If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. When using an extension power-supply cord or a powersupply cord other than that supplied with the appliance, it should be fitted with the appropriate moulded-on plugs and carry safety approval appropriate to the country of use. 8 Power Cord Protection ­ Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed on or against them, paying particular attention to cords at plugs, convenience receptacles and the point where they exit from the appliance. [. . . ] 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. Unpacking 23 Mains Fuses ­ For continued protection against fire hazard, use fuses only of the correct type and rating. The amplifier is designed to operate with nominal mains supplies in the range 100V to 230V AC, but different types of fuse are used, dependent on the mains voltage. 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. Left and right channel inputs may be combined into a single mono low bass feed to the subwoofer drive unit if required. The subwoofer will input and output line-level signals via the RCA Phono sockets located on the back panel. Use the following table to select the correct wiring method for your installation: Application: Home Theatre 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 Low-Frequency Effects (LFE) signal at line level. 3 Double-check the connections Before auditioning the sound quality of your new installation and fine-tuning it, double-check the connections. All too often, users complain that they cannot get a decent sound however they set the controls, only to discover something has been wrongly connected. Make sure that: · 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. · · The LOW-PASS FILTER switch (5) The EQ (equalisation) switch (4) The optimum settings depend on the other equipment used with the subwoofer. If using more than one subwoofer, ensure the controls on each one are set the same. Use with home theatre decoders The B&W ASW Active Subwoofer is not a THX® licensed component, but may be used with a THX® controller if desired. · · · · · Set the VOLUME control to the half way (12 o'clock) position. Set the EQ switch initially to position A. · Switching on and off We recommend that you switch the subwoofer on before any power amplifiers receiving signals from the subwoofer. The MODE standby/auto/on switch (3) at the top left of the amplifier panel does not isolate the amplifier completely from the power supply. [. . . ] What may seem like small changes in position ­ 15cm (6in) or so ­ can have a profound effect on the sound. Try raising the subwoofer clear of the floor as well as lateral movement. The use of multiple subwoofers can smooth the effects of room resonances, as each subwoofer will tend to excite resonances at different frequencies. If you alter the relative distances from the subwoofer(s) and satellite speakers to the listeners appreciably, reassess the phase switch setting. [. . . ]
