So as to improve the sound quality of TDA2030A power amplifier? Who has the circuit diagram? Solve. .

I don't know if you have any ready-made power amplifier or TDA2030A power amplifier components. If you have a ready-made power amplifier and want to improve the sound quality, start with the power supply and connect a 0. 1UF ceramic chip or polyester capacitor in parallel with each rectifier diode. If the filter capacitor is 2200UF or less, replace it with 4700~ 10000UF, and add a ceramic or polyester capacitor of 0. 1UF, which can effectively reduce the interference of the power supply. Then, replace the audio input capacitor with a non-inductive capacitor. If any ceramic capacitor is found in the circuit except the power supply part, it will be replaced with polyester capacitor. Finally,

If you have TDA2030A power amplifier module at hand, you can refer to the circuit diagram here /i? tn = baiduimage & ampct=20 1326592。 cl = 2 & amplm=- 1。 fr = & ampsf= 1。 fmq = & amppv = & ampic=0。 z = & ampse = 1 & amp； Show tab = 0&FB = 0 & Width = & Height = & Face = 0 & Style = 2 & Ampb7% C5% B5% E7% C2% B7% CD% BC&; s=0
