Configuring the digital surround processor using a computer

The 568 Digital Surround Processor provides a flexible range of customisation options which you can change to suit your own preferences and the other equipment in your system. To configure the 568 you use the Meridian Configuration program, an intelligent Windows-based application that is supplied with the 568. This allows you to create one or more custom configurations, and download them to the 568 so that they are available alongside the built-in types.

This chapter explains how to install the Meridian Configuration program, and then how to use it to create your own configurations of the 568.
