Turn on the microphone switch to shout. If the microphone is silent, insert the microphone in-line into the other two microphone input ports for testing. If all input ports are still silent after testing, the power amplifier may have a fault. You can contact the technical engineer of the factory by phone to consult the treatment method. Without electronic technical support, you should write down the fault status of the power amplifier on a small piece of paper and stick the small piece of paper on the power amplifier, packed and returned to the factory for maintenance.
