High-power audio requires thick copper traces on your PCB to handle high current. Keep the signal ground and power ground strictly separated until they meet at a single "Star Ground" point to eliminate ground loops and background hum. 5. Troubleshooting and Best Practices What do you currently have available
Utilizing a split-rail supply eliminates the need for a massive output coupling capacitor, significantly improving low-frequency bass response. This circuit features built-in short circuit and thermal shutdown protection. Adequate heatsinking is mandatory for stable operation. Essential Building Blocks in Audio Design High-power audio
Switching or digital amplifiers. They utilize Pulse Width Modulation (PWM) to achieve up to 90% efficiency, making them ideal for portable, battery-powered devices. 2. Essential Tools and Components
