Description

Ground Loop Isolator RCA twin Plugs to Twin RCA Sockets from AV:Link.

AV:Link Ground Loop Isolator RCA – Ground Loop Isolators are designed to eliminate unwanted earth hum. They do this by isolating the ground between two pieces of audio equipment. Therefore; ground loop isolators are used in a variety of electrical systems. They are especially used in audio and video devices. Also; most speaker systems use a ground loop circuit to connect two or more speakers together. This is because the voltage difference between them; is often responsible for an audible hum heard over the audio.

What does a Ground Loop Isolator do?

A ground loop isolator prevents interference in a ground loop circuit. So; a ground loop circuit is one in which two or more circuits are connected to the same ground wire. Ideally; all circuits in a ground loop circuit have the same voltage potential. However; if the ground wire has significant resistance and current, the voltage of the second circuit will be slightly lower than the first; causing a voltage difference that makes the ground wire no longer have a ‘ground potential’. This is known as interference and can be hazardous; inefficient; and a nuisance in many electrical systems.

How Ground Loop Isolators Work?

Ground loop isolators prevent interference in electrical ground loop circuits. They do this by using a small transformer that steps voltages from each circuit in a ground loop up or down; depending on whether the voltage difference is positive or negative. Ground loop isolators have a 1:1 ratio; this means that they produce an output that is equal to their input. So; this allows the ground loop isolator to block any voltage spikes that may interfere with the circuit’s electrical signals.

Applications;

Ground loop isolators are used in a variety of electrical systems; especially in audio and video devices. Most speaker systems use a ground loop circuit to connect two or more speakers together. This is because the voltage difference between them; is often responsible for an audible hum heard over the audio. This hum can also be heard in car stereo systems; in which the hum’s frequency depends on the engine’s RPMs. Also, interference can be much more critical than this. However; in these such cases; transformers and other electrical supply systems use a ground loop to prevent users from being shocked! There are also other uses for the ground loop isolator; they are used in antenna systems and routers that use more than one antenna. This is to prevent radio interference from the device itself.

The advantages of using a ground loop isolator;

Ground loop isolators will prevent unwanted noise in audio and video systems; as well as the hum that a car alternator creates. They will also prevent hazardous interaction between users and high-voltage electrical systems that are meant to be safe. Also, they are not expensive; ground loop isolators are fairly low-cost and can mean the difference between a high quality electrical circuit and a poor one.
