1. If the music is still silent after the above check operation, the microphone has sound, and it should be checked whether the VOD is faulty. You can move the amplifier to a room where the music and microphone are sounded. If there is sound in other rooms, you can check if there is a problem with VOD (computer song). If there is a problem with the VOD settings or output, reset it.
2. Take a wired microphone and insert it into the MIC (microphone) input port of the combined amplifier. Turn on the Ktv audio or professional audio amplifier power supply, turn on the microphone front input control knob and turn it to the 12 o'clock position. Until twelve o'clock. Turn on the microphone switch and call. If the microphone is silent, insert the microphone into the other two microphone input ports in turn. After all the input ports have been tried, the amplifier may be faulty. You can contact the factory technical engineer for consultation. The processing method, in the case of no electronic technical support, should write the fault status of the power amplifier on a small piece of paper and attach the small piece of paper to the power amplifier, and return it to the factory for repair after packaging.
3. If the Ktv audio and professional audio microphones are sound and the music is silent according to the above method, the input of the sound source (VOD) should be checked first. The input cable is intact and properly connected to the power amplifier. If the wire is intact, the connection is correct. However, the music is still silent. Check whether the music input port on the front panel of the amplifier is consistent with the port of the audio input. Re-select the input port to have a music sound (if the cable is output from the VOD and then connected to the "CD" of the amplifier. At the input end, but the VOD port is selected on the front panel of the amplifier, the music is definitely silent.)
