HTM2 Diamond - Speaker BOWERS & WILKINS - Free user manual and instructions

USER MANUAL HTM2 Diamond BOWERS & WILKINS

Your HTM Diamond speaker is heavy and we strongly suggest that it is unpacked in the room in which it is to be used. It is also a sensible precaution to remove jewellery to negate the risk of scratching the speaker’s surface nish. The table above illustrates the component parts that are packed with the HTM2 Diamond and HTM4 Diamond. In the unlikely event that anything is missing please contact the retailer from whom you purchased the speakers. All grilles attach magnetically. The heavier bass/ midrange grille is packed in a separate compartment to prevent movement in transit. Tweeter diaphragms are very delicate and easily damaged. Any mishandling of the tweeter grille close to the unit may result in the grille being attracted into the diaphragm. For this reason, the tweeter grille is supplied ready tted and we recommend that you leave it in place. Environmental Information All Bowers & Wilkins 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. General Guidelines If using a projection television with an acoustically transparent screen, position your HTM Diamond speaker behind the centre of the screen. Otherwise, position it either directly below the screen on a oor- stand or within a furniture unit, or directly above the screen on a wall shelf. Align the front of the speaker approximately level with the screen. The diagrams above and right illustrate the position of a HTM Diamond centre channel speaker within a multi-channel audio-visual system. If a oor-stand is to be used, we recommend the FS- HTM. It is important for both safety and performance that the oor-stand assembly instructions are followed. If a wall-shelf or furniture unit is used, ensure that it is strong enough securely to support the weight of the speaker. If you have any doubt about the strength of a supporting structure you should seek specialist help. Note: Four adhesive plastic feet are supplied with HTM Diamond speakers for use when one is placed on a shelf or within a furniture unit. Remove the backing from the adhesive feet and apply them to the underside of the speaker.5 ENGLISH

Stray Magnetic Fields The speaker drive units create stray magnetic elds that extend beyond the boundaries of the cabinet. These centre speakers are therefore not suitable for use close to old-fashioned CRT televisions and computer monitors. We also recommend you keep other magnetically sensitive articles (computer discs, audio and video tapes, swipe cards and the like) at least 0.5m from the speaker. Modern plasma, LCD and OLED screens are not affected by magnetic elds and CRT projectors are too far from the speaker to be affected. All connections should be made with the audio equipment switched off. HTM Diamond speaker terminals accept a variety of cable terminations: 4mm banana plugs, 6mm and 8mm (1/4 in and 5/16 in) spades, or bare wires up to 4mm (5/32 in) diameter. 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. If you are using the products in any country where these conditions apply, you should ensure that any banana plugs cannot be used in an unsafe manner by children or other uninformed persons. Ask your dealer for advice when selecting speaker cable. Keep its total impedance below the maximum recommended in the speaker specication and use a low inductance cable to avoid attenuation of high frequencies. There are two pairs of terminals at the back of each speaker that enable bi-wiring (top). For conventional, single wire connection, t the supplied link wires to join the like polarity terminals together. Ensure that the positive terminals on the speaker (marked + and coloured red) are connected to the positive output terminal on the amplier and the negative terminals on the speaker (marked – and coloured black) are always connected to the negative output terminal on the amplier. Incorrect connection will not result in damage but will cause poor audio imaging. Always screw the terminal caps down fully to prevent rattles. Note: Bi-wiring separates the signal paths to each section of the speaker and can improve both stereo imaging and detail resolution. It also enables the use of different types of cable for each frequency band. 0.5m - 1m 0.5m - 1m 0.5m - 1m 0.5m - 1m6 ENGLISH 800 Series Diamond cabinet surfaces will usually only require dusting. We recommend you use the cloth supplied with the product. If you wish to use an aerosol or other cleaner, apply the cleaner onto the cloth, not directly onto the product and test a small area rst, as some cleaning products may damage some of the surfaces. Avoid products that are abrasive, or contain acid, alkali or anti-bacterial agents. Do not use cleaning agents on the drive units. Avoid touching the drive units as damage may result. Whenever Bowers & Wilkins speakers are nished in real wood, the nest veneers are selected and treated with an ultra-violet resistant lacquer to minimise changes in colour over time. Nevertheless, like all natural materials, the veneer will respond to its environment and a degree of colour change is to be expected. Colour differences may be rectied by exposing all the veneer surfaces equally and evenly to sunlight until the colour is uniform. This process can take several days or even weeks, but may be accelerated by careful use of an ultra-violet lamp. Wood veneered surface should also be kept away from direct sources of heat such as radiators and warm air vents in order to minimise the possibility of the wood veneer cracking. Before ne tuning, double check that all the connections in the installation are correct and secure. Moving speakers further from the walls will reduce the general level of bass. Space behind speakers also helps to create an impression of depth. Conversely, moving speakers closer to the walls will increase the level of bass and potentially reduce the impression of depth. If you want to reduce the volume of bass without moving the speakers further from the wall, t the foam plugs or, for less severe bass reduction, the foam rings in the port tubes. Fitting a foam plug or ring in a port tube is illustrated above. If the sound is too harsh, increase the amount of soft furnishing in the room (for example, use heavier curtains), or reduce it if the sound is dull and lifeless. Test for utter echoes by clapping your hands and listening for rapid repetitions. Reduce utter echoes by the use of irregular shaped surfaces such as bookshelves and large pieces of furniture. For the most discerning listening, remove the bass/ midrange grilles by gripping around their edges and gently pulling them away from the cabinet. The performance of your speaker may change subtly during the initial listening period. If it 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 suspension will also loosen up during the rst 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. As a guide, allow up to a week for the temperature effects to stabilise and 15 hours of average use for the mechanical parts to attain their intended design characteristics.
