SAFETY
PRECAUTIONS
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 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 technical specications in the instruction manual for the maximum
sound pressure the loudspeaker is capable of producing.
12. To ensure a correct musical 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.
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 electromagnetic
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 overload this product.
17. Do not use solvents, alcohol, benzene or other volatile substances for
cleaning the external parts of this product. Use a dry cloth.
