I have a directv ground loop hum in my home entertainment set-up. Will this isolator eliminate both cable AND satellite speaker hum?

I'm not an expert on this issue, but this product solved my problem which is with a cable provider, not satellite cable. The specs as I recall specifically indicate not for use with satellite, but then for the meager cost of this item I would try it since it sounds like you are attempting to eliminate a hum in both. It could be that the cable is causing the hum. In my case the hum existed any time the cable was connected to the sound system even if the cable box was turned off and I was playing sound from another source such as our Blue ray player.

Try this: disconnect the coax from your cable box. If the Direct TV speaker hum goes away, this isolator should solve your problem.

Lucy,I found the source of my hum. I have Direct TV HD. I found that going into the menu settings/Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver!Larry

Are you sure it isn't the subwoofer? It stays on all the time even when the system is turned off and produces a low level hum, constantly. That seems to be the norm for all the subs and the Onkyo receivers. I was surprised to walk into my media room and hear the hum coming from the sub and the system was turned off. Sub is always in stand by. Just a thought.

Mine is crystal clear.. I had a low freq amplifier type "hum" in my system but that was fixed by using RG58 to carry audio to my subs.. (was picking up interference from A/C power systems in room)

i doubt it. from what i know having your equipment plugged into different circuits would only make the hum worse. in any case if your equipment hums it is probably not worth spending this much money to fix the problem. good equipment doesn't hum no matter where you plug it in. i suggest getting equipment that uses balanced ( XLR ) or digital ( Optical / Coaxial / XLR ) interconnects. Regular consumer unbalanced analog technology is inherently inferior and was never designed for high performance.

My speakers and headset responds the same as yours by not muting with the TV. It actually even keeps working (broadcasting the station) when the TV is off. I have the unit connected directly to the "Cable Box" and not the TV Unit.

You know I had to go and check! However, I have an 828LM and no hum whatsoever. Have you unplugged (the replugged) the unit and tested it away from other equipment for this humming noise?

Nothing I tried that and got nothing. .i even bought a y splitter to run 2 sets of speakers and got this loud humming sound!!

What you are referring to is most likely a phenomenon called "ground loop" or ground loop noise. This occurs when two or more items use the same ground arriving through different paths or it may also be EMI (electro-magnetic interference) from the various wirings around it. The easiest solution to get rid of it? A ground loop isolator works wonders and in this particular case there are ones available that require no special modification or installation, they install basically "in line" with the aux cable! I found one on Crutchfield and also on SonicElectronix (eBay as well) for less than $20, although I have yet to find this particular style here on Amazon. http://www.sonicelectronix.com/item_8987_PAC+SNI-1-3.5.html

Probably a connection issue with one of the components hooked to the TV (mine happened to be a Sony DVD player...) removed that and the hum went away. Gave me an excuse to get a progressive scan DVD player... hooked it up and still no noise. It took me a bit to narrow it down, since I've got so many console systems. ;)

Yes! I get this annoying hum that only goes (mostly) away if the bass control is all the way down. The volume control has no effect and it doesn't matter if the satellite speakers are plugged in or not. I wanted to put this next to my bed but the hum is intolerable. I plan to return it. I don't know if I should try getting a replacement or if I should give up on this model entirely.I got a replacement and it is worse. It buzzes even with the power off. With the power on I can hear the hum across the (quiet) room. When it is close enough to reach the control from my bed, the hum drives me crazy. Yes!

Goes from single in or out to L R Chanel's I bought to split sub Signal but a hum occurred not balanced

I get the same thing from a Vizio. You could probably get an in-line noise filter to fix that problem but the hum mine isn't loud enough to bother me so I haven't done much.

Drear Lorain, This will eliminate ground loop problems with your cable modem but are your modem's ups and downs caused by a ground loop? Not very likely. Ground loop noise is at low frequencies - mostly 60 Hertz and might reach as high as 1 MHz. Cable modems operate above 5 MHz thus what you are experiencing is most likely interference, such as noise coming from other cable modems that share your line. Another cause of ups and downs is a faulty connection or faulty cable amplifier and the best solution is to call the cable company to test the line. If you still want to try this isolator it won't hurt and there's a small chance it will work for you. Eli

You have a ground loop somewhere. These can be hard to find and fix. I would do some reading on it. Musicians are often very familiar with this problem. Often times it's as simple as making sure that the two devices sharing the circuit (for example, in an audio circuit like this, the computer generating the audio signal and the speakers outputting it) are on the same AC outlet -- often times plugging into different AC outlets can introduce a ground loop. I've had some luck with ground loop isolators and filters. Amazon sells a number of these. You'd want one that's targeted toward your specific cable type. I've also had some success upgrading my audio cables. In one particularly annoying case I finally isolated the problem to a specific AC/DC adapter. When I replaced that with an equivalent, the problem went away. Diagnosis can be tedious. For that last one, I repeatedly unplugged everything then started connecting things one at a time until I found the pattern where the AC/DC adapter was the offender. I had another one that turned out to be a coax cable TV cable -- I have a TV as one of my sources on this device. A coax ground isolator at the cable source took the problem away immediately (I was surprised at how easy that one was). In addition to the specific isolators/filters you plug cords into, you can also get small suppression devices (RF suppression) that snap on the existing cords. I haven't had much luck with those for my specific problems. When you buy a cable with those cylindrical bulges at the ends, that's often the same sort of thing built into the cord.

it solved my humming problem when i used 2 or more components plugged into my receiver. but when i got a more powerful amp i didnt need it. i would try it...you can always return it.

Remember, this is to stop grounding faults so when you plug something like your computer sound card into your TV, you don't get that hum. You probably don't need it on most of your tv's.
