User manual ACOUSTIC ENERGY LINEAR CENTRE

[. . . ] Installation The Linear Centre is intended to be used in a home theatre system located either directly above or below the screen. It can be stood either directly on a furniture unit, integrated within a screen stand, mounted on a dedicated speaker stand or on a wall using appropriate bracket hardware. Best results are likely to be gained if the Linear Centre is directly coupled to the floor via a dedicated, spiked stand. If the screen stand is to carry the Linear Centre it is advisable to de-couple it from the screen with the supplied adhesive rubber feet so that its does not disturb the picture. [. . . ] 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. 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. Follow the amplifier manufacturer's guidance on connecting the amplifier input signals. 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. 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. · If the cable is advertised as "directional" care should be taken to ensure that its orientation is as recommended. Page 3 Linear 7 Rev C 3 16/8/05, 11:18 am 6. Amplifiers The Linear Centre is a relatively high sensitivity speaker that does not require a generously rated power amplifier for adequate volume levels to be achieved in an average listening room. A minimum of 25 and maximum of 175 Watts into 8 Ohms per channel is recommended. Linear Centre also offers a relatively easy load to the amplifier and does not make unusually heavy demands on its power delivery. [. . . ] Linear Sub Linear Sub is an active sub-woofer perfect for enhancing Linear One bass performance or handling the low frequency effects channel in Linear audio-visual systems.
