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  art 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.  CF S.p.A. will not  ssume any responsibility for the incorrect installation and / or use of this product.
WARNING: To prevent the risk of fire or electric shock, never expose this loudspeaker to rain or humidity and dust, but the case this has been expressly designed and made  o get a suitable IP protection grade (indicated in the product specifications).
SAFETY 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 V) to involve a risk of electrocution: never install or connect this loudspeaker when the line is alive.

3. Make sure all connections have been made correctly and the loudspeaker input voltage (in a constant voltage system) or its impedance 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 / fire.

7. Should the loudspeaker emit any strange odours or smoke, remove it from the line after having 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 therefore 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 musical 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.

OPERATING PRECAUTIONS
– Install this loudspeaker far from any heat source.
– 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.
– If the speaker is used in particulary cold places, drive it with a low signal for 5-10 minutes before using it at maximum power.
RCF S.p.A. thanks you for purchasing this product, which has been designed to guarantee reliability and high performances.

DESCRIPTION

PL40, PL6X and PL8X are ceiling speakers featuring elegant and innovative design that can be flush-mounted in false ceilings or panels. PL6X incorporate a 160 mm (6”) and PL8X a 200 mm (8”) loudspeakerBoth have a coaxial 25 mm (1”) tweeter placed on a bridge support. PL40 incorporate an 86 mm-3.5” a full range speaker. The speakers are equipped with a line transformer that enables direct connection to constant voltage systems at 70 V or 100 V. The multiple sockets on the transformer make it possible to select the output power from among several values. Installation is quick and easy thanks to a special three-hook system that avoids the need for using screws and pallet or other attachment elements.

IN OUTDOOR USE, AVOID INSTALLING THE SPEAKER IN PLACES EXPOSED TO HARSH WEATHER CONDITIONS.
The speaker is designed for flush-mount installation in false ceilings. Before installing the speaker, make sure that there is sufficient space behind the false ceiling panel to  old  he speaker: with respect to the support surface of the front flange of the speaker, a free space of 90 mm (3.46”) for PL8X and 75 mm (2.87”) for PL6X depth is  ecessary 110 mm (4.33”) for the PL40 speaker.

1. Drill a hole of diameter Ø 224 mm (8.82”) for PL8X and 182 mm (1.17”) for PL6X and 122 mm for PL40 in the false ceiling at the point chosen for installing the speaker.
2. Insert the speaker in the hole as shown in Fig. 1 – point 1 .
3. Screw in the three screws that tighten the three attachment terminals A of the speaker, as shown in Fig. 1 – point 2 until the external flange touch the ceiling.
4. Apply the three adhesive foam felts (supplied) to the metal protection grill (Fig.1 – point 3 ), approximately equidistant from each other.
5. Fit the metal protection grill into the speaker, as shown in Fig.1 – point 4 .

CONNECTIONS

To prevent the risk of electric shock, do not connect the speaker with the amplifier switched on.
Before using the speaker, carefully check that all the connections have been made correctly to make sure there are no accidental short circuits that could cause electrical  sparks. The speaker can be connected to constant voltage audio lines at 70 V or 100
V. Connections are made using the 6-pin input terminal strip on the rear part of the speaker.

1. Locate the input conductors to be used.

2. Connect the BLACK conductor of the speaker to the “negative” conductor (-) of the audio line that leads from the amplifier terminal marked -, 0, or COM.
3. Connect the other speaker conductor located using the legend to the “positive” conductor (+) of the audio line. VERY IMPORTANT: To prevent speaker damage, never use the maximum power at 70 V conductor when the speaker or the amplifier is supplied with 100 V lines.
4. To prevent the risk of electric shock, situate the terminal strip in an inaccessible position (e.g. inside the speaker when it is used with the accessory for surface mount installation). When making the connections, keep the following indications in mind (Fig. 2 “next page”).

– The input voltage selected on the speaker must correspond with the voltage selected on the amplifier.
– The sum of the operating power values of all the speakers connected to theaudio line must not exceed that of the amplifier.
– To ensure correct audio reproduction, the connections should be made “in phase”, where the +/- polarities of the amplifier output correspond with the +/- polarities of the speaker input.
When two speakers reproduce the same frequencies but with phase differences, these frequencies may be annulled. In sound systems, speakers are often situated in adjacent   ositions and the sound waves produced interact with each other. If a speaker is connected incorrectly; i.e. the polarity of the audio line conductors is inverted, the audio   ignals are transmitted with differences in phase and correct reproduction is therefore jeopardized.

Pd = Speaker power
n = Number of speakers
Vd = Speaker input voltage
Va = Amplifier output voltage

INPUT CABLES

For connecting the speaker use cables with an adequate cross-section. The greater the distance between the amplifier and the speaker, the larger the connection cable cross-section should be to limit the voltage loss along the line. To prevent inductive phenomena from giving rise to humming or disturbance that jeopardize the effective operation of the audio system, the speaker cables should not be run together with electrical energy conductors, microphone cables, or low level audio lines (e.g. LINE level). To facilitate the ‘’in phase’’ connection of the speaker, use bipolar cables that have markings to distinguish the polarity (e.g. insulation of different colours, conductors of different colours, ect.). To minimize the inductive effects (hum) due to coupling with surrounding electrical fields, use cables with conductors braided together.
