An amplifier system with automatic distortion control including an amplifier provided with a detector between the amplifier output and feedback ports for detecting a nonlinear condition with a balanced differential circuit connected to the detector and feeding a full wave threshold detector which charges a storage capacitor proportionally to the percent clipping of the output signal of the amplifier. The storage capacitor is discharged into an input variable gain amplifier in the amplifier input circuit to reduce the gain for minimizing clipping.
