with no internet access.
You have given me much to go on. Thanks again.
