NAD T755 - Dolby Setup; Dts Setup; Dts Surround Modes

DOLBY SETUP
Under this menu, the Dolby Digital’s Dynamic Range Control can be adjusted as well as the settings for
Dolby Digital Pro Logic IIx Music.
Dynamic Range Control: You can select the eective dynamic range (subjective range from soft
to loud) for playback of Dolby Digital soundtracks. For fully cinematic eect, always select 100%, the
default. Settings of 75%, 50%, and 25% progressively reduce dynamic range, making soft sounds
comparatively louder while limiting the peak loudness of loud ones.
The 25% setting will yield the least dynamic range and is best for late-night sessions or other times
when you wish to retain maximum dialog intelligibility while minimizing overall volume levels.
Dolby Pro Logic IIx Music: Please refer to the same description about “ADJUSTING LISTENING MODES”
under the “LISTENING MODE” of the Main Menu discussions.
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 congurable Dynamic Range Control feature as described
above at Dolby Setup, the only dierence 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.
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 oers 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 dierent 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.
