Acoustic Energy Linear One Connecting, Conventional single wire connection, Bi-Wire Connection

5. 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), bi- wired 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. 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 guidence 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 each speaker should be kept as short as possible consistent with each being of equal length.

•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
