RCF VSA-850-II Vertical Steerable Column Array Speaker

RCF VSA 850 II vertical steerable array speaker system

The RCF VSA 850 II vertical steerable array speaker system is designed for high intelligibility speech and background audio distribution in acoustically challenging environments such as transport hubs, auditoriums, houses of worship, and public buildings. It uses advanced digital beam steering technology to precisely control vertical dispersion, directing sound energy toward the listening area while minimizing reflections from ceilings and floors. This improves clarity in spaces with long reverberation times and ensures consistent coverage across distance.

The system integrates eight Class D 50 W amplifiers driving eight 3.5-inch neodymium full-range transducers, all managed by a high-resolution 48 kHz, 32-bit DSP engine. This allows precise control over beam angle, equalization, and system protection parameters. Horizontal coverage is wide at 130 degrees, while vertical steering ranges from 0 to –40 degrees, allowing installers to tailor coverage to architectural requirements.

With RDNet network compatibility, the VSA 850 II can be monitored and controlled remotely, enabling real-time system diagnostics, configuration, and optimization. Its extruded aluminum enclosure ensures durability, thermal stability, and discreet integration into architectural spaces. Multiple operating modes, including easy beam and free beam configuration, allow both simplified setup and expert-level tuning.

Designed for safety-critical applications, it includes EN 60849 monitoring indicators, dual power compatibility with AC and DC backup support, and built-in protection against thermal overload and electrical faults. The RCF VSA 850 II delivers reliable, intelligible audio performance with flexible installation options and intelligent control features for modern professional sound reinforcement systems. Engineered for professional installations, it ensures long-term reliability, efficient system integration, and consistent acoustic performance across demanding architectural and acoustic environments.
