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

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.

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.

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.

I've used this power conditioner for over 10 years on my bass rig and after 100's of shows it's still working great. Its seen multitudes of stage floors and has some battle scars to prove it, but I'm never concerned that it's not going to do its job. Having a good power conditioner can be crucial in a venue with "dirty" power and sometimes it's an easy fix for unwanted noise issues, nowadays I always use it just in case.Every now and then I run into the problem where I need more than two outlets and I guess I could get a different power conditioner to remedy that issue, but the size is very convenient and for the majority of situations this one fits the bill.

This unit demonstrates firsthand why professional musicians love Furman products. Eliminated Humm I was experiencing, while at the same time giving me confidence that my HiGi system is both optimized to eliminate noise and protecting my expensive equipment.
