SAFETY PRECAUTIONS
Before connecting and using the amplifier, please read this instruction manual carefully and keep it on hand for future reference. The manual
is to be considered an integral part of the product and must accompany the amplifier 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 the product.
WARNING: To prevent the risk of fire or electric shock, never expose this equipment to rain or humidity.
1. All the precautions, in particular the safety ones, must be read with special attention, as they provide important information.
2. The power supply voltage of this equipment is sufficiently high to involve a risk of electrocution; therefore, never install or connect the
product with the power supply switched on.
3. Before powering up the amplifier, make sure that all the connections have been made correctly and that the voltage of your power mains
corresponds to the voltage shown on the rating plate on the unit; if it does not, please contact your RCF dealer.
4. The metallic parts of the unit are earthed by means of the power cable. In the event that the current outlet used for power does not provide
the earth connection, contact a qualified electrician to earth the equipment using the dedicated terminal.
5. To protect the power cable from damage, make sure that it is positioned so that it cannot be stepped on or crushed by objects.
6. To prevent the risk of electric shock, never open the amplifier. There are no parts on the inside that the user needs to access.
7. Make sure that no objects or liquids can get into the amplifier, as this may cause a short circuit.
8. Never attempt to carry out any operations, modifications, or repairs that are not expressly described in this manual. Contact your authorized
service centre or qualified personnel should any of the following occur:
- the amplifier does not function (or functions in an anomalous way);
- the power supply cable has been damaged;
- objects or liquids have got into the unit;
- the amplifier has been subject to heavy impact.
9. When the amplifier is not to be used for long periods of time, switch it off and disconnect the power cable.
10. If the amplifier begins to emit any strange odours or smoke, switch it off immediately and disconnect the power supply cable.
11. Do not connect this product to any equipment or accessories not specified.
For suspended installation, only use the dedicated anchoring points and do not try to hang this product using HANDLES or 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 the transducer.
To prevent the risk of falling equipment, do not stack multiple units of this product unless this possibility is specified in the instruction manual.
12. RCF S.p.A. strongly recommends this product is installed 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.
13. SUPPORTS AND TROLLEYS
The equipment should only be used on trolleys or supports, where necessary, that are recommended by the manufacturer. The
equipment/support/trolley assembly must be moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may
cause the assembly to overturn.
14. 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.).
15. 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.
IMPORTANT NOTES
To prevent the occurrence of noise on the cables that carry microphone signals or line signals (for example, 0 dB), only use screened cables
and avoid running them in the vicinity of:
- equipment that produces high-intensity electromagnetic fields (for example, high power transformers);
- mains cables;
- lines that supply loudspeakers.
