IMPORTANT NOTES
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 (amplier outputs) can have a sufciently 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 amplier 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, modications or repairs that are
not expressly described in this manual.
Contact your authorized service centre or qualied 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.
7. Should the loudspeaker emit any strange odours or smoke, remove it from the
line after having immediately switched the amplier 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 specic
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 (i.e. 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.

ENGLISH
9. RCF S.P.A. strongly recommends this product is only installed by professional
qualied 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 specications 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 amplier 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 amplier 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 amplier 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 sufcient electrical insulation. Refer to local regulations, as 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.

DESCRIPTION
BD 5EN is a bidirectional 20 W weatherproof sound projector in
compliance with EN 54-24 standard.
Main features:
-ABS cabinet with steel mesh grilles.
-It can be installed both indoors and outdoors (IP 65 protection
grade).
-Equipped with transformer for 100 V (/ 70 V) constant voltage lines.
-Internal power setting.
-Ceramic screw terminal for connection.
-Internal thermal fuse.
-Colour: white.
WARNING: loudspeaker connections should be only made by qualied and
experienced personnel having the technical know-how or sufcient specic
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
amplier 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.
Connect the 100 (/ 70) V line through the ceramic terminal block.
1. Select the power rate by connecting only one of the four wires (coming
out from the transformer primary winding) to the central screw of the ceramic
terminal strip:
-20 W, red wire
-10 W, blue wire
-5 W, yellow wire
-2.5 W, white wire
The 3 unused wires must be insulated (e.g. with tape).
The black wire is common and is always linked to the transformer primary
winding.
If connecting to a 70 V line, the power will be halved (red: 10 W, blue: 5 W,
yellow: 2.5 W, white: 1.25 W).

-The loudspeaker input voltage (Vd) shall correspond to the amplier output
voltage (Va).
-The sum of nominal power values (Pd x n) of all loudspeakers connected to
the line shall not exceed the amplier power (Pa).
-Make sure all loudspeakers are connected in phase to ensure a correct
sound reproduction.
-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.
