Redesign Mini Subwoofer STA540 + Tone Control, Project pertama aku yang di publish. Versi SMD sedang dalam proses. Jika ingin memberikan saran dan kritik dipersilahkan, maklum masih newbie

IC STA540 DC 12-20V 4A AC 9-15V 4A 2X 11W + 1X 38W 4OHM 2X 7W + 1X 20W 8OHM

Resistor 1/4W 5% R1, R3 = 2.7K R2 = 3.3K R4, R11, R13 = 47K R5, R12, R15, R19, R20 = 8.2K R6, R7 = 1K R8 = 68K R9, R10, R14, R18, R23, R26 = 10K R16, R17 = 22K R21, R23 = 1.8K R22, R24 = 6.8K P1, P3 = 47K atau 50K P2 = 100k P4 = 47K atau 50K

Capacitor C1 = 6800µF C3, C4,C14, C19, C30 = 10µF C5, C7, C8, C9, C10 = 4.7µF C6, C28, C31 = 100µF C22 = 0.47µF C33, C34 = 1000µF C2, C15, C20, C32 = 100nF C11, C12 = 100pF C13 = 220nF C16, C26, C27 = 100nF C17, C18 = 6.8nF C21, C23 = 4,7nF C24, C25 = 33nF C29 = 1nF

Semicondutor B1 = Dioda retific 200V/2A IC1 = 7812 12 Volts IC2, IC3 = LM4558N IC4 = STA540 LED = Led 5mm

Conectores XX = Conector 9 Pin
