Furman AC-215A Compact Power Conditioner with Auto-Resetting Voltage Protection - Black

Unconventional use of this power conditioner - worked perfectly! I recently changed all the bulbs in our home to GE Reveal LEDs. The LEDs looked great (special filter that reduces yellow and highlights whites) - but when our Samsung washing machine agitated the laundry - the LEDs would pulse and flicker. After reading multiple forums - this was most likely caused by the inverter motor of the washing machine spitting out high frequency noise back into the AC line OR a loose utility neutral wire. I tried numerous different products to remedy the flicker - none of those products worked. I was pretty close to filing a warranty claim for the bulbs and replacing all of them with a different brand - but found an obscure forum where someone purchased this device and plugged it into the washing machine - which ultimately solved the flicker. I figured I would give it a try - and to my surprise - it worked perfectly - no flicker! Not sure how it works - but this seems like a very high quality device that does what other power conditioners cannot. Highly recommended.

I bought this because I was having noise issues in my Fender tube amplifier (68 Custom Pro Reverb, but any amp would have similar issues). I figured out that the noise was in the electrical wiring for my house because when my lights were turned on, the buzzing would happen. I do have a dimmer switch that was probably making things worse. After using this power conditioner, the noise from the electrical wiring / lights was eliminated. I still have a very slight string ground issue / 60 cycle hum in single coil pickups, but the noise from my Electric wiring appears to be completely gone.

This device solved a major noise issue I was having with my Carvin NS1 electric nylon string guitar with Roland synth functionality. Practicing for a wedding gig 4 years ago, the Carvin through amp started to hum, and then crackle followed by a significant drop in volume. This occurred whether or not I had the synth hooked up. Also note that the noises were not the property of the amplifiers - when I unplugged the guitar, the noises were gone. I moved my operation to another room - the problem persisted in some but not so bad in others. I changed amplifiers - the problem persisted. Carvin guitars were bought by Kiesel and I was getting no tech response from the new company. I couldn't use the unreliable guitar for that gig and put it away. The Carvin electronics were apparently hyper-sensitive to something in the AC - none of my other electrics have had such serious noise issues and I played the gig just fine with a Chet Atkins Gibson Nylon String but had to forego the synth functionality I intended to use. I recently took the Carvin out again to find the problems didn't go away - even with a recent move to another state. I had a tech very familiar with the guitar have a go. He did control cavity work that reduced the hum and even eliminated it for some amplifiers BUT the crackles and unexpected volume drops persisted. I just about resigned to the idea that I would need to lose the guitar and purchase a Godin electric nylon if I wanted the Roland synth functionality the Carvin had. Recalling a friend who swore by power line conditioners - I thought it was worth a try. Furman was a familiar name and seeing the good review of this one from another guitarist having noise issues - I pulled the trigger. I am so glad I did. The Furman AC-215A saved me serious bux (i.e. the cost of a new guitar). My Carvin NS1 sound with amp plugged into the Furman is completely free of the hum, crackles, and volume drop issues. I just sounds great - I am extremely pleased!!

This device is offers a simple and effective design that eliminated all of the potentially damaging hum coming through my speakers. There still exists an almost imperceptible noise floor, but it is only audible at significantly high volume levels.The sound quality of my system has also improved, with greater clarity and tonal quality, and a much better blend between low and mid frequencies. I used to think power conditioners were snake oil until now. I’m finally a believer.
