User manual FOCAL CHORUS 706V

[. . . ] Specifications The aluminum/magnesium alloy TNV inverted dome tweeter®: the tweeter of the Chorus V benefits from the inverted dome technology, which is exclusive to Focal. 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. Polyglass® cone woofer and midbass: impregnated paper cones with a fine layer of silica micro-balls for a fully dynamic bass impact, precise and distortion-free. oPC® (optimum phase crossover): phase optimization for a precise , natural and stable soundstage and image. [. . . ] These factors can be modified in order to correct or enhance a desired effect. Should the soundstage be imprecise or not centred, try to move 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. 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”). 03 notice chorus v gb 3 26/09/06, 10:42:35 G H I J 04 K L notice chorus v gb 4 26/09/06, 10:42:35 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. 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. 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. 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. € If the loudspeaker cable is embedded in the wall, guide it through the wall mounted bracket’s opening as indicated.

Optimisation Pour les perfectionnistes, nous donnerons une formule de positionnement optimal : Si A est la distance du centre du boomer à la paroi la plus proche (sol ou mur), B la distance intermédiaire et C la distance la plus grande (A < B < C), la relation B2 = AC définit la position idéale de l’enceinte.
