User manual ACOUSTIC ENERGY LINEAR CENTRE

[. . . ] Damage to a driver will at best degrade a Linear Centre's performance and at worst result in its complete failure. The enclosure surfaces should also be handled sympathetically. Any cleaning should only require a soft cloth, slightly dampened if necessary. Be wary of using any polishes or solvent based cleaning agents. [. . . ] Each of these termination methods is potentially equally effective and the choice is likely to be influenced by type of speaker cable used. Your dealer, distributor or cable manufacturer will be able to offer advice. Conventional [single wire] connection Conventional connection requires that the shorting links remain in place between the high and low frequency terminals. Simply connect the speaker cable to either pair of terminals ensuring correct connection polarity as described below. Bi-Wire Connection Bi-wiring separates the low and high frequency connections and can provide enhanced sound quality. A second set of cables (or alternatively, a multi-way bi-wire cable) is required. The shorting links should be removed and stored for any subsequent single wire use. The two cables for each speaker should be connected in parallel to the amplifier terminals. At the speaker, one cable should connect to the high frequency terminals and one to the low frequency terminals. Ensure correct connection polarity as described below. Bi-Amplifier Connection Bi-amplifier connection adds a second power amplifier to the system so that high and low frequency sections have dedicated amplifiers. Significantly enhanced sound quality is possible. One stereo amplifier should be connected to the high frequency terminals of each speaker and a second stereo amplifier connected to the low frequency terminals. The shorting links should be removed and stored for any subsequent single wire use. Ensure correct connection polarity as described below. Follow the amplifier manufacturer's guidance on connecting the amplifier input signals. The shorting links must be removed for bi-amplifier connection. Failure to do so will likely result in damage to the amplifiers. Connection Polarity It is important when connecting speakers to ensure that each terminal is connected with the correct polarity. Positive speaker terminals should always be connected back to amplifier positive terminals, and negative speaker terminals connected back to amplifier negative terminals. Performance will be seriously degraded if connections are made with incorrect polarity. Take care when connecting cables not to touch the negative and positive terminals together and "short-circuit" the amplifier. Make connections with the amplifier switched off. Choice of cable type will be influenced by the characteristics of other components in your hi-fi system and your dealer or distributor will be able to advise. Even so, there are some simple guidelines to consider: · · Cable runs to should be kept as short as possible. Short cable runs are especially important if the cable is of relatively small cross-sectional-area.
