Background

Changjun High School, located in Changsha, Hunan Province, is a century-old institution and one of the “Four Prestigious Schools” in the city. As a model senior high school, it plays an important role in delivering high-quality education and cultivating talent. To further improve teaching efficiency and create a modern learning environment, the school needed a comprehensive PA system that could handle instructional amplification, campus announcements, exam broadcasting, and outdoor activities.

SPON Communications provided a tailored IP PA system solution to meet the school’s diverse needs while ensuring clear sound coverage across different teaching and activity zones.

Playground & Outdoor Spaces

The playground and outdoor spaces presented special challenges due to their proximity to a busy commercial area and the lack of a canopy on the podium. To address these issues, SPON deployed lightweight linear speakers for long-range sound projection, supported by fill speakers to cover uneven areas and maintain balanced sound distribution without disturbing nearby neighborhoods. All outdoor equipment features waterproof and weather-resistant designs to ensure durability in any climate, while a directional antenna system was introduced to enhance wireless microphone stability, allowing effective long-distance use and optimized sound propagation across the entire playground.
