A True RMS converter (LTC1967) monitors the output signal amplitude and provides a proportional dc feedback voltage. This dc voltage contols an LT1256 fader circuit which linearly selects the amount of signal from two amplifier stages. One amplifier attenuates the input signal by 4 while the other amplifer gains up the signal by 4. Small input signals will be amplified while large input signals will be attenuated within a range of +/- 12dB.
