Through the use of the latest DSP technology, the VSA 2050 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 sending 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.
Special transducers have been developed for the VSA, in order to offer the highest possible intelligibility and wider frequency response, according to RCF philosophy.
The powerful DSP circuit is directly connected in digital domain to the 50 W each Class-D technology power amplifiers, which are able to drive the 20 transducers with the optimal headroom. The amplification circuits include several protection systems and controls to ensure safe operation of the speaker.
