Circuit for the protection of the diode D1, D2, C5 for filter capacitance, for high frequency back coupling capacitance C6; RP for volume control potentiometer; IC is power amplifier integrated circuit; R1, R2, R3, C2 for power amplifier at the input offset circuit IC, because this circuit for single power supply, power amplifiers IC input dc voltage power supply voltage circuit for 1/2 to work properly; R4-g9 R5, C3, a negative feedback loop, and change the size of the r4-g9 can change feedback coefficient. C1 is input, output coupling capacitance C4 is coupling capacitance; Then there are the circuit perceptual load the speaker, R6, to ensure high frequency stability C7. 2， performance parameters The input voltage:DC≤24V (this suite no rectification, must use the DC power supply, recommend voltage 12 V) Output power: Po = 15 W (RL = 4 Ω) Output impedance:4—8 Ω package included: R1,R2,R3,R4,R5,R6-resistance RP-potentiometer C1,C2,C3,C4,C5,-Electrolytic capacitor C6,C7- capacitor D1,D2-diode X1-Row needles X2,X3-wire holder IC*1 Heat sink *1 PCB BOARD*1 Payment Shipping We accept Paypal, credit card through Paypal.
