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.

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 therefore 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 musical 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.

OPERATING PRECAUTIONS

 

-

Install this loudspeaker far from any heat source. 

 

-

Do not overload this product for extended periods of time.

 

-

Never force the control elements (keys, knobs, etc. ).

 

-

Do not use solvents, alcohol, benzene or other volatile substances for 
cleaning the external parts of this product.

 

-

If the speaker is used in particulary cold places, drive it with a low signal for 
5-10 minutes before using it at maximum power.
