SAFETY PRECAUTIONS
1. All the precautions, in particular the safety ones, must be read with special attention, as
they provide important information.
2.1 - PRIMARY POWER SUPPLY FROM MAINS
-
The mains voltage is sufficiently high to involve a risk of electrocution: never install or
connect this product when its power cord is plugged in.
-
Before powering up, make sure that all the connections have been made correctly and
the voltage of your mains corresponds to the voltage shown on the rating plate on the
unit, if not, please contact your RCF dealer.
-
The metallic parts of the unit are earthed by means of the power cord.
An apparatus with CLASS I construction shall be connected to a mains socket outlet
with a protective earthing connection.
-
Protect the power cord from damage. Make sure it is positioned in a way that it
cannot be stepped on or crushed by objects.
-
To prevent the risk of electric shock, never open this product: there are no parts inside
that the user needs to access.
2.2 - 24 V dc SECONDARY POWER SUPPLY BY BATTERIES
-
The apparatus operating voltage is 24 V dc, therefore it is necessary to connect in
series several batteries having a lower nominal voltage, example: 2 x 12 V.
-
Always use rechargeable batteries, which need to be chosen according to the
maximum possible load.
-
Verify the polarity of batteries is correct.
-
Do NOT short-circuit batteries (i.e. connecting the 2 opposite poles together with
metallic wires).
-
Throw empty batteries away according to your country laws about ecology and
environment protection.
3. Make sure that no objects or liquids can get into this product, as this may cause a short
circuit.

ENGLISH
5. If this product is not used for a long period, disconnect its power cord and / or batteries.
6. If this product begins emitting any strange smell or smoke, switch it off
immediately and disconnect its power cord.
7. Do not connect this product to any equipment or accessories not foreseen.
For suspended installation, only use the dedicated anchoring points and do not try to hang
this product by using elements that are unsuitable or not specific for this purpose.
Also check the suitability of the support surface to which the product is anchored (wall,
ceiling, structure, etc.), and the components used for attachment (screw anchors, screws,
brackets not supplied by RCF etc.), which must guarantee the security of the system /
installation over time, also considering, for example, the mechanical vibrations normally
generated by transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless
this possibility is specified in the user manual.
8. RCF S.p.A. strongly recommends this product is only installed by professional
qualified installers (or specialised firms) who can ensure correct installation
and certify it according to the regulations in force.
The entire audio system must comply with the current standards and
regulations regarding electrical systems.
9. Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are
recommended by the manufacturer. The equipment / support / trolley assembly must be
moved with extreme caution.
Sudden stops, excessive pushing force and uneven floors may cause the assembly to
overturn.
10. Mechanical and electrical factors need to be considered when installing a professional
audio system (in addition to those which are strictly acoustic, such as sound pressure,
angles of coverage, frequency response, etc.).
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure
level that leads to hearing loss is different from person to person and depends on the
duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic
pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore
necessary to wear ear plugs or protective earphones.
See the manual technical specifications to know the maximum sound pressure level.
12. Situate this product far from any heat sources and always ensure adequate air
circulation around it.
13. Do not overload this product for a long time.
14. Never force the control elements (keys, knobs, etc. ).
15. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the
external parts of this product.
Use a dry cloth.
NOTES ABOUT AUDIO SIGNAL CABLES
To prevent the occurrence of noise on microphone / line signal cables, use screened cables
only and avoid putting them close to:
-
Equipment that produces high-intensity electromagnetic fields.
-Mains cables.
-Loudspeaker lines.

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 (50 W each, with high capacity power supply) for the VSA 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.

ENGLISH
Each speaker has 2 audio inputs, of which one has priority.
VSA speakers can be installed very close to the wall (to be unobtrusive) thanks to their compact
sizes, slim shapes and their (included) wall mounting accessories.
AC VSA S-BR optional accessory: each kit includes a pair of swivel brackets for a single VSA
speaker wall mounting, allowing a horizontal angle pointing up to 60°.
Connections are separated: AC and DC power supply at one end, audio signals and interfaces
on the other. The electrical connections are clearly labelled and made through screw terminals
and other suitable and easy-to-wire connectors.
VSA series (standard version) is intended for indoor sound systems only.
INSTALLATION
The speaker shall be wall-mounted through the two included brackets (picture 1).

Minimum installation height: the speaker bottom shall be at least 1 m from
the floor (suggested height: from 1.5 to 3 m).
T he wood package lid can also be used as drilling TemplaTe picTure ( 2)!
Each bracket shall be fixed to the wall by 4
dowels for 5 mm screws (passing through the 4
holes, see picture 3 – A).
If put to recessed pipelines, the power cables
(230-115 V ac and, separately, 24 V dc) can
pass through the bracket and the loudspeaker
holes (picture 3 – B).
Put the speaker on the bracket hooks and fix
it with the security screws (picture 3 – C),
which prevent the speaker might accidentally
slip off and fall.

