Running-in period
The drivers used in the Chorus V loudspeaker are complex mechanical devices and require an run-in period before they deliver their best performance. They must get adapted to the temperature and humidity conditions of their environment. This breaking-in period depends on the encountered conditions and can last several weeks. In order to shorten this period, we advise you to let your loudspeakers operate for about twenty hours. Once the components of the loudspeakers are completely sta­bilized, it is possible to enjoy the real performance of your Chorus V loudspeakers.

Specifications The aluminum/magnesium alloy TNV inverted dome tweeter
tweeter of the Chorus V benefits from the inverted dome technology, which is exclusive to Focal. It allows optimal energy transfer and wide dispersion. The aluminum /magnesium alloy making up of the dome guarantees exceptional performances in terms of stiffness and damping thus ensuring a subtle blend of softness and dynamics.

INSTALLATION
Connections
The Chorus input sockets ensure reliable multipurpose connections for stripped cables as well as for plugs. The “banana” terminals are obstructed in order to comply with electrical standards currently in force in several countries. Make sure not to remove the plastic safety lids. It is imperative to respect the connector polarity of both the loudspeaker and amplifier. The positive terminal “+” must be connected to the corresponding (matching) amplifier’s terminal and the negative terminal “-“ to the negative terminal (fig. A). Stereo image, soundstaging and bass perception would be seriously compromised if these conditions were not respected.
Magnetic disturbance
In home theater systems, the magnetic radiation of the loudspeakers must be taken into consideration. With the exception of the center speakers which are fully magnetically shielded, all other Chorus V loudspeakers generate a magnetic leak that can interfere with household appliances, some of which are sensitive to this phenomenon. It is strongly advised not to place front loudspeakers closer than 50cm to your TV screen. Frame geometry as well as colours can be severely distorted by a magnetic field if the loudspeaker is placed to close to the TV. In case of problems, some TV screens (or computer monitor) feature a degauss control, but not systematically (fig. B).
Positioning
The Chorus V loudspeakers have been engineered to deliver the most faithful sound reproduction, whether they are used for music or home cinema. In order to enhance their performance, to guarantee a high quality of listening, sound image and tone balance, it is important to note the following basic rules.
The listening area must be located at the summit of an equilateral triangle whose two other points
of insertion are determined by the position of each speaker. Nevertheless it is possible to modify these distances to find an ideal compromise according to the particular disposition of the room (fig. C). Each loudspeaker must be placed at the same height and on the same floor plan. The tweeter should be at the same height as the listener’s ear, when the listener is in their usual listening area (fig. D).
Avoid placing the loudspeakers too close to the room’s corners or walls. This will induce some
unwanted room resonance and artificially increase bass response. On the contrary, if the bass level proves to be insufficient, it is possible to move the speakers closer to the walls to adjust the bass level (fig. E).
Optimization
To please the perfectionists, we shall give an optimum positioning formula : if A is the distance from the boomer centre to the closest wall (floor or wall), B the intermediate distance and
C the longest distance (A<B<C), the
2
relation B position of the speakers.
• Example 1:
The boomer centre is 60cm (24”) from the floor (B=60cm) (mini speaker on a foot), standing 50cm (20”) from the back wall (A=50cm), the side wall will be ideally 72cm (28”)
(C=B
=AC determines the ideal
2
⁄A=72cm) (fig. F).
User instructions
The sound rendition of the Chorus loudspeaker depends strongly upon the listening room’s acoustics, the place of the loudspeakers and the listening area. These factors can be modified in order to correct or enhance a desired effect.
the loudspeakers closer to each other. Harsh or aggressive sound means that your listening room is probably too reflective. Try to use any absorbing materials (such as tapestries, sofa, wall coverings, curtains…) combined with reflective materials to absorb or diffuse resonances.
Should the sound be “flat” or muffled, there are too many
absorbing materials in the listening room. The sound appears to be closed-in, with a narrow stereophonic image. Try to find a better compromise between absorbing and reflective materials within your listening room. Generally the wall to the rear of the speakers should be made up of reflective materials so that the sound image exhibits satisfying volume and width. On the contrary the wall on the rear of the listener should be absorbing in order to avoid reflections damaging the perception of the stereo soundstage. These reflections may limit the impression of depth of the sound image. Furniture, such as bookshelves should be ideally placed along the side walls in order to diffuse sound waves and to prevent some frequencies from being amplified, especially in vocal range (it removes “flutter echo”).

