-Vcc (Pin 4) and +Vcc (Pin 1) from a dual-polarity supply. It improves efficiency by switching the supply voltage

The "Shift Power Supply" technology (Class H) distinguishes the STK412 series. It improves efficiency by switching the supply voltage based on the input signal level, reducing heat dissipation during low-volume playback. One of its standout features is the two-channel
