This product is the audio common ground isolator, for the audio source and amplifier equipment because the two grounding points are not in the same point, bringing the difference in ground resistance, making the noise through the ground into the power equipment inside, the formation of interference, performance in the car audio, is a high-frequency signal interference, and the sound will change with the engine speed change;
The following judgment methods for reference:
1. computers, amplifiers, stereos, CDs and other household occasions, the use of headphones to try to listen to the noise, separate listening to the two are no noise, the basic decision is a common ground caused;
Peal start the car, the installation of the amplifier has a current sound, some models will also appear the greater the throttle, the greater the current sound, most of this product can solve this problem;
3. Use headphones and car MP3, car navigation headphone hole or signal output connected, note that not the speaker interface), if the sound heard from the headphones at this time no noise, it is basically possible to determine the noise is caused by common ground interference;
4. Use the audio cable to cell phones, or MP3, (note that cell phones, MP3 do not external any power supply), and the car center console AUX connected to play music, so when there is no noise, it can be confirmed that the noise is caused by common ground interference;
5. laptop connected to the projector and amplifier noise, you can use the battery power through the laptop, at this time unplug the amplifier noise disappeared, or unplug the projector the same noise disappeared, then you can add the headphone hole in the computer and the amplifier between the isolator to eliminate noise.
1. This product uses computer-aided, spectral analysis technology, more pure and thorough filtering than common filtering products on the market, in view of the different scenes of use, noise caused by different reasons, this product can not guarantee 100% effective!
⒉. When you encounter the following problems, perhaps you can consider our filtering products:
a. When the audio source and car speakers or home audio system using the same power supply ground loop improperly generated after the hum noise, the product can effectively isolate the audio and power grounding to avoid the impact of the post-stage on the pre-stage, so that the sound pure and natural;
b. car audio system or new subwoofer equipment due to improper alignment of interference caused by stepping on the gas pedal, the speaker buzzing noise, and the size of the noise changes with the size of the throttle;
3. The following cases are not recommended for purchase, can not eliminate the problem of noise:
a. If the original audio system such as car CD or navigation without the addition of other equipment there is hissing white noise, then the product is invalid, this is the problem of the head itself;
b. Non-co-ground noise, such as electromagnetic interference;
