● The school auditorium is a multifunctional composite venue, undertaking tasks such as meetings, academic exchanges, lectures, debates, artistic performances, and film screenings. Its sound reinforcement system design therefore demands a high degree of comprehensiveness. However, due to its positioning at the school level, the acoustic design of such auditoriums is often overlooked. Our company recognizes the importance of excellent sound quality in an auditorium and therefore places special emphasis on sound system design. An ideal auditorium sound field should have appropriate loudness and comfort, ensuring clear speech, high transparency, articulate enunciation, and full, resonant sentences. Sound image localization must also be precise to facilitate unspoken emotional communication between speakers and the audience. Even during large-scale performances requiring dynamic expression, a high-quality sound field can ensure the complete delivery of the performance's intent.

● In Meeting Mode:
1.This equipment is primarily responsible for speech-centric amplification services, suitable for academic reports and lecture discussions.
2.To ensure professional verbal communication, high speech intelligibility and uniform sound field distribution are required.
3.Appropriate audio output levels and optimized sound transmission efficiency must be ensured.

● In Performance Mode:
To meet the audio requirements of professional stage performances, the sound system must not only comply with the clarity and accuracy standards of speech amplification but also achieve wide and uniform sound field coverage, ensuring balanced frequency response across all ranges. Additionally, it must provide depth and density in sound effects, as well as special effects required for specific performances. Through precise control, the sound design should enhance the visual intent of stage performances, creating a powerful, immersive, and magnificent on-site atmosphere.
