Frequently asked questions:
What is common ground?
This product is a common ground audio isolator, for the audio source and receiving equipment because of the common ground noise caused by effective.
To put it simply, the common ground is the ground point of the two appliances are not in the same point, due to the difference in grounding resistance, so that the noise is transmitted through the ground into the inside of the equipment, forming a thousand disturbances. Because the two equipment grounding point is different, it is possible to produce a common ground noise. Performance in the car stereo, there is a kind of audio interference, like whistling sound, the frequency of this noise, will change with the engine speed change. This product can only eliminate the noise and current sound due to common electricity and common ground products, and can not eliminate the noise caused by other reasons, so you need to personally confirm the source of noise.

Determine whether the noise is caused by the common ground:
1, using headphones and car MP3, car navigation AUX (3.5mm interface) connected, if the sound heard from the headphones at this time no noise, then you can confirm that the noise of car equipment is caused by common ground.
2, use the audio cable to battery-powered cell phones, or MP3 (note that cell phones, MP3 do not connect with any power supply in the car, such as telephone; and the car's center console AUX connected, and play the phone's music, so when there is no noise, then you can confirm that the past noise is caused by the common ground.
3, computer, amplifier, audio, CD: use passive headphones plugged in the computer to try to listen to the noise, use the phone plugged in the amplifier, audio to try to listen, if the two are separate to try to listen to no noise, the basic decision is caused by the common ground.
4, after starting the car, retrofit or modified amplifier current sound, some models will also appear the greater the throttle, the louder the current sound, this product can solve this problem.
5, the notebook computer connected to the projector at the same time connected to the amplifier appears to produce noise, can be connected to the adapter power through the notebook or with the battery, at this time unplug the amplifier noise disappeared, or unplug the projector the same noise disappeared, then you can add a common ground isolator between the computer's headphone hole and the amplifier to eliminate noise.
If there is noise other than the above, it is not generated by multiple devices together, such as the amplifier board may be its own fault / bottom noise, or the source signal and connection line caused by these aspects, at this time the use of this isolation board can not solve the noise problem, please buyers friends before buying their own troubleshooting, this is very important!
