: Typically delivers around 20W to 50W per channel (depending on the specific circuit configuration and load, often 8Ω).
: The muting pin is often connected to a delay circuit (using a transistor and capacitor) to ensure the amplifier only engages after the power supply has stabilized. Equivalent and Replacement Options stk411-210e circuit diagram
: These pins receive the positive and negative rail voltages. It is critical to use decoupling capacitors (such as 100µF electrolytic paired with 0.1µF ceramic) near these pins to filter out voltage ripples that could cause audible noise. : Typically delivers around 20W to 50W per
