This product is an audio common ground isolator, which effectively suppresses the noise caused by the common ground for the sound source and the receiving device.
So what is the common ground? To put it simply, the ground point of the two electrical appliances is not at the same point. 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.
Therefore, this product 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.
Determine if noise is caused by common ground:
1. Use the earphone to connect with the car MP3 and car navigation AUX (3.5mm interface). If the sound heard from the earphone is no noise at this time, it can be confirmed that the noise of the car device is caused by the common ground.
2. Use the audio cable to connect the battery-powered , or MP3 (note that the , MP3 is not connected to any power source on the car, such as a telephone), and the AUX of the car center console, and play the music of the . Noise can confirm that the noise was caused by the common ground.
3. Computer, amplifier, stereo, CD: Use a passive headset to plug in the computer to hear if there is noise, use the phone to plug in the amplifier, audio audition, if there is no noise, the basic judgment is caused by the common ground.
4. After starting the car, the installed amplifier has a current sound. In some els, the throttle is larger and the current is louder. This product can soe this problem.
5. There is a current sound between the amplifier and the speaker or the sound. This product can be installed between the amplifier and the speaker.
