User manual FOCAL PROFILE IW 908 MOUNTING KIT

[. . . ] Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. WARNING: To reduce the risk of fire or electric shock, this apparatus should not be exposed to rain or moisture and objects filled with liquids, such as vases, should not be placed on this apparatus. To completely disconnect this equipment from the mains, disconnect the power supply cord plug from the receptacle. The mains plug of the power supply cord shall remain readily operable. [. . . ] In such a configuration, you will not only benefit from an optimum perception of the bass frequency range but the bass level will also increase by 6dB (fig. If a particular disposition of the room does not allow placement of the subwoofer in a corner, we recommend that you try different configurations until you find the best possible sound. Generally, the subwoofer should be placed along the front wall of a listening room. As bass frequency waves are omni-directional, the sound dispersion will not be affected if a piece of furniture or an object is placed between the subwoofer and the listening area. It is then possible to hide the Profile behind a piece of furniture as long as the bass frequency dispersion is not affected. Magnetic disturbance The Profile generates a magnetic field that may interfere with other sensitive household appliances. It is strongly advised to not place the Profile closer than 50cm (20") to your TV screen. Frame geometry as well as colours can be severely distorted by a magnetic field if the loudspeaker is placed to close to the cathode ray tube. Generally, all sensitive media (audio tapes, video tapes, magnetic data storage, projector and CRTS overheadprojector) should not be placed close to any non-shielded loudspeaker. Start-up and shut-down Turn the power switch on the back of the unit to the "On" position. Start-up can also be attained (ex: setting parameters of the subwoofer without an analog signal, see following chapter) by pressing the button on the remote. Note 1: it is possible to simultaneously connect the stereo inputs and the LFE from the amplifier for both stereo and multi-channel listening. These choices will be conserved in the memory as "Hi-fi" and "Cinema". note 2: the menus on the "slave" subwoofers connected to the input "Digital" are partially deactivated. Only "Gain" and "Phase" are active on each subwoofer to allow easy adaptation to room acoustics. Low Pass Mode Active digital crossover, adjustable from 50 to 150Hz, 5Hz steps, 24dB/octave slope. set the frequency according to the characteristics and performance of the associated speakers. On stereo program, with speakers that already perform well in bass frequencies, choose a crossover value lower or equal to 80 Hz to give lower bass support without overloading the lower octave. In multi-channel mode, this value can rise (to 100 or 120Hz) to give more impact in the bass. Use a value higher or equal to 120Hz when the speakers are compact satellites with little bass performance. Note 1: the inactive mode (Off) can be chosen when the active filters of the amplifier are used. Note 2 : the active crossovers of the Profile subwoofer, due to their extreme precision, can work simultaneously with those of an AV amplifier. [. . . ] Note 2 : it is possible, whilst listening, to compare the position 0° and 180° (inverted phase) directly from the menu, without fine-tuning by steps. This easy phase inversion solution can simplify final adjustment. Gain Mode It is possible to assign a different gain (from -6dB to +6dB) according to either a music or cinema program that would benefit from a higher level. This level can be kept in memory on the buttons Select Hi-fi and Cinema. [. . . ]
