Interesting indeed. Probably the most expensive movie screen in the world! Hahaha

Was just noodling on the idea of pimping my power. As it is now, the whole system and any onstage stuff just goes through cheapo power strips and a conglomeration of different colored extension cords. I tie an overhand knot at the plug junction whenever possible to prevent pullouts. I haven't had any issues with unintentional power disconnects, but there's certainly room for improvement in overall stage aesthetics and reducing trip hazard. I suppose it could reduce setup time if the power scheme was mostly ironed out prior to a show too... which I haven't done. Besides the power connections in the rack, each set up is a figure it out as I go situation.

I'm looking forward to eventually creating a side hustle out of this family hobby. Looking through the eyes of someone who doesn't do this as much as some of you guys, it seems there's value in keeping things simple to deploy & stow and maybe a little in the way of creating a professional image of the entire system. Uniform SJOOW cabling and powerCON's. But really, maybe it's not as big of a benefit as I imagine. Maybe it's just the thought my mind wants to chew on at the moment.

At what point in the game does SJOOW become necessary? I imagine it's required for certain municipality codes and possibly for business liability insurance... But, that's just a guess.

Have a parallel kit to tie my two inverter generators together, 30A output. Put this little box together with scraps and such laying around. Fat 8 or 10g copper, 30a plug, ground fault outlet with weather cover. Used a sample piece of stainless a rep had given me ages ago for the top in case an elephant wanders by.

Well. there was a rabbit hole!
I found a couple of sites about how to do that. I can't verify the accuracy of them but they seem reasonable.

Looks well made

Do you put a grounding rod in the ground or ground to a metal stage or anything? I'm not super up to speed on the use of GFCI's with generators. But, just on logic, it seems to me you could hold the stripped end of the hot wire clenched in your teeth while standing in a salt water puddle with bare feet all day long without getting a shock or tripping a GFCI... if nothing is grounded. yeah? no? maybe so?

Another random thought I had the other day, that I'll toss in the pot for mind stimulation and stewing...

If a hard limiter/Brick Wall limiter is the last thing in the signal chain prior to amplification, couldn't the safety we seek with high-pass filters on subs potentially be defeated? In contrast to having the limiter before the high-pass filter in the signal chain.

You could have the limiter first in the signal chain if you were certain that there's no way anything between it and the amp could ever be diddled with. I wouldn't make that assumption.

If there is a way to determine the order in which they occur within the device used, it seems the safest solution would be to have the High-pass last and the limiter second to last in the signal chain.

Sorry Tom, I completely overlooked this post the other day... Hilarious! I've been meaning to try the same thing.

Yeah, I think that is the most humorous video that Dave Rat has put out!

I guess I'll keep tossing up conversation starters an see if we can't get something started...

Random thought/question I couldn't find an answer to:

Q: Assuming impedance is not a variable and is just a constant 8Ω, if a single sinewave is played through an amplifier at a constant voltage, would adding a second sinewave of different frequency yet equal amplitude as the first change the resultant power (watts) in any way? Same voltage, same impedance... one vs. two sinewaves.

You're the one with the wacky ideas and experiments- you tell us! No offense meant, I admire your excursions into the (semi)-unknown!

No. In order for power to rise voltage and/or current would have to rise, which doesn't happen in this case. All that you'd get with adding the second sine wave is a complex waveform, with no increase in voltage or current. All sound content consists of complex wave forms.

We need to get Seth a girlfriend.......or a dog..

Not only can I not answer his questions.......I usually don't even understand them.

But, we need guys that dig deeper - that's where the innovation comes from. Me, I'm just a user who wants to wring out whatever I'm working with to its very best. Not to mention that whole "old dog - new tricks" thing.

Keep it coming Seth....

Moot in real life because:
Impedance changes with frequency.

Hence the reason we need to look at impedance charts to determine "will this amp do the job if I have X amount of cabs per side".
