Whatever the type of noise you’re hearing—and whatever the cause—we’ll help you identify it–and then show you how to get rid of it. You could also use with a Bluetooth Receiver/Bluetooth Hands-free Car Kit in your Car Audio System/Home Stereo. The reason is because your system is grounded in two ways; through your interconnect leads and through your aerial lead. When audio signal cables such as stereo cables with RCA plugs used between an audio source and an amplifier, small currents may create voltage potentials that can be picked up as noise.

The way to solve the problem is to break the earth connection in the aerial lead with our ground loop isolator; simply plug it in between the aerial socket and your equipment and it'll eradicate the hum (and improve your enjoyment of the sound).

Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.It's not as effective as isolating the supply voltage, though, and you'll need an in-amp with good CMRR. The inductive ground loop will pick the dominant magnetic field in your house, which is usually the mains frequency and its harmonics.

This type of ground loop isolator, for coaxial cables used with over-the-air antennas and cable- and satellite-TV equipment, can eliminate both visual and audible noise.I can assure you that even good (or great) designers, who will inevitably have put a lot of thought into their grounding schemes, still somewhat cross their fingers when they come to connect things up (at least I do, certainly). The third method is to get a USB noise filter (I’ve never seen one for HDMI, but an HDMI adapter could work), which is actually a USB re-transmitter that splits the shield connection. For audiophile-quality goals, it’s definitely not preferred as it introduces another item in the signal path. You'll find multiple promotions on isolator happening daily, so you won't miss out on getting the savings. If not, there's no reason to break up the ground loop (especially since the laptop only has a single ground connection).
