Ningde Passion Starry Live: Implementing a Professional Festival Sound System
At the massive “Passion Starry Live” Music Festival held in Ningde, Fujian, thousands of music fans gathered under an expansive outdoor sky to witness high-energy performances. To power an event of this magnitude, the production team required a world-class professional festival sound system capable of delivering high-fidelity, high-impact acoustics across the entire festival grounds. Local pro-audio production specialist Maichuang Audio/Visual (迈创影音) rose to the challenge, deploying ZSOUND’s flagship VCX coaxial line array system, paired with VCSUB subwoofers, CP15 stage monitors, and LA110 compact line arrays to deliver an acoustic masterpiece.
Large-scale outdoor music festivals present deep acoustic complexities. An open-air arena has no walls to contain sound, meaning audio engineers must rely strictly on precise speaker patterns to project acoustic energy forward without letting it dissipate or bounce uncontrollably off the massive metal stage trussing. A robust professional festival sound system must achieve high SPL—sound pressure level, the scientific metric of acoustic volume and impact—while maintaining absolute phase coherence, which refers to sound waves from different speaker drivers arriving at the listener’s ears at the exact same millisecond to prevent muddy sound.
Engineering the Main PA: Why VCX Coaxial Technology Matters
As captured during the on-site setup, the engineering crew from Maichuang Audio/Visual flew twin main arrays of ZSOUND VCX coaxial line arrays flanking the massive stage. Coaxial engineering—a advanced design where high-frequency and low-frequency drivers are aligned on a single physical center point—is a game-changer for large-scale tours. It ensures that regardless of where a fan stands in the audience, the vocals, instruments, and high-frequency details emerge from a single virtual source, dramatically reducing acoustic lobing, which is the uneven acoustic coverage and comb filtering common in standard multi-driver cabinets.
The rugged, integrated rigging hardware allowed the crew to set precise splay angles (the physical tilt angle between individual cabinet boxes in the array) to shape the sound’s vertical coverage. This surgical precision ensured the sound projected over the heads of the front row to reach the furthest spectators in the back of the arena with consistent clarity and volume, defying the open-air wind currents.
Managing Massive Low End: The VCSUB professional festival sound system
No modern rock or electronic music festival is complete without earth-shaking bass. However, uncontrolled bass can ruin a concert by spilling backward onto the stage and muddying the artists’ microphone feeds. To prevent this, the engineering team ground-stacked massive stacks of ZSOUND VCSUB subwoofers in a cardioid configuration—a layout where some subwoofers face backward and utilize specialized digital delay processing to cancel out low-frequency sound behind the stage while doubling the bass impact for the crowd.
These subwoofers were lined up neatly on heavy-duty wooden dollies on the concrete floor, firing tight, punchy low-end energy straight into the mosh pit. This controlled low-end worked hand-in-hand with the visual elements, allowing the deep bass drops to sync perfectly with the dynamic outdoor stage lighting setups flashing across the colossal LED video walls on stage, leaving the audience entirely mesmerized.
Stage Precision and Auxiliary Fills: CP15 and LA110
While the VCX and VCSUB systems handled the audience, the performers on stage required flawless monitoring. The crew deployed ZSOUND CP15 coaxial stage monitors on the stage deck. Stage monitors are wedge-shaped speakers pointed directly at the performers so they can hear their own voices and instruments clearly over the stage volume. The CP15’s coaxial setup provides a localized “sweet spot,” giving singers and musicians studio-quality monitor mixes with exceptionally high resistance to microphone feedback.
Additionally, ZSOUND LA110 compact line arrays were deployed as side-fills—the high-power speakers placed at the far left and right edges of the stage to wash the entire stage floor with full-range sound. This complete coverage allowed the performers to move freely across the wide stage without losing their acoustic reference. By combining these advanced systems, the festival proved that a well-designed professional festival sound system can effortlessly bridge the gap between heavy touring demands and pristine sound quality.
