It depends on the number, grade, stage size, whether there are several performances for several days in a row, the difficulty of handling, other special requirements and other specific requirements. If the equipment is mid-range (for example, the speaker is a well-known domestic brand or an ordinary foreign brand), there is no handling difficulty, there are two pairs of speakers, and there are no other special requirements. There are two debugging operators for a small and simple award-giving event (the scale of shopping mall activities) with a small stage (there will be more debugging operators, and generally more personnel must be arranged when debugging is completed), and the cost is about 3,000-5,000 yuan. If the stage is bigger, the grade is higher and the requirements are higher, the cost will increase accordingly. If the requirements are higher, the equipment grade requirements are also higher (such as high-end imported audio or linear array), and the cost may exceed 10,000 or even higher. For example, some special requirements are quoted separately, such as large-scale high-end projection, led full-color screen and high-end imported lighting.
