Ensure all ground connections (input, power, speaker) meet at a single point to prevent ground loops. stk413-430 circuit diagram
Resistors and capacitors connected between the output and input to set the closed-loop gain. Power Supply Stage: High-value filter capacitors ( recommended) to ensure a clean ±Vccplus or minus cap V sub c c end-sub supply and minimize hum.
: Pin 6 controls the internal muting transistors. Leaving it floating may cause the IC to stay in standby or produce severe turn-on pops. Connect this through a small RC delay circuit to the positive rail so the amplifier turns on smoothly a few seconds after power is applied.
