Description

1. The use of high-quality materials, product quality is guaranteed
2. A level for RFI filter DC circuit, through two 50A bridge stack and four 35V2200UF capacitors, filtering AC power in the DC component, to suppress the DC component transformer generated by magnetic saturation or static current increase, and lead to humming
3. Differential mode filtering, two differential inductors, differential mode filtering of the AC power supply to suppress high and medium frequency interference
4.First level common mode filtering, through X2 capacitors and common mode inductors, combined into common mode filtering
5. Two common mode filtering, because of the use of two stages (also known as two sections) filtering, so the effect of noise filtering better. For some users there are fast transient group pulse interference with a repetition frequency of several kilohertz, it can play a suppressing role.

Instructions for use:
Amplifier audio power filter circuit description: the circuit consists of three parts, the first part is RFI DC blocking circuit, the second part is the differential mode EMI filtering, the third part is the common mode EMI filtering circuit.
RFI DC blocking circuit: to eliminate AC AC220V mains due to inverter air conditioners, switching power supplies, refrigerators, chargers and other appliances DC components of the AC interference. RFI DC blocking circuit built using diodes and capacitors to eliminate and block DC components in the utility AC power supply to prevent transformers from magnetic saturation or static current increase due to DC components.

Note: Any DC power on the AC supply usually causes hum from most large toroidal transformer coils, adding RFI DC blocking circuit can significantly improve power quality and eliminate and suppress transformer hum.
This module with the decoder use or amplifier use, can filter the power supply DC component, eliminate and suppress the transformer hum, high frequency noise in the power supply, purify the power supply, can significantly improve the amplifier sound quality, improve the resolution and make the background quiet.
Input GND needs to be connected to the ground of the power line, but also then connected to the chassis shell, depending on the circumstances.
