Don’t remind
Buyers should judge whether the noise source of their equipment is caused by the common ground. If the noise of the equipment is not clear, If you buy this product due to source reasons, it may not be able to play a good coupling and isolation role. At this time, there will be no refund or exchange. Again, this product can only solve the AC noise caused by common ground interference
How to judge Is the noise generated from a common ground?
For in-vehicle computers, in-vehicle navigation, and in-vehicle devices, the frequency interfaces of these devices are connected to the port on the center console of the car through audio cables. At this time, when the cigarette lighter is used to power the in-vehicle computer and other equipment, this is the in-car audio system. There will be communication noise. Please follow the method below to determine whether it is caused by the common ground.
Find a passive headset or the headset on your mobile phone and connect it to the port of the car computer or other equipment. Use the headset to listen to see if it is still there. If there is noise, if there is no noise at this time, it can be basically determined that the connection between your device and the car body is caused by the common ground
Just find a passive one, such as a mobile phone, or a mobile phone. At this time, the mobile phone or battery is required to provide power. If there is any connection to the car's power supply, connect it to the car's center console and listen to the music played on the mobile phone to see if there is any noise in the car. If there is no noise, it means that the original connection is noise caused by the common ground.
If other than the above conditions occur, The noise is not caused by multiple devices sharing the same ground. For example, it may be caused by the fault of the power amplifier board itself or the sound source signal and connection wiring. At this time, using this isolation board cannot solve the noise problem. Please purchase it. Check by yourself beforehand~

Product overview
Typically, audio or stereo The voltage of the shielding layer of the signal transmission cable is The signal is severely distorted and interferes with low-frequency AC
and high vehicle sparks
.
When the audio signal transmission distance exceeds
, it is easy to produce a high ground loop voltage. If the ground
voltage is too high, it may even cause the signal source or receiving equipment to If it is burned, it may endanger the service life of the vehicle battery in severe cases.

Customer issues
When the laptop is connected to the projector and power amplifier at the same time, there is a buzzing sound. If the laptop is not connected to the power adapter and the battery that comes with it is used, there will still be buzzing sound. However, as long as the projector is unplugged, there is no current sound. Replace the company's isolator. normal.
