BESIGN Ground Loop Noise Isolator for Car Audio/Home Stereo System with 3.5mm Audio Cable

Product Information

You will need an additional aerial cable fitted with male coax plugs to connect to the isolator and your device. If you’ve traced the problem to the TV signal wire that’s attached to a cable modem or similar (disconnect it and see if the problem goes away) replace that piece of equipment—there’s something wrong with it. You can get them cheaper, but the cheap ones add distortion artifacts, especially at lower frequencies as the core saturates easily. If this is the case, my first thought is to earth the metal casing of the Arcam to known earth point, such as the earth pin of a mains plug (if you’re in the UK this is dead easy) .

Car audio systems often have “alternator whine”, a high-pitched noise sound that varies with an engine’s speed while running. Ground loop noise and hum also affect video systems, although in that case, the noise often appears as distortion in the video signal.

Some mention that it works perfectly with no noticeable degradation in sound quality, while others say that the hum was actually louder than before, the buzzing was still there from car speakers, and the crackling was still present on their Rokit KRK 5's. Car models: The years stated refer to the model's years of manufacture, please check the item description for information about any changes there may be within these productions years.

This requires the electrical power to go through a conversion to DC (direct current) and then back to AC, which will remove all the noise.One reason is that cheaper models often use low-quality audio isolation transformer parts with poor performance across the 20 to 20kHz audio range. Plugged this audio noise filter up and it instantly took the buzz/hum/static out of your car audio system/radio/home stereo/speakers. No external power supply, this noise isolator can achieve a clear speech/music by eliminating the current noise in some car speakers / home stereo systems. I also had a different amp in place at one point in this system, and I did not have any noise like I do with the Carver.

If you are a long time veteran, feel free to use this as a form to discuss with other like minded enthusiasts.I suspect - though I could be doing some reviewers a disservice - that their main concern will be more whether it works or not than the degree of signal degradation. I have used optocoupler and dc-dc isolators before, but I'm not sure how I should connect them in this context.
