How to reduce noise on SD Music +

Dear Customers,

 

SD Music+ having some noise and here is a way to reduce noise.

The noise is coming from power source and YM2413.

This is a type of filter on output and input.

Please refer to the photo and apply two components.

One is 10K Ohms resistor and the other is a 0.022uF(223) capacitor.

(Similar value capacitor and resistor also work for this purpose)

It would help to reduce noise on sound.

Thanks a lot.
