Constituting simple LM3915 audio power meter circuit - schematic

18k speaker if the internal resistance 16 when, Rx take 30k Levin show a use of such IC AC input signal amplitude more sophisticated method is to use a half-wave AC signal converter will be changed to a DC signal, and then the DC signal is then fed to the input of the IC.
