Last nite I set up my rig (Alembic F1X/QSC3002), I was just noodling around and tuning up at very low levels, and all of a sudden smoke started coming out of the top port of the cab. It looked like a chimney; it was thick, grey, foul smelling smoke. I powered down and waited a little while...Powered back up and SAME THING...Took my flashlight and started looking around, checking cables, connections, etc, etc... Finally after 3 or 4 on/off cycles, it stopped, but the horn quit working and the control knob would no longer turn. (I had it completely OFF) The speakers still worked and I was able to do the gig, but this morning I removed the X-over board from the back of the cab; the fuse was blown and the pot for the horn control was competely burned. I took off the cover on the pot, and it was totally charred inside and was oozing a nasty tar looking substance....Weird...Even the club manager was about to grab a fire extinguisher. Good thing it didn't start a fire...Anybody else ever have this happen? I'm gonna call Eden tomorrow. Slug
OUCH!!!! Smoke=not good. Fire=even worse. I fried a guitar amp years ago in much the same fashion. It was a combo amp and it was destroyed. I hope that is not the case for you. Turned out, for mine, to be a shorted wire that got hot, melted the insulation, then shorted the circuit board. Like a never ending chain reaction. I hope yours is not as serious.
I robbed a horn control pot out of one of my other Eden cabs and it's working fine now....It seems like the pot just gave up. Slug
Wow, I thought Eden gear was Quality. To be honest, I kind of laughed when I read the title of this thread. Well, glad its alright.
>>> This cabinet has several hundred hours of very, very hard use on it... Even with the failure of that part, I was still able to do the gig... Slug
That must have been a fun gig. I would have spent the rest of night wondering what was going to go on fire next
That happened to my Avatar cab except my horn burned out instead. It ended up like this: Bass picking up transformer noise when i sat down next to my rig with my bass + DDT Limiter off + Active Treble on Bass cranked + Bright switch in = Feedback + High frequency signals + amp clipping + smoke pouring out of the 1/4" jacks on the back. That all occurred in about a 2 second time span. It was the perfect spontanious set of circumstances for disaster we all subconciously fear.
you had the horn turned off? that means you all of the power was going to the L-pad (pot) instead of the tweeter. all of that powet gets disappated as heat, that's where the fire came from. if you going to run the cab with the tweeter off, you may want to remove it from the circuit.
Or, don't turn the tweeter attenuator all the way off, have it on low, a click or two, but all the way off is bad.
Yeah, I had a similar situation with lots of high-frequency feedback going to the horn of my Eden CX110. All that happened is that the fuse blew.
It says right in the owner's manual, "Never, under any circumstances, let the smoke out of the cabinet."
