SAFETY AND OPERATING PRECAUTIONS
IMPORTANT NOTES
Before connecting and using this product, please read this instruction manual
carefully and keep it on hand for future reference. This manual is to be
considered an integral part of this product and must accompany it when it
changes ownership as a reference for correct installation and use as well as
for the safety precautions.
RCF S.p.A. will not assume any responsibility for the incorrect installation and
/ or use of this product.
SAFETY AND OPERATING PRECAUTIONS
1. All the precautions, in particular the safety ones, must be read with special
attention, as they provide important information.
2. Loudspeaker lines (amplier outputs) can have a sufciently high voltage
(i.e. 100-70 V) to involve a risk of electrocution: never install or connect this
loudspeaker when the line is alive.
3. Make sure all connections have been made correctly and the loudspeaker
input voltage is suitable for the amplier output.
4. Protect loudspeaker lines from damage. Make sure they are positioned in a
way that they cannot be stepped on or crushed by objects.
5. Make sure that no objects or liquids can get into this product, as this may
cause a short circuit.
6. Never attempt to carry out any operations, modications or repairs that
are not expressly described in this manual.
Contact your authorized service centre or qualied personnel should any of
the following occur:
- The loudspeaker does not function (or works in an anomalous way).
- The cable has been damaged.
- Objects or liquids have got into the unit.
- The loudspeaker has been damaged due to heavy impacts or re.
IMPORTANT NOTES
7. Should the loudspeaker emit any strange odours or smoke, remove it from
the line after having immediately switched the amplier off.
8. 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 loudspeaker by using elements that are unsuitable or not
specic 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 (wall plugs, 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.

9. RCF S.p.A. strongly recommends this product is only installed by
professional qualied installers (or specialised rms) who can ensure a
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.
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
necessary to wear ear plugs or protective earphones.
See the technical specications in the instruction manual for the maximum
sound pressure the loudspeaker is capable of producing.
12. To ensure a correct sound reproduction, loudspeaker phase is to be
respected (loudspeakers are connected respecting the amplier polarity).
This is important when loudspeakers are installed adjacent one another, for
instance, in the same room.
Make sure loudspeaker lines are not shorted before turning the amplier on.
13. To prevent inductive effects from causing hum, noise and a bad system
working, loudspeaker lines should not be laid together with other electric
cables (mains), microphone or line level signal cables connected to amplier
inputs.
14. The loudspeaker cable shall have wires with a suitable section (twisted,
if possible, to reduce inductive effects due to surrounding electro-magnetic
elds) and a sufcient electrical insulation. Refer to local regulations since
there may be additional requirements about cable characteristics.
15. Install this loudspeaker far from any heat source.
16. 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
PERFORMANCE.
CS 6520EN is a 20 W weatherproof sound column loudspeaker that is in
compliance with EN 54-24 standard.
Main features:
- Extruded aluminium housing.
- It can be installed both indoors and outdoors, thanks to its IP 66 protection
grade.
- Equipped with transformer for 100 V / 70 V constant voltage lines.
- Internal power setting.
- Ceramic terminal strips to link both input and output cables.
- Internal thermal fuse.
- Swivel bracket for wall mounting.
- Colour: white.
WARNING: loudspeaker connections should be only made by qualied and
experienced personnel having the technical know-how or sufcient specic
instructions to ensure that connections are made correctly and to prevent any
electrical danger.
To prevent any risk of electric shock, do not connect loudspeakers when the
amplier is switched on. Before turning the system on, check all connections and
make sure there are no accidental short circuits.
The entire sound system shall be designed and installed in compliance with the
current local laws and regulations regarding electrical systems.

Connections with the audio line are made by using the internal ceramic
screw terminal strip (it is necessary to remove the bottom cover by loosening
its three screws). The + / – terminals allow to connect both input and output
cables (to link other loudspeakers in parallel).
1. Set the power by rotating the switch with a screwdriver.

2. Insert cables through the two rear hexagonal cable glands.
3. Connect the positive wire of the 100 / 70 V line to the loudspeaker +
input.
4. Connect the negative wire of the 100 / 70 V line to the loudspeaker –
input.
5. If necessary, connect in the same way the output cable to link other
loudspeakers in parallel.
6. Connect the earth wire (to the input with the green wire).

NOTA: Make sure that the loudspeaker is installed in a stable and secure
way in order to avoid any conditions that may be dangerous for persons or
structures.
Ensure the support surface (the wall) has the necessary mechanical
characteristics to support the loudspeaker weight.
Before installing the loudspeaker, carefully check all components to be used
and make sure there is no damage, deformation, corrosion and/or missing or
damaged parts that could reduce the safety of the installation.
This loudspeaker can be installed both indoors and outdoors.
Sound column positioning needs a preliminary study in order the get the
optimal performance.
In any case, a good result can be indicatively achieved if the distance from
the sound column bottom and the oor should be at least 1.5 metres from
the oor for a seated audience (or 1.7 m for a standing audience). Tilt sound
columns downwards if necessary.

NOTES ABOUT CONSTANT VOLTAGE SYSTEMS
- The loudspeaker input voltage (Vd) shall correspond to the amplier output
voltage (Va).
- The sum of nominal power values (Pd x n) of all loudspeakers connected to
the line shall not exceed the amplier power (Pa).
- Make sure all loudspeakers are connected in phase to ensure a correct
sound reproduction.
AMPLIFIER
Pa > Pd x n Va
Pa = Amplier power
Pd = Speaker power
n = Number of speakers
Vd = Speaker input voltage
Va = Amplier output voltage
- Always use cables having wires with an adequate cross-section, considering
the cable length and the total loudspeaker power.
- Loudspeaker lines must be kept separated from mains cable, microphone
cables or others, in order to avoid inductive phenomena may cause hum
or noises.
- Use loudspeaker cables having twisted wires to reduce hum caused by
inductive effects due to coupling with electromagnetic elds.