Finally, click either STORE SEND (send and store) or all EQ settings (without storing) to
the VSA speaker.
GAIN
Gain setting (dB) of all the audio range (0 = flat).
DELAY
Delay line setting.
If the sound system is made of two or more speaker lines, it is advisable to delay the sound
from the second line onwards (setting a delay time directly proportional to the distance
from the first speaker line), in order to reduce the perception of echo (due to the different
reception times of sounds coming from speakers that are distant one another), give a
correct sense of depth to listeners and improve the speech intelligibility.
You can set the distance in meters (graphically or analytically) or the time in milliseconds
(by entering the numeric value only).

schiacciato da oggetti, al fine di salvaguardarne la perfetta integrità.
-
Per evitare il rischio di shock elettrici, non aprire mai l’apparecchio: all’interno non vi
sono parti che possono essere utilizzate dall’utente.
2.2 - ALIMENTAZIONE SECONDARIA 24 V c. c. TRAMITE BATTERIE
-
L’apparecchio funziona con tensione 24 V in corrente continua (pertanto, occorre
collegare in serie più batterie aventi una tensione nominale inferiore, es. 2 x 12 V).
-
Utilizzare sempre batterie ricaricabili, opportunamente scelte in funzione del massimo
carico possibile.
-
Verificare che sia rispettata la polarità delle batterie.
-Non cortocircuitare le batterie (ad esempio collegando i 2 poli opposti con un filo di
metallo).
-Smaltire le batterie esaurite facendo riferimento alle norme di legge vigenti (nel paese
di utilizzo) in materia di ecologia e protezione dell’ambiente.
3. Impedire che oggetti o liquidi entrino all’interno del prodotto, perché potrebbero causare
un corto circuito. L’apparecchio non deve essere esposto a stillicidio o a spruzzi d’acqua;
nessuna sorgente di fiamma nuda (es. candele accese) e nessun oggetto pieno di liquido
(es. vasi) deve essere posto sull’apparecchio.
4. Non eseguire sul prodotto interventi / modifiche / riparazioni se non quelle espressamente
descritte sul manuale istruzioni. Contattare centri di assistenza autorizzati o personale
altamente qualificato quando:
-l’apparecchio non funziona (o funziona in modo anomalo);
-il cavo di alimentazione ha subito gravi danni;
-oggetti o liquidi sono entrati nell’apparecchio;

previsti allo scopo.
Verificare inoltre l’idoneità del supporto (parete, soffitto, struttura ecc., al quale è ancorato
il prodotto) e dei componenti utilizzati per il fissaggio (tasselli, viti, staffe non fornite da
RCF ecc.) che devono garantire la sicurezza dell’impianto / installazione nel tempo, anche
considerando, ad esempio, vibrazioni meccaniche normalmente generate da un trasduttore.
Per evitare il pericolo di cadute, non sovrapporre fra loro più unità di questo prodotto,
quando questa possibilità non è espressamente contemplata dal manuale istruzioni.
8. La RCF S.p.A. raccomanda vivamente che l’installazione di questo prodotto
sia eseguita solamente da installatori professionali qualificati (oppure da ditte
specializzate) in grado di farla correttamente e certificarla in accordo con le
normative vigenti.
Tutto il sistema audio dovrà essere in conformità con le norme e le leggi
vigenti in materia di impianti elettrici.
9. Sostegni e Carrelli
Se previsto, il prodotto va utilizzato solo su carrelli o sostegni consigliati dal produttore.
L’insieme apparecchio-sostegno / carrello va mosso con estrema cura. Arresti improvvisi,
spinte eccessive e superfici irregolari o inclinate possono provocare il ribaltamento
dell’assieme.
10. Quando si installa un sistema audio professionale, si devono considerare anche i fattori
meccanici ed elettrici (oltre a quelli prettamente acustici, come la pressione sonora, gli
angoli di copertura, la risposta in frequenza, ecc.).
11. Perdita dell’udito
L’esposizione ad elevati livelli sonori può provocare la perdita permanente dell’udito. Il
livello di pressione acustica pericolosa per l’udito varia sensibilmente da persona a persona
e dipende dalla durata dell’esposizione. Per evitare un’esposizione potenzialmente
pericolosa ad elevati livelli di pressione acustica, è necessario che chiunque sia sottoposto
a tali livelli utilizzi delle adeguate protezioni; quando si fa funzionare un trasduttore in
grado di produrre elevati livelli sonori è necessario indossare dei tappi per orecchie o delle
cuffie protettive.
Consultare i dati tecnici contenuti nei manuali istruzioni per conoscere le massime pressioni
sonore che i diffusori acustici sono in grado di produrre.
12. Collocare il prodotto lontano da fonti di calore e garantire la circolazione dell’aria
intorno.
13. Non sovraccaricare questo prodotto per lunghi periodi.
14. Non forzare mai gli organi di comando (tasti, manopole ecc.).
15. Non usare solventi, alcool, benzina o altre sostanze volatili per la pulitura delle parti
esterne dell’unità; usare un panno asciutto.
NOTA SUI CAVI PER SEGNALI AUDIO
Per evitare fenomeni di rumorosità indotta sui cavi che trasportano segnali dai microfoni o
di linea (per esempio 0dB), usare solo cavi schermati ed evitare di posarli nelle vicinanze di:
-apparecchiature che producono campi elettromagnetici di forte intensità;
-cavi della rete elettrica;
-linee altoparlanti.

