At rehearsal, nothing different other than the latest firmware update applied today. Mine started smoking and flamed up about 1 minute in. Our other guitarist's lasted about 10 minutes. The only thing we did was the latest update about 10 minutes before we started. We play in a really nice rental studio with clean power. We both have the passive units. I don't know what to say but I'm not too assured by this. Is anyone else having an issue? I'm taking mine back in the morning. Our local shop has a "No Lemon" policy so we're covered. We're supposed to start touring in November. I can't take something with me that I can't trust.
Our Kempers both caught fire tonight

Photos, or it didn't happen!

I don't think I can rewind time to post a photo of our Kempers with smoke pouring out of them. It happened, I have no reason to BS any of you.

I'd be highly suspect of the "clean" power for the studio. You should get a UPS rated for the draw you need for all electronics equipment anywhere you're running (possibly one per band member, they're dirt cheap from best buy etc and will save your kit and properly condition the power unlike just a "conditioning power strip"). Make sure not to overtax the power system either.
Oh and also how were you plugged in to the Kemper and what were the KPA's plugged in to? If it's the kemper power amp you should make sure the ohm ratings matched on the output for correct draw, on input likewise you don't want to run too hot a signal.

We use Furman AR1215 line regulators. Not the cheap power racks. The studio is a multi million dollar facility owned by a grammy nominated producer... Everything is on the up and up. We use the passive units, not the powered ones. They plug direct into an Allen and Heath WZ3 12M IEM monitor board. All of our gear is top notch and well cared for. Believe me this isn't our other gear or the power that's causing it. Right before rehearsal, the only thing that was different was I brought my memory stick so we could update the firmware. That's the ONLY difference between today and the last month of almost daily rehearsals. We're all very familiar with our gear and it has worked fine until tonight. The only difference being the firmware update that was recently made available.

pm'ed.

Wow, that is a exeptional story!
We will investigate your units to see what happened.I can actually assure that a severe hardware failure cannot be caused by software, as all power related modules are not driven by firmware. It is also not possible that other components draw too much current caused by firmware. Our power supply is taylored to supply the maximum current to every component, which is a common design rule.
The new firmware is installed on most of our company Profilers, as well as on many user Profilers, and run well.
The fact that two units broke nearly at the same time, and that they seemed to play well prior to failiure leads me to the assumption, that an over-voltage has caused the defect, even when the power line was secured.
We have got in contact with you already.

Wow, what the fuck! Shit happens... must've been some voltage peak or something like that?
I'm very sure that it has nothing to do with firmware though! -
I own an AR-1215 and find it difficult to let pass any overvoltage or surges, I'd suspect the connection to the Allen & Heath monitoring board. Maybe a shorted ground connection somewhere in there?
-
Wow , sad story ! Did any other hardware in the studio suffer from the same symptoms ?
-
I would be more inclined to believe it was a KPA issue if only one of the units smoked. The fact that two smoked at the same session increases the likelihood that there was a power issue in the room.
-
Power conditioners, Grammys or not ... two anythings setting on fire in the same room has to be the voltage being fed, surely.
-
WOW cant believe that happened scary
-
What chord / song were you playing when the KPAs went down in flames ??? I want to know this devilish trick !!!
... sorry but I couldn't resist the spinal tap joke ...

Probably Blaze of Glory by Bon Jovi

i"ve heard of guitarists being "on fire"but this is a bit extreme.

You didn't actually try to toast bread in it, did you?

The toasting is usually fine, its when you try and fish out the toast with a fork that you really run into problems.
Joking aside, this really sucks and I am glad you are covered and hope you can rule this fault to some other equipment and not lose faith in the Kemper.
