You can connect the notebook to the adapter power supply or use the battery. When the notebook computer is connected to the projector and the power amplifier is connected to the power amplifier, there will be noise.There is current sound between the power amplifier and the speaker or audio, you can install this product between the power amplifier and the speaker.After starting the car, the installed power amplifier has electric current noise, and some models also have the situation that the greater the throttle, the louder the current noise, this product can solve this problem.Computer, power amplifier, audio, CD: use passive headphones to plug in the computer to try to hear whether there is noise, use the mobile phone to plug in the power amplifier, audio to audition, if there is no noise in the separate audition, the basic judgment is caused by the common ground.Use an audio cable to connect a battery-powered mobile phone or MP3 (note that the mobile phone and MP3 should not be connected to any power source in the car, such as a telephone), and the AUX of the car center console, and play the music of the mobile phone, so there is no noise, It can be confirmed that the previous noise was caused by the common ground.If the sound heard from the headset is no noise at this time, you can confirm that the noise of the car equipment is caused by the common ground.

In the car audio system, there is a kind of audio interference, like a buzzing sound similar to a whistle. Because the ground points of the two devices are different, common ground noise may be generated. Due to the difference in grounding resistance, noise is transmitted into the electrical equipment through the ground wire, causing interference. To put it simply, common ground means that the grounding points of two electrical appliances are not at the same point. This product is an audio common ground isolator, which is effective for noise caused by common ground between the sound source and the receiving device. ![]() Please confirm the source of the noise before purchasing.Īs everyone has different expectations of the isolation effect and different senses, some customers think it is good, some customers feel it is bad. The noise caused by non-common ground cannot be filtered by this model, such as electromagnetic interference, etc. Easy to use, just plug and play, no battery needed]: Small and portable, this small tool does not take up much space and is easy to take away.Pure sound quality: There is no damage of rock music, giving you a better experience, and it can be used on mono.Eliminate hum: Eliminate the hum noise caused by the ground loop when the audio source and (some car speakers/home audio systems) use the same power supply, so as to achieve clear music enjoyment, and the excitement blooms.Works with any portable device that has 3.5mm audio jacks, for your car audio system, home stereo, when grounding issues persist.Īlso used with a bluetooth receiver, bluetooth hands-free car kit in your car audio system, home stereo. The working principle of this noise isolator is to achieve a clear speech, music by eliminating the current noise in some car speakers, home stereo systems.
