2. Keep these instructions.
3. Take the warnings into consideration
4. Follow all the instructions.
5. Do not use this device around
water.
6. Only clean with a dry cloth.
7. Keep the loudspeakers away
from sources of heat, such as
radiators, stoves, heat register or any
other devices which give off heat
(including amplifiers).
8. Only use fixing devices, stands,
tripods, supports or tables

or those supplied with the product.
If using a trolley or cart, pay
particular attention when moving
the equipment to avoid any risk of
damage or injury.
|
9. All maintenance must be carried out by a qualified professional.
Maintenance is necessary if any damage has been caused to the device, damage
due to liquid spilt
on the device or objects inserted into the device, exposure to rain or
humidity, a malfunction or physical damage.
10. Do not use accessories not recommended by the manufacturer to prevent any
risk of damage or
injury.
11. Never insert an object into the vents on the device. It may come into
contact with high-voltage
components or cause a short circuit which may lead to fire or electric shock.
Never get liquid on the device.
12. Never try to repair this device yourself; opening the device may expose
you to high-voltages and
other risks. For any maintenance or repairs, contact a qualified
professional.| 13. When it’s necessary to replace components, make sure the
technician uses the components specified by the manufacturer or ones which
have exactly the same characteristics as the original.
Components which aren’t compliant may cause a fire, an electric shock or other
accidents.
14. After any repairs or an intervention on the device, ask the technician to
test the equipment
in order to check that the product works correctly and is safe.
15. The device must not be mounted to a wall or ceiling unless intended by
the manufacturer.
16. In order to avoid damaging your hearing, do not listen to speakers at
high volumes for extended periods of time.
Listening to speakers at high volumes can cause damage to the user’s ears and
may lead to hearing problems (temporary or permanent deafness,
buzzing in the ears, tinnitus, hyperacusis).
Exposure to excessive volumes (over 85dB) for more than one hour can cause
irreparable damage to your
hearing.

Thank you for purchasing a Focal product. Welcome to our High-Fidelity world. Innovation, tradition, excellence and pleasure are our values; our one and only aim is to bring you a sound that is rich, pure and true. To get the most out of your product, we recommend that you read the instructions in this booklet, then store it in a safe place to refer to in the future.
Handling (fig. A)
The Chora loudspeakers have sharp corners.
Take care not to injure yourself when handling them.
Grilles (fig. B)
The Chora loudspeakers are supplied with grilles to protect the speaker
drivers. They are easy to fit or remove thanks to their magnetic attachment
system.
We advise removing them when you are listening to music to get the best
performance from your loudspeakers.
Connections (fig. C)
Chora connectors provide reliable, multi-purpose contacts for stripped cables (up to 3/16” – 4mm diameter), fork terminals or banana connectors. It is imperative that you respect the polarity of the loudspeakers. The connector marked “+” must be connected to the positive output on the amplifier, and the connector marked “-” must be connected to the negative terminal. Stereo image and bass perception will be seriously compromised if these conditions are not respected. Choose good quality cables with a cross-section appropriate for their length: your dealer will be able to advise you.
Recommendations for use
The way the loudspeakers behave depends on the room’s acoustics, the correct
positioning of the loudspeakers within the room and the listener’s location.
You can tweak each of these elements to correct or improve the desired effect.
The sound is harsh, aggressive: your room’s acoustics are probably too reverberant. Consider using sound-absorbing materials (rugs, sofa, wall coverings, curtains, etc.) and sound-reflecting materials (furniture) to absorb or diffuse resonance.
The sound is “flat”, strangled: there are too many sound-absorbing materials in the room; the sound is soaked up and has no depth. Aim for a better balance between the absorbent and reflective materials within your room.
In general, aim to have a reflective wall behind the loudspeakers so that the sound develops correctly. The wall behind the listening area, meanwhile, will ideally be absorbent to prevent rear reflections from “contaminating” the perception of the stereo image. Furniture can be placed judiciously on the side walls to diffuse the sound waves and therefore ensure certain frequency ranges are not excited, particularly in the midrange (suppression of flutter echoes).
Positioning the Chora Center (fig. D, E)
The central loudspeaker should be placed close to the screen for realistic
dialogue reproduction. It can be placed beneath the television if the TV unit
allows this. If a standard projection screen is used, the central loudspeaker
must be placed below the screen for optimum results. (fig. D) If a micro-
perforated screen is used, it can then be placed behind and towards the lower
half of the screen. If positioning the loudspeaker on a furniture unit, make
sure you stick on the silicone feet before installation. You can also add the
rubber base beneath the loudspeaker, in the space provided, to tilt the
loudspeaker backwards and thereby slightly lift the soundstage. (fig. E)
Positioning of Chora Surround loudspeakers (fig. F)
The complexity of today’s film soundtracks, particularly those mixed in 5.1 or
7.1, allows a very broad diversity of surround effects to be achieved. The
choice of where to position the Surround loudspeakers is therefore a deciding
factor in achieving a realistic three-dimensional space. The aim is to achieve
sounds that are sufficiently diffused and difficult to locate by applying some
basic rules.
Avoid placing the Surround loudspeakers too far back in the listening area, as
the perception will be compromised. Opt for a position on the side walls to
obtain the most enveloping sound effects.
– Sit in your listening position
– Refer to the positioning diagram (fig. F). It gives you the best position
for your 5.1 and 7.1 loudspeakers.
Fixing the Chora Surround to the wall (fig. G, H)
– Stick the feet onto the back of the loudspeaker in the spaces provided.
– Position then fix the wall bracket onto the partition. The height at which
the screws will be fixed corresponds to the height of the tweeter. Screws and
wall plugs are not supplied. Only use wall plugs suitable for the nature of
your partition.
– Connect the cables to the loudspeaker before hanging it on the wall.
– Hold the loudspeaker in front of the wall bracket. Attach the loudspeaker
firmly to the bracket by applying pressure to the top of it.
Break-in period
The speaker drivers used in Chora loudspeakers are complex mechanical
components which require a certain time to adapt to operate at their best and
to become acclimatised to the temperature and humidity of the listening
environment. This break-in period varies depending on the climate and may last
a few weeks. To reduce the break-in period, we recommend operating the
loudspeakers for approximately twenty consecutive hours. Once the
loudspeakers’ characteristics have totally stabilised, you will be able to
enjoy your Chora loudspeakers’ performance to the full.
Special precautions
The only maintenance required for the Chora loudspeakers is dusting with a dry cloth. If your loudspeaker becomes dirty, we recommend simply cleaning it with a damp cloth. Never use solvents, detergents, alcohol-based or corrosive products, scrapers or scourers to clean the surface of a loudspeaker. Keep the loudspeakers away from sources of heat.
Choosing the right amplifier
It is not an excess of amplifier power that can damage your loudspeakers and
speaker drivers but a lack of power. Moreover, if the volume is turned up too
high, the amplifier saturates and generates parasite signals that may damage
the tweeter. The dynamic capacity and definition of Chora loudspeakers are
sufficient to reveal the strengths and weaknesses of whatever amplifier is
connected. Your retailer will be able to help you choose the amplifier best
suited to your tastes and budget.
Conditions of warranty
All Focal loudspeakers are covered by warranty drawn up by the official Focal
distributor in your country. Your distributor can provide all details
concerning the conditions of warranty. Warranty cover extends at least to that
granted by the legal warranty in force in the country where the original
purchase invoice was issued.
