d&b audiotechnik SL-Series Large-Format Line Array: Redefining Large-Scale Sound Reinforcement
The SL-Series by d&b audiotechnik stands as a testament to the evolving demands of modern sound reinforcement for large-scale venues and events. Designed for high-performance audio delivery, the SL-Series is a significant innovation in the field of large-format line array systems, providing unparalleled sound quality, efficiency, and scalability for concerts, festivals, arenas, and stadiums. With its debut, the SL-Series brought a new era of precision, power, and control to large-format sound systems.
Key Features and Innovations
The d&b audiotechnik SL-Series sets itself apart with several groundbreaking features:
1. Full-Bandwidth Horizontal Directivity Control
A standout characteristic of the SL-Series is its consistent full-bandwidth directivity control. This ensures that even at the lowest frequencies, sound remains controlled and uniform. Horizontal directivity down to 50 Hz across the entire system makes it highly adaptable for diverse environments and audiences, providing clarity and focus in a way that is typically challenging for low-frequency reproduction in large-scale systems.
This feature is particularly important for outdoor events or acoustically challenging indoor venues, as it minimizes unwanted sound reflections and spillover, leading to a more intelligible and immersive listening experience for the audience.
2. GSL and KSL: Power and Precision
The SL-Series is built around two core systems: the GSL and KSL loudspeakers. Each is designed to cater to specific large-scale applications, though both share the same core technologies and innovations.
GSL: This is the largest model in the series and is designed for the most demanding environments, such as stadiums and large outdoor festivals. The GSL system excels in delivering extreme sound pressure levels (SPL) without sacrificing clarity. It uses a combination of two front-facing 14” drivers for low-end reproduction and additional side-firing 10” drivers to maintain low-frequency directivity.
KSL: Slightly more compact than the GSL, the KSL system offers similar performance for slightly smaller venues like arenas and large theaters. It features two front-facing 10” drivers and the same cardioid technology for focused sound reproduction.
Both systems are renowned for their bass extension and control, made possible by a sophisticated cardioid subwoofer setup that limits unwanted low-frequency energy behind the system. This helps to reduce noise pollution, making the SL-Series ideal for outdoor events with strict noise control regulations.
3. Advanced Rigging and Array Processing
In terms of usability, the SL-Series is engineered with user-friendly rigging systems that simplify the setup for touring professionals. The intuitive design allows for quick and safe deployment, even in complex environments.
Complementing the physical setup is the d&b ArrayProcessing technology. This software-based tool optimizes system performance for specific venues by considering the array configuration and acoustics of the environment. With ArrayProcessing, the SL-Series delivers an even SPL distribution across the entire listening area, ensuring that every seat in the venue experiences the same high-quality sound.
4. System Integration and Amplification
At the heart of the SL-Series is the D80 amplifier, which delivers the required power while offering extensive DSP functionality. The amplifier integrates seamlessly with d&b's R1 Remote Control software, giving sound engineers complete control over every aspect of the system, from gain structure to detailed EQ adjustments. The integrated networked control also allows for real-time system monitoring and optimization, a vital tool in large-format events where precision is key.
The SL-Series also supports Dante audio networking, allowing for easy integration with existing digital audio infrastructure and providing additional flexibility for routing and managing large-scale productions.
5. Sustainability and Noise Control
As sound regulations tighten worldwide, particularly in urban environments, the SL-Series addresses these concerns with its controlled directivity and cardioid subwoofer arrangements. These features not only enhance the listening experience but also help event organizers stay compliant with noise regulations by minimizing sound leakage into surrounding areas.
Moreover, the design and material choices in the SL-Series reflect d&b’s commitment to sustainability. The components are built for durability, ensuring that these systems can withstand the rigors of constant use while being energy-efficient, reducing their environmental impact.
Performance in Action: Real-World Applications
The SL-Series has already proven itself in some of the world’s most prestigious events and venues. Whether it’s a global music tour, a large-scale festival, or a sports event, the system consistently delivers high SPLs with remarkable clarity and directivity control.
One notable deployment was at the Glastonbury Festival, where the SL-Series was used to ensure that the massive outdoor crowd experienced consistent, high-quality sound, while minimizing noise leakage into nearby areas. Similarly, the system has been used for stadium tours by major artists, showcasing its versatility in delivering both powerful and detailed sound across vast spaces.
Conclusion: A New Benchmark for Large-Format Sound Systems
The d&b audiotechnik SL-Series is a game-changer in the world of large-format line array systems. With its full-bandwidth directivity control, advanced rigging, precision audio performance, and user-friendly integration, the SL-Series offers an unmatched solution for large-scale sound reinforcement. It meets the complex demands of modern live sound events while setting a new standard for clarity, power, and control. Whether it’s a concert, festival, or sporting event, the SL-Series delivers an immersive, high-impact audio experience that resonates with audiences and professionals alike.
