The sound is not generated shortly after
the power supply is turned on.
This amplifier is equipped with a time muting circuit in order to
separate the output circuit. Therefore, no sound is generated
shortly after the power supply is turned on.
If the volume control is set to a high sound level before the
time muting circuit is canceled, a large sound will suddenly be
generated. Please be advised that the volume control shall be
set to a low level at first and adjusted after the sound comes
out of the speakers.
