1. Half an hour before the opening, turn on all equipment, perform low temperature preheating, and test all equipment and lines at the same time. The low temperature state means that the light is slightly bright.
2. After 15 minutes of preheating, reset all devices to zero, and let the device dissipate heat for no less than 15 minutes.
3. After cooling, you can officially enter the stage of music performance.
4. After the performance is over and the guests leave the venue, the lighting engineer should turn off all performance equipment, allow the equipment to cool for 15 to 20 minutes, and then seal or cover the equipment before the lighting engineer can leave the venue.
