Dolby/DTS e SSP-800 incorporates both Dolby Pro Logic II and DTS Neo:6
technologies for converting a two-channel signal into an enjoyable multi-
channel listening experience. e Dolby/DTS Setup menu allows you to
modify the Dolby PLIIx Music or DTS Neo:6 Music processing settings to best
suit your personal preferences.
While they diff er in the details of their implementation and in the subjective
result, on a conceptual level they do the same thing: they analyze the
information embedded in two-channel recordings, looking for clues that can
indicate how the sound in those recordings might best be redistributed to the
various speakers in a multi-channel system, simulating a discrete multi-channel
recording.
Dolby Pro Logic IIx Dolby Pro Logic IIx Music mode has three user-adjustable parameters:
• Panorama presents a wider, deeper front soundstage. e eff ect is
somewhat signal-dependant, meaning that it is more pronounced with
some recordings and less so with others. With a good recording, however,
the eff ect can be quite dramatic. Panorama is active when the button is
highlighted.
• Centre Width determines how much of the centre-channel information
is allowed to remain in the left and right speakers. A low setting places all
of the information that creates a phantom centre image in a normal stereo
system into the centre channel speaker instead (sometimes referred to as a
“hard” centre channel). A high setting leaves this information in the left
and right speakers, fading out the centre channel speaker. Intermediate
settings provide a great compromise between the seamless spaciousness
of a great stereo system and the wide listening area of a multi-channel
system, where you don’t need to be in the “sweet spot” to hear a centre
image.
• Dimension shifts the overall balance of the processing towards the back
of the room. In very “dry” recordings lacking recorded ambience, a higher
dimension setting helps to restore a sense of space to the reproduced
sound. In extremely “wet” recordings with lots of ambience, you may
want to reduce the dimension setting to avoid excessive or distracting
spaciousness.
DTS Neo:6 By contrast, the DTS Neo:6 setting couldn’t be simpler. e only user-
adjustable parameter for DTS Neo:6 Music mode and ES Music mode is the
centre width control. It functions in a similar manner to the centre width
control for Dolby Pro Logic IIx.
