Resonating throughout the ancient county of Qianwei, with sound quality that safeguards this grand event—The complete German AD AUDIENCE DELIGHT audio system has been successfully installed for the “Running Through the Ancient County, Singing Out Qianwei” star-studded concert.

An open-air stadium hosted a grand performance attended by tens of thousands, featuring an unobstructed, expansive venue, multi-tiered stepped seating, and a lineup of singers spanning diverse styles—all demanding exceptional long-distance coverage, outdoor stability, and compatibility with a wide range of musical genres. On March 27, 2026, at 7:30 p.m., the Qianwei County Cultural and Sports Center Stadium played host to the “Running Through the Ancient County—Singing Out Qianwei” star‑studded concert accompanying the Qianwei Half Marathon. Six powerhouse vocalists—Li Xiaojie, Wang Qiang, Xiao Zeng, Zhuang Xinyan, Tan Yan, and Huang Ying—took turns on stage, delivering a rich tapestry of sounds that ranged from soulful pop and military‑inspired folk ballads to sweet love songs, soaring ethnic melodies, and soothing female vocals.

For this large‑scale outdoor stadium event, the complete AD VT series audio system served as the cornerstone of sonic excellence throughout the evening.

I. Project Overview: A 10,000-seat Comprehensive Performing Arts Facility at the Stadium
This concert will be held at the standard open-air stadium of the Qianwei County Cultural and Sports Center, with seating capacity for over ten thousand spectators. As a cultural and tourism highlight accompanying the Qianwei Half Marathon, it brings together six nationally acclaimed vocalists—Li Xiaojie, Wang Qiang, Xiao Zeng, Zhuang Xinyan, Tan Yan, and Huang Ying—spanning a diverse range of styles, from bold pop and military anthems to sweet ballads, ethnic high‑notes, and soothing folk music.
The stage features a massive, three‑screen synchronized LED visual architecture—comprising large screens on the left and right flanks and a central main screen arranged in a three‑dimensional layout—paired with a double‑deck heavy‑duty lighting truss system and equipped with hundreds of professional beam, wash, and color‑changing stage lights. The venue is divided into multiple tiers of viewing areas: front‑row infield, mid‑section, and distant‑stand sections. Standardized security‑barrier access corridors and a dedicated audio‑lighting control booth have been set up, delivering a fully integrated, one‑stop production package for sound, lighting, and stage design. At the heart of the audio system is a complete AD sound reinforcement setup from Germany, providing end‑to‑end coverage and ensuring reliable sound reinforcement throughout the entire 10,000‑seat stadium event.

