Planning a system

Introduction

2

Before unpacking and setting up your digital surround processor it is worth spending a little time planning how to set up the speakers, and the other components of your hi-fi system, so that they will give the best results when used in conjunction with the 565.

The digital surround processor can be configured to work with a wide range of different speaker layouts. These include combinations of a centre speaker, up to four surround speakers, and up to three subwoofers, with the main left and right speakers.

The following pages show some of the speaker layouts particularly recommended for use with the digital surround processor. For more information about these and the other layout options see Specifying the speaker layout, page 22.

When you are playing a 5.1 source the digital surround processor will choose the appropriate decoding for the layout you are using.

Three-channel surround system (Layout G or L, No Surrounds)

Adding a centre speaker is the most significant step you can take to upgrade a two-speaker system, whether you are using the system for cinema, music, or a combination of the two. It reinforces the central image, and allows the left and right speakers to be further apart for a wider soundstage. This gives a more realistic and stable three-dimensional image of the original recorded sound, for outstanding music and cinema reproduction.

The centre speaker needs to be of equivalent quality, and tonally matched, to the main left and right speakers. It should also have good power handling as it regularly plays louder than the left and right speakers. The ideal position is at the same height as the left and right speakers, and above the TV in a home cinema system.
