[. . . ] To reduce the risk of electric shock, do not remove the back panel. Plug having one blade wider than the other). This plug will fit onto the power outlet only one way. If you are unable to insert the plug fully into the outlet, try reversing the plug. [. . . ] Corner positions often excite more low-frequency room resonances, making the bass more uneven with frequency. There is no substitute for experiment as all rooms behave differently, so try the subwoofer in a variety of positions before making a final decision. A piece of music with a bass line ascending or descending the musical scale is useful for assessing the smoothness of the bass response. Having a separate subwoofer does enable you to optimise for room resonances independently from siting the satellite speakers for best imaging. If the subwoofer is to be used in a confined space (eg in custom furniture), the space must be ventilated to allow sufficient air to circulate and cool the unit. The spikes pierce through carpet pile, giving a firm support directly to the floor surface without crushing the pile. If the unit is to be placed on a vulnerable surface, such as a wooden floor, either place a protective disc under each spike or fit the four rubber feet in place of the spikes. When fitting either the rubber feet or the spike feet, first screw the lock nuts fully onto the thread and then screw the feet fully onto the threaded inserts in the base of the cabinet. If the unit rocks, loosen the relevant two opposing feet until the support is firm, then re-tighten the lock nuts to the inserts. Check that there are no cables under the carpet that may be damaged by the spike feet. Do not walk the product on the spike feet as this may cause them to become detached from the cabinet and cause damage. Take care not to impale yourself with the spike feet when moving the product. All B&W products are designed to comply with international directives on the Restriction of Hazardous Substances (RoHS) in electrical and electronic equipment and the disposal of Waste Electrical and Electronic Equipment (WEEE). These symbols indicate compliance and that the products must be appropriately recycled or processed in accordance with these directives. Consult your local waste disposal authority for guidance. We recommend that you retain the packaging for future use. Standby: In this position, the amplifier is in permanent standby, and the light glows red. If the subwoofer is to be out of use for an extended period of time, we recommend you isolate it from the power supply, either by using the POWER switch (11) or by removing the plug from the power socket. The subwoofer may be used with any decoder that has a line-level subwoofer output (normally from an RCA Phono socket). Most decoders with integral power amplifiers still output the subwoofer or LowFrequency Effects (LFE) signal at line level. Decoder with one or more subwoofers ­ fig. Separate pre- & power amplifiers: a b One or more subwoofers with output combined into a single mono signal ­ fig. [. . . ] Keep the product away from sources of direct heat such as radiators and warm air vents to avoid the risk of cracking. The wood is treated with an ultra-violet resistant lacquer to minimise changes in colour over time, but a degree of change is to be expected. This effect may be particularly noticeable where the area covered by the grille, or areas kept in shadow, change more slowly than other areas. Colour differences may be rectified by exposing all the veneer surfaces equally and evenly to sunlight until the colour is uniform. [. . . ]
