User manual CABASSE ALTURA

[. . . ] The tweeters of the speakers must be roughly at the same height of the listener's ear when the listener is in sitting position. No solid object or piece of furniture should be placed between the speakers and the listener. An effect of mask, even partial disturbs completely the sound reproduction as it attenuates the high frequencies and also, in most cases, the midrange frequencies. placing the speakers in niches is not recommended. [. . . ] In order to connect loudspeakers properly, it is most important to keep in mind the following two factors: cable section and phase. Se, switch the system to mono while music is being played. If the amplifier does not have a phase inversion switch, it will be necessary to change over the connections on one only of the loudspeakers. If in correct phase, the image should be distinctly located between the loudspeakers with a slight loss of bass and low midrange level. If the image is confused and not centrally located and there is a drastic loss of bass and low midrange level, recheck your connections. With a crossover point below or around 150 Hz, the installation position of subwoofers is not limited as human ears and brains are not able to identify the emitting point of such low frequencies. To get the best result, it is recommended to try different positions and choose the one giving the best response in the low frequencies, taking into account the room acoustics. 2 possibilities are offered to connect the subwoofer with your system: The low level one requiring the use of the Cinch RCA LINE IN To get the full sonic potential of Cabasse loudspeakers and avoid power losses, the cables connecting the speakers to the power amplifier must have the lowest possible electrical resistance. To help you in choosing the correct cable gauge, follow diagram. And LINE OUT9 terminals and shielded coaxial connectors, the high level one requiring the use of the HIGH LEVEL INPUT0 and HIGH LEVEL OUTPUT- terminals and standard loudspeaker cables. The inputs are stereo ones, the mix of the L (left) and R (right) low frequencies being done by the amplifier of the subwoofer. If the input signal is already mono, only one input L (left) or R (right) should be used. Before operating the unit, be sure that the operating voltage of your unit is identical with that of your local power voltage. In order to maintain the phase relationship and frequency balance of the loudspeaker system, both loudspeakers must be properly connected to the power amplifier. When properly connected, the cones of the drivers of both loudspeakers will move in the same direction when driven by identical speakers will move in the same signals. If the cones move in opposite directions, the resulting out of phase signals will create a perceptible power loss, particularly in the low frequencies. In either case, always connect red or plus to red or plus and black or minus to black or minus. Connections should be identical for both channels. To check that the speakers are in correct pha- Connections to the LINE IN8 If your preamplifier or your integrated amplifier is fitted with a stereo low-level output, then connect its L (left) and R (right) outputs to the L (left) and R (right) LINE IN0 inputs of the subwoofer. If your amplifier offers a one mono output, connect it to either the L (left) or the R (right) subwoofer LINE IN0 inputs. Connections HIGH LEVEL OUTPUT- plugs These outputs can be used to bring the signal to the main loudspeaker systems. The signal from the L (left) and R (right) HIGH LEVEL OUTPUT- plugs is the one being brought in by the HIGH LEVEL INPUT0 connectors. [. . . ] Positioning of the speakers: if possible, try to match with the S2 drawing, with the LARGO subwoofer in the front area facing the listening spot. Its position against a wall reinforces the extreme low register and limits the reflections between 80 and 200 Hz. However to obtain the best result, it is always necessary to carry out tests according to the acoustics of the room. Attention, on some sensitive TV-sets, the magnetic shielding of the LINEA TV speaker might not be effective enough because of the radiations throughout the diaphragm of the tweeter. [. . . ]
