I am having a problem here. I am running a denon3800 dvd player, a krell home theater standard 2 preamp, a krell 2 channel amp, and a krell 3 channel amp. They are all being powered by a monster hts7000 which is plugged into a Monster avs2000 power regulator. Nothing else is plugged into the wall outlet or any of the other banks of the avs2000. I have swapped 3 avs2000's out so far. They keep shutting down and an error tone goes off. The first one blew up after 2 hours, the second blew up after 15 seconds and the third lasted the 3 hours I was there and eventually blew up in the middle of my clients new years eve party. The power outlet is a 110v 20a circuit. I believe the 2 martin logan descent subs are on the same circuit but the electrician denies it even though the circuit breaker panel is labeled with the subs and the equipment on the same breaker. Any thoughts on what is causing this or what can fix it? My ideas are to plug the amps into the other outlets in the 4plex outlet and leave everything else as is. I do not know why this is happeneing. The AVS2000 manual says it is capable of driving the amount of power I am driving. Any ideas or input would be greatly appreciated. Thanks

You haven't specifieed what "blowing up" means.

My first guess, solely from your description, would be a speaker-wiring problem, most likely at a speaker's terminal, maybe in-wall (drywall screw puncture, for instance).

Otherwise, there is a power-supply problem. I'd try plugging the amp directly into the wall. Power conditioners can fail, too.

By blowing up I mean It just stops working, no power passes. When unplugged and plugged back in it just starts beeping it's error tone. I plugged the units into other outlets that are on different electrical circuits and it continues to beep it's error tone. The circuit braeker on the back was never tripped, it just stops working which is why I am confused. Three times, same problem. Tomorrow I am going to just plug the amps directly into the wall. I will also have an electrician out there tomorrow to check the outlet/circuit and make sure nothing is wrong there causing problems. I though about the screw through a wire being that the drywallers already cut 4 of our wires that we had to fix, but in my experience that only causes the amps to turn off and go into prtection mode when a spark crosses the wire. The speaker wire connections on the speakers and amps are all spades. At this point I don't think it's just a faulty power line conditioner due to the fact that we have had 3 in a row. My thoughts are that the circuit just may not be able to provide the power necessary to drive this system which would damage the capicitors inside the power regulator. When we plugged the power conditioner into the wall without the AVS200 Power Regulator it worked fine for a week until we could swap The stuff out. I am boggled and under a lot of pressure to make this work. Any other thoughts would be greatly appreciated, thanks for your help Larry.

I'm not sure what the AVS2000 manual states, but I have experienced the unit shutting off using a single large high end amplifier, driving a medium to difficult load. The process that it uses to regulate voltage is effective, but not efficient (or particularily fast). The current capability of the circuit post AVS2000 is greatly reduced.

I'm assuming that the Krell amps are both in the KAV series, and not FPB. Larry may be onto something in that if the load that the amplifier is driving is unusually low, the amplifier(s) may be swinging alot of power... Although not the most power hungry amps out there, the Krell KAVs might just be drawing too much power at normal conditions. In fact, I would assume this to be true as soon as I hear the setup.

If the budget is not a problem, I would recommend adding a second power conditioner dedicated to the amplifiers and only power the source component(s) and processor into the conditioner plugged into the AVS2000.

Tsvisser, thank you for your reply, i appreciate it. The amps are the kav series 2 channel and 3 channel amps and they do require a lot of power. I was told that the AVS2000 would handle it, but then again, i have been told a lot of things that are untrue, I will definately try using separate power conditioners assuming the client wants to invest more money, if not I will just have to go with separate outlets, Thanks again.
