With the development of science and technology, there are more and more products in the audio industry. If these products are combined, many sockets will have to be installed, which will bring inconvenience to users. The power timing device can effectively press the previous order of start-up before and after, the shutdown is successive and the switches connected by a kind of electrical equipment equipment, avoid some human error operation, completely solve the river village terminal device, such as amplifiers, speakers can cause damage caused by this error switching machine, at the same time can reduce the impact of electrical equipment on the starting current of the transmission line.
Due to its performance characteristics, the system administrator can never open and close with high complexity, cut off the power supply of electrical equipment, is the sound engineering system and television broadcasting, computer network shrinkage system and other essential electrical engineering equipment
