[STK4050 II ]
type stereo sets
• Constant-current circuit to reduce supply switch-on and
switch-off shock noise
• External supply switch-on and switch-off shock noise
muting, load short-circuit protection, thermal shutdown
and other circuits can be tailored-designed.

Notes.
All tests are measured using a constant-voltage supply unless otherwise specified.
Output noise voltage is measured using the transformer supply specified below.
The output noise voltage is the peak value of an av erage-reading meter with an rms value scale . The noise v oltage w a v ef orm does not inlcude any pulse noise.
