this product.

WARNING: To prevent the risk of ﬁre or electric shock, never expose this loudspeaker to

rain or humidity and also dust.

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 (ampliﬁer outputs) can have a sufﬁciently high voltage to involve

a risk of electrocution: never install or connect this loudspeaker when ampliﬁers are

switched on.

3. Make sure all connections have been made correctly and the loudspeaker input

impedance is suitable for the ampliﬁer 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, modiﬁcations or repairs that are not

expressly described in this manual.

Contact your authorized service centre or qualified 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 are inside the loudspeaker.

-The loudspeaker has been damaged due to heavy impacts or ﬁre.

7. Should the loudspeaker emit any strange odours or smoke, remove it from the line

after having immediately switched the ampliﬁer 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 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.

9. RCF S.p.A. strongly recommends this product is only installed by professional qualiﬁed

installers (or specialised ﬁrms) 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.

IMPORTANT

SAFETY PRECAUTIONS

ENGLISH

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 speciﬁcations 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 ampliﬁer polarity).This is important when

loudspeakers 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,

loudspeaker lines should not be laid together with other electric cables (mains),

microphone or line level signal cables connected to ampliﬁer inputs.

14. The loudspeaker cable shall have wires (twisted, if possible, to reduce inductive

effects due to surrounding electro-magnetic ﬁelds) with a suitable section and a sufﬁcient

electrical insulation. Refer to local regulations since there may be additional requirements

about cable characteristics.

15. Do NOT connect the loudspeaker low impedance (8 Ω) input to 70 / 100 V constant

voltage lines.

16. Install this loudspeaker far from any heat source.

17. Do not overload the loudspeaker with too much power.

18. Do not use solvents, alcohol, benzene or other volatile substances for cleaning the

external parts of this product. Use a dry cloth.
