RCF VSA 850 & 1250

The VSA 850 and VSA 1250 are designed to process the audio signal sent to each speaker for controlling its vertical acoustic dispersion to address the audio signal 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 company says.

The DSP circuit is connected in digital domain to the twelve 50 W each Class-D technology power amplifiers, which drive the 8 (for the 850) or 12 (for the 1250) transducers. The amplification circuits include several protection systems and controls.

Through the remote control’s user touch screen interface it is possible to select among three different groups of presets.

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.

The products are made of extruded aluminium.
