User manual B&W 704

[. . . ] 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. Please read this manual fully before unpacking and installing the product. It will help you to optimise its performance. [. . . ] 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 ( /4-in) spades, bared wire ends or round pins up to 6mm The speaker drive units create stray magnetic fields that extend beyond the boundaries of the cabinet. We recommend you keep magnetically sensitive articles (television and computer screens, computer discs, audio and video tapes, swipe cards and the like) at least 0. Before fine tuning, make sure that all the connections in the installation are correct and secure. If the level bass is uneven with frequency it is usually due to the excitation of resonance modes in the room. Even small changes in the position of the speakers or the listeners can have a profound effect on how these resonances affect the sound. Try mounting the speakers along a different wall. Even large pieces of furniture can have an effect. Moving the speakers further from the walls will reduce the general level of bass. Space behind the speakers also helps to create an impression of depth. 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 The speakers closer to the walls will increase the level of bass. If you want to reduce the bass level without moving the speakers further from the wall, fit the foam bungs in the port tubes. (Figure 6) If the central image is poor, try moving the speakers closer together or toeing them in so they point just in front of the listeners. (Figure 5) If the sound is too harsh, increase the amount of soft furnishings in the room (for example use heavier curtains), or reduce it if the sound is dull and lifeless. Test for flutter echoes by clapping your hands and listening for rapid repetitions. Reduce them by the use of irregular shaped surfaces such as bookshelves and large pieces of furniture. ensure the speakers stand firmly on the floor. [. . . ] 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. 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. [. . . ]
