dtsDigitalSurround

The “dts” multi-channel film sound system was originally developed to replace analogue film soundtracks, using digital recordings consisting of six discrete channels. This system has now been further developed to provide spatial sound reproduction in the home situation.

The six channels (5.1) are encoded / decoded in original quality, i. e. with 20-bit resolution, and recorded using only slight data compression. The 5.1 loudspeaker configuration, currently the standard arrangement for home cinema systems, is ideal for playback.

Dolby Digital Ex is an expansion of the Dolby Digital process. In order to optimise the spatial reproduction further, the surround speakers are set up to the sides of the listening position, and supplemented by one or two additional back loudspeakers (if 2 back speakers are used, both of them reproduce the same signal).

Dolby Digital EX generates six full-range channels from the 5.1 signal. This is achieved by a matrix decoder which produces a third surround channel from the two surround channels of the 5.1 signal. Dolby Digital EX works best with film and sound material encoded with extra Dolby Digital EX.

dtsES/discrete

DTS ES is an expansion of the dts digital surround process. The surround loudspeakers are supplemented by back speakers in a similar way to Dolby Digital EX. The sound signal is produced during the decoding process from the surround channels by means of an additional stage.

In contrast, DTS ES discrete produces the sound channel for the back speakers from a sixth channel which is recorded completely separately.

STEREO/MONOmode:

Stereo

mode for stereo reproduction

Note:

Amulti-channel signal is converted into a stereo signal (downmix), and reproduced via the main left and right loudspeakers.

Mono	mode for mono reproduction

All channels are mixed down onto the Centre loudspeaker *).

MonoI

mode for twochannelTVsound

Generally ChannelI transmits the synchronised sound. The signal from Channel I is reproduced via the Centre loudspeaker *); Channel II (original sound) is suppressed.

MonoII

mode for twochannelTVsound

Generally Channel II transmits the original sound. The signal from Channel II is reproduced via the Centre loudspeaker *); Channel I (original sound) is suppressed.

Notes:

*) If no Centre speaker is present (see ‘Loudspeaker Menu’), the Centre channel is mixed onto the left and right main speakers.

Not all signal sources (DVDs, CDs etc.) which are encoded with Dolby Digital or DTS Digital Surround contain the full 5.1 information. Even if the screen indicates that a channel is present, that does not necessarily mean that sound signals will constantly be present at that loudspeaker.

In every mode of reproduction signals can be made available on the sub-woofer channel, depending on the loudspeakers selected in the 'Loudspeaker Menu'.