HOME THEATER
Choice of speakers
The Chorus loudspeakers have been engineered to work with stereo systems as well as with home theater systems. If you already own a pair of stereo Chorus V loudspeakers and wish to purchase a complete home theater system, it is of the utmost importance that you use the central and effect loudspeakers of the same product line : Chorus V. It is the sole possible condition to bring to your system a perfect tonal homogeneity and a realistic and coherent reproduction of tri-dimensional effects within the listening room.
Central channel placement
Central channel speakers should be placed close to the TV-screen to obtain a proper placement and a realistic reproduction of the dialog. They could be placed below or above the TV-screen if your TV-unit permits (fig. F). If a standart projection screen is used, the central channel speaker must be placed under the screen. If an acoustically transparent projection screen is used, the central channel speaker can be placed behind and at the bottom of the screen (fig. G).
Effect channel speakers‘s place
The soundtrack mix for a film or music encoded in multichannel format is very complex and allows the listener to benefit from a wide range of special sound effects, which require the use of effect channel speakers. In order to obtain a realistic 3D soundstage, the placement of the speakers is decisive, even when confronted with a restrictive disposition of the listening room. For enhanced performances, the following elements should be noted.
Avoid placing the effect speakers too far from the listening area
otherwise the sound perception will be altered. In order to obtain surround effects, with great sound density we advise you to place the speakers against the sidewalls on each side of the listening room (fig. H, I).
Bookshelf mounting (705 V, 706 V, 806 V)

• Place the wall rest on to the wall
and drill. Use only plugs fitting your wall material.
• If the loudspeaker cable is
embedded in the wall, guide it through the wall mounted bracket’s opening as indicated.
• If the loudspeaker cable is fixed
to the wall slide it under the wall mounted bracket as indicated.
• Guide the loudspeaker cable
through the Polyfix plate as indicated.
• Clip the plate on the loudspeaker to
the wall mounted bracket as indicated (fig. K, L).
Accessories
The Chorus 700 V floorstanding loudspeaker systems include four decoupling spikes (cones) and should be screwed, if necessary, into the four metal inserts situated on the base of the loudspeaker. These spikes ensure a better stability for floorstanding speakers, particularly if the floor is not perfectly flat and smooth. The enclosed spikes are adjustable in height. After having adjusted the height of the spikes, don’t forget to lock them with the locknut. The Chorus 800 V include four decoupling spikes (cones). The spikes are adjustable in height with the supplied key. This key can be reserved for future use in a small housing behind the grille after installation and optimization.

User precautions
The TNV tweeter is made up of a relatively soft aluminum/magnesium alloy and has a “shape memory” that enables it to rapidly take its initial shape again after slight impacts. However we advise you not to remove the speaker grille in order to keep the dome protected. If the dome surface is damaged, tweeter performance may be compromised. As the loudspeaker’s covering materials are strong, scratch- and stain-resistant, maintenance is easy and consists only in cleaning the covering with a dry cloth. If the enclosure is stained, we simply recommend the use of a damp cloth. Never use any solvents, detergents, alcohol or corrosive products, scrap­pers or scouring powder to clean the surface of the loudspeaker. Avoid placing the loudspeakers near a heat source.
About amplifiers
Contrary to what one might think, it is not a too powerful amplifier that might damage a loudspeaker, but rather a lack of power. Actually if the output level of the amplifier is too high it will saturate and distort which will irremediably damage the tweeter. The power handling and frequency response of the Chorus loudspeakers is good enough to highlight the qualities or weak points of the amplifiers they are combined with. Let your retailer help you make the right choice, matching your personal taste and budget.
Cable
Don’t underestimate the importance of the cable: make sure you chose the appropriate section and length. Let your retailer advise you.
