I need zero volts output at no signal of the peak detector circuit so I can drive a audio display level circuit that uses the lm3915. What voltage does potentiometer r3 has to be set at and what would be the value of r4 to achieve this? My output without r3 or r4 is 47 millivolts and I need it to go lower to zero volts if possible. I plan to show the level of an audio line amplifier with LED display using the lm3915.
