What type of generator/inverter/power conditioning for system
« on: November 07, 2018, 01:24:27 pm »

Hello my name is Steven and im new to the mobile DJ world. I have purchased 2 JBL PRX 818XFL,s (1500 w each), 2 PRX 815w,s (1500 each). Im using a Pioneer DDJ-SX3 and a laptop. Im going to start DJing at events and outdoor events.
I was wondering if anyone can give me some tips and what exactly is the best way to power these bad boys. Iv been looking into 6000 watt inverters so far but have read that they can have issues with high power low frequency subwoofers. Any tips and recommendations would be greatly appreciated.
Thanks!

Hi Steven, so a few things...

To begin with, youíre not actually going to be drawing 6000w with what you bought.  With the way amplifiers work, you donít normally draw advertised power in real-world conditions even with the speakers running full-open.  While power consumption will vary by a number of factors such as playing bass-heavy EDM or not, everything you listed can probably run just fine on a single 20A circuit.  Also, keep in mind that wattage applies more to marketing than actual volume and performance. 

Second, an inverter isnít really what you need.  Youíll want an inverter generator such as a Honda EU product.  I know itís a small difference in language, but if using search engines this will be important.  More importantly, do your locations not have power?  Running a full show of the level youíre talking on only generators is an absolute last resort for me.

Finally, seeing as youíre new to this, do you have the necessary business aspects of your operation in order such as insurance?  Many venues even at the mobile DJ level wonít even let you in the door without it.  Hope all this helps!

Yes i meant an inverter generator im sorry.
Now in terms of efficiency, Is the Honda series really worth the extra $$$ compared to other portable inverters like the Champion 3200 or Predator series? I see a lot of them that are very competitively prices and Honda is near double most of them.
And for the most part i will indeed have power but at some camp grounds and small events I will not have power. I could always just drop one of the PRX 818s while mobile if a inverter generator is a bad idea.
As for insurance, that is my next step coming up but I wanted to have all my equipment first.

It's not theft insurance on your equipment,  it's liability insurance to protect the venue.

Thanks i was really looking into the Champion 3400 watt inverter generator. Its under 1000 dollars and from all the reviews i read it works great. Any objections on Champion vs Yamaha/Honda?

It is much nosier,  constructed cheaper and the outputs get noisy as you approach full load.  Extra caution for non-PFC devices connected to it.

There were some tests done on the Champion over in RV Forum that had scope traces of the inverter line noise.
