(*) This IC can be used without coupling capacitor (C_IN).
If volume slide noise occurred by input offset voltage is undesirable, it needs to use the capacitor (C_IN).
(**) The condenser between the pin 8 and the GND (C11) is for reducing POP noise when the power ON/OFF switch
(SW1) is set to ON/OFF.
