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

in the studio there's a number of pieces of ac-plugged audio gear and ac-plugged monitors. We had a huge problem where: if someone in the building turned a light or appliance on or off, it would often cause one or more monitors to flicker, perhaps cycle, and you would get audio pops in amps, speakers, eq, dacs etc. and there was often hum all over the place. Unfortunately, with ground or power or ac noise or ground loop problems, unfortunately there are a NUMBER of different issues that can cause your flickering monitors or popping audio or humm. For this reason there's a huge amount of confusion on the issue and, it's a crap shoot whether any "particular" solution will actually solve your particular problem. Fortunately for us, this furman (215A model) did ABSOLUTELY, TOTALLY fix all the problems we were having. It now makes no difference if, in the rest of the house, light switches are thrown, vacuums turn on and off, etc etc. The build is rock solid, and now that I've used one, I would pay 2x as much if they put the price up - it's basically "must have" kit at a very fair price for the build quality. I literally love turning on the big solid switch every morning to power everything up! Furman should be proud, great piece of kit. Take all your crap $8 "surge protectors" and throw them in the bin at last ! Safety alert - as everyone should know YOU NEVER chain proper surge protectors, you'll start a fire. Thus when you plug in a power strip IT MUST BE a completely "vanilla" power strip that >>DOES NOT<< have surge protection. It's actually getting harder to buy "real" "vanilla" power strips with NO surge protection. You'll notice in the pic we went to home depot and bought a proper "builder's" power strip which is built like a battleship, it's fantastic, only about 30 bucks which is amazing. (So just TBC the "builder's" power strip indeed has no surge protection, it's just a "real" power strip, perfect.) Would never be without a power conditioner now, this is the only one I've owned but it's golden. Not ONE pop or flicker since.

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!!

I have only had this for a few days now but I can say it 100% fixed the issue I was having. I live in an older house , 1940's, that has had many wiring configurations, changed from fuses to circuit breakers, panels added room additions etc. etc. It would be nearly impossible to correct all the different neutral / ground issues. . The problem I was having has been going on for years, buzzing thru my guitar amps. Not 60cycle but the buzz you get that goes away when you touch the guitar strings. All guitars & amps do this to one degree or another. This was extreme & to the point of being very annoying. Its an issue with AC being on the ground. It would sometimes be worse than other times & for some reason when it rained & at night it was worse. Anyway I bought the 215 because I saw some internal pictures & the inside actually had a few components in there, circuit board , capacitors , transformers. So I knew that was more than just a surge protector power / power strip. I really wasnt sure if this would help and was really doubtful that it would work. To my surprise this corrected all my problems that I have been putting up with for years. This unit actually Filters the power, cleans it up and my amps & guitars are more quiet than they have ever been. I will definitely be buying one or two more of these. My only real complaint would be that it only has 2 outlets but im sure there are other more expensive Furman units that have more outlets.

This is a good little compact power conditioner and just what I needed for a small live sound mixer board and speakers. It gave me piece of mind to know my sound equipment was protected from Spikes and AC line noise. I've used Furman products for many years. They're well built and last a long time. My only take back here is I wished they would have made this a 15A load rating rather than a 10A. I highly recommend.

This replaces the cheap surge protection I had on the big TV and speakers. I used cube-taps to get TV, speaker, woofer, and disc player all plugged into this little box. Brick-powered Roku, Echo, etc plug into a cheap power strip plugged into the wall. I don't think a surge can get to the expensive stuff thru these bricks. Got this mostly based on the brand name. I know enough electronics to appreciate a job done right. The manufacturer's claims make sense to me, but I do NOT have the test equipment needed verify this thing actually works. So, gotta trust the brand and what the manufacturer says. Cheap surge protection contains a zener or MOV connected pin-to-pin on the power to be protected. The MOV normally draws no current, but conducts large current when the voltage is abnormally high. That current opens the fuse. So, including a fuse and MOV in a power strip makes it a surge protector (just two cheap parts). Next level up on protection is filtering to stop fast transients on the powerline. The filtering gives other protections in the box a few extra milliseconds to work, so the box can be built to protect itself, and can be trusted to keep working. A side benefit of filtering is reduced noise on the output power. This stuff is not small, not cheap. Furman AC-215A has this. Next level up beyond filtering is regulated AC power. The AC input voltage may vary but the conditioned output stays constant. Easiest way to do this is AC-to-DC to storage (battery or capacitor), then DC-to-AC. Uninterruptible power supply for computer also does regulation, but these don't filter their own DC-to-AC conversion noise as well as a power conditioner. Of course, someone could copy the price and product description of an expensive product and claim their box of cheap parts is worth it. Gotta trust others that say you get what you pay for with the Furman brand. I must admit this purchase is based on faith. However, the warranty for AC-215A does NOT inspire. (minus one star for that)

Great product! I was really unhappy with the way my amp was sounding, I was getting a lot of buzzing from no matter what I did. I looked into the possible causes and was met by a huge lost of potential fixes. First thing I did was buy this and a new sturdy 6ft cable to plug into my amp and clean up the power coming from my outlet. It worked like a charm and the second I turned the amp on... all I heard was quiet. Very nice! The buzzing was one thing that was really stopping me from enjoying my electric guitars and now that it is gone I think I will be playing them much more.

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.

Terrific quality. This is protecting a mini-HiFi system. No pops, no hums, just clean sound through the speakers. It's compact and comes with the hardware to mount it, although I didn't do that. It would have been nice to have one more outlet for the price, but that of course would have made it bigger. The design is clean.
