DSP presets

This chapter gives details of the DSP presets and their parameters, and describes how to

modify them.

DSP presets

The G68 Digital Surround Controller provides two types of DSP preset. One set is available if the input is two-channel; eg from a traditional stereo source or a two-channel DVD-A. The other set is available if the input is 5.1 or 6 channels of discrete audio; eg from a Dolby Digital DVD-V or a music DVD-A. The DSP presets available in each set are described in the following pages.

Speaker layouts

The G68 Digital Surround Controller provides great flexibility in the way in which you use the loudspeakers in your system. For example, the speaker step of the Configuration Wizard allows you to use the subwoofers and centre speaker only for movie material see Configuring speakers, page 28. With the Meridian Configuration Program you can specify three different speaker layouts, each with a different use of subwoofers and centre speaker:

Layout	Description
Music	For music presets: two-channel (eg Trifield) and
	multichannel (eg Discrete).
Logic	For two-channel movie presets: eg PLIIx Movie.
5.1 Movie	For multichannel movie presets: eg Cinema.
