Ground Loop Isolator - Cable TV Audio Isolation Transformer,Hum Buzz TV/Noise Eliminator

Completed eliminated loud hum caused by the incoming cable coax. No signal degradation noticed.

As advertised, removed hum from audio/video system. Good deal.

The media could not be loaded. There is nothing negative to say . It is the best invesment for your equipment . I have a lot of equipment and it works flawlesly. Before the noise was very umbearableI am ordering a second one just in case I need it . It is that good . It cleaned all the RFI out of my Home Theater . Don not buy a power conditioner it is a waste of money and time . I bought a 2k one and returned it right back as it did not do anytging but occupy space .

Was experiencing a low hum on every input through my amp - loud enough to annoy and in increased with increased volume. Added this isolator to the cable box on the cable input the reattached the cable from the wall - problem solved. No hint of the hum, even at high volume.

This isolator did a great job of isolating my cable box ground once I managed to get the input side connected. When I got the isolator, the center hole on the input side was too tight and would not let the center coax wire to go in. I requested a return and ordered a second one. The second one had exactly the same issue. Once I managed to get the cable on (by using one of the two units’ output side to plug into the other one’s input) it worked fine. The quality is good and the price is reasonable. I took one star away because of all the time I had to spend to get the cable connected to it.

It did kill the hum but added signal loss that the TV picture was distorted and almost unwatchable. Tried it a few times at each end of the cable, checked the connections, etc. The TV signal is fine without the isolator. So definitely its the isolator which is adding a signal loss.

Wow, by far the best $15 I've ever spent on my audio system! For years now, I've suffered with this annoying buzzing/humming sound coming from all my speakers in my 5.1 audio system when watching TV. I've tried different HDMI cables and re-routing HDMI cables to no effect. I've also tried plugging components into different outlets to no avail.After stumbling upon this device and reading how it got rid of buzzing sounds for others, I figured I'd give it a try. I didn't have high hopes, but immediately upon connecting it to my cable box and then connecting the coaxial cable to the device, the hum/buzz vanished and now the speakers are dead silent! It turns out that the ground loop buzz is apparently occurring in the coaxial cable that comes from the cable company wall outlet and connects to my cable box. And then the buzz was being carried by my HDMI cable from the cable box to my Audio Video receiver. Oh, and also, I see no degradation in the video quality when watching TV.

The product seemed to be good quality. It did help to partially eliminate my 120hz ground loop hum from my cable box. Definitely much less audible than without it.It also keeps the cable box from improperly sending a signal to my subwoofer amplifier when the cable box is off. For some reason the cable box was waking up my sub amp out of standby mode. But with this isolator attached t9 the cable box it doesn’t happen anymore. The standby mode on my sub amp works properly now.
