The power failure of the stage sound equipment itself can be divided into three parts:

1. The circuit inside the equipment itself is partially faulty. This our general audio division can not rule out, the need for professional maintenance personnel or equipment suppliers to warranty.

2. There is a problem with the power supply of the equipment. For example, there are some DC power supply equipment to use the transformer, sometimes the transformer will fail; and is the power cord connecting the equipment problems, this rarely happens, but there is really a good power line looks ok is not power, and change a power line fault is eliminated.

3. There is a problem with the connecting device. For example, the socket connected to the equipment, the power timing device and other problems, the probability of this failure is relatively high, especially in the mobile performance to pay more attention to.
