CINEMA DSP
■ Dolby Surround
Dolby Surround uses four discrete channels and five
speakers to reproduce realistic and dynamic sound effects:
two main channels (left and right), a center channel for
dialog, and a rear channel for special sound effects. The rear
channel reproduces sound within a narrow frequency range.
Most video tapes and laser discs include Dolby Surround
encoding, as do many TV and cable broadcasts. The Dolby
Pro Logic decoder built into this unit employs a digital
signal processing system that stabilizes each channel for
even more accurate sound positioning than is available with
standard analog processors.
■ Dolby Digital
Dolby Digital is a digital surround sound system that
provides completely independent multi-channel audio to
you. Dolby Digital provides five full-range channels in what
is sometimes referred to as a “3/2” configuration: three front
channels (left, center and right), and two surround channels.
A sixth bass-only effect channel is also provided for output
of LFE (low frequency effect), or low bass effects that are
independent of other channels. (This is called the “LFE
channel”.) This channel is counted as 0.1, thus giving rise to
the term 5.1 channels in total.
The wide dynamic range of sound reproduced by the five
full-range channels and precise sound orientation by digital
sound processing provides listeners with excitement and
realism that have never been experienced before.
■ CINEMA DSP
The Dolby Surround and Dolby Digital sound systems show
their full ability in a large movie theater, because movie
sounds are originally designed to be reproduced in a large
movie theater that uses a multitude of speakers. Trying to
create a sound environment similar to that of a movie theater
in your home is difficult because of the room size, material
inside the walls, the number of speakers, and so on. In other
words, your listening room is very different from a movie
theater.
However, YAMAHA DSP technology allows you to create
nearly the same sound experience as that of a large movie
theater in your home by compensating for the lack of
presence and dynamics in the listening room with original
digital sound fields combined with Dolby Surround or
Dolby Digital.
The YAMAHA “CINEMA DSP” logo indicates those
programs that are created by the combination of YAMAHA
DSP technology and Dolby Surround or Dolby Digital.
■ LFE 0.1 Channel
This channel is for reproduction of low bass signals. The
frequency range for this channel is 20 Hz to 120 Hz. This
channel is called the channel 0.1 because it only reproduces
a low frequency range compared to the full-range from
20 Hz to 20 kHz that is reproduced by the 5 channels in a
Dolby Digital 5.1 channel system.
