A compartmental gain limiter and a controlling method thereof. The compartmental gain limiter connects to an audio amplifier, which has a gain value and generates an output signal according to an input signal and the gain value. The compartmental gain limiter includes a comparator and a clamper. The comparator having a critical value receives the output signal and outputs a driven signal when the output signal is greater than the critical value. The clamper receives the driven signal and outputs a control signal according to the driven signal so as to clamp the output signal via the audio amplifier.
