User manual FOCAL ELECTRA BE STAND MOUNTING

[. . . ] Never use any solvents, detergents, alcohol or corrosive products, scrappers or scouring powder to clean the surface of the loudspeaker. Running-in period The drivers used in the 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. [. . . ] Example 2: the boomer centre is 30cm (12") from the floor (column speaker) (A=30cm), 1m (39") from the back wall (C=1m), the clearance with respect to the side walls will be B=AC=54. Stereo image, soundstaging and bass perception would be seriously compromised if these conditions were not respected. User instructions The sound rendition of the 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. 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. Turn off any amplifiers connected to SR 1000 Be during each mode selector operation!1) Set the right and left surround loudspeakers back selector in Bipolar position. Note : in bipolar mode, the loudspeakers work together towards the front and the back of the listening area in order to cover it in a smooth and consistent manner. Note : input is always inoperative when the selector is set in the Bipolar position. Always connect the amplifier to SR 1000 Be center bipolar unit input . Note : the side channel is always connected to input for both left end right loudspeakers and the center channel always on input . That approach permits switching the selector from Bi mode to Twin mode without wiring modification. Note : Twin mode allows back and side surround information to be carried simultaneously to a single surround loudspeaker, dividing it in two parts beaming towards the front and the back of the listening area. Note : surround side channel information will be carried to the front while center channel information will be carried towards the back of the listening area thanks to the two sets of separated connectors. 1) Back center speaker : when a third back center loudspeaker is added to the system, SR 1000 Be side channels are to be set in Bi mode while the surround center channel is to be set in Twin mode. Connect the left back surround channel to input and the right back surround channel to input (fig. [. . . ] Insert the foam bung into the port tube until it is flush with the front surface. 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 loudspeakers is good enough to highlight the qualities or weak points of the amplifiers they are combined with. [. . . ]
