■ 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  )

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.

■ 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.

■ 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 

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.
