SAFETY
PRECAUTIONS
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 (amplifier outputs) can have a sufficiently high voltage
(i.e. 100-70 V) to involve a risk of electrocution: never install or connect this
loudspeaker when amplifiers are switched on.
3. Make sure all connections have been made correctly and the loudspeaker
input voltage is suitable for the amplifier 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, 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 loudspeaker does not function (or works in an anomalous way).
-
The cable has been damaged.
-
Objects or liquids have got into the unit.
-
The loudspeaker has been damaged due to heavy impacts or fire.
-
IMPORTANT NOTES
7. Should the loudspeaker emit any strange odours or smoke, remove it from
the line after having immediately switched the amplifier 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
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.

9. RCF S.p.A. strongly recommends this product is only installed by professional
qualified installers (or specialised firms) 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. 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.).
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
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.
12. 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.
13. 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.
ENGLISH
14. The loudspeaker cable shall have wires with a suitable section (twisted,
if possible, to reduce inductive effects due to surrounding electro-magnetic
fields) and a sufficient electrical insulation. Refer to local regulations since
there may be additional requirements about cable characteristics.
15. Install this loudspeaker far from any heat source.
16. Do not use solvents, alcohol, benzene or other volatile substances for
cleaning the external parts of this product.

RCF S.P.A. THANKS YOU FOR PURCHASING THIS PRODUCT, WHICH
HAS BEEN DESIGNED TO GUARANTEE RELIABILITY AND HIGH
PERFORMANCE.
CS 3041 and CS 3082 are sound columns that are ideal for speech
reproduction, with a shape designed to allow corner installation.
The extruded aluminium body and its metal grille are painted in white RAL
9016.
The wall mounting accessories are included.
CS 3041
Four extended range 2” loudspeakers and one 1” tweeter.
Built-in multi-tapped transformer (10 – 15 – 20 W) for 100 V constant
voltage connection.
A 16 ohm input is available on the terminal strip.
CS 3082
Eight extended range 2” loudspeakers and two 1” tweeters.
Built-in multi-tapped transformer (10 – 20 – 30 W) for 100 V constant
voltage connection.
A 8 ohm input is available on the terminal strip.
DESCRIPTION
CS 3041
CS 3082
WARNING: loudspeaker connections should be only made by qualified and
experienced personnel having the technical know-how or sufficient specific
instructions to ensure that connections are made correctly and to prevent any
electrical danger.
To prevent any risk of electric shock, do not connect loudspeakers when the
amplifier is switched on.
Before turning the system on, check all connections and make sure there are
no accidental short circuits.
The entire sound system shall be designed and installed in compliance with
the current local laws and regulations regarding electrical systems.
On the loudspeaker bottom, there are the screw terminals for the 100 V
constant voltage line connection coming from an amplifier. It is possible to
choose among 3 different power values (CS 3041: 10 – 15 – 20 W, CS 3082:
10 – 20 – 30 W).
Note: a 70 V coNNectioN (iNstead of 100 V) eNtails that the selected power is halVed.
CONNECTIONS
WARNING

The fifth screw terminal (red wire) allows the loudspeaker connection to an
amplifier low impedance output (usuallly 4 – 8 Ω).
Remove the loudspeaker bottom cover (by unscrewing the 2 screws) to access its
terminal strip. The cable shall pass through the loudspeaker rear hole.

NOTES ABOUT
Always use cables having wires with an adequate cross-section, considering
-
the cable length and the total loudspeaker power.
Loudspeaker lines must be kept separated from mains cable, microphone
-
cables or others, in order to avoid inductive phenomena may cause hum
or noises.
Use loudspeaker cables having twisted wires to reduce hum caused by
-
inductive effects due to coupling with electromagnetic fields.

LOW IMPEDANCE CONNECTIONS
The total loudspeaker impedance must not be lower than the amplifier
-
output impedance. Note: a loudspeaker total impedance equal to the
amplifier output one permits to get the maximum deliverable power (but an
higher loudspeaker impedance entails less power).
The total impedance of a group of identical loudspeakers linked in parallel is
-
given by their unit value divided by the loudspeaker quantity.
The total loudspeaker power shall be adequate for the maximum deliverable
-
power of the amplifier.
The loudspeaker line shall be as short as possible.

NOTES ABOUT
ENGLISH
INSTALLATION
WARNING: the loudspeaker is to be installed by qualified personnel,
respecting all safety standards.
The loudspeaker must be installed securely, making sure the support structure
(walls / ceilings) has the necessary mechanical characteristics for the
loudspeaker weight, without the risk of a fall that could damage things or
cause an injury.
Use attachment elements suitable for walls / ceilings (e.g. screw anchors for
bricks, screw anchors for concrete, etc.).
Fix the 2 brackets to the wall (suggested loudspeaker bottom height: 1.5 ÷
2.5 metres / 5 ÷ 8 feet).
Connect the loudspeaker (as described in the ‘Connections’ manual section).
Fix the loudspeaker to the 2 brackets by tightening the 2 bolts.
