Abstract Since the work of meteorological early warning receiver depends on voice propagation,in the premise of a good network,it is necessary to protect and maintain the normal operation of the power amplifier in order to ensure the accuracy and integrity of the output audio information.Based on the principle of signal,system and the circuit,this paper introduces the working principle of power amplifier module for the meteorological disaster early warning receiver.And the judgment and solution for the relevant faults are also made a detailed analysis.
