: 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
: Features a built-in substrate designed to withstand temperatures up to 125°C , which significantly reduces the size requirement for external heat sinks. 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. : The muting pin is often connected to
