The choice of control system is crucial, DMX512 protocol can realize synchronous control of multiple devices, so that the special effects accurately fit the performance nodes. In terms of equipment layout, the audience's perspective, safety distance and wind direction should be considered to ensure the best viewing effect.

Choosing low-smoke and environmentally friendly consumables, equipping emergency stop devices, and setting up safety warning zones are the basic guarantees for every performance. Creativity has no boundaries, special effects have form, only a deep understanding of the characteristics of each piece of equipment, in order to transform them into a medium of emotional expression, so that the stage becomes a bridge connecting the hearts of the audience.
