RCF VSA 850 digitaalselt juhitav tulpkõlar
RCF VSA 850 on VSA seeria tulpkõlar, mille uuenduslik tehnoloogia võimaldab kõlari helisignaali digitaalselt suunata. Tulpkõlari kõikide integreeritud elementide helisignaalid on vertikaalselt suunatavad, võimaldades vähendada halva akustikaga ruumides ebavajalikke helipeegeldusi. RCF VSA 850-l on integreeritud heliprotsessor (48kHz 32-bit DSP) ning 8x 3.5" full range kõlarit, pakkudes kvaliteetset heli nii auditooriumites, spordihallides, kirikutes ja teistes sarnastes seadistutes. Heli katvus horisontaalselt kuni 130°. Helisagedus: 130 - 18.000 Hz.
- Värvus: Hall/RAL 9002
Digitally steerable sound column speaker
The VSA 850 is a multi-amplified vertical steerable array that represents one of the latest RCF applications in terms of digital audio technology.
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.
Superb quality, control and reliability
VSA 2050 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 target we aimed at when designing the VSA 2050 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. We’ve 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 2050 is able to obtain a very long coverage, up to 30 meters preserving a smooth uniform horizontal coverage as well.
