You've installed new receivers or amplifiers in your car, and now you have a noise problem. Noise in your audio system commonly caused by multiple devices ground loop problem. if you are unable to locate the cause, a ground loop isolator can be installed to eliminate ground loop humming and buzzing noise between an audio source and an amplifier. When used with car audio, this isolation circuit goes between the head unit and the amplifier or EQ.

But, all the old ground loop isolators on market are terrible for signal below 100Hz. Huge DISTORTION! Edge designed this smallest and new ground loop isolator MGLI made from High Fidelity Permalloy transformers to minimize signal loss and distortion. Thanks to its super compact design, it can be installed in any tight space. 



•       Eliminates ground loop noise between the audio source and radio. For use with portable devices that have RCA audio outputs, including pre-amp outputs
•       Made from High Fidelity Permalloy Transformers to minimize signal loss, unlike other old ground loop isolators with HUGE DISTORTION under 100Hz. 
•       Close to perfect response of +/- .03 db from 2 to 20,000Hz
•       Super compact design for easy installation in tight space. 
• Split pin RCA connector with pure Oxygen Free Copper spiral shielding wire
