To minimize or remove radio interference in routers and cascade antenna systems that connect multiple antennas.To protect humans from being shock by electric current when using electrical devices,.To remove the engine humming sound that filters into the audio output of a car radio,.To eliminate interference or noise from speaker systems with multiple speaker units,.Some of the most common uses of ground loop isolator are: Where is a ground loop isolator used?Īpart from removing noise from an audio signal, a ground loop isolator offers a lot to electrical systems, in particular, systems with audio and video capability. Therefore, it removes electrical noise within the audio circuitry of a radio receiver.Ī ground loop isolator consists of an input, an output, and a transformer in between. In simple terms, it removes electricity from sound and vice versa within a system. This device can eliminate interference by balancing the voltage across all ground points within a circuit to the same value.Īs a result, it removes any potential difference that may exist within the ground circuitry. Through the electric isolation of all-metal cases of devices around the radio receiver.Ī ground loop isolator is an electrical device that minimizes interference within a ground loop system by reducing the paths to the ground to only one way.The use of balanced audio devices and cables all connection points,.Minimization of connection impedance (resistance) by using high-quality wires for both audio and power connections,.Nonetheless, there are other ways of reducing ground loop noise: Installing a ground loop isolator is the best way of getting rid of ground loop noise. The capacitance from a power transformer that feeds the circuit, which powers a radio receiver, can introduce ground loop noise onto the audio circuitry ground system.Magnetic capacitance or inductance on a signal cable can cause ground loop noise.This type of noise generated from the difference in voltage is the most severe and can be hard to mitigate. ![]()
