    Finally, no speaker whine.... 3 years ago I updated the stock stereo and speakers in my 1995 Mazda Miata. Because it is a convertible, I wanted to make sure I had enough power and volume to even hear the words of an audio book with the top down, going 80mph on the California freeways. For 3 years I have had issues with a speaker "whine" if I had the amplifier's gain up too high (volume was always too low because of that). I made sure both the stereo and amplifier were properly grounded, but I could not fix the issue. I installed this simple filter, and now the whine is completely gone. Although this device may not work for everyone...it worked great for me! 5Made my custom PC>Mixer>Stereo situation better once I used 2 of them Got rid of my noise in my setup. I have a PC setup with a 3.5mm to RCA "Y" type cable going into a desk mounted DJ Mixer that I use for volume control. That mixer is hooked to a Kenwood rack stereo that is always on. The Kenwood feeds my Bose Accoustimass subwoofer satellite speaker system.I was having lots of static electricity issues and it was even tuning in some radio station at times. I bought one ground loop isolator and it helped. I changed it from between the PC and the mixer and between the mixer and the stereo. I finally got a second and put one on each side of the mixer. I have way less noise. I occasionally get a pop noise about once ever few hours. I get a tiny amount of noise out of the potentiometer in the mixer. I have to turn it a bit to get rid of it. I have used 'tuner cleaner' which is a spray. That helped a bit but doesn't last. Taking apart the mixer revealed a puddle of tuner cleaner so I am done with that.I am going to try and ground the mixer now. Before having these 2 isolators grounding actually made it worst. Maybe it will help now.Let me know if you have any additional suggestions. I was spraying antistatic spray on the carpet in the room and using a humidifier which helped a bit too.Also, I mounted my mixer in a formica countertop I build my computer desk out of. I should note that if I pull it out of that countertop it has way less noise. I'm thinking of wrapping it in some type of anti static plastic that motherboards come in. I have changed the Y cable several times and even upgraded my RCA cable to the stereo. 4Cheap, kills bass. Well, it gets rid of the ground loop noise, but... First of all, left and right are swapped between in and out. That I could deal with, but the claim that it has a roughly perfect response is a lie. It kills the bass under about 90-100 Hz. (Goodbye kick drum...) Not worth money. In fact, if someone offers you one as a gift you should slap them.Note: I spotted some reviewers saying it didn't remove the hum. If you are using one of these and it hasn't removed the ground noise, you must figure out what is grounded to where then make sure this item is actually in the ground loop. Also, this is not for fixing a record player's hum. For that you must have a phono pre-amp. Also worth mentioning, if this device is near the back of your receiver the crosstalk with the transformer will sound like a ground hum. Unfortunately, even if you find a good spot for it, it will still ruin the low-end of your sound. :P 1Ruins Audio This thing is highly overrated and very overpriced. It is made from cheap plastic ie... Fake Metal. It is much smaller than the picture implies and the leads are much thinner and delicate. Inside is a 49 cent choke and a 13 cent capacitor. It is rated at 12 amps. Well, maybe it could handle brief 12 amp peaks but the choke only has a 4 amp rating. Consequently, strong bass becomes choked and distorted. I measured a 5 volt drop at sound peaks! It will be joining the other plastic at the landfill. 2Worked flawlessly Worked perfect at removing the ac buzz I got when I hook my guitar amp up to my stereo system. It was pretty loud, and turning on light dimmers in the house made it worse. Completely silent now and it doesn't seem to affect audio quality at all.My complaint is that the left and right channels actually switch in the box. So the red wire on one end goes to the white on the other end. That would really mess with OCD people. I've got a mild case of it, so it bothers me enough to give it 3 stars. Who knows, maybe mine was a fluke or something. 3Just what the doctor ordered! For the last couple of years I've tried off and on to eliminate the horrible hum that came whenever I tried to connect my PC to the "line in" inputs of my stage piano so that I could pipe both the sound of the piano and any MIDI controlled VST's running on my PC into my studio monitors. I'd just about given up hope of ever getting this to work, but eventually decided to try one more time. In doing my latest research I ran across this inexpensive ground loop noise isolator and decided to give it a try.When I got it, it only took about a minute to hook it up into my existing set-up. Then I loaded up my VST instruments on my PC, set up the piano to transmit MIDI to my PC, crossed my fingers and began to play...pure musical bliss without a trace of hum. Woot! Wish I'd known two years ago what search terms to look for when scanning Amazon for a solution to this problem. 