Note that the input voltage *multiplier signal cannot be higher than the supply voltage. Please select the power supply voltage reasonably. The higher the voltage, the louder the signal. It's not easy to cut out. If the signal is not very large, lower voltages will work. Please use a high quality power supply with low ripple as it is not a power supply that is likely to generate hum.
