How to solve the problem of the amplifier not making any sound?

1. Check the wiring, whether the audio cable connected to the speaker is loose or detached, and whether the audio connection, audio output, and power supply wiring are normal. Do not expose the connector of the connecting wire outside the terminal block.

2. Check if the signal source and audio input switch correspond to the audio input port, and if the input terminal selection is correct.

3. Check if the sound source equipment is outputting normally. If there is a problem with your own sound source or if there is a malfunction in your front-end, simply put, the input of the amplifier itself does not have a signal, so there must be no sound. It is recommended to replace the amplifier or playback equipment and test whether the front-end is normal.

4. Check the volume switch of the amplifier. There is a problem with the settings of the amplifier itself. Some amplifiers have a mute button inside, and if you choose mute, there will be no sound. Therefore, it is recommended that you carefully check the settings of the amplifier to see if you have selected mute or if the volume knob is turned too low.

5. Check if the listening equipment is working properly. If your playback equipment malfunctions, it can also cause your amplifier to not produce sound.

6. Check if the amplifier protection relay is engaged, and listen for any sound of engagement after turning on the amplifier power.

Finally, if none of the above methods can solve the problem, it is recommended to send the amplifier to a professional repair center for inspection and repair.
