Boss Audio Ground Loop Isolator and Noise Filter

works very well in eliminating all alternator whine and interference noise for my subwoofer in my car

This was required to stop interference on a car head unit I bought, simple to install and did the job.

I brought two of these, this one and one from another manufacturer just incase one didn't work or perform well enough even though they are suppose to do the same thing and I expected the Boss to be okay as it is a well known manufacturer to work. The humming noise was still there and it emitted other high pitched noises that wern't there before or without it. I am not sure if it was fault but as stereo it does have two transformers inside and both didn't work and emitted noise itself or maybe it is from a faulty batch. Notice, the cheap metal plated plastic. Why couldn't they just not bother and put the expense back in the functionality where it matters. Very disappointed

Very light and plastic. Didn't remove my ground loop hum

Was having problems with buzzing from my speakers, fairly quiet while playing music but louder while playing games. This ground lift got rid of the buzz completely.

To my surprise this thing worked and worked well.

Eliminated weird noises that were occurring while gaming/high load on PC (that sounds like a motorbike/car engine)

This was not fit for purpose. It increased the humming noise almost damaged my subs.

El producto es el mejor de este tipo en Amazon, el punto es que quita totalmente el ruido pero también los bajos o grabes del sonido, solo se escuchan los agudos !!! eso a mi no me funciona !!! sobre todo en equipos caros y de vanguardia en sonido de casa Marantz !!! lo tuve que regresar !!! una lastima !!!

Ok

Good

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.

This is a fantastic product at an even better price. My projector is a fair distance from my tech booth. Since the projector and audio equipment are plugged into different circuits, the ground potential is not equal. When I use my laptop (connected to the projector) to record audio from the sound system, a loud hum is present. It's not practical to plug the projector and sound system in to the same circuit, and I couldn't find a VGA isolator, so I bought this. It works perfectly, eliminating the hum entirely, and not even changing the level of the audio.
