Every square 30 yuan of the stage, the truss 30 yuan is about one meter, and the linear array is 800- 1000 yuan. Generally, four pairs of linear arrays will start (depending on the number of seats in your audience with several groups of linear arrays). The stage is 300-500 yuan, and the subwoofer 1000 yuan. Wireless microphone and peripheral equipment are not expensive, but if you have a wireless microphone, the specific price depends on the brand of the equipment, as well as regional differences and price differences. Personally, I think there are 1 pairs of subwoofers, 4 pairs of linear arrays (if more seats are needed) and 1 pairs of stage listening. You just need to tell each other how big the stage and background are, what kind of stereo to use and how many wireless microphones to prepare. Other peripheral devices (voltage limiter, amplifier, mixer, effector, equalizer, etc.). You don't need to tell them, they will match. As for lighting, it depends on your budget, starting from 2000 to tens of thousands of yuan.
