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

connect 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

cannot 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.

PRECAUTIONS

ENGLISH

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 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.

9. Supports and trolleys.

The equipment should be only 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.

10. There are numerous mechanical and electrical factors to be considered when installing

ENGLISH

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 manual technical specifications to know
the maximum sound pressure level.

IMPORTANT NOTES

To prevent the occurrence of noise on line signal cables, use screened cables only and avoid
putting them close to:

- Equipment that produces high-intensity electromagnetic fields.

- Power cables.

- Loudspeaker lines.

OPERATING PRECAUTIONS

- Place this product far from any heat sources and always ensure an adequate
air circulation around it.

- Do not overload this product for a long 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.

IMPORTANT NOTES

Before connecting and using this product, please read this instruction manual carefully and
keep it on hand for future reference. The 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.

INFORMATIONS

RCF always has the performer’s needs at the forefront of the design in order to create new lines
of speakers with renewed features, improved sound clarity and definition and even lighter weight
systems.
Every detail of the Sub Series has been carefully studied in order to offer musicians and professionals
the perfect tool to amplify their performance, night after night.
High quality materials, precise manufacturing, careful assembly and extensive quality control
procedures complete the groundbreaking design work of the RCF R&D team.
All transducers are precision built taking advantage of RCF’s superior moulding, assembly
technologies and a wealth of professional knowledge and experience dedicated to achieving
extremely high standards.
All the transducers in Sub Series speakers feature high power magnets in order to guarantee the
best performance and power handling.
Sub Series Subwoofers are equipped with a new generation of Digital Amplifiers. The result of this
is very high output, extremely low distortion and an incredible natural sound.
The amplifier features a solid mechanical aluminium structure which not only stabilize the amplifier
during transportation but also assist in the heat dissipation.
The new loudspeaker design looks aggressive whilst retaining perfect ergonomics and is the result
of extensive combined functional and acoustic research.
The Sub Series Subwoofer cabinets are built in birch plywood and are designed to dampen down
vibrations even at maximum volume settings. The reflex porting has been resized to offer a better
efficiency. The cabinets are equipped with ergonomically designed forged aluminium handles with
rubber handgrip. Rugged steel pole mount has been installed in all models.

The SUB 8003-AS II and SUB 905-AS II are high power, high output active subwoofer systems that
set a new standard in professional sound reinforcement.
Each transducer has been specifically designed for the application. The woofer provides large
excursion and very lightweight.