5Listening to music is probably my favorite hobby. I went through three different home built ... Listening to music is probably my favorite hobby. I went through three different home built PC's (have been building my own systems for a while now) to get rid of noise emanating from these builds i.e. Home entertainment PC based systems. This little box cleared up the noise completely. It does exactly what is was designed to do, i.e. get rid of input noise. For more details read on.I'm a PC enthusiast with audiophile taste but not their pocket. My previous system was an Amd FX-6350 CPU and a Sound Blaster X-Fi Platinum sound card for a 5.1 sound system. Two power amplifiers and 15" and 12" speakers for sub's and front and other smaller speakers for rear and centre. My FX-6350 System had no noise problems but I was dissatisfied with it's performance. I messed up my system striving to extract more performance from it. The system froze during a bios upgrade ending my MOBO's life hence the need for my new build, an FX-9590 PC. I went for an upgrade of my sound card as well.The first new system an AMD FX-9590 with a sabertooth 990fx and an upgraded Soundblaster Z sound card was working well with the exception of noise coming from the sub-woofers and to a lesser degree from the front full range speakers connected to the pyramid PA-1800X and PA-800X power amplifiers respectively. The whining static like in and out white noise morhed with a high pitched sound of a few kilohertz was unbearable especially since my new sound card was rated @ 116db S/N ratio.I tried a different power supply and video card which helped a little but the noise was still there. Bought another MOBO but the thermals of that board was too low for my new 220w tpd processor, but worked well my FX-6350. I then sold the first MOBO the sabertooth 990fx which locked up on the boot screen. I thus gave up the second MOBO which according to my research had a few successful builds with a FX9590 CPU. I sold it along with the FX-6350. I'm now down three MOBO's I have a powerful new CPU and no working system. I then purchase my final MOBO a Crosshair V formula Z and guess what the noise is back.I researched the problem on-line and tried sheilding the sound card with foil and cardboard - no significant difference. With my MOBO bios one could save various bios setting profiles, so I underclocked the machine significantly from 5.0ghz to 1.5 or 1.8 ghz. It helped but noise was still there but more tolerable but the machine's performance was significantly diminished.. Frustrated with performance I went back up in clock speed and turned off two of the eight cores, it helped but not enough. I was convinced that the problem was processor based I had no intentions of buying another MOBO. SInce Sub-woofer output is mono I used two ten band equalizers in series i.e. channel into channel and then equalizer into equalizer and attenuated everything from 300 hz and above. total attenuation 12db per channel times 4 - 48db this yielded the largest reduction in noise and I used this system for a while but in a quiet room, anyone with a keen ear could still hear the faint noise.While searching for a better solution on-line I came across a number of possible solutions and one of them took me to a device similar to this one on amazon. I reviewed the specs and especially the reviews of devices similar to this one and despite a few negative reviews after careful consideration I decided on this one.That is a decision I will not regret. My noise problem persisted for several months and could be detected in a room from a distance of twenty feet or more feet even with the volume muted on my PC. I tried a number of possible solutions which had limited to no success at all. I went through three different motherboard at a cost of a couple hundred dollars and guess what the solution was this device available right there on Amazon for less than 10 bucks.I highly recommend this product it works. I experienced no audible signal loss as some reviewers claimed but I did experience full noise loss. I think it was designed for car audio but it certainly works for home audio. Now I can put my ear to the grill of my 15's and hear no noise whatsoever with the PC soundcard volume at one hundred percent while nothing is playing. Thanks Boss audio for a great product. 5Horrible quality Before buying two of theses, I read the reviews of others. One review said that the cables were backwards on the output from the input. I did not think that was anything bad, I could just switch the cables. So I tested them on the RCA cables coming from the VCR. They were backwards inside the product on both of them. But with in a few minutes one did not work at all, and the other never did work on one side. I ingnored the bad reviews and bought them anyway, because it was a brand name that I have heard of before. It is obvious that the manufacturer put little effort in the quality of this product. 1Completely eliminated hum between computer and home sound system! I had a serious ground hum/buzz issue when I plugged my desktop computer audio output into my home stereo system. I purchased this BOSS B25N Ground Loop Isolator and placed it in line between the computer and the stereo system. The problem was solved immediately. The computer channel is now free of background noise. Note: I did not realize that this unit is designed primarily for automotive audio systems when I bought it. However, it works perfectly in my home sound system. 5Worth Every Penny! After checking all my grounds (which turned out good) and making sure my cables were routed well away from the power cord I still had this faint buzzing from the alternator and it was driving me crazy, but after installing two of these isolators for my front and rear speakers (that are powered by a 800 watt amp) the noise is GONE! They are absolutely worth the cash and they work. Just to make sure the connectors don't come loose at the female end to your RCA jacks just wrap them with electrical tape (a small piece) to make sure they stay together when installing. 5
