User manual B&W ASW 2500

[. . . ] Quick stops, excessive force and uneven surfaces may cause the product and cart combination to overturn. 16 Servicing ­ Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage or other hazards. 17 Damage Requiring Service ­ Unplug this product from the wall outlet and refer servicing to qualified personnel under the following conditions: a When the power-supply cord or plug has been damaged. D If the product does not operate normally by following the operating instructions. [. . . ] 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. 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. 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 ensure that the technology is put to maximum effect. the ASWTM2500 has been designed for Home Theatre installations and to augment the bass performance of full-range speakers in 2-channel audio use. Adding the subwoofer to your system not only extends the bass to lower frequencies, it improves the midrange clarity by reducing the low-frequency demands on your existing speakers. Please read through this manual fully before Disconnect all sound system equipment from the power supply until the signal connections have been made and checked. The function of the subwoofer is to receive signals from the amplification chain and, where Necessary for 2-channel audio, split the signal into low bass and higher frequencies and feed the latter back out to the satellite speakers. 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). [. . . ] Normally the phase will be set to 0°, but if the subwoofer is positioned at a distance significantly different from the other speakers, or the power amplifier driving the other speakers happens to invert the signal, the 180° position may be preferable. Listen with the switch in both positions and choose the one that gives the fullest sound. Decoders normally have a calibrated noise signal that can be used to set the relative levels of all the speakers, making the task somewhat more straightforward than for 2-channel audio. However, do not be afraid to alter the settings to your personal preference. [. . . ]
