A small inductor (roughly 1µH to 3µH, often made by wrapping 10–15 turns of magnet wire around a 10Ω resistor) is placed in series with the output line to isolate capacitive speaker cable loads.
The STK411-210E leverages SANYO's proprietary Insulated Metal Substrate Technology (IMST), which integrates discrete power transistors and driving circuitry onto a highly thermally efficient substrate. : Delivers clean amplification into standard speaker loads. stk411-210e circuit diagram
