! ! ! ! Operation notes
(1) Operating power supply voltage range
As long as the operating power supply voltage and ambient temperature are kept within the specified range, the basic
circuits are guaranteed to function, but be sure to check the constants as well as the element settings, voltage settings,
and temperature settings.
(2) Bass filter
