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. Speaker 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 speaker when the line is alive.
3. Make sure all connections have been made correctly and the speaker input voltage is
suitable for the amplier output.
4. Protect speaker 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 speaker does not function (or works in an anomalous way).
-Its cable has been damaged.
-Objects or liquids have got into the unit.
-The speaker has been damaged due to heavy impacts or re.
7. Should the speaker 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 speaker 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 (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.
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.).

SAFETY AND OPERATING PRECAUTIONS

ENGLISH
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 user manual to know the maximum sound pressure
the speaker is capable of producing.
12. To ensure a correct sound reproduction, speaker phase is to be respected (speakers
shall be connected respecting the amplier polarity). This is important when speakers are
installed adjacent one another, for instance, in the same room.
13. To prevent inductive effects from causing hum, noise and a bad system working,
speaker lines should not be laid together with other electric cables (mains), microphone
or line level signal cables connected to amplier inputs.
14. The speaker 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 since there may be additional requirements
about cable characteristics.
15. Install this speaker 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
HD 6045EN is a horn speaker in compliance with EN 54-24 standard.
Main features:
-Fiberglass enclosure.
-Four 50 W drivers (overall power: 200 W).
-It can be connected to a 100 V / 70 V line through a ceramic terminal strip.
-Thermal fuse that prevents damage to the audio line due to heat on the speaker.
-Steel bracket.
HD 6045EN horn loudspeakers can be easily aimed and used in sounds systems having
large spaces, for instance car parks, football stadiums, undergrounds, factories, warehouses,
etc. and also in all environments that need high efciency loudspeakers.
RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH HAS BEEN
DESIGNED TO GUARANTEE RELIABILITY AND HIGH PERFORMANCE.

Speaker 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 are made correctly
and prevent any electrical danger.
To prevent any risk of electric shock, do not connect speakers 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.
Remove its back case (by unscrewing all its screws). Connect the 100 V / 70 V line to the
ceramic terminal strip as shown in the following gures.
The ceramic terminal strip can also be used (if necessary) as parallel output to link the next
speaker.

ENGLISH
Ret the back case, taking care not to cut the wires.
Match holes and fastening screws properly, then insert and tighten the screws.
Fix the speaker with suitable wall plugs having screws / bolts passing through the
(ø 12.5 mm) holes on its mounting bracket.
Aim the horn speaker to the listening area and x its position by tightening the two bolts
of its mounting bracket.

-The speaker input voltage (Vd) shall correspond to the amplier output voltage (Va).
-The sum of nominal power values (Pd x n) of all speakers connected to the line shall
not exceed the amplier power (Pa).
-Make sure all speakers 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 speaker power. In sound systems for emergency purposes (‘Voice
Alarm’ systems), only use re retardant cables (i.e. RCF CV210, CV215 or CV225).
-Speaker lines must be kept separated from mains cable, microphone cables or others,
in order to avoid inductive phenomena may cause hum or noises.
-Use speaker cables having twisted wires to reduce hum caused by inductive effects
due to coupling with electromagnetic elds.
