First it helps to define exactly what a ground loop is and how it may affect our home theater system. Rated 5 out of 5 by Anonymous from Removes hum I use this ground loop isolator to remove the hum when connecting a laptop's headphone output to my stereo amplifier. Rated 5 out of 5 by Hi-Fi Lover from Top shelf performance, budget price!! Torus Power products provide a smarter, simpler, and more effective technology to clean up dirty mains power. The outdoor grounding is to make sure ground differences across the cable plant don't fry your equipment, electrocute you, or burn your house down. The red or white, should not have continuity to any of the remaining three wires. If you have a buffer available, you can keep the secondary output voltage from dropping off so quickly by driving the primary harder.
The connetion is easy: connect primary side of the transformer to one audio connector and secondary to other. . First, you have to consider what is driving the transformer and what the transformer in turn drives. Has anyone built one of these interface cables, and you tell me if this is right, or give me any other general tips? Rated 4 out of 5 by Tony the Tinkerman from Sturdy box, wimpy transformers I got this device to reduce the annoying computer whine I experienced when I connected my desktop computer to my earth-grounded stereo setup. For around 80% of ground loop problems this is the cure. Truly adequate performance would require quite a bit more metal in the transformer cores. In an unbalanced interface video and consumer audio , this ground voltage difference directly adds to the signal.
If it does then you might be able to solve this with a simple ground-lifted signal cable between the two. Anyone able to shed some light on this? This can be measured only on your lowest scale. If the cable is not very long not many meters , in practice it does not matter to which end of the cable this transformer isolation circuit is connected. Often you want to adjust the voltage anyway when you're debugging power circuits where you want isolation. In that case, put the variac before the isolation transformer instead of after it.
Good 1:1 isolation transformers do not reduce volume well. You are assuming a narrow usage for isolation. For an unbalanced interface, the transformer effectively stops any current flow in the cable caused by ground voltage differences, which stops the noise. No bad on you though. Several weeks ago I was pulling my hair out after I installed a new component into Reference System 3 for review.
Now that we've got the transformer identified. If some of the signals in your audio system will get this kind of phase shift and some other will not, you will face all kinds of sound quality prolems. Well I installed the transformer today right before my first splitter and the ground loop is gone. At Jensen, we know that phase response is just as, or perhaps even more, important. There will be plenty of other things around at the normal ground potential, so the chassis of the transformer isn't going to make anything worse.
Problem is, everyone one wants to borrow this. Put hot in, hot comes out. In an evening you can build an output transformer to drive a Fender Deluxe guitar amplifier using 2 6V6 output tubes in a push-pull circuit. By the way, beware of inrush currents on a 500 W isolation transformer. But of course it caused horrible reception on some stations and degraded the picture quality overall. I wrote off RadioShack about 3-4 years ago now.
I thought that it was in the same league as the Dayton which after reading some reviews would have screwed up my digital cable and cable modem. As an alternative, use 600:600 ohm isolation transformers similar to those used in telecommunication equipment. The cable ends are both stereo 3. A guitar pickup has an internal impedance that runs up to about, very roughly, 100K at the top end because of the inductive nature of the pickups. Most audio transformers are integrated into an audio system such as a high fidelity or power amplifier. If that is the case, a groundloop isolator will not be your solution.
Ed itorial Note on Ground Loops When two or more devices are connected to a common ground through different paths, ground path noise, or a ground loop can occur. I hope that you are wrong and it's just the cable companies ground causing the problem but I guess I won't know until I get the transfromer on Friday and install it. Your assumption to connect the red and white wires to the speaker output of your sound card is correct - go for it. Connect it up and have fun. And as there can be only one reason for that occurrence given that both tools are known to be operating well individually, it will be instantly known that both tools need urgent repair. If you for some reason connect the wires in one side of the transformer in the wring way, your transformer will cause a 180 degree phase shift to your audio signal.
AliExpress takes pride in making sure that you always have an informed choice when you buy from one of hundreds of stores and sellers on our platform. I once blew a 30 A breaker with such a transformer, even though I had switched it on a number of times previously on the same circuit. And that kills your high end. Does the hum go away? This addition will help minimize distortion and reduce noise—and then you'll have an audio signal with good clarity and definition. Unfortunately this was on a weekend and the breaker was in a different locked room. The clean power supplied to your system thanks to the Torus Power isolation transformer will not only allow it to run cooler, last longer, and consume less energy, but also will allow audio video systems to achieve their optimal resolution and dimensionality — with blacker blacks and thundering bass — brought together by Torus Power to enhance the listening and viewing experience.
Put cold in cold comes out. Get inspired by articulate audio and dazzling video. The audio transformer is Radio Shack 279-1380. Thank you very much for your input concerning frequency optimization, I am now only looking at Audio transformers. So - maybe it would work; it depends on the transformer, the buffer, and how hot things get.
