Lower input source volume or increase the value of feedback resistors. Thermal runaway or short circuit on output.

This filterless Class D architecture drives speakers directly without bulky low-pass LC filters. Keep component leads as short as possible to minimize electromagnetic interference (EMI). 3. Medium-Power Hifi Projects (10W to 50W)

Avoid PDFs that are just a blurry scan of a 1980s magazine. Look for documents with ground planes , star grounding notes, and decoupling capacitor values. If the author mentions "hum reduction," you have found a practical engineer.
