Introduction

In addition, a high data-rate version of DTS can be used to

compress five channels of CD-quality audio into the same space

as two channels of unencoded sound, allowing a DTS music CD

to provide over an hour of five-channel music, at a quality

indistinguishable from conventional CD.

MPEG Surround

MPEG Surround is the preferred audio format for DVD in PAL

territories, and along with Dolby Digital is a contender as the

standard for music and performance videos on DVD worldwide.

THX

THX versions of Dolby Digital, MPEG Surround, and DTS are

provided to give a better match between the original soundtrack

and typical domestic listening conditions.

MLP

MLP (Meridian Lossless Packing) is an audio format that allows

multiple audio channels, of up to 192kHz 24-bit quality, to be

stored on a DVD without losing any information. It can also be

used to store four-channel audio on a standard CD without any

loss of quality.

Multi-channel sources encoded onto

two channels

Several systems have been developed for encoding multi-

channel sources onto a standard two-channel analogue signal

so that they can be reproduced by a conventional stereo

system, or decoded with special equipment for multi-channel

reproduction. The 568 Digital Surround Processor provides

decoding of the two most important of these, Ambisonic and

Dolby Surround. Although the channel separation cannot be as

good as with the digital multi-channel formats, the 568 produces

excellent results with these formats.

Pro Logic

The Pro Logic preset is recommended for decoding Dolby

Surround encoded video and LaserDisc soundtracks, and films

on television. Such materials are usually identified by a Dolby

Surround symbol on the packaging, or displayed on the film

before the programme.
