User manual B&W HTM7

[. . . ] 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. Because of the higher stray magnetic field in front of the speakers, we recommend you keep magnetically sensitive articles (computer discs, audio and video tapes, swipe cards and the like) at least 0. Please read this manual fully before unpacking and installing the product. [. . . ] ensure the positive terminal on the speaker (marked + and coloured red) is connected to the positive output terminal of the amplifier and negative (marked ­ and coloured black) to negative. Incorrect connection can result in poor imaging and loss of bass. To bi-wire, remove the links by loosening the terminal caps and use a separate 2-core cable from the amplifier to each pair of terminals. When bi-wiring, incorrect connection can also impair the frequency response. The terminals accept 6mm (1/4-in) spades, bared wire ends or round pins up to 6mm diameter and 4mm banana plugs. When using spades, fit them under the sliding collar. Important safety notice: In certain countries, notably those in Europe, the use of 4mm banana plugs is considered a potential safety hazard, because they may be inserted into the holes of unshuttered mains supply sockets. In order to comply with European CENELEC safety regulations, the 4mm holes in the ends of the terminals are blocked by plastic pins. Do not remove the pins if you are using the product where these conditions apply. Always screw the terminal caps down tightly to optimise the connection and prevent rattles. We suggest you retain the packing for future use. 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. The flat area on top of the television may be smaller than the base of the speaker, so position the feet accordingly. 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 the B&W national distributor in the country of residence who will advise where the equipment can be The speaker drive units are magnetically shielded such that the stray magnetic field outside the boundaries of the cabinet, Ask your dealer for advice when choosing cable. Keep the total impedance below the maximum recommended in specification and use a low inductance cable to avoid attenuation of the highest frequencies. This process can take several days or even weeks, but may be accelerated by careful use of an ultra-violet lamp. For greatest realism in home theatre installations it is important to balance the speakers and adjust the acoustic image to match the size of the screen. [. . . ] Spray aerosols onto the cleaning cloth, not directly onto the product. Test a small area first, as some cleaning products may damage some of the surfaces. The grille fabric may be cleaned with a normal clothes brush whilst the grille is detached from the cabinet. Avoid touching the drive units, especially the tweeter, as damage may result. [. . . ]
