OPERATION
USING THE T 737 – SETUP MENU

DOLBY SETUP

Under this menu, the Dolby Digital's Dynamic Range Control can be
adjusted as well as the settings for Dolby PLIIx Music.
Dyn Range Ctrl (Dynamic Range Control): You can select the effective
dynamic range (subjective range from soft to loud) for playback of Dolby
Digital soundtracks. For fully cinematic effect, 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 PLIIx Music: Please refer to the item about "PRO LOGIC IIx" under
the topic "ADJUSTING LISTENING MODES" at the "USING THE T 737 - MAIN
MENU" discussions above.

DTS SETUP

Under this menu, the Center Gain settings of DTS Neo:6 Music can be
adjusted. See discussion below about "DTS NEO:6 MUSIC".
DTS SURROUND MODES
The following are further descriptions about the DTS surround modes.
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.
24
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.
Center Gain (0 to 0.5): Adjust for better center image in relation to
the surround sound channels.
