F✦FOREVER "City of Stars" Tour Hangzhou Stop landed at the Hangzhou Olympic Sports Center Stadium ("Big Lotus"). Tens of thousands of spectators converging into a continuous sea of fluorescent stars, the complex venue acoustic structure, the natural sound energy drop between near and far areas, and the echoes generated by tens of thousands of people singing along overlapping with venue reflections became the core challenges that the production team needed to overcome.

To achieve a differential-free listening experience across the entire venue, the rear fill for the entire show uniformly adopted Reyn Audio's RL2 (RAFALE2) line array speakers. By utilizing a precise acoustic layout to smooth out the boundaries of the sound field, every single seat was ensured to have an equivalent texture of musical experience.

The curved dome and large area walls of the "Big Lotus" easily form sound wave reflections, which, when coupled with continuous cheering and shouting from the whole venue, easily generate issues like echo superposition and muddy sound. The RL2 (RAFALE2) line source structure can constrain invalid sound waves from spreading outward, significantly reducing venue reflection noise. Adequate power (reserves) support a whole night of continuous high-intensity performances, with peak volume output free of distortion and cracking. Even when the live vocal wave reached its peak, the lead singer's voice remained clear and prominent, keeping the sound field background clean and transparent.

Seventy units of Reyn Audio's RL2 (RAFALE2) built a multi-layered stereoscopic fill sound network, filling the blank sound field at the distant end of the venue, allowing every spectator immersed in the Qiantang starry sea to immersively receive complete and pure music signals.

For this Hangzhou stop of the F✦FOREVER "City of Stars" tour, aside from Reyn Audio's complete professional sound reinforcement system, the stage visual system was entirely equipped with ACME professional outdoor IP-rated stage lighting. Featuring a multi-dimensional combination of high-power beams, wash lighting, pixel lines, and atmospheric effects, thousands of lights and shadows accurately linked with the pure sound waves, achieving a unity of sound and light to create a stellar universe illusion unique to Hangzhou's "Big Lotus."

Throughout the show, light, shadow, and melody intertwined and merged. Tens of thousands of spectators below waved light sticks, converging into a brilliant starry sea. As familiar melodies rang out, they ushered in a venue-wide sing-along, with cheers and shouts rising one after another. Every audience member was immersed in the unique romantic scene of the "City of Stars." The F✦FOREVER "City of Stars" tour continues its journey without stopping, and more city stops are eagerly anticipated.
