SAFETY PRECAUTIONS
1. All the precautions, in particular the safety ones, must be read with special attention, as
they provide important information.
2. POWER SUPPLY FROM MAINS
a. The mains voltage is sufficiently high to involve a risk of electrocution; install and con-
nect this product before plugging it in.
b. 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 RCF dealer.
c. 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.
d. Protect the power cable from damage; make sure it is positioned in a way that it can-
not be stepped on or crushed by objects.
e. To prevent the risk of electric shock, never open this product: there are no parts inside
that the user needs to access.
3. 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.
4. 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 product does not function (or functions in an anomalous way).
- The power cable has been damaged.
- Objects or liquids have got in the unit.
- The product has been subject to a heavy impact.
5. If this product is not used for a long period, disconnect the power cable.
6. If this product begins emitting any strange odours or smoke, switch it off immediately
and disconnect the power cable.
7. 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.
8. RCF S.p.A. strongly recommends this product is only installed by profession-
al 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 regula-
tions regarding electrical systems.
9. Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are rec-
ommended 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.

- Always use cables having wires with an adequate cross section considering the cable length and the total loudspeaker power 7
- Do not connect the low impedance input directly to 70 100 v constant voltage lines 7
- English 7
- Loudspeakers line shall be short for long distances it may be necessary to use cables with large cross section wires 7
- Loudspeakers lines must be kept separated from the mains cables microphone cables or others in order to avoid inductive phenomena may cause hum or noises 7
- Notes about low impedance connections 7
- Specification 7
- The total loudspeakers impedance must not be lower than the amplifier output impedance note loudspeakers total impedance equal to the amplifier output one permits to get the maximum deliverable power but a higher value entails less power 7
- The total loudspeakers power shall be adequate for the maximum deliverable power of the amplifier 7
- Use loudspeakers cables with twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic fields 7

- L impedenza totale dei diffusori non deve essere inferiore a quella d uscita dell amplificatore nota l impedenza complessiva dei diffusori uguale a quella d uscita dell amplificatore permette l erogazione della massima potenza mentre un impedenza superiore comporta una riduzione della potenza erogata 13
- La lunghezza delle linee diffusori deve essere ridotta al minimo una lunga distanza può comportare l uso di cavi con sezioni elevate 13
- La somma delle potenze dei diffusori deve essere adeguata alla potenza massima erogabile dall amplificatore 13
- Note sui sistemi con connessione a bassa impedenza 13
- Per evitare che fenomeni induttivi diano luogo a ronzii disturbi e compromettano il funzionamento del sistema i cavi per i diffusori non devono essere canalizzati assieme ai conduttori dell energia elettrica ai cavi microfonici od altre linee 13
- Per minimizzare gli effetti induttivi ronzii dovuti all accoppiamento con campi elettro magnetici circostanti utilizzare cavi con conduttori intrecciati 13
- Utilizzare dei cavi con conduttori aventi una sezione adeguata considerando la loro lunghezza e la potenza complessiva dei diffusori 13
