User manual FOCAL PROFILE

[. . . ] Once the components of the loudspeakers are completely stabilized, it is possible to enjoy the real performance of your loudspeakers. Aluminum / magnesium dome with Poron® surround reveals outstanding performances thanks to a more dynamic and softer tweeter. "W" cone (midrange and woofer): technology of "W" composite cone is a Focal patent. "W" means "Verre-Verre", because of the 2 glass leafs affixed to both sides of a structural foam. [. . . ] 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"). Choice of speakers Yours loudspeakers have been engineered to work with stereo systems as well as with home theater systems. If you already own a pair of stereo Profile 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. 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. 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. Place the effect speakers at a suitable height, slightly above the listener's ears (fig. The SR 908 dedicated surround speaker is provided with a wall mounting kit (fig. A / V amplifiers include compensation systems, which allows to set the delay applied on each channel. In certain conditions, the distance between each speaker and the listening area may vary. This system requires the use of one or two central surround channel speakers (depending on the amplifier) which should be placed behind the listening area. If two effect speakers are used simultaneously, make sure that they are not too far from each other (less than one meter; 40 inches) in order to obtain the best results. Magnetic disturbance In home theater systems, the magnetic radiation of the loudspeakers must be taken into consideration. Floor-standing speakers which are fully magnetically shielded, all other 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.
