The GX7. Hands down.

I am unfamiliar with the NX6000. Rumor has it that it's a refreshed iNuke. If that's true, I don't need to know any more. I bought an iNuke, used it for one weekend event (that happened to be run off my generator). I couldn't get any volume (not like it should have been, and not as loud as I could get when I tested at home. I thought it was a bad unit, so I sent it back to the store.

Upon research, the iNukes have a cheaper power supply design. They don't have Power Factor Correction (had to look it up, remembered we discussed it here... viewtopic.php?t=23828)

I now have two gently used GX7s from ebay. I bought each for less than what a new iNuke6000 cost at the time. Looks like about the same cost now as an NX6000 (including shipping). I wouldn't do anything different. The GX7s are tanks.

You won't get any power from it (nx6000) on a generator because of no power factor correction. It sucks it's power in 80 amp gulps rather than a steady state draw.


(power draw in purple at the bottom, each tick on the vertical is 10 amps)


A generator can't rev up the rpm's fast enough to keep up with the varying draw. They are shore power only amps (and do a pretty good job if used that way).

The nx6000 is too much amp for T48's, It puts out ~97 volts, too high for these cabs.

So Qsc would be the choice
Thanks

GX7 is far more versatile than the NX6000 but on shore power the performance is fairly similar. Only on generator will you see a huge difference.

Reliability is about the same. I have a GX and two NUs in my shop right now that need to go to warranty repair. The number of failures is roughly proportional to the number installed. In GX series has a higher than usual failure rate for me (albeit in a rather small sample size).

For lightweight amps, I have Peavey IPRs in my rig and have had good luck with them. If you’re regularly running on generators, though, Iron is the only way to go. They’re Heavier and less efficient, but Extremely reliable.
