User manual B&W NAUTILUS HTM2

[. . . ] Some have a button specially for this purpose. If not, switch off the set at the mains for 15 minutes and switch on again. Merely putting the set into standby mode is not sufficient. If you still have a problem, try moving the speaker either forwards or backwards a little to get a more favourable juxtaposition, or space the speaker further from the television until the distortion disappears. [. . . ] Should service be required, please follow the following procedure: 1 If the equipment is being used in the country of purchase, you should contact the B&W authorised dealer from whom the equipment was purchased. If the equipment is being used outside the country of purchase, you should contact B&W national distributor in the country of residence who will advise Wood is a natural material and veneers vary between batches. Expect some variation in the finish between all the speakers in a home theatre installation. If using a projection television with an acoustically transparent screen, place the speaker behind the centre of the screen. Otherwise position it directly above or below the screen, whichever is closest to ear level. Align the front of the speaker approximately level with the screen. fix the 4 self-adhesive pads to the base of the speaker. They give a degree of vibration isolation, especially useful if placing the speaker directly on top of a fairly flimsy There is enough clearance to insert a spade connector from the amplifier into the same terminal as the crimped pin. ensure each positive terminal on the speaker (coloured red) is connected to the positive output terminal of the amplifier and negative (coloured black) to negative. Incorrect connection can result in poor imaging and loss of bass. When bi-wiring, do not use the linking cables. Take extra care with the polarity of the connections as incorrect connection can also impair the frequency response through the bass-midrange crossover and, if the links are left in place, may cause damage to the amplifier by shorting its output terminals. Look for when choosing ancillary equipment, but cannot recommend specific items. The standards of such products are improving all the time and your dealer will be able to demonstrate a variety of suitable up-todate products. in the specification we recommend a range of amplifier powers. The higher figure is defined by the power handling capability of the speaker. When calculating the power handling, it is assumed that the amplifier is not run into clipping, which distorts the frequency power spectrum of the signal, and that the signal is normal programme material. Test tones from oscillators and the like are not applicable. The lower figure is the minimum we consider necessary to achieve reasonable listening levels without audible distortion in the smaller room (less than 60 m3 or 2000 cu ft). The higher the power you use, the less likely you are to experience amplifier clipping. You can often tell how good an amplifier is at driving complex speaker loads by looking at its power rating into both 4 and 8 loads. The nearer the ratio is to 2:1 the better, as it indicates a good current capability. [. . . ] The performance of the speaker will change subtly during the initial listening period. If the speaker has been stored in a cold environment, the damping compounds and suspension materials of the drive units will take some time to recover their correct mechanical properties. The drive unit suspensions will also loosen up during the first hours of use. The time taken for the speaker to achieve its intended performance will vary depending on previous storage conditions and how it is used. [. . . ]
