Enable greater maximum sound output ­ often useful for effectively reproducing special effects in Home Theatre applications. Smooth out the effects of low-frequency room resonances. Setting the controls Line and speaker level inputs There are three controls to consider: · · · · see the section below on fine tuning. Set the volume control initially to the half way (12 o'clock) position, then see the section below on fine tuning. Set the PHASE switch initially to 0°, then see the section below on fine tuning. · · The LOW-PASS filter frequency The VOLUME control The PHASE switch · · Fine tuning The setting of the EQUALISATION switch affects only the signal via the decoder input. Position A is optimised to allow the subwoofer to provide the highest listening levels, while position B gives greater bass extension. The optimum settings of the PHASE switch and the LOW-PASS filter frequency are inter-related and also dependent on the low-frequency cut-off characteristic of the satellite speakers and the relative positions of all the speakers in the installation. Set the system up in the preferred position and play some programme with a steady bass content. The optimum setting for the LOW-PASS cut-off frequency depends on several variables ­ the bass performance and power handling of the satellite speakers, the number of subwoofers used and their position relative to the satellite speakers. The range 80-90 Hz is a good starting point for the LOW-PASS frequency. Unless two subwoofers are used to preserve separate right and left channel information and are sited close to the relevant satellite speakers, using a higher cut-off frequency may compromise the stereo image and should only be considered if the bass performance of the satellite speakers is particularly limited. At each setting of the cut-off frequency, listen with the phase switch in both positions. The correct one is that which gives the fullest bass and that will depend on the bass characteristics of your satellite speakers and the relative distances of the subwoofer(s) and the satellite speakers to the listeners. When using more than one subwoofer, ensure that each one has its cut-off frequency and phase switch set the same way. If at any time you make changes to the amplification of the system such that you change from speaker to line level connections to the subwoofer, it is worth checking the phase setting again, as the speaker level and line level high-pass filter phase characteristics of the subwoofer are different. Set the loudness of the subwoofer relative to the satellite systems to your liking. One that sounds impressive on one piece may sound overpowering on another. Listen at realistic levels as the perception of balance varies with sound level. If you get problems with lumpy bass ­ if certain bass notes are exaggerated more than others ­ then you probably have a room interface problem and it is worth experimenting with the placement of the subwoofer. What may seem like small changes in position ­ 15cm (6in) or so ­ can have a profound effect on the sound. 7 Decoder input There are three controls to consider: · · · If you are using two subwoofers for stereo audio, stereo separation is improved if each channel has its own subwoofer, providing each one is sited close to the relevant satellite speaker. [. . . ] Prenez simplement garde de ne pas vous piquer. L'ASW TM 4000 n'a pas seulement été étudié pour les installations de Home Cinéma, il conviendra naturellement à la reproduction de haute qualité des très basses fréquences de toute chaîne sonore. Ce subwoofer apporte, en plus d'une extension spectaculaire de la réponse vers l'extrème-grave, une amélioration non négligeable de la clarté de reproduction du médium, grâce à la réduction du travail demandé aux enceintes principales. Vous pouvez donc l'utiliser à proximité de votre téléviseur. Veuillez lire attentivement et totalement cette notice avant d'utiliser votre subwoofer. [. . . ]
