Protection Circuit,
© After turing on the power of the Sa-9900,
5 ~ 8 seconds will elapse before sound is
obtained from the speakers. This is due to the
operation of the built-in protection and muting
circuit. It serves to both prevent switching noise
when the power is tumed on and off, and
protect the speakers in event DC oceurs in the
output,
© Operation of the internal relay during playing
will cause continuous a clicking neise.
'This would most likely be caused by speaker
terminal shorting or overload (used speaker
impedance less than 49 }.'The protection cixcuit
fanctions automatically in this type of case to
disconnect the speaker terminals and safeguard
the transistors and speakers. The circuit is self
rosetiing and after the cause of trouble hes been
corrected, it will return to normal condition.
