SAFETY PRECAUTIONS
GENERAL SAFETY PRECAUTIONS
1� Protect loudspeaker AC and signal lines from damage� Make sure they are
positioned in a way that they cannot be stepped on or crushed by objects�
2� To prevent the risk of electric shock, never open this product: there are no parts
inside that the user needs to access� Never attempt to carry out any operations,
modifications or repairs that are not expressly described in this manual�
3� If this product begins emitting any strange odours or smoke, in case of an active
speaker immediately switch it off and disconnect the power cable; in case of a
passive speaker switch the amplifier off and remove it from the line�
4� Contact your authorized service centre or qualified personnel if any of the
following occur:
- The device 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�
5� Make sure that no objects or liquids can get into this product, as this may cause
a short circuit� This apparatus shall not be exposed to dripping or splashing� No
objects filled with liquid, such as vases, shall be placed on this apparatus� No
naked sources (such as lighted candles) should be placed on this apparatus�
6� 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 product 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� To prevent the
risk of falling equipment, do not stack multiple units of this product unless this
possibility is specified in the user manual�
7� The company strongly recommends to install this product only by professional
qualified installers (or specialised firms) who can ensure 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�

Helpful and relevant information
about the topic
Information about the use of supports,
trolleys and carts� Reminds to move with
extreme caution and never tilt�
This symbol indicates that this product
should not be disposed with your household
waste, according to the WEEE directive
(2012/19/EU) and your national law�
8� Supports, trolleys and carts: The equipment should be only used on
supports, trolleys and carts, where necessary, that are recommended
by the manufacturer� The equipment / support / trolley / cart assembly
must be moved with extreme caution� Sudden stops, excessive
pushing force and uneven floors may cause the assembly to overturn� Never tilt
the assembly�
9� 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 can produce�
ACTIVE DEVICES: ACTIVE SPEAKERS and AMPLIFIERS
1� The mains voltage is sufficiently high to involve a risk of electrocution; install and
connect this product before plugging it in�
2� Before powering up, make sure that all the connections have been made
correctly and the voltage of your mains corresponds to the voltage shown on the
rating plate on the unit, if not, please contact your dealer�
3� The metallic parts of the unit are earthed through the power cable� An apparatus
with CLASS I construction shall be connected to a mains socket outlet with a
protective earthing connection by a 3-pole power cord�
4� Protect the power cable from damage; make sure it is positioned in a way that it
cannot be stepped on or crushed by objects�
5� If the product is not used for a long period, disconnect the power cable�
6� Ensure that no children have access to the installation materials and components�
7� Before powering up, make sure that all the connections have been made
correctly and the voltage of your mains corresponds to the voltage shown on the
rating plate on the unit� If not, please contact your dealer�
8� Always make sure the power cord and and all plug assemblies are certified
and suitable for the use in the particular countries where the product shall be
installed�
9� Use the mains plug to disconnect the apparatus from the mains�
10� If the device is provided with internal fuse or if it requires operations, contact
your authorized service centre or qualified personnel as defined in the IEC
62368-1 3rd Ed� Interfaces at ES3 level present�
11� If the device is provided with power socket with accessible fuse holder, or
accessible independent fuse holder, disconnect mains cable device before fuse
replacement� The fuse on the AC mains input may be on the neutral, the AC
mains shall be disconnected to de-energize the phase�
PASSIVE DEVICES and ACCESSORIES
1� 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�
2� Make sure all connections have been made correctly and the loudspeaker input
impedance is suitable for the amplifier output�
3� 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�
4� 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�
5� 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�
6� Do NOT connect loudspeaker low impedance (8 - 4 Ω) inputs to 100 / 70 V
constant voltage lines�
