User manual FOCAL CUB2

[. . . ] Caution : To prenvent yhe risk of electric shock, do not remove cover (or back). An external aerial must always be kept away from high voltage wires or electric circuits. It must also be kept away from high-density lighting and places where it could fall on high voltage wires or an electric circuit. When installing an external aerial, please remember to avoid any contact with such circuits, as there may be a risk of lethal danger. [. . . ] We advise you to keep this guide so that you can consult it when needed. Active crossover with adjustable crossing frequency: it allows to adjust with high accuracy the frequency range according to the performances and characteristics of the other used loudspeakers. High level stereo inputs: low level inputs on RCA and high level binding post terminals for a highly flexible system. The Focal-JMlab guarantee only applies if page 23 is returned to us within 10 days of purchase. "High level" inputs When using a standard twochannels stereo amplifier, the Cub2 must be connected through the "high level inputs". The two stereophonic loudspeakers will then have to be connected directly to the high level outputs of the subwoofer (fig. Low level inputs on RCA When using a two-channels amplifier with pre-out line outputs, the Cub2 must be connected through RCA stereo inputs "line inputs Right/Left" (fig. LFE input When using an audio/video multi-channel amplifier, the single LFE input of the Cub2 should be connected to the mono "Subwoofer" output of the audio/video amplifier (fig. In that case, all controls of the Cub2 will be off, except the volume control. Considering the fact that the audio/video amplifier already features all the necessary functions, this configuration is recommended for home theatre use only. Contrary to conventional hi-fidelity loudspeakers which have to be placed at a reasonable distance from the walls and the listening area corners, we advise you to place your Cub2 subwoofer in a corner of the listening area (fig. If the subwoofer is placed against only one wall or too far from the walls, the very large wavelength of the bass delivered by the subwoofer will excite the resonance of the listening room in an unpredictable way. Frequency response linearity will then be damaged and therefore the sound rendition will be affected (lack of depth, "boomy sound", poor bass, difficult or impossible coupling with the other used loudspeakers). If you put the Cub2 in a corner, the resonant frequencies of the room will be more linear and predictable. In such a configuration, you will not only benefit from an optimum perception of the bass frequency range but the bass level will also be increased by 6dB (fig. If a particular disposition of the room does not allow to place the subwoofer in a corner, we recommend you to try different configurations until you find the best possible disposition. Generally, the subwoofer should be placed along the front wall of the listening room. Because the 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. When the Cub2 is connected to the amplifier through the "high level" inputs, it is recommended to use standard loudspeakers cables with 1. When the Cub2 is connected to the amplifier through stereo "line level" or LFE inputs, use a RCA/RCA shielded cable of the required length. When the "power" control is set on auto-mode, the subwoofer will automatically switch on as soon as an audio signal is detected. when set to "power on" , the signal detector is disable and the subwoofer is continuously on.
