Stereo Audio Signal Isolation Audio Common Ground Isolator Eliminate Current Sound

1.Product description

2.Features

1.Parts selection: Two independent audio transformers are used, and the transformer material is made of aerospace materials.

2.High sensitivity and high reducibility, 10-20dB higher sensitivity than similar low-end transformers, full timbre and pure sound quality.

3.Circuit design: stereo dual channel independent design, circuit board specifications: 45mm*30mm? Very small, suitable for small Spaces such as car interior installation.

4.Connection mode: There are two connection modes, which can be input and output through 3.5MM headphone socket, or directly connected through two blue wiring sockets.

5.Main functions: eliminate current sound. The common ground isolation audio transformer eliminates the current sound brought by the AUX common ground, and the output and output ground wires are isolated through the transformer, and there is no common ground.

3.Introduction

This product is an audio common ground isolator, effective for noise caused by common ground between audio source and receiving equipment.
To put it simply, the common ground is that the ground point of the two electrical appliances is not at the same point, because of the difference in grounding resistance, the noise is transmitted through the ground wire into the electrical equipment, forming interference. Because the ground points of the two devices are different, it is possible to produce common ground noise. In the car audio, there is a kind of audio interference, like whistling, the frequency of this noise will change with the speed of the engine.
Therefore, this product can only eliminate the noise and current sound of common electric and ground products, and can not eliminate the noise caused by other reasons, so it is necessary to confirm the source of noise in person.

4. How to determine if noise is caused by common grounding
