My UPS(2200va IDEL made in Korea) just got burn out due to voltage fluctuation. I want to use a voltage stabilizer (that has low/hi cut out point…<<100volt/>>280v). so is it ok to use a voltage stabilizer before a UPS? Coz someone told me not to use due to usp has its own stabilizer.
thanks
Voltage Stabilizer vs UPS...
I've ordered a Furman PM-8 E SERIES II POWER CONDITIONER. It is on sale for little less than the PL model - otherwise I wouldn't have paid the extra for the meters (I might have been curious though) 
But to be honest, I have no first hand experience. A local venue uses a couple of Furmans. The sound at that place is quite good. But the Furmans are - at most - not the only reason for this.

Re: Voltage Stabilizer vs UPS...
There are all different sorts of devices out there. I suppose someone, somewhere makes a unit that both stabilizes and also provides emergency power in the event of a blackout. If all you have is a garden variety UPS that does nothing but provide battery backup in the case of a blackout, I don't see any reason why you can't plug that into a voltage regulator. I have a Furman AR1215 here which I swear by. At very least it's cheap insurance for all my gear. Digital equipment (in particular) doesn't like it when the input voltages drop too far,firubbi wrote:My UPS(2200va IDEL made in Korea) just got burn out due to voltage fluctuation.

btw - those power conditioners are nothing but expensive fuses (and convenience outlets). The only audio benefit they provide is a tiny bit of filtering in the event of dimmer noise (probably worse at your local tavern).
