User manual ACOUSTIC ENERGY LINEAR 3

[. . . ] Damage to a driver will at best degrade a Linear Three's performance and at worst result in its complete failure. Any cleaning should only require a soft cloth, slightly dampened if necessary. Installation The Linear Three is a floor-standing loudspeaker intended to be positioned clear of room boundaries and coupled to the supporting floor through spikes. If spikes are inappropriate for your floor covering, metal protection pads, coins for example, maybe used between the spike and the floor. [. . . ] Once your Linear Threes are connected (see Section 5) and working, and you begin to become familiar with their performance, it is likely to be worthwhile experimenting a little more with their positioning. Reducing the distance between the speakers and the rear wall will increase the level of bass and low midrange making the speakers sound warmer. The warmth however is likely to be gained at the expense of some mid-range clarity and stereo image focus and depth. Increasing the toe-in angle of the speakers may regain some image focus but again this is likely to be at a cost of image width and openness. Learning through experimentation how Linear Threes behave in your room will help you find the optimum solution. The Linear Three is magnetically shielded and can be used in relatively close proximity to CRT screens. Don't worry if, thanks to the architecture or layout of your room, it is not practical to follow each requirement. The most important thing is to experiment with the different options that are practical and find the one that works best. While it is often the first instinct to position a pair of speakers against the shorter wall of a rectangular room, it is often the case that a position against the longer wall will produce better results. This is because the long wall position tends to result in less prominent reflections from the side walls of the room. 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 Threes 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 Three 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 Threes to be connected conventionally (single wire), bi-wired or bi-amplified. As supplied, the high and low frequency terminals are connected together by metal 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. [. . . ] Your ears too will take some time to adjust to the new sound, so revisiting the system set-up, speaker positioning especially, is best left for a few days. 8.
