SAFETY AND OPERATING PRECAUTIONS
IMPORTANT NOTES
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. Speaker lines (amplier outputs) can have a sufciently high voltage (i.e. 100-
70 V) to involve a risk of electrocution: never install or connect this speaker when
the line is alive.
3. Make sure all connections have been made correctly and the speaker input
voltage is suitable for the amplier output.
4. Protect speaker 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, modications or repairs that are
not expressly described in this manual.
Contact your authorized service centre or qualied personnel should any of the
following occur:
- The speaker does not function (or works in an anomalous way).
- Its cable has been damaged.
- Objects or liquids have got into the unit.
- The speaker has been damaged due to heavy impacts or fire.
7. Should the speaker emit any strange odours or smoke, remove it from the line
after having immediately switched the amplier 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 speaker by using elements that are unsuitable or not specic 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
qualied installers (or specialised rms) 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. Mechanical and electrical factors need 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 specications in the user manual to know the maximum sound
pressure the speaker is capable of producing.
12. To ensure a correct sound reproduction, speaker phase is to be respected
(speakers shall be connected respecting the amplier polarity). This is important
when speakers 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, speaker lines should not be laid together with other electric cables
(mains), microphone or line level signal cables connected to amplier inputs.
14. The speaker cable shall have wires with a suitable section (twisted, if
possible, to reduce inductive effects due to surrounding electro-magnetic elds)
and a sufcient electrical insulation. Refer to local regulations since there may be
additional requirements about cable characteristics.
15. Install this speaker far from any heat source.
16. Do not use solvents, alcohol, benzene or other volatile substances for
cleaning the external parts of this product. Use a dry cloth.

1. Remove the two screws on the edge and then separate the front (the
loudspeaker) from its back case, then disconnect the electrical conductors
(TAP and COM) and the safety wire as well.
2. Secure the speaker back case to the desired ceiling (or wall) point with
two dowels (not included) having 6 mm-screws, then insert the 100 / 70 V
speaker line cable and also the earth wire.
3. Connect the 100 V (/ 70 V) line and also the earth wire to the ceramic
screw terminals on the back case internal side.
The IN +/– terminals are used for audio signal input and the OUT +/–
terminals (that are directly connected to the corresponding IN +/– terminals)
can be used as parallel output to link additional speakers.

4. Select the power value among 6 / 3 / 1.5 / 0.75 W
(at 100V) on the loudspeaker transformer by linking
the TAP red wire to the proper terminal.
If the line is 70 V, the power will be halved.
Connect the COM black wire to the (upper)
transformer COM terminal.
Note: the two (lower) traNsformer 8 Ω eCom output
termiNals (seCoNdary wiNdiNg) are direCtly liNked to the
loudspeaker (red aNd blaCk wires).
5. Attach the loudspeaker safety wire to the hook
on the back case internal side.
6. Ret the loudspeaker to its back case, taking care not to cut the wires and
to match the two holes on the edge for the two fastening screws. As soon as
the two speaker parts are reassembled properly, insert and tighten the two
screws.

- The speaker input voltage (Vd) shall correspond to the amplier output
voltage (Va).
- The sum of nominal power values (Pd x n) of all speakers connected to the
line shall not exceed the amplier power (Pa).
- Make sure all speakers 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 speaker power.
- Speaker lines must be kept separated from mains cable, microphone cables
or others, in order to avoid inductive phenomena may cause hum or noises.
- Use speaker cables having twisted wires to reduce hum caused by inductive
effects due to coupling with electromagnetic elds.
