depending on the load, the STK412 series generally supports high-voltage operation up to ±85Vplus or minus 85 cap V [5.8, 5.17].
Maximum supply voltage of up to $\pm$63V, typically requiring a stable dual-rail power supply. Amplifier Class:
Unlike standard Class AB amplifiers, the STK412-230 uses a built-in shift power supply circuit. It detects the input signal level and switches between low and high supply voltages, which significantly reduces power loss in the output transistors. Stk412-230 Datasheet Pdf
Class H (Shift Power Supply), which switches supply voltage based on the input signal level to reduce heat and improve efficiency. Package Type:
For audiophiles, this is the most scrutinized metric. The STK412-230 datasheet typically lists THD as a percentage. depending on the load, the STK412 series generally
Compact SIP18 (18-pin Single In-line Package) or HYB-18 .
Found in vintage and modern home theater receivers from brands like Sony, Pioneer, and AIWA. It detects the input signal level and switches
The STK412-230 requires only a few external components per channel:
