User manual B&W OVALE

[. . . ] However, not grounding the appliance may increase the level of hum breakthrough. When using an extension power-supply cord or a power-supply cord other than that supplied with the appliance, it should be fitted with the appropriate moulded-on plugs and carry safety approval appropriate to the country of use. 12 Power Cord Protection ­ Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed on or against them, paying particular attention to cords at plugs, convenience receptacles and the point where they exit from the appliance. 13 Cleaning ­ The appliance should be cleaned only as recommended by the manufacturer. [. . . ] 9 Heat ­ The appliance should be situated away from heat sources such as radiators, This enables the system to function as a combined full range loudspeaker and subwoofer, allowing the user to save space in a home theatre installation by avoiding the need for a separate subwoofer unit. Please read this manual fully before unpacking and installing the product. It will help you to optimise its performance. As the loudspeaker is mains powered, you should pay particular attention to the safety warnings. B&W maintains a network of dedicated distributors in over 60 countries who will be able to help you should you have any problems your dealer cannot resolve. In that case it may be placed directly below the centre of the screen if there is sufficient room. This feature only operates if the AUTO SENSE switch (figure 6C) is set to ON. On first connecting the speaker and turning the POWER switch ON, the initial surge is enough to turn the amplifier fully on and the LED (figure 7) near the logo at the bottom of the front panel glows green. If no signal is detected after a period of approximately 5 minutes, the amplifier switches automatically to standby and the LED glows red. In this mode the power consumption is approximately 4 watts. All connections should be made with the equipment switched off. Even moving large pieces of furniture can have an effect. If the central image is poor, try moving the speakers closer together or toeing them in so they point at or just in front of the listeners. (figure 8) 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 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. Whenever possible fit the spike feet supplied after you have optimised the positioning. They are designed to pierce through carpeting to the floor surface. Initially, screw the lock nuts fully onto the spikes and screw the spikes fully into the threaded inserts in the base of the speaker. If the cabinet rocks, unscrew the appropriate spikes until the speaker stands firmly on the floor and lock them in place by tightening the lock nuts against the base. If you do not have a carpet, use a protective disc under the spikes to protect the floor surface. [. . . ] However, some amplifiers invert the signal between input and output and, if you are using such an amplifier to feed the full range part of the speaker, you should set the switch to 180° (inverting), otherwise you will suffer a loss of bass through cancellation. 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. With smaller screens it may be more realistic to have the left and right speakers closer together than you might for audio alone. Adjust the levels of the three front speakers to get a smooth transition of sounds as they pan across the screen. [. . . ]