RCF S.P.A. VI RINGRAZIA PER L’ACQUISTO DI QUESTO PRODOTTO, REALIZZATO
IN MODO DA GARANTIRNE L’AFFIDABILITÀ E PRESTAZIONI ELEVATE.
DESCRIZIONE
La serie di diffusori a colonna multiamplificati (“vertical steerable arrays”) rappresenta una VSA
delle più recenti applicazioni RCF in termini di tecnologia audio digitale.
I 3 modelli disponibili hanno caratteristiche simili, tranne:
- VSA 2050 è il modello di punta avente 20 amplificatori e 20 altoparlanti RCF a gamma
estesa da 3,5”; la sua dispersione verticale è controllata fino a 10° da 150 Hz in su;
- VSA 1250 include 12 amplificatori e 12 altoparlanti RCF a gamma estesa da 3,5”;
la sua dispersione verticale è controllata fino a 10° da 300 Hz in su;
- VSA 850 include 8 amplificatori e 8 altoparlanti RCF a gamma estesa da 3,5”;
la sua dispersione verticale è controllata fino a 10° da 500 Hz in su.
Il processore digitale interno elabora il segnale audio inviato ad ogni singolo altoparlante per
controllare la dispersione verticale complessiva.
I diffusori della serie VSA sono l'ideale per installazioni fisse all’interno in ambienti acusticamente
critici e/o in luoghi dove vi sono particolari vincoli architettonici, come ad esempio: luoghi di
culto, sale d’attesa di stazioni ed aeroporti, metropolitane, auditorium, sale congressuali, palazzi
dello sport, nella gallerie all’interno di centri commerciali, ecc. .
A differenza delle colonne sonore di tipo tradizionale, la calibrazione dei diffusori della serie
VSA si effettua elettronicamente tramite il software RdNet oppure il telecomando VSA SMART
RC per smartphone (da acquistare separatamente e necessario, in quanto include anche il cavo
adattatore USB / RS485 con connettore RJ45 per il collegamento al computer), specificando
l'altezza d'installazione dal pavimento e la distanza massima da coprire o l'area d'ascolto.
Il segnale viene totalmente processato ed amplificato digitalmente grazie anche a 6 FPGA (“Field
Programmable Gate Array”: dispositivi digitali programmabili via software) che gestiscono tutti i
dati all’interno del diffusore. I circuiti elettronici sono modulari in modo da garantire la massima
affidabilità ed una manutenzione semplice.
I diffusori della serie VSA comprendono due diverse ed indipendenti modalità di alimentazione,
una in corrente alternata (230 / 115 V) ed una in corrente continua (24 V), in modo da garantire
piena continuità di servizio. È presente il controllo della tensione, corrente e temperatura in ogni
circuito.
Sono stati previsti e rispettati tutti i requisiti per utilizzare i diffusori della serie VSA in sistemi
audio con funzione di emergenza ed evacuazione.
Una delle caratteristiche più importanti dei diffusori della serie VSA è la semplicità di
configurazione tramite il software RdNet oppure il telecomando VSA SMART RC.
In pochi passi, è possibile orientare e dare forma in maniera virtuale al fascio acustico, anche se
il diffusore è fisicamente installato in posizione verticale.
Tale configurabilità permette di indirizzare il segnale audio esattamente verso l’area d’ascolto,
evitando di disperdere energia acustica verso il soffitto o zone vuote della platea, eliminando
così fastidiosi echi che potrebbero compromettere l’intelligibilità del parlato, soprattutto in
ambienti acusticamente difficili aventi un forte riverbero.
20 amplificatori in “classe D” (50 W ciascuno, con alimentazione ad alta capacità) nel modello
VSA 2050, 12 nel VSA 1250 e 8 nel VSA 850, assicurano il miglior controllo possibile e la miglior
dinamica del suono.
Sono presenti indicatori luminosi (LED) ed un relè per la segnalazione remota di eventuali guasti.
Grazie ad un sofisticato algoritmo sviluppato da RCF, il controllo di “messa a fuoco” del fascio
sonoro non è indispensabile in quanto il miglior risultato possibile è assicurato su tutte le aree
di ascolto.
