Will this solve AC hum in home components?

This is for eliminating ground loop hum. This is very common in cars where just about everything has the ground (negative side of battery) connected to the chassis of the car. Having more than 1 ground path can create thishum. Using Unsheilded cables can also create. So I think you have 2 options. If you are getting the hum in the car, than this should work fine. If you have the issue in the home you probably have a shielding issue and you could try this but your mileage may vary.

Unfortunately, you can't know until you use it. It did not work between my mixing board and computer, but it may just be a compatibility issue.

I purchased this for a classroom that had a 3.5mm audio wall plate to speaker that was humming. It did not resolve that issue. For home components I would get a quality a/c line filter, or even try replacing the a/c outlet with a higher quality one. See PS Audio.

I bought this for reducing the AC hum for a FM transmitter, but it doesn't work.

There are cheaper ones that can also get the job done on Ebay. One thing going I haven't tried is using two at a time.

Yes. That is exactly what I purchased this for. That annoying Humm is now gone. I was getting that Humm from my home theater sound. It worked perfectly. I'm a very happy customer.

There is a slight hum, intermittently, when it kicks on to maintain temperature. Not much, however.

it has a loud hum . I grounded the units directly to the Case of the Computer. It reduced the hum significantly. I replaced both units just last week because these are pretty much junk in my opinion.

Not sure on the moaning, will cerainly allow a steady current flow to your A/C unit making starting easier.

No noise or hum - I forget it's even there unless it's doing it's self test (about 5 seconds) then it's quiet again. South Florida.. we have lots of power interruptions and it's been a blessing.. I know it has saved my computer time and again.

I have sold several of these without any issues. Check your ground at the panel. I think neutral and ground need to be bonded in your panel if it is hard wired to panel. If you mounted an outlet to the inverter, try connecting the ground and neutral together and the use a ground rod to earth. I cant think of anything else that would cause it. Sometimes fans will hum slightly, that is from the square sine wave but I havent heard of buzzing in stereo yet.

We put this in a small office and it has been quieter than most air conditioners we have had. This air conditioner has a slight hum as most would expect from an air conditioner. As far as in your bedroom, this might be as quiet as it gets for you.

I would probably try their control before a generic rheostat.From what I've read they can induce hum, and possibly shorten the life of the fan. That said, I use a variac auto-transformer for my fan. I already had the variac, which I use for electronic repair. It works very well, infinitely adjustable, and is very quiet!This fan seems to be very good quality, and I am quite pleased with it.

The contactor is inexpensive, so there is a noticeable coil hum/buzz. But does that with everything. Should work just fine with fluorescent fixtures.

It worked for me. It kept noise coming in on cable connection from making annoying hum when I had cable box connected to audio car in computer. I think it would be worth a try.

Hard to give answer , depends on breaker box set up. AC comes into house as 220 volts then it is split into two 110 volt circuits with breakers on each circuit in the breaker box. Any outlet on the 110 volt circuit will definitely have good results. If the carriage house is on the other 110 volt circuit you may get a hum during reception , changing outlets in the main house or in the carriage house may cure the hum. We found good results with the intercom when plugged into SOLAR 110 volt , our power failure backup, so 60 cycle AC is not critical to the unit operation

I guess it is all relative .. Mine does make a hum... If our room was perfectly quite it would be annoying , but we have a central air fan , window ac , table fan going so it gets drowned out

In most cases it's your cables. Depending on whether you are using the high impedance or low impedance outputs check the cables. Also try separating the place where you have the board and amp plugged in. Try putting them in them in separate wall sockets at two different points in the room. It may just be a 60 hz ground loop hum.

It produces a low hum. It may not be enough noise if you are in a fairly noisy location, though.

The reason you are hearing the hum is because your transformer plates are slightly loose. The metal plates in the core are laminated and can become separated, you may be able to reduce or eliminate the hum by painting a varnish or shelac onto the core and letting it "soak in". I would suggest several thin coats to do the job. The metal core itself can be loose and vibrate as a whole too so you may need to seal that up the plastic bobbin that the copper windings are wound on. Otherwise if all else fails this unit is quiet, at least the one I got is. You may also try insulating between the transformer and the joist if yours is mountable that way. Hope that helps.

I don't know. All I can tell you is that I have a tv, computer, two stereos and dvd player plugged in. If I connect any one of the to another or turn all on at once I get no hum or static. The volume is a little reduced with each button pushed down but no other issues. It shouldn't matter but maybe a shielded cable? I used to have an old computer that produced radio frequency interference. It made static on the older tube type television if it was close to it when I connected cheap audio cable to it.. just throwing that out. Good luck.

Also, if possible only use equipment with a grounded 3 prong plug. Without the third ground connector on the power cord the equipment can't be properly grounded and so ground loop hum will be harder to avoid ...
