The ideal speaker solution for the indoor installations where the critical acoustic environment is an issue and where moderate visual impact is required. The RCF VSA is now available in three models: VSA 2050, VSA 1250 & VSA 850.
VSA allows 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.
The design was to offer voice directivity and control over all the voice range, to give high intelligibility performance with wide frequency response and high dynamics and coherence at distance. RCF engineers have been able to reach this goal thanks to the length of the column, the number and size of the speakers, the choice to use a dedicated amplifier for each loudspeaker and other innovative details.
Tilting and beaming are not to be affected by the steering and the horizontal coverage is very wide and not impaired by discontinuities.
Thanks to the column power, the accurate speaker design and the high efficiency of the digital technology the VSA is able to obtain a very long coverage, up to 30 meters preserving a smooth uniform horizontal coverage as well.
Intelligible audio transmission in critical acoustical environments:
• Transportation halls
• Sports arenas
• Convention centres
• Conference halls
• Houses of worship
THE VSA FAMILY
The VSA 2050, VSA 1250 & VSA 850 is a multi-amplified vertical steerable array that represents one of the latest RCF applications in terms of digital audio technology and is the ideal speaker for indoor installations where the critical acoustic environment is an issue and where moderate visual impact is required.
Thanks to the use of the latest DSP technology, the VSA 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.
State of the art 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 each Class-D technology power amplifiers, which are able to drive the transducers with the optimal headroom. The amplification circuits include several protection systems and controls to ensure safe operation of the speaker.
Through the remote control’s user friendly touch screen interface it is possible to select among three different groups of presets that offer a remarkable easiness in the VSA configuration process.
For two out of three groups of presets the only parameters that the operator has to insert, in fact, are the installation height of the column and the area to cover.
A structure in extruded aluminium has been made to offer a product with very limited architectural impact, lightweight and simple installing operation.
