Ground loop noise isolator, also known as a ground loop isolator or noise supressor, is an electronic device that eliminates unwanted currents and voltage in audio equipment caused by ground loops.

Ground loops occur when two pieces of equipment are interconnected by multiple paths, each with its own electrical potential. The most common example is audio components connected to each other through a common AC power source.

When audio signals pass through a wire, some small amount of current flows along the wire. This current is called an I/R (current/resistance) current because it is a result of the resistance of the wire. A piece of wire has some resistance to current flow due to its physical geometry and material makeup (see Ohm’s Law).

This means that when you send electricity down a wire, part of it will flow back up the same wire in the opposite direction – this is called capacitive reactance. There are two kinds: inductive reactance (caused by coils) and capacitive reactance.

Things to consider before buying a best ground loop isolator

The quality of the loops isolator

Before you buy a ground loop isolator, you should check the quality of the device. Here’s what to look for:

  • A good ground loop isolator has no detectable noise at low frequencies. This means that if you play music or power an amplifier with your equipment plugged into both sides of the ground loop isolator, your music won’t sound different than it did before using the ground loop isolator. If there is noticeable noise at low frequencies using this method, then either your equipment isn’t isolated properly or there is some kind of problem with the ground loop isolator itself.
  • A good ground loop isolator works well in all configurations and environments imaginable. For example, if one side of your audio setup is powered by batteries and another side is connected to a wall outlet (or vice versa), then plugging them into each other should not cause any problems whatsoever—and vice versa! The same goes for equipment used in professional studios versus home recording setups: if an engineer types up some notes while listening to his favorite song on his computer through headphones only bought from Best Buy instead-of-Amazon (and why would anyone do something so silly?), it should still work just fine when he unplugs his headphones from their jack back into their socket on top of his desk—even though they were made cheaply enough that they started falling apart after only two weeks’ worth use!

The material used

The material used in ground loop isolators is important. There are many different types of materials and each type has its own set of pros and cons.

  • Copper: Copper is one of the most common types of materials for ground loop isolators because it’s affordable, easy to work with, and has good conductivity. However, copper can corrode if not treated properly or if exposed to water or moisture, which means that you’ll have to regularly clean your device so as not to damage it further by rusting or tarnishing inside parts due to corrosion caused by humidity levels getting too high inside your home/office building where this equipment will be kept (i.e., near windows).
  • Aluminum: Aluminum is another popular choice among manufacturers because it’s lightweight and cheaper than other metals used in similar products (like steel). However unlike steel which tends towards being more durable over time than aluminum due its higher conductivity level; aluminum won’t last as long under constant stress like other metals would under similar circumstances–so keep that in mind when shopping around for items made out only from these two options! If possible try looking into other options such as composites made from both these materials together–this should help reduce costs while still offering quality performance over time!

Size, shape, and design

Size, shape and design are the three main things you should consider when choosing a ground loop isolator.

When it comes to size and shape, it’s important that they are not too big or too small for your particular setup. A good size is one that will fit comfortably in your space available while still allowing easy access to all its ports and buttons. Also, make sure the design is right for what you need it for; some models may look better than others but may not be as functional for your needs so keep that in mind when making your final decision!

Another factor worth considering is whether or not you have any special needs regarding materials used in making these devices (such as if there’s any metal near where this device might end up). If so then make sure whatever product fits those needs best before buying anything else because nobody wants an expensive piece of hardware sitting unused just because it doesn’t work properly due to its inability meet certain conditions such as being made out of certain materials only available at one store etcetera…

Isolator and sound quality

A ground loop isolator should not affect the sound quality. That’s why you have to make sure that it is designed for audio signals and not for data or power, because there are different requirements for each type of signal.

If you don’t know what equipment you need, we strongly recommend consulting with a professional to help guide your decision on which ground loop isolator will best suit your needs.

Compatibility with other devices and accessories

In order to get the most out of your equipment, it’s important that you check the compatibility of your device before buying an isolator. If you don’t, you may find yourself with a product that doesn’t work as intended or at all. The best way to make sure everything works together is by checking the ports on each device and seeing if they match up with one another. For example:

  • If your computer has USB ports but the isolator does not, then you won’t be able to connect them properly
  • If your GPS receiver has an audio jack but the isolator does not, then neither will be able to communicate with each other

Durability, longevity, warranty, and guarantee

One thing you should consider is the durability, longevity and warranty of the ground loop isolator. As with any product, it’s important to understand how long it will last and whether or not there are any guarantees being offered by the manufacturer. You’ll also want to see what kind of reputation this company has for customer service.


In conclusion, ground loop isolators are simple and easy to use devices that provide solutions for grounding problems. They can be used in many different applications and are an essential part of any electrical system. Ground loop isolators are available at hardware stores or online retailers like Amazon. If you’re looking to buy a ground loop isolator, it’s recommended that you do your research before purchasing one from any retailer so that you can ensure that the device will meet all of your needs.
