Specification：
Item Type： Loop Noise Isolator
Material： ABS
Working Principle： The working principle of this noise isolator is to achieve clear voicemusic by eliminating the current noise in some car speakershome stereo systems
Determine Whether the Noise is Caused by Common Ground：
1. Use headphones to connect with car MP3 and car navigation AUX (3.5mm interface). If there is no noise in the sound heard from the headphones at this time, you can confirm that the noise of the car equipment is caused by the common ground.
2. Use an o 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 center console of the car, and play the music of the mobile phone, so there is no noise at this time, it can be confirmed that the previous noise was caused by the common ground.
3. Computer, Power Amplifier, o, CD： Use passive headphones to plug in the computer to try to hear whether there is noise, use mobile phone to plug in the power amplifier, and o to tion, if there is no noise in the separate tion, it is basically judged that it is caused by common ground.
4. After starting the car, the installed power amplifier has current noise, and some models will 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 o, you can install this product between the power amplifier and the speaker.
6. When the laptop is connected to the projector and the power amplifier is connected to the power amplifier, there will be noise. You can connect the laptop 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 the power amplifier of the computer can be used. Add a common ground isolator to eliminate noise.
