Bullet proof Pangolin ?

Beware the adjustment on a LM358 set in a gain circuit for modulation. I had it set....I thought.....to a low enough point. It heated the green signal lead going to the FB3 ! It was drawing wayyyyyyy tooo much to trigger the output!!! Lucky for me I didn't kill anything. Watch out on your home built modulation circuits. Just a note to say how well the Pangolin products are made. They have compensated for the accidents it seems.. Bill covers about all the bases!! DAC chips are fine......even though I made one of them very angry.

What circuit were you using,

Sounds like you had something wired incorrectly!

Were you using like 38guage wire? You can put 10A through the wire that comes with the FB3 with no problems at all! In fact, my SDL820 Driver uses 22Ga wire for the 10A and 5A circuits. I believe that there would be much worse problems if the wires were getting hot, perhaps they could have been sitting on something hot or had hot air blowing on them.

My FB3 crashes every time I fire my fogger :-( It doesn't like power supply noise at all, it seems. Poor thing :-(

I had the same problems with an EasyLase and my cheap old 30 EUR fog machine.
Since I have my new Antari fogger nothing ever crashed.
You can either try to connect the power supply of the fogger to a different phase
or go and buy a new one. (Buying cheap means buying expensive in the end :D)

Hi Heroic,

We would like to explore this further and find out what is happening, and if there is a way to solve it. We have plenty of bulk decoupling on the FB3, so this really shouldn't be happening. It makes me wonder if you have some kind of "coupling" going on there, and that's what is causing the problem.

If you could contact us, and send a written description of the system, along with a few pictures of the entire setup and how it is wired, we will ponder it and get back to you.

Best regards,

William Benner

Well, I put a scope on the power rail of the FB3, and it looks like the fogger is just injecting a whole bunch of filth on there. I'm not surprised the FB3 is crashing- it's not reasonable to expect it to do anything else. The fogger's filth is also managing to get past the input filters on my Mackie SRM350 sound reinforcement monitors, so you can see, it's not a problem with the FB3.

I'm not really sure what to do about this other than "buy a better fogger"... I tried snap-on ferrites and that didn't help. Still, I got this fogger from a friend for $50 so I'm not *too* bent out of shape that it doesn't work well.

Hi heroic,

I might be talking out of my rear end here, would a plug-in surge protector help on the fogger power lead ?

Hi Andre,

I tried it, but it didn't help very much- whereas the fogger was causing the laser to go into STOP mode every time I hit it without it, with the surge protector it was doing it about one in three times- which isn't really good enough.

Foggers, Dry Ice machine, bubble machines and so on MUST BE on another phase of distro box or at least on another breaker then all computerized gear.

I second that. I owned a few Chouvete/American DeepJunk (AKA American DJ)
now they are a pile of metal. My Z1500 Antari (Actually 2 of them) still works like a clock and never gave me any problem except....controller board power connector has melted after all that abuse. So I had to put another one. If your Antari start to smell funny you'll need to replace that connector.

Not always practical, especially when I'm running from a generator.

The computers are all laptops, except for the storage server which usually doesn't come on the road with me, so they're not affected by this; the audio gear is all based around DSPs, MOTU 828 mk3s to be exact, but they're not affected either. The only things that seem upset are the Mackie SRM350s (which emit a loud FARRRRT when I fire the fogger, but of course don't crash) and the laser, which crashes. The EasyLase doesn't seem to have a problem, but then I do have it running off a rather nice SMPS which helps immeasurably.

The odd thing is that the fogger used to be fine, but now doesn't do so well. I suspect the cheap motor in the pump is dying... I wanted to get a good hazer anyway- any recommendations?

Never had any problem running my gear of anything... gens...distros... wall plugs and even entire setup on 1 plug..(Had to replace a breaker from 15 to 25 amp) Nothing crushes. No noise nothing. You probably need to reinvest into some good quality products. Can I say...hmm professional gear. :p

You can't get more professional than Mackie SRM350s.

It's the fogger- it's totally broken. I think the motor is sparking internally.

I had a pair of Behringers, but they blew smoke rings when a Douchebag DJ (tm) clipped hard all the way through a two hour set. The SRM350s seem to be immune to all known forms of abuse!

Actually "Beah"ringers are used as a stools or as a stands now days. They well know to catch fire. This includes their entire range of products.
Mackie SRM350s are actually entry level China made mobile DJ stuff for small venues.

Mine were made in Italy- I use them as monitors. I have a pair of SRM450s for the main sound at gigs (and I have a kickass-a-hedrotron Mackie sub too :) )

Actually for my "some time" in industry I've never seen anyone using Mackies.
It's always the same company....with 3 character name:cool:

really? I see mackies using being used a lot as monitors.. JBL's are the main speakers though.

Pretty much every club in San Francisco uses Mackie SRM450s or the bigger ones whose name I forget as main speakers. There are a few that use JBLs, but the indestructibility- as well as improved sound quality of the SRM450v2 speakers- have tended to select against the more fragile JBLs.

Man, we must be spoilt here then.. most of the bigger clubs here are Nexo, :D

I can't see them lasting long when some douchebag DJ blows a bunch of clipping through them at maximum power :/

Just about any factory made speaker is a sad mix of cheap short-cuts and compromises. Build your own! Make them so big and heavy you have to assemble them in place and you can never move them! :D

Oh yeah, that's gonna work really well for my portable PA.

Those need external amps, which means we need at least another flight case of gear... big nono when we already have all this laser stuff to move around!

I also can't see them putting up with being dropped down stairs, off loading docks, and (on one memorable occasion) out of a window without breaking.

Sometimes physical design really matters :)

I have been a speaker designer since about 1980. It is one of the very reasons why I know about audio... sound cards... using sound cards to measure speaker system componenets... LaserBoy.

I have some stuff in my head. I want to make a set of objects that can each be easily carried by a single human unit to make a big stack of not-so-heavy-objects to become a nice REAL line source array; with physical phase alignment; built in class D amps, active crossovers, tri-amp system. BLOW YOUR F***ING BRAINS OUT with very low distortion.
