: 210 Watts total output capability under ideal load and voltage distribution. stk411210e datasheet

Optimized for the full audible range (20Hz to 20kHz).

If you measure high DC voltage at the speaker terminals, the internal output transistors are likely shorted. Left and Right channel inputs, typically coupled through

: Includes internal circuitry to minimize "pop" noise during power-on/off sequences. Constant Current Drive

: Audio output pins routed directly to the speaker terminals via a protection relay. Essential Design and Thermal Guidelines Heat Management If you measure high DC voltage at the

According to technical documentation for the STK411 series, the STK411-210E

The STK411-210E belongs to a series (including STK4102II and STK4101V types) that are often pin-compatible, allowing for scalable design (6W to 50W) without redesigning the PCB.
