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. Loudspeaker lines (amplier outputs) can have a sufciently high voltage to involve a
risk of electrocution: never install or connect this loudspeaker when ampliers are switched
on.
3. Make sure all connections have been made correctly and the loudspeaker input
impedance is suitable for the amplier 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, 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 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 re.
7. Should the loudspeaker 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 loudspeaker 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.).
