Zusammenfassung:	The present invention relates to audio amplifier and a method for protecting the audio amplifier. The audio amplifier includes a pre-amp circuit, an output stage power amplifier, a temperature detector and a gain adjusting circuit. The pre-amp circuit receives an audio signal for amplifying the audio signal to generate an amplified audio signal. The output stage power amplifier receives the amplified audio signal to drive a load. The temperature detector is used for detecting a temperature of the output stage power amplifier to output a temperature signal. The gain adjusting circuit adjusts amplitude of the amplified audio signal of the pre-amp circuit according to the temperature signal.
