Questionandanswer:
1.Howtochooseapowersupply?
Thepowersupplywiththeboardiscritical.Thehigherthevoltage,thehigherthecurrentandthebettertheoutputpower.
Ifyouonlyhave12V1A,youcanbringa3-4inchspeaker.Ifyouare19V5Aorabove,thereisnoproblemwith8-10inches,
andthepowersupplymustbehighlyvalued.Ifthevoltageistoolow,thesoundwillbedistortedafterthesoundisamplified.
