the speaker, which points towards the positive lobe. (figure 5)
To optimise the smoothness of sounds panning from the front of the room to the back and vice versa when speakers are used in dipole mode, we recommend that the side speakers have their positive lobes (arrows) pointing towards the front of the room and the rear speakers have their positive lobes (arrows) pointing towards the centre of the rear wall. (figure 6)
Stray magnetic fields
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 0.5m (20 in) from the speaker. LCD and plasma screens are not affected by magnetic fields.
Connections (figure 7)
All connections should be made with the equipment switched off.
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.
The terminals accept 8mm (5/16 in) spades, bared wire ends or round pins up to 5mm (3/16 in) diameter and 4mm banana plugs.
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.
Ask your dealer for advice when choosing cable. Keep the total impedance below the maximum recommended in the specification and use a low inductance cable to avoid attenuation of the highest frequencies.
Fixing the speaker in place
The speakers may be fixed to a wall using screws in the range 5mm to 6mm diameter (No.10 to No.12). On the back of the cabinet are three wall plates. The screw head should be inserted into the round part of the aperture and slid fully along one of the slots. (figure 8)
Ensure, especially when fixing to drywall panels, that the screw length and wall plug security are sufficient to hold the weight of the speaker. B&W can accept no liability for any failure of wall or ceiling fixings.
Use the template provided to mark the screw positions. The outside dimensions of the template correspond to the rear of the cabinet.
Stick 4 of the clear
Adjust the protrusion of the screws such that the rubber pads are a friction slide on the surface when the wall plates are hooked over the screw heads. (figure 10)
Always check and ensure that:
•All the screws slide right to the ends of the slots in the wall plates.
•Screw protrusion is adjusted so that the rubber pads provide enough friction to prevent the speakers sliding out of position.
The cable may be routed in the grooves in the rear panel.
Shelf mounting is not recommended as the moulded cabinet has a draft taper and will lean forward.
Mode selection (figure 11)
Use the switch on the front baffle to select between monopole and dipole modes. In the ● position, the speaker is monopole and in the ●● position it is dipole.
Experiment to find the settings best suited to your requirements. Typical combinations are:
•All surround speakers monopole
•Side speakers dipole, rear speakers monopole
•All surround speakers dipole
It would be unusual, but not impossible, to set side speakers to monopole and rear speakers to dipole.
Aftercare
The cabinet surfaces usually only require dusting. If you wish to use an aerosol or other cleaner, remove the grille first by gently pulling it away from the cabinet. 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. Avoid products that are abrasive, or contain acid, alkali or
