Integrated amplifier modules like the STK411210E typically implement biasing networks to establish Class-AB operation: small quiescent current to reduce crossover distortion while limiting dissipation. These biases rely on temperature-compensated diode drops or transistor Vbe references embedded in the module. stk411210e datasheet