II. Core Sound Reinforcement Architecture: A Complete Set of German AD VT-Series Professional Outdoor Performance Loudspeakers
Addressing four major pain points—long‑distance sound coverage in open‑air stadiums, acoustic attenuation, dew and moisture caused by diurnal temperature variations, and phase inconsistencies across multi‑tiered stands—the technical team has engineered an integrated AD immersive sound reinforcement solution. The system eliminates third‑party speaker crossovers throughout the venue, employing unified AD‑original‑equipment drivers and DSP‑driven processing to ensure exceptional tonal consistency and phase coherence across the entire space.
1. Main PA: AD VT-12/3LA, a three-way outdoor flagship line array system
On either side of the stage, multiple VT‑12/3LA large‑format line arrays are suspended at height in layered configurations, serving as the venue’s core main‑sound reinforcement system. Featuring VT‑series‑exclusive optimized waveguide horns, they deliver precise, controllable vertical and horizontal directivity, significantly reducing unwanted reflections from the curved stadium seating walls. Each line array provides stable coverage up to 120 meters, while maintaining a loudness difference of no more than 6 dB between the front rows and the uppermost tier, effectively resolving the common issue of “loud foreground, muffled background” in open‑air venues.
Facing Li Xiaojie’s deep, weathered baritone, Zhuang Xinyan’s delicate, sweet ballads, Huang Ying’s soaring ethnic soprano, and Xiao Zeng’s resonant military‑style voice, the VT‑12/3LA faithfully preserves each singer’s unique character: crystal‑clear highs that are never harsh, warm, full-bodied mids and lows, and multi‑part harmonies that blend seamlessly without masking one another. The cabinet boasts IP44‑rated industrial‑grade water and dust resistance, perfectly suited to springtime night dew and temperature fluctuations. Backed by the manufacturer’s rigorous 300‑hour full‑load unit‑aging test, it delivers stable, undiminished performance through all‑night, high‑intensity shows.
2. Low-Frequency Subwoofer: AD VT-218 Dual 18-inch Cardioid Ultra-Low Frequency Array
On either side of the front of the stage, large‑scale AD VT‑218 dual 18‑inch subwoofers are stacked. Featuring the manufacturer’s proprietary cardioid dispersion pattern, they direct low‑frequency energy precisely into the audience area while suppressing low‑frequency bleed‑back to the stage at the source, significantly reducing the risk of feedback in high‑volume outdoor settings.
Li Xiaojie’s “A Friend’s Drink” delivers a rock‑inspired groove, while Wang Qiang’s “Autumn Won’t Return” features soulful bass lines. The band’s live drum kit pulses with infectious rhythm—all powered by the VT‑218, which produces deep, clean low frequencies that avoid the pitfalls of muddiness or thinness, even in vast stadium settings. During massive sing‑alongs, the atmosphere spreads evenly across every corner of the stands.
3. Layered Delayed Reinforcement System
On the second and third tiers of the stadium, AD’s compact time‑delay reinforcement array has been installed in the far‑end stands, precisely compensating for the time‑of‑arrival differences in long‑distance sound propagation and eliminating audio gaps for spectators at the rear. Along the front edge of the stage, AD full‑range fill speakers have been deployed to address the acoustic dead zones in the first row of the infield and on either side of the stage, ensuring uniform, seamless sound coverage throughout the venue. Whether seated in the front rows of the infield or in the uppermost distant stands, listeners enjoy a consistently balanced and cohesive auditory experience.
4. Stage Monitors: AD SP15 Professional Stage Monitor Speakers
The entire stage is equipped with AD SP15 independent‑zone monitor speakers, giving each lead vocalist—Li Xiaojie, Zhuang Xinyan, Huang Ying, Xiao Zeng, and others—as well as every band member their own dedicated monitoring zone. In the stadium’s vast, open-air setting, where sound levels are exceptionally high, the SP15 delivers crystal‑clear separation of vocals, backing tracks, and instrumental parts, ensuring zero feedback and no background noise throughout the entire performance and enabling all six singers to deliver consistent, reliable performances.
5. Audio Control Core
The venue is equipped with a professional, large‑format digital mixing console, paired with AD’s proprietary DSP‑driven power amplifiers and an integrated stadium‑specific acoustic‑field correction algorithm, enabling real‑time adjustment of delay, phase, and EQ settings for each line‑array group. A fiber‑optic audio network ensures lossless long‑distance transmission of audio signals, while the off‑stage sound engineer precisely balances six distinct vocal tracks with a variety of instrumental parts.

III. Five Core Advantages of German AD Audio in Supporting the Star-Studded Concert at Open-Air Stadiums
1. All-weather outdoor environment compatibility
IP44‑rated waterproof and dustproof enclosure, coupled with a wide‑temperature‑range driver, effortlessly withstands springtime nighttime dew, diurnal temperature swings, and light, humid breezes. Compared to conventional indoor speakers, it delivers 72 hours of continuous, high‑intensity outdoor operation, making it ideally suited for all‑night performances in open‑air stadiums.
2. Low-distortion multi‑voice compatibility
With total harmonic distortion as low as 0.3%, it effortlessly handles Huang Ying’s expansive, ethereal ethnic high notes and Zhuang Xinyan’s delicate, sweet soprano, while faithfully reproducing the rich, weathered baritone of Li Xiaojie and Wang Qiang. It also captures every nuanced vocal nuance—Xiao Zeng’s resonant, military‑inspired delivery and Tan Yan’s soothing, lyrical vibrato—presenting each singer’s unique style with crystal‑clear, well‑defined vocal layers.
3. Heart-shaped ultra-low noise reduction technology
The VT-218 features an ultra‑cardioid polar pattern, significantly reducing low‑frequency feedback in the stage monitor area.
