Configuring the digitalsurround processor

This chapter explains how to configure the digital surround processor to

suit the speaker arrangement you want to use, and the other equipment in

your system.

The first stage in configuring the digital surround processor is to choose

one of the standard Type settings, which are designed to set most of the

parameters to typical values.

The next stage is to configure the 565 for those aspects of your layout that

differ from the standard setting you chose.

The third stage is then to set up the speaker outputs, and adjust the delay

of each output to time-align the system. These three stages are described

in detail in the following sections.
