Damaged?

Long time lurker, First time poster. I just purchased a Genz Shuttle 6.0 12" combo that Im loving. Plenty of thump to go around. I got a little carried away this weekend playing through a peavy 2x10 cab along with the genz 12. I started smelling the distinctive smell of electronics smoke. I powered off and waited a few moments and turned everything back on and everything worked fine. I know the peavy speakers are rated at around 250 watts, and I was running 4ohms at 600 watts. My question is, What was being damaged, the amp or the speakers?

The amp is the source of the magic smoke. PM one of the Genz guys here, Agedhorse or Hasbeen, to figure out what to inspect.

Probably the amp. I'd open it up and check for any burned areas at least.

There is nothing in the amp that is likely to smoke, especially with the amp continuing to operate. It is protected against all thermal faults, and will simply go into protect if that were to happen.

It's certainly possible that you were overpowering your speakers and the voicecoils got hot enough to burn the adhesives used. It is also possible that (not knowing the specifics of the crossover used in your cabinet) that the crossover may have overheated as well, again due to excessive power.

Do not open up the amp and try to service anything yourself. There is nothing user serviceable and there are both dangerous and potentially fatal voltages present on the amplifier module.

Thanks agedhorse. I never saw any smoke, but I could smell the hot electrical smell. The amp never cut out. But I did have both volumes and the gain maxed out. But only for maybe 10 seconds max.

Well, you might have discovered the limits of your speaker with 600 watts into a 250 watt speaker cabinet. Maybe you are lucky and your speaker just charred a little.

Headroom is not headroom if you actually use it.

Hot Voicecoil former, and can smell pretty bad. Like Burning PCB (Printed Circuit Board).

What happened? Was that on purpose?

If the Peavey was a 210TX, TVF or variant...it was 4 ohms which, in combination with the Genz 12, might have been below the Shuttle's 'happy zone'.

If this was the case, the Shuttle would simply shut down. I'm 99% sure it's the speakers in this instance but this guess may not hold true for all amps of course.
