GLOSSARY
■ Neo:6
Neo:6 decodes conventional 2-channel sources for
6 channel playback by. It enables playback with the full-
range channels with higher separation comparable to
digital discrete signal playback. Two modes are available;
"Music mode" for playing music sources and "Cinema
mode" for movies.
■ PCM (Linear PCM)
Linear PCM is a signal format under which an analog
audio signal is digitized, recorded and transmitted without
using any compression. This is used as a method of
recording CDs and DVD audio. The PCM system uses a
technique for sampling the size of the analog signal per
very small unit of time. Standing for "pulse code
modulation", the analog signal is encoded as pulses and
then modulated for recording.
■ SRS CS
(SRS Circle Surround )
(U.S.A. model only)
SRS CS (SRS Circle Surround ) is a
high-performance 6.1 channel matrix surround sound
decoding system. It is the next-generation of the original
SRS Circle Surround technology, incorporating powerful
industry-first features including the dialog clarity
enhancement technology and added cinema-like bass to
the front channels and subwoofer.

Sound field programs

■ CINEMA DSP
Since the Dolby Surround and DTS systems were
originally designed for use in movie theaters, their effect
is best felt in a theater having many speakers and designed
for acoustic effects. Since home conditions, such as room
size, wall material, number of speakers, and so on, can
differ so widely, it's inevitable that there are differences in
the sound heard. Based on a wealth of actually measured
data, YAMAHA CINEMA DSP uses YAMAHA original
sound field technology to combine Dolby Pro Logic,
Dolby Digital and DTS systems to provide the visual and
audio experience of a movie theater in the listening room
of your own home.
■ SILENT CINEMA
YAMAHA has developed a natural, realistic sound effect
DSP algorithm for headphones.
Parameters for headphones have been set for each sound
field so that accurate representations of all the sound field
programs can be enjoyed on headphones.
■ Virtual CINEMA DSP
YAMAHA has developed a Virtual CINEMA DSP
algorithm that allows you to enjoy DSP sound field
surround effects without any surround speakers by using
virtual surround speakers.
It is even possible to enjoy Virtual CINEMA DSP using a
minimal two-speaker system that does not include a center
speaker.

Audio information

■ ASA (Advanced Speaker Array)
ASA is a proprietary THX technology which processes
the sound fed to 2 side and 2 back surround speakers to
provide the optimal surround sound experience. When you
set up your home theater system using all eight speaker
outputs (Left, Center, Right, Surround Right, Surround
Back Right, Surround Back Left, Surround Left and
Subwoofer) placing the two Surround Back speakers close
together facing the front of the room will provide the
largest sweet spot. If for practical reasons you have to
place the Surround Back speakers apart, you will need to
go THX Audio Set-up screen and choose the setting that
most closely corresponds to the speaker spacing, which
will re-optimized the surround sound-field.
ASA is used in three new modes: THX Select2 Cinema,
THX Music Mode and THX Games Mode.
■ ITU-R
ITU-R is the radio communication sector of the ITU
(International Telecommunication Union). ITU-R
recommends a standard speaker placement which is used
in many critical listening rooms, such as mastering
studios.
■ LFE 0.1 channel
This channel is for the reproduction of low bass signals.
The frequency range for this channel is 20 Hz to 120 Hz.
This channel is counted as 0.1 because it only enforces a
low frequency range compared to the full-range
reproduced by the other 5/6 channels in Dolby Digital or
DTS 5.1/6.1-channel systems.
■ Sampling frequency and number of
quantized bits
When digitizing an analog audio signal, the number of
times the signal is sampled per second is called the
sampling frequency, while the degree of fineness when
converting the sound level into a numeric value is called
the number of quantized bits.
The range of rates that can be played back is determined
based on the sampling rate, while the dynamic range
representing the sound level difference is determined by
the number of quantized bits. In principle, the higher the
sampling frequency, the wider the range of frequencies
that can be played back, and the higher the number of
quantized bits, the more finely the sound level can be
reproduced.
