DolbyProLogicIIxSurround

In this process several independent signal channels (left, centre, right and surround (rear)) are recorded using two channels and a special encoding process. Since this process only requires two recording channels, it is compatible with many picture / sound systems which are already widely in use (CD, video recorder, TV etc.).

The information is decoded at playback time and reproduced in the listening room via four (left, right, 2 x rear) loudspeakers, although five speakers (with an additional front centre speaker) are preferable. Dolby Pro Logic encoded material is currently available mainly in the film and video arena, recorded on video cassettes and DVDs, but a large number of television programmes are now being produced and transmitted using Dolby Surround.

DTSNeo:6

The DTSNeo:6 process can be used both for encoded stereo material (see Dolby Pro Logic II Surround) and also for un-encoded stereo material.

The Neo:6 decoder generates – according to setting - up to 6 channels (left, centre, right, 2 x side, back centre) from this; the back centre channel can also be reproduced by 2 separate speakers if they are available.

Dolby Digital is a digital multi-channel surround system which was developed specifically for spatial sound reproduction in connection with cinema films. The process utilises five separate sound channels: three front channels (left, centre, right) and two surround channels. A sixth independent bass effect channel is also present, catering for low frequency effects (LFE). That is why such systems are said to offer 5.1 channels.

In comparison with Dolby Pro Logic II, Dolby Digital provides two independent surround channels which generate genuine spatial stereo sound, offering the same realistic stereo reproduction as provided by the front channels.

The integral Dolby Digital decoder provides the means of obtaining a genuine digital Dolby stereo cinema presentation in your own living room. The discrete digital recording process and the five playback channels guarantee a very wide dynamic range and accurate spatial orientation.

The dynamic range is the difference in volume between the quietest and loudest passages of a recording. The original soundtrack of a film generally features an extremely wide dynamic range which the surround receiver can reproduce in full.

Unfortunately not all listening rooms, and not all times of day, are suitable for exploiting the full dynamic range. For example, it may be necessary to take your neighbours’ feelings into account - especially in the late evening hours.

For this reason it is possible to reduce the dynamic range of Dolby digital encoded sound sources in such a way that quiet passages (e. g. whispered conversations) are reproduced somewhat louder, while loud passages (e. g. massive explosions) are reduced in volume slightly (see 'Main Menu').
