A system for limiting the amplitude of electrical signals applied thereto includes a first feedback loop for reducing the gain of an amplifier to which the input signal is applied and a second feedback loop for providing a frequency dependent signal for returning the amplifier to its original gain. The time which is required for the amplifier to return to its original gain is dependent upon the frequency of the audio signal and the amplifier gain is restored to one of a plurality of fixed rates.
