Connect to a split DC power supply. Ensure the voltage does not exceed the maximum rating (typically around ±54V to ±65V for this series variant).
Before diving into the numbers, here are the standout features summarized from the official datasheet: stk411210e datasheet
Thin or "crackling" sound usually indicates a failing internal stage or dried-out external electrolytic capacitors. Connect to a split DC power supply
: Requires a substantial external heat sink for prolonged use, as the hybrid IC generates significant thermal energy during high-output operation. stk411210e datasheet
