The three-stage composite (1-stage differential mode + 2-stage common mode) EMI electromagnetic interference filter circuit, due to the use of three stages (also known as three sections) of filtering, achieves a better effect in eliminating noise.
For the problem of rapid transient group pulse interference with a repetition frequency of several kilohertz existing in some user sites, it can play a suppressive role.
This module can be used in conjunction with a decoder or a power amplifier. It can filter out the DC components of the power supply, eliminate and suppress the humming sound of the transformer, as well as the high-frequency noise in the power supply. It can purify the power supply and significantly improve the sound quality of the power amplifier, enhance the resolution and make the background quiet.
The input GND needs to be connected to the ground wire of the power supply line. Additionally, it can also be connected to the case of the machine depending on the specific situation.
