Car Stereo Ground Loop Isolator RCA Noise Filter

The ground loop isolator helps to eliminate noise caused by ground loops. Ground loops occur in a system when you install two or more audio components that connect to ground at different locations in your vehicle or in your house's wiring system. Because the ground-carrying lines are not perfect conductors, different ground points can have a voltage potential between them. This causes current to flow through your audio system's interconnect wiring causing noise to enter your system. Your ground loop isolator blocks these currents.

This ground loop isolator is ideal for use either in your vehicle's or your home's audio system. In your automobile, the ground loop isolator helps to eliminate engine and alternator noise. In your home, the ground loop isolator can help to get rid of electrical line noise (hum).

1. Points of different electrical potential in the vehicle body (multiple grounding points)
2. These multiple grounding points cause currents to flow over the audio interconnect wire shields with resulting noise.
3. The Ground Loop Isolator blocks these currents
