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.

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.

ENGLISH

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.

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.

CONNECTIONS

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: a70 V coNNectioN (iNstead of 100 V) eNtails that the selected power is halVed.

WARNING

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

ENGLISH

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

CONSTANT VOLTAGE SYSTEMS

Pa > Pd x n

+ Va

–

– Vd = Va + – Vd = Va + – Vd = Va +

The loudspeaker input voltage (Vd) shall correspond to the ampliﬁer output

voltage (Va).

The sum of nominal power values (Pd x n) of all loudspeakers connected to

the line shall not exceed the ampliﬁer power (Pa).

Make sure all loudspeakers are connected in phase to ensure a correct

sound reproduction.

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.

ENGLISH

NOTES ABOUT

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.

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.
