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.
10.
There are numerous 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 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 with a suitable section (twisted, if possible, to reduce
inductive effects due to surrounding electro-magnetic fields) and a sufficient 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.
When connect to its low impedance input, do not overload the loudspeaker with too much
power.
17.
Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external
parts of this product.
