Water and Moisture - The appliance should not be used near water - for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool and the like. [. . . ] Wide Dispersion means that the area in front of the loudspeakers where a full stereo image is achieved is a great deal wider than with other loudspeakers. This ensures substantially better sound across a larger area within your listening room. To take full advantage of DALI DJ-F4T's Wide Dispersion, the loudspeakers should face straight ahead and not be angled in towards the listening position unless the two loudspeakers are placed very far apart. The DJ-F4T tweeter module is especially developed for this loudspeaker. Its unique design ensures that Wide Dispersion is more than just a name ­ you can tell the difference. Figure 6. DALI DJ-F4T High frequency module: Soft dome tweeter and ribbon tweeter 7 Placement Before setting up and connecting your new DALI DJ-F4T loudspeakers, you should find the best possible placement relative to your listening position. It is a good idea to follow these simple guidelines: Avoid as far as possible any objects between the loudspeakers and the listening position. Obstacles can have a detrimental effect on tonal balance. Ideally, the distance from the listening position to each loudspeaker should be the same as the distance between the left and right loudspeakers (Figure 7). In a surround installation, the speakers should be placed in a symmetrical configuration (Figure 8). Figure 7. Surround setup 8 Placement of DJ-F4T Vokal The DJ-F4T VOKAL center speakers have been specially designed to be positioned close to the large surface of the TV screen - and can be placed either above or below the screen, as required. For the optimal listening experience, the right loudspeaker (as seen from the listening position) must be connected to the amplifier output terminals marked "R" or "Right. " The left loudspeaker must be connected to the amplifier output terminals marked "L" or "Left. " Even a single loudspeaker connected out-of-phase in a stereo or surround installation will make the bass weaker and the stereo image unfocused. If you are using DALI DJ-F4T in a surround system, follow the instructions included with your surround amplifier. We recommend DALI Connect Banana Plugs. Figure 13. Connecting bare loudspeaker wire 11 Single wiring - DJ-F4T 1, On Wall, Vokal 1 For normal single wiring, connect loudspeaker cable as shown (Figure 15. ). Figure 15. Single wiring Bi-wiring - DJ-F4T 2, 5, 6, 7, Vokal 2 The top terminal pair is internally connected to the crossover network's high frequency section. The bottom terminal pair is internally connected to the crossover network's bass section. When bi-wiring or bi-amping, ALWAYS remove the metal jumpers between the terminals before connecting cables. For bi-wiring, connect two sets of loudspeaker cable, one to the top terminals and one to the bottom terminals. At the amplifier end, connect both sets of loudspeaker cables to the same pair of terminals on the amplifier (Figure 16). Figure 16. Note: When using two DJ-F4T SUB, the best results are normally achieved by positioning the two subwoofers relatively close to each other (1 - 2 metres).

Connection to stereo preamplifier 14 Level adjustment When you have decided upon which method of connection you want and positioned the subwoofer, you can commence the exciting process of tuning the system. Please note that positioning the subwoofer will have a lot of influence on its contribution to the overall sound. [. . . ] In the same way that a mirror reflects light, they will reflect sound from the speakers at almost full strength but with a slight delay due to the relatively low speed of sound. This will disturb the precision and spacial effect of sound reproduction. Try hanging a soft textile surface behind the speaker, place a rug in front of it, or place a large plant to the side and experience the surprisingly large effect doing so will have on the quality and precision of the sound. Once you are happy with the positioning of your speakers, it is important to ensure that they are completely stable. [. . . ]
