[. . . ] In monopole mode, only the two drive units on the front face operate. In dipole mode, the front tweeter is disconnected; the two side firing drivers are brought into operation and the crossover frequency to the bass unit is lowered. The side units are connected out of phase with one another, which creates a wedgeshaped null zone at right angles to the wall. If the listeners sit within this zone, they become less aware of the location of the speakers and hear more reflected sound; hence the diffuse nature of the sound field. [. . . ] 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. Push the wall frame into position and secure. For all situations, this is done by screwing up the swing-out clamps. The initial turn of the screw will cause the clamps to swing out into position and further turning will draw them towards the back of the wall. In retrofit situations without the PMK for protection, take care not to over tighten the clamps, otherwise the plasterboard will crush and weaken the fixing. (figure 11) Decorating is best carried out at this stage, before the baffle and drivers are fitted. The wall frame may be painted using any normal household paint. Never paint over the grille fabric as this will clog the pores and impair the sound. We recommend you do not attempt to paint the speaker baffle. The combination of a black grille frame in front of a black baffle ensures that the cross pattern of the grille frame is least visible, even with white cloth. Connect the cable to the speaker as described in the "Connections" section above and screw the baffle into the wall frame using the pan head screws provided. The grilles are a push fit onto the baffle, but before fitting them, balance the installation following the processor instructions and select dipole or monopole mode as preferred (see below). 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. Use the switch on the front baffle to select between monopole and dipole modes. Retrofit Use a stud finding tool to locate the position of the studs behind the plasterboard panels. use the template provided to mark the position of the speaker. The outside edge of the template represents the size of the wall frame. Do not allow the template to overlap a stud position or the swing-out clamps will not operate correctly. mark along the inner edge of the slots in the template.
