User manual ACOUSTIC ENERGY LINEAR 1

[. . . ] Installation The Linear One is intended to be used mounted on speaker floor-stands relatively clear of room boundaries. Alternative mounting arrangements such as wall brackets are possible although these may result in reduced performance. If wall brackets are to be used they should be as rigid as possible and firmly attached to brick-built walls. The construction style, rigidity and dimensions of the floor-stands are of critical significance to the performance of the Linear One. [. . . ] However, whether used against the long or short wall, it is important Diagram One angle inward 3. 0 metres 0. 5 metres from back wall Reflection region. Keep similar each side.

Connecting Connecting your Linear Ones to an amplifier is fundamentally a simple process, however, there are some choices to be made and issues to consider concerning connection mode, connectors and cable type. Each Linear One is fitted with two pairs of binding-post terminals - one pair each for the low frequency and high frequency drivers. Two pairs of terminals enables Linear Ones to be connected conventionally (single wire), biwired or bi-amplified. As supplied, the high and low frequency terminals are connected together by metal shorting links ready for conventional connection. The terminals can accept either stripped wires, spade connectors, or 4mm plugs. 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 guidence 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.

The Linear Range The Linear One is part of a range that includes the Linear Three floor-stand speaker, the Linear Centre centre channel speaker and the Linear Sub active sub-woofer. Linear One, Linear Three and Linear Centre incorporate time-aligned drivers to improve image quality, depth and focus. [. . . ]
