, and Ground). Large electrolytic capacitors are essential for filtering ripple and providing peak current for bass transients. Go-Radio.ru Installation and Usage Tips Heat Dissipation
Add a small-signal NPN transistor between Pin 1 and GND. When the base is driven high, the transistor shorts the input to ground, providing anti-thump on power-up. stk403-070 circuit diagram
: Driving speakers below 4Ω can draw excessive current and destroy the internal output transistors. , and Ground)
: Uses coupling capacitors to block DC signals and resistors (often 56k or similar) to set input impedance. Feedback Loop stk403-070 circuit diagram
