[. . . ] 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. Stereo image, soundstaging and bass perception would be seriously compromised if these conditions were not respected. Don’t underestimate the importance of the cable: make sure you chose the appropriate section and length. [. . . ] 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 his usual listening area (fig. Surround and center speakers placement 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. Central channel speakers should be placed close to the TVscreen to obtain a proper placement and a realistic reproduction of the dialog (fig. They could be placed below or above the TV-screen if your TV-unit permits. 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. 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. You can use an in-ceilling surround speakers (fig. Hc) or for back center surround channel for 6. Tweeter adjustment To carry out adjustments, use the switch level located on the front baffle of the speaker as follows (fig. Adjust the tweeter facing the listening area (except IC 105) (fig. 03 notice custom 100 3 6/07/06, 14:08:11 F G H Tweeter level setting “-” Position 04 “0” Position 0dB “+” Position +3dB I -3dB J notice custom 100 4 6/07/06, 14:08:12 Cautions Precautions 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. Running-in period The drivers used in the Custom line loudspeaker are complex mechanical devices and require a run-in period before they deliver their best performance.
