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

Product Information

You'll find multiple promotions on isolator happening daily, so you won't miss out on getting the savings. As the Samsung tablet is battery powered, im 95% confident you won’t hear noise with it (unless it’s plugged into a charger. One reason is that cheaper models often use low-quality audio isolation transformer parts with poor performance across the 20 to 20kHz audio range.

A loop has formed, which allows these noise signals to be picked up and carried by the signal conductor and/or the ground shield conductor of one or more cables. For rather complicated reasons, current can leak into the shielding of USB cables which affects the signal. This in-line dual isolation transformer eliminates hum and other noise caused by ground loops, while providing protection to the portable device.The best way to avoid any ground-loop issues is to hook all of your audio equipment up to the same power group.

The next test I am going to conduct is using an audio source, like my Samsung tablet, and connect it to my amp and make sure that no other devices are connected to the outlets on that circuit and listen for any noise. The most common manifestations are a loud buzz or hum coming through the speakers, or scrolling bands on a TV screen.I have an Android head unit connected to 4 door speakers (coaxial) via factory fitted harness, all coupler to coupler fitting. Most are easy to use by plugging the RCA connectors inline with RCA cables and then to the amplifier.

When you power inter-connected equipment from different AC outlets, you’re apt to create a ground loop: The ground will travel through the shielding of the signal cables.

Internal audio solutions, especially those that reside on a computer’s motherboard, are susceptible to all sorts of line noise and electromagnetic interference that can’t be eliminated. PLUG AND PLAY】 Plugged this ground loop isolator directly into the cars/speakers AUX port, then the aux cable into the audio source. Tripplite sent me one of these as well: the excellent 1000-watt IS1000HG (Hospital Grade) with four outlets.
