RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCES.
DESCRIPTION
VSA series is made of multi-amplified vertical steerable arrays that represent one of the latest
RCF applications in terms of digital audio technology.
The 3 available models have similar features, but:
- VSA 2050 is the top model and includes 20 amplifiers and 20 full-range 3.5” RCF
transducers, its vertical dispersion is controlled up to 10° from 150 Hz and up.
- VSA 1250 includes 12 amplifiers and 12 full-range 3.5” RCF transducers, its vertical
dispersion is controlled up to 10° from 300 Hz and up.
- VSA 850 includes 8 amplifiers and 8 full-range 3.5” RCF transducers, its vertical
dispersion is controlled up to 10° from 500 Hz and up.
The internal digital signal processor processes the audio signal sent to each single internal
transducer in order to control the overall vertical acoustic dispersion.
VSA series speakers are the ideal for indoor installations, where a critical acoustic environment
can be an issue and a moderate visual impact is required, for instance: houses of worship,
airports, railway stations, auditoriums, congress halls, sport halls, shopping malls, etc. .
Unlike traditional sound columns, VSA speaker calibration is carried out electronically via
either RdNet software or its VSA SMART RC remote control for smartphones (to be purchased
separately and necessary, as it also includes the USB / RS 485 cable adapter with RJ45 connector
for linking to a computer), by specifying the installation height above the floor and the listening
area (or the maximum distance from speakers to audience).
The signal is fully processed and amplified in the digital domain, thanks also to 6 FPGAs (‘Field
Programmable Gate Array’) that manage all the data inside the speaker system.
The circuitry is modular to get maximum reliability and easy servicing.
VSA speakers include 2 independent power supply units, controlled by a microprocessor for
either AC (230 / 115 V) or DC (24 V) operation, to get full back-up facility when the product is
intended for emergency purposes.
Each internal circuit is monitored (voltage, current and temperature).
VSA series speakers meet all requirements needed by sound systems for emergency purposes.
One of the most important feature of the VSA digital arrays is their simple configuration, thanks
to RdNet software or its VSA SMART RC remote control for smartphones.
In a few steps, it is possible to tilt down and shape the acoustic beam in a virtual way, while the
column speaker is installed in a physical vertical position.
This configurability permits to address the audio signal exactly to the listening area, avoiding to
send acoustic energy to ceilings and empty floors, thus not introducing additional bad reflections
that would affect speech intelligibility, mainly in critical environments with high reverberation
time.
20 ‘class D’ amplifiers (50W each, with high capacity power supply) for theVSA 2050 model,12
for VSA 1250 and 8 for VSA 850, assure the best possible control and dynamics.
Each cabinet has four LEDs (AC, DC, FAULT and PRIORITY) and provides dry contacts (of an
internal relay) for remote ‘fault’ indication.
Thanks to a sophisticated algorithm developed by RCF, the focus control is not strictly necessary
as the best possible result is guaranteed overall the covered listening areas.
It is possible to set the acoustical coverage (tilt and beam) according to installation height and
the listening area to be served.
