RCF VSA 2050 Digitally Steerable Sound Column Speaker

The VSA 2050 is a multi-amplified vertical steerable array that represents one of the latest RCF applications in terms of digital audio technology.

VSA 2050 Digitally Steerable Sound Column Speaker

Thanks to powerful DSPs it processes the audio signal sent to each speaker for controlling its vertical acoustic dispersion to address the audio signal exactly to the listening area, avoiding to send the acoustic energy to ceilings and empty floors, thus not introducing bad reflections that would affect speech intelligibility, mainly in critical environments with high reverberation time.
