Ground Loop Noise Isolator

Anti-interference Ground Loop Noise Isolator Safe Accessories Clear Sound Car Audio Aux With 3.5mm Cable Home Stereo Portable

Working Principle:

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.

Compatible Models:
Works with any portable device that has 3.5mm audio jacks, for your car audio system, home stereo, when grounding issues persist.
Also used with a bluetooth receiver, bluetooth hands-free car kit in your car audio system, home stereo.

1. 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.
2. Pure sound quality: There is no damage of rock music, giving you a better experience, and it can be used on mono.
3. 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.

Unable to eliminate the noise problem:
The noise caused by non-common ground cannot be filtered by this model, such as electromagnetic interference, etc. Please confirm the source of the noise before purchasing.
As everyone has different expectations of the isolation effect and different senses, some customers think it is good, some customers feel it is bad.
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.
To put it simply, common ground means that the grounding points of two electrical appliances are not at the same point. Due to the difference in grounding resistance, noise is transmitted into the electrical equipment through the ground wire, causing interference. Because the ground points of the two devices are different, common ground noise may be generated. In the car audio system, there is a kind of audio interference, like a buzzing sound similar to a whistle. The frequency of this noise will vary with the engine speed.
Therefore, this product can only eliminate the noise and current sound caused by the common electricity and common ground products, but cannot eliminate the noise caused by other reasons, so you need to personally confirm the noise source.

Determine whether the noise is caused by common ground:

1. Connect the headset to the car MP3 and AUX (3.5mm interface) of the car navigation. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. When the notebook computer is connected to the projector and the power amplifier is connected to the power amplifier, there will be noise. You can connect the notebook to the adapter power supply or use the battery. At this time, the noise disappears when the power amplifier is unplugged, or the noise disappears when the projector is unplugged, then the headphone jack and power amplifier of the computer Add a common ground isolator to eliminate noise.
