Small cars and other interior installations.Parts Selection: Two independent audio transformers are used, and the transformer material is selected from aerospace materials.High sensitivity and high reduction, 10-20DB higher sensitivity than similar low-end transformers, full tone, pure sound quality.Line design: stereo two-channel independent design, circuit board specifications: 45MM X 30MM, very small, suitableConnection method: Two connection methods, which can be input and output through a 3.5MM headphone jack, or can be directly wired through two blue wiring jacks.Main function: Eliminate current sound. A common ground-isolated audio transformer eliminates current noise from the AUX common ground. The output and output ground lines are isolated by the transformer and there is no common ground.

What is common land?
This product is an audio common ground isolator, which is effective for the noise caused by the common ground for the audio source and the receiving device.
To put it simply, a common ground is that the ground points of two electrical appliances are not at the same point. Because of the difference in ground resistance, noise is transmitted through the ground wire into the power equipment, forming interference. Because the two devices have different grounding points, common ground noise may occur. In the car audio system, there is an audio interference, which is almost the same as the whistling sound. The frequency of this noise will change with the speed of the engine.
Therefore, this product can only eliminate the noise and current sound caused by the total common-electricity products, and cannot eliminate the noise caused by other reasons. Therefore, you must confirm the source of the noise yourself.
Determine whether the noise is caused by common ground:
1. Use the earphone to connect with the car MP3 and car navigation AUX (3.5mm interface). If the sound heard from the earphone is no noise at this time, it can be confirmed that the noise of the car device is caused by the common ground.
2. Use the audio cable to connect the battery-powered mobile phone, or MP3 (note that the mobile phone, MP3 is not connected to any power source on the car, such as a telephone), and the AUX of the car center console, and play the music of the mobile phone. Noise can confirm that the noise was caused by the common ground.
3. Computer, amplifier, stereo, CD: Use a passive headset to plug in the computer to hear if there is noise, use the phone to plug in the amplifier, audio audition, if there is no noise, the basic judgment is caused by the common ground.
4. After starting the car, the installed amplifier has a current sound. In some models, the throttle is larger and the current is louder. This product can solve this problem.
5. There is a current sound between the amplifier and the speaker or the sound. This product can be installed between the amplifier and the speaker.
6. When the laptop is connected to the projector and the amplifier is connected with noise, you can connect the adapter to the power supply or use the battery. At this time, unplug the amplifier and disappear, or unplug the projector and the noise will disappear. Then you can use the headphone jack and amplifier of the computer. Add a common ground isolator to eliminate noise.
