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.
- The VDE connector and the main switch are disconnection devices from the mains
and shall be easily accessible after the loudspeaker installation (to disconnect the
loudspeaker from the mains).
- 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

ENGLISH
5.If this product is not used for a long period, disconnect its power cable and / or batteries.
6. If this product begins emitting any strange odours or smoke, switch it off immediately
and disconnect the power supply cable.
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.

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 loudspeaker in order to control the overall vertical acoustic dispersion.
VSA series loudspeakers 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 loudspeaker calibration is carried out electronically
via either its remote control or its respective PC software (VSA-RC/USB kit, to be
purchased separately), by specifying the installation height above the floor and the
listening area (or the maximum distance from loudspeakers 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 loudspeaker
system.
The circuitry is modular to get maximum reliability and easy servicing.
VSA loudspeakers 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 meets 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 its dedicated infrared remote control. In a few steps, through the remote
control touch-screen, it is possible to tilt down and shape the acoustic beam in a virtual
way, while the column loudspeaker 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 the 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.
7
ENGLISH
It is possible to set the acoustical coverage (tilt and beam) according to installation
height and the listening area to be served.
Each loudspeaker has 2 audio inputs, of which one has priority.
VSA loudspeakers 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 accessories: each kit includes a pair of swivel brackets for a single
VSA loudspeaker 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 loudspeaker shall be wall-mounted through the two included brackets (picture 1).
To swivel iT wiTh a horizonTal angle up To 60°, iT is necessary To purchase The opTional
AC VSA S-BR
accessory kiT.
Minimum installation height: the loudspeaker bottom shall be at least 1 m
from the floor (suggested height: from 1.5 to 3 m).
The 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 –

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 loudspeaker on the bracket hooks
and fix it with the security screws (picture
3 –

SETTING MODES
The loudspeaker preset can be chosen in three different setting modes:
- “EASY FOCUS”, simple, easy and suitable for all systems, advisable for users and
installers that are not so expert (only two values are necessary: the loudspeaker
installation height and the max. distance to be covered).
- “EASY BEAM”, intermediate level that allows users / installers to specify the listening
area to be covered (by selecting a preset).
- “FREE BEAM”, advanced level (for expert users / installers) that allows the (virtual)
setting of both loudspeaker tilt and beam.
in case of doubT abouT The choice of The seTTing mode, sTarT from The simplesT one:
‘easy focus’ !
EASY FOCUS
This setting mode permits to cover the listening area uniformly from the loudspeaker to
its focus, minimising the sound pressure level beyond that point and reducing the reflections outside the listening area (that is good for reverberant halls).
Only two values are necessary: the loudspeaker installation height H (considering the
loudspeaker bottom) and the maximum distance to be covered F.
H: loudspeaker bottom installation height
(1.5 – 2.0 – 2.5 – 3.0 m)
F: maximum distance to be covered
(10 – 15 – 20 – 30 m)
ha: considered listening area height (1.2 m)
