DIGITAL VERTICAL STEERABLE ARRAY RCF's VSA 2950 runs new generation of digital audio technology

摘要

The VSA 2050 column speaker uses the latest DSP technology to match the audio it's delivering with a specific listening area. This makes it the ideal speaker for indoor installations where acoustics are critical - from churches and auditoria, to convention centres and sports centres. The VSA 2050 processes the audio signal sent to each speaker, controlling its vertical acoustic dispersion. This avoids sending acoustic energy to ceilings and empty floors. The VSA uses state-of-the-art transducers which offer the highest possible intelligibility and wider frequency response. The array is powered by 20, 50W, Class D amplifiers driven by a high-capacity power supply. Its powerful DSPs process the audio signal to each of the 20 3.5in speakers. The column has a maximum SPL of 96db (A-weighted at 3Om),al3O-degree horizontal coverage angle, and a vertical coverage angle selectable between 10 and 30 degrees.
