Anleitung Zusammenfassung
Introduction Welcome to the Linear Centre. Perhaps more than any other hi-fi product, speakers are sensitive to installation so please take a little time to read this manual and to follow, as far as practical, the installation guidelines it contains. Careful installation will help ensure that your Linear Centre performs optimally. Should you have any questions not covered here we are happy to try and answer them either by telephone or email. Contact information can be found in Section 11. Following this introduction, the Manual is divided into sections covering handling, installation, positioning, amplifier compatibility, connection, 2. Handling The Linear Centre is a relatively delicate precision engineered product that can be damaged by inappropriate handling. Please take care when unpacking or moving the speaker not to touch any of the drivers. 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. The packaging should be retained for future use. listening, matching products, specifications, warranty and contact information. We recommend 3. Installation that you read at least the first five of these sections carefully before installing and using your Linear Centre. 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. If a wall bracket is to be used it should be as rigid as possible and firmly attached to a brick- built wall. The Linear Centre is magnetically shielded. However, the extreme sensitivity of some CRT tubes to low levels of magnetic flux may mean that, in rare cases, the shielding may not be sufficient. Should your screen suffer picture distortion caused by the proximity of a centre speaker contact your dealer installer or Acoustic Energy for advice. The following section provides further general advice on Home Theatre speaker positioning and room layout. Page 1 Linear 7 Rev C 1 16/8/05, 11:18 am 4. Positioning The position of the speakers in a home theatre installation will have great influence over its performance. It is worth spending some time experimenting both with the finer points of speaker positioning, as well as the larger scale issues of room layout. Diagram One illustrates an idealised general home theatre speaker layout. If you are already familiar with the characteristics of your home theatre room, and the way speakers perform in it, you may already have a good feel for where to position your Linear Centre. However, installing any new speaker component provides a good opportunity to review an existing set-up and perhaps make improvements. The position requirements for a Linear Centre are as follows: • Between 0.05 and 0.5 metres from the rear wall. • Generally in-line with the display screen. • Directly above or below the display screen. Don’t worry if, thanks to the architecture or layout of your room, it is not practical to follow each requirement or the layout diagram exactly. The most important thing is to experiment with the different options that are practical and find the one that works best. Once your Linear Centre is connected (see Section 5) and working, and you begin to become familiar with its performance, it is likely to be worthwhile experimenting a little more with its positioning. For example, reducing the distance between the speaker and the rear wall will increase the level of bass and low midrange making the speaker sound warmer. The warmth however is likely to be gained at the expense of some mid-range clarity.

Connecting Connecting your Linear Centre 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. Linear Centre 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 Centre to be connected conventionally (single wire), biwired or bi-amplified. As supplied, the high and low frequency terminals are connected together by metal shorting...
