With nearly zero defect sound effects, it delivered a benchmark-level answer for large-scale outdoor entertainment sound reinforcement in China.

I. European Acoustic Heritage Over the Past 50 Years | In-depth Analysis of the German AD (AUDIENCE DELIGHT) Professional Audio Brand

The German AD brand, officially known as AUDIENCE DELIGHT, is a globally renowned high-end professional audio brand with a history dating back to 1974. It was founded by Dutch entrepreneur Luis van Rossum and senior audio engineer Frans van Meulebroeck. The brand's headquarters were initially located in Spain. It integrated German precision industrial manufacturing standards with European cutting-edge acoustic research and development technologies. Over the past 50 years, it has undergone numerous iterations and upgrades, becoming a leading audio brand in international performances, theaters, and high-end entertainment fields. 1. Global R&D and Production Layout, with Authoritative Certifications AD has established a complete global industrial system. An independent acoustic laboratory has been set up in Europe, and it has received dual authoritative certifications from AES (International Professional Acoustic Industry). It has long served major music festivals in Europe and the United States, as well as world-class theaters and global artist tour concerts. Its products have been exported to over 100 countries.

In 2009, Guangzhou Huaxin Audio Equipment Co., Ltd. officially obtained the exclusive general agent authorization for AD in the Greater China region, fully responsible for the formal import of AD equipment, local scene adaptation, nationwide project implementation and lifelong after-sales maintenance. 2. The industry's cutting-edge technical barriers and durability performance lead the market. AD breaks the industry standard for common products, first and foremost implementing and strictly adhering to a 300-hour full-load durability aging test for individual units. Ordinary speakers on the market only require 2 hours of aging test, and the gap between the two is huge. All original factory units are equipped with glass fiber composite diaphragms, high-temperature-resistant long-stroke voice coils, and titanium alloy tweeters. The equipment's long-term high-load operation has a 75% reduction in failure rate, perfectly adapting to high-intensity usage scenarios such as concerts and all-day business bars. 
Overview of the core acoustic advantages of the brand: 
✅ Precise waveguide horn technology significantly reduces sound pressure attenuation in large spaces. A single array of lines can achieve the farthest coverage of 120 meters. 
✅ The total frequency band distortion is ≤ 0.3%. It can vividly reproduce human voices with great clarity and transparency, and the rock bass has a rich and full sound. It is suitable for various musical styles. 
✅ Outdoor array with IP44 waterproof and dustproof rating, capable of withstanding complex outdoor conditions such as rain, high temperatures, and temperature variations between day and night; 
✅ Equipped with an exclusive D-class digital power amplifier and an intelligent DSP processor, featuring multiple short-circuit and overheating protection, as well as an internal automatic feedback suppression algorithm; 
✅ Thickened and wear-resistant birch wood box body with anti-corrosion coating. Modular and lightweight design. Efficient and convenient large-scale stage hoisting and disassembly. 3. Four complete product matrices, covering all types of acoustic scenarios in the AD industry. Creating a professional audio product line for all scenarios. This 6・18 concert used the brand's core flagship performance line array series. The four product lines have clear divisions of labor and are suitable for different scene requirements: 
Vt-12/3LA. Line array, vt-218 ultra-low-frequency speaker line array. Professional flagship line array series (for concerts) 
A massive acoustic test for tens of thousands of people at an outdoor venue. The AD flagship line array, a hardcore force, fought in this star-studded concert. This venue was for nearly 10,000 people, with a long depth and a layered seating arrangement. The humidity and temperature differences between day and night could easily cause sound energy loss and color discontinuity. Moreover, the artist's repertoire covered various styles such as ballads, rock, and electronic dance music, which placed extremely high demands on the dynamic range of the audio system, the reproduction of human voices, and the power of low-frequency bursts. A customized complete AD amplification solution was specially designed: multiple Vt-12/3LA line arrays were hung on both sides of the main stage as the core of main amplification, and the vt-218 ultra-low array was used to solidify the low-frequency foundation; additional AD delay supplementary sound arrays were added on the upper tier seating to eliminate listening dead zones, and dedicated SP15 speaker arrays were paired with the front edge of the stage to build a complete closed-loop acoustic architecture. Relying on the original factory's 300-hour durability unit standard, the entire system supports 72-hour uninterrupted stable output. The outdoor model is waterproof and dustproof, capable of coping with variable weather conditions on-site; the full-frequency band low distortion acoustic performance allows the audience from the front row to the topmost seating area to clearly capture the singer's vibrato, instrument details, without any noise, distortion, or volume differences, and immersively reproducing the true essence of the music. Fans on the spot gave positive reviews: "No matter where you sit, the vocals are clear and transparent, the drum beats are powerful but not harsh, and the overall listening experience is always on point!" The same-stage artists and band teachers also highly praised the AD stage reverb system, with clear original sound feedback helping the entire performance to stabilize and perform well. There are 30 + service outlets across 30 + provinces and cities nationwide, and overseas expansion to markets such as Myanmar in Southeast Asia. A cumulative total of over 100,000 global projects have been implemented, and the failure rate of large-scale outdoor performances is as high as 99.8%, with zero faults in delivery. 
IV. Multiple benchmark projects have been successfully implemented, and German AD continues to lead the domestic high-end performance market. The star concert on June 18, 2026, came to a successful conclusion, once again demonstrating the top-notch strength of German AD's flagship line array in large-scale outdoor performance scenarios. German AD, leveraging its nearly 50 years of professional acoustic research and development experience, strict original factory quality control, and complete product lines for all scenarios, combined with Huaxin Audio's genuine traceability supply chain, standardized engineering delivery, and global service network, has become the preferred high-end sound reinforcement brand for domestic cultural tourism concerts, public theaters, high-end commercial entertainment, and government and enterprise venues. In the future, Guangzhou Huaxin Audio will continue to synchronize with the cutting-edge acoustic technology of German AD's European original factory, continuously improve the domestic + Southeast Asia global audio industry ecosystem, and with genuine traceable imported hardware, standardized acoustic engineering system, and full-cycle lifelong maintenance services, will continuously provide one-stop high-end audio solutions for national star tours, cultural and tourism music festivals, sports and cultural public buildings, and high-end commercial spaces, promoting the domestic professional audio industry towards standardization and high-quality development.
