Specification Brand : hiBCTR BulletPoint : Audio Transformers BulletPoint1 : Function The XH - M372 Stereo audio isolator is an audio common ground isolator that effectively suppresses noise caused by common ground for sound sources and receiving devices. BulletPoint2 : Noise transmission mechanism Due to differences in grounding resistance, noise is transmitted into electrical equipment through the ground wire, forming interference. BulletPoint3 : Noise generation cause The grounding points of two devices being different can lead to the generation of common ground noise. BulletPoint4 : Noise manifestation The noise is mainly reflected in car audio, presenting as audio interference, such as a whistling sound, and its frequency changes with engine speed. BulletPoint5 : Limitations It can only eliminate noise and current sound generated by common electricity, and cannot eliminate noise caused by other reasons. Thus, users need to confirm the noise source themselves.

XH - M372 Stereo audio isolator is a vehicle common ground noise - eliminating module for stereo audio.
Connect earphones to car MP3 and car navigation AUX (3.5mm interface). If no noise is heard, common ground causes is confirmed.
Use audio cable to connect battery - powered mobile phone or MP3 to car center console AUX and play music. Noise indicates common ground cause.
Use passive headset on computer, phone on amplifier. If no noise, common ground cause is basic judgment.
After starting the car, the installed amplifier has current sound. Throttle - related noise can be solved by this product.
There is current sound between amplifier and speaker. Install this product between them.
When laptop is connected to projector and amplifier has noise, connect adapter to power supply or use battery. Unplug amplifier or projector to make noise disappear. Add common ground isolator to computer's headphone jack and amplifier to eliminate noise.
