rail value), the internal output transistors are shorted. The IC must be replaced.
The STK412-230 belongs to the STK412-000 series, which is characterized by its architecture. Unlike standard Class AB amplifiers, Class H circuits use a "shift power supply" that dynamically adjusts the voltage supplied to the power transistors. This significantly reduces heat dissipation and improves overall energy efficiency, making it a popular choice for high-power consumer audio systems and professional sound equipment.
