The absolute system refers to the notion that most people thinking of the number 0 as
meaning nothing, e.g., no sound at all. In this system, 0 means "sound off " and larger
numbers indicate high volumes. While this is intuitive, the only way you have any idea
how loud a particular setting is would be through experience.
In the relative (THX) system, there is a calibrated, reference volume at which movies are
played in theaters, which is duplicated in your environment and referred to as "0 dB."
Regardless of how large or how small the theater, a setting of "0 dB" is always the same,
known volume. Changes from that volume level are shown as either positive (louder) or
negative (quieter). People who have spent any time making recordings will recognize that
this is similar to the notion of "0 dB" on a record level meter.
In any event, you may choose either system depending on which one makes the most
sense to you personally.
Dolby/DTS setup The SSP-600 incorporates both Dolby Pro Logic II and DTS Neo:6 technologies for
converting a two-channel signal into an enjoyable multichannel listening experience.
While they differ 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 multichannel system, so as to
simulate a discrete multichannel recording. Each has one or more adjustments available
to let you customize the performance of the processing to best suit your personal
preferences.
Dolby Pro Logic II Dolby Pro Logic II has three user-adjustable parameters.
Panorama is a simple on/off toggle (highlighted means "on") that will present a wider
and deeper front soundstage. This effect is somewhat signal-dependant, meaning that
it is more pronounced with some recordings and less so with others. With a good
recording, however, the effect an be quite dramatic.
