Features

• Built-in muting circuit cuts off various kinds of pop
noises.

• Current mirror circuit provides low distortion (THD =

0.08%).

• Pin compatible with the STK4102II series, forming a
series of products with output powers from 15 W/ch to
120 W/ch.

Specified Transformer Power Supply (RP-25 equivalent)

Notes

• Use a constant voltage power supply for the test power supply unless otherwise noted.

• Use the transformer power supply shown in the figure above when measuring the available time for load shorted and the output noise voltage.

• The output noise voltage is the peak value measured with an averaging rms scale volt meter (VTVM). A 50 Hz AC stabilized power supply should be used
to eliminate the effects of AC primary line flicker noise when an AC power supply is used.
