Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation JBL S4VC, S4HC, S4Ai.

    N OTE : It is extremely important to place the tweeter/mid-bass arrays for each of the center , left and right speakers at the same height. The EOS waveguide containing the tweeter in the center channel speaker should be no more than two feet higher or lower than those in the left and right speakers. This preserves the “localization integrity” [...]

    In a 7.1-channel system, where two additional S4Ai speakers may be mounted in the rear wall, the positive phase arrays for all speakers should fire toward the rear corners, as shown in Figure 11. Thus, the side left speaker should be configured with its phase switch in the IN position, and the speaker on the right should be config- ured with its ph[...]

    15 H owever , since it is not possible to “toe-in” flush-mounted speakers, the next step is the strategic placement of absorptive materials on the side walls.

    16 The best arrangement of the absorptive and nonabsorptive surfaces in the room can be seen in Figure 24.

In this regard, the ratios of room dimensions are the critical factor . Rooms having equal dimen- sions are the[...]

    20 Standing-wave energy tends to be concentrated in the corners of rooms, which is why placing a subwoofer in the cor- ner tends to increase its bass output. Because of this, it is possible to break standing waves up somewhat by “break- ing up” the corner . This can be accomplished by placing a column of thick, absorptive materials in the corne[...]
