DTS SETUP

Under this menu, the Dynamic Range Control of DTS Digital Surround can be adjusted as well as the
settings for DTS Neo: 6 Music.
Dynamic Range Control : This is the same configurable Dynamic Range Control feature as

described above at Dolby Setup, the only difference being the soundtrack is now in DTS format.

DTS Neo: 6 Music : Please refer to the same description about ‘Adjusting Listening Modes’ under

the ‘Listening Mode’ of the Main Menu discussions.

Enhanced Stereo : Please refer to the same description about ‘Adjusting Listening Modes’ under

the ‘Listening Mode’ of the Main Menu discussions.

DTS SURROUND MODES

The following are further descriptions about the DTS surround modes.

DTS - ES EXPANDED SURROUND ™ (DTS ES)
This is a new multi-channel digital format which greatly improves the 360° spatial sensation of the
Surround impression thanks to the greater space expansion of the surround signals, providing high
compatibility with the conventional DTS format.

In addition to the 5.1 channels, the expanded DTS-ES Surround also offers the back surround (also
sometimes called the “surround centre”) in reproduction, providing a total of 6.1 channels. The
expanded DTS-ES Surround includes two formats, with two different methods of surround signal
recording, as follows:

DTS-ES™ DISCRETE 6.1
Since the signals of the 6.1 Surround channels (including the back channel) are completely
independent, it is possible to achieve the sensation that the acoustic image is moving about freely
among the background sounds, 360 degrees surrounding the listener.

Although maximum quality is achieved with sound tracks recorded using this system and reproduced
using the DTS-ES decoder, when played with a conventional DTS decoder, the back surround channel
is automatically downmixed in the surround right and surround left channels of the surround system,
in such a way that none of the signal components are lost.

DTS - ES™ MATRIX 6.1
In this format, the additional signals of the back channel receive a matrix encoding and are inputted
into the right and left surround channels. During reproduction they are decoded to the right, left and
back surround channels.

Since this bit-stream format is 100% compatible with conventional DTS signals, the DTS-ES Matrix 6.1
format effect can also be achieved from sources with DTS-ES 5.1 signals.

Naturally, it is also possible to reproduce from a DTS 5.1 channel decoder, signals recorded in DTS-ES 6.1.

When a DTS-ES decoder processes a discrete DTS-ES 6.1 or in Matrix 6.1, these formats are
automatically detected and the Optimum Surround mode is selected. However, some DTS-ES Matrix
6.1 sources may be detected as DTS. In this case the DTS-ES Matrix mode should be selected manually
in order to reproduce them.

DTS NEO: 6™ SURROUND
This mode applies the conventional 2-channel signals such as digital PCM or analog stereo signals to
the high precision digital matrix decoder used for DTS-ES Matrix 6.1 to achieve 6.1-channel surround
playback. DTS Neo: 6 surround includes two modes for selecting the optimum decoding of the signal
sources:
DTS NEO: 6 CINEMA : This method is ideal for the reproduction of movies. The decoding takes

place by emphasizing the separation in order to achieve the same atmosphere with 2-channel, as
with 6.1-channel sources.

DTS NEO: 6 MUSIC : Mainly recommended for music reproduction. The right and left front

channels do not pass through the decoder and are reproduced directly so there is no loss in sound
quality, and the effects of the right surround, left surround, central and back surround channels add
a natural sensation of expansion of the sound field.
