[. . . ] The correct fuse specification for each voltage range is marked on the product. 24 Safety Check ­ Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating condition. 25 Magnetic Fields ­ the product creates a stray static magnetic field. Do not place any object that may be damaged by this magnetic field (eg cathode ray tube televisions or computer monitors, audio and video tapes and swipe cards) within 0. The appliance may cause distortion of cathode ray tube images beyond this distance. We recommend that you retain the packaging for future use. In addition to this manual, the carton should contain: 1 Subwoofer 1 Accessory pack containing: 4 Rubber feet 4 Spike feet 4 Lock nuts 1 International warranty document Since its foundation in 1966, the continuing philosophy of B&W has been the quest for perfect sound reproduction. Inspired by the company's founder, the late John Bowers, this quest has entailed not only high investment in audio technology and innovation but also an abiding appreciation of music and the demands of film sound to Because the subwoofer produces only lowfrequency sounds, positioning is less critical in some respects compared to full-range speakers. Directional information is much less precise and you have more choice where to place the speakers to good effect. This said, best results are obtained if the subwoofer is placed between the satellite speakers or in the vicinity of one of them. If you use two subwoofers, it is best to put one near each satellite speaker. Placing the subwoofer behind the listeners, even in surround sound installations, generally gives inferior imaging, but may be an acceptable compromise if domestic considerations dictate. As with all speakers, the proximity of room boundaries affects the sound. Bass is generally increased as more surfaces come into close proximity with the speakers. Unlike full-range speakers, however, you can always restore the correct overall system balance by adjusting the volume level of the subwoofer. The more boost you get from the room, the less hard the speaker has to work; but there is a down side. Corner positions often excite more low-frequency room resonances, making the bass more uneven with frequency. Use the following table to select the correct wiring method for your installation: The phasing is correct ­ there should be no positive to negative connections to the satellite speakers. If something is out of phase you may get a fuzzy sound with an imprecise and floating image, a lack of bass or a combination of the two. There are no left to right mix-ups ­ this can result, for example, in the orchestra being the wrong way round or, more disastrously, sounds on your Home Theatre going in the opposite direction to the action on the screen. We recommend that you switch the subwoofer on before any power amplifiers receiving signals from the subwoofer. Similarly, when switching off, switch the subwoofer off last. [. . . ] If this occurs, re-set the subwoofer by turning it off then on again, using the power on/off switch on the amplifier panel. The situation with home theatre is somewhat different from 2-channel audio. the subwoofer (LFE) signal is a separate channel rather than an extension of the signal to the satellite speakers. The LOWPASS filter is switched out, because the decoder provides all the filtering for any speakers set to "small". [. . . ]
