6. Precautions for use: 1. After receiving the goods, plug in all the tubes according to the instructions provided by the product;
2. Connect the speaker cable first, then the audio input cable, and finally plug in the power cord;
3. Make sure that the connection is correct before turning on Power switch;
4. Do not turn on the power when the output load is not connected;
5. This machine is a three-phase power socket, which means it is not live, it is best to have a grounding wire to ensure safe use;
6. Non-professionals do not open the case The back cover has high voltage inside to avoid electric shock accidents;
