Description
XH-M372 Stereo Audio Isolator is an audio common ground isolator, which effectively suppresses the noise caused by the common ground for the sound source and the receiving device..Due to the difference in grounding resistance, noise is transmitted into the electrical equipment through the ground wire to form interference..Because the grounding points of the two devices are different, it is possible to generate common ground noise..The noise is mainly reflected in the car audio, that is, there is an audio interference, like the whistling sound, the frequency of this noise will change with the engine speed..It can only eliminate the noise and current sound generated by the common electricity, and can not eliminate the noise caused by other reasons, so you need to confirm the source of the noise yourself.
