In recent years, various government schools, companies and organizations are willing to hold various large-scale performances, activities. For many cultural centers and theatres, large-scale stage performances, stage amplification is basic. There are many special conditions and uncertainties in stage amplification, such as the architectural acoustics of halls and venues, the number of spectators, the characteristics of programs and performances, etc., which needs more attention to the sound effect of the scene. AVM products and solutions are outstanding. Software simulation design is used to overcome unfavorable factors brought about by venues and stage structures, to enhance the portability of transportation and installation, and to avoid potential safety hazards in stage construction, ranging from fidelity, power of sound, field distribution, effective sound power coverage of playback systems. The layout, power allocation, load transfer matching, power amplifier and transmission efficiency are not to be worried. Cultural performance amplification is mostly focused on music amplification, and to match the performance of the program, higher sound quality is required, so stage amplification is a complex and special sound system engineering, but also on the Performing Arts re-creation, re-improvement process. It requires not only the original sound, but also the stage.
