Direct Stream Digital (DSD) technology stores audio signals on digital 

storage media, such as Super Audio CDs. Using DSD, signals are stored as 

single bit values at a high-frequency sampling rate of 2.8224 MHz, while 

noise shaping and oversampling are used to reduce distortion, a common 

occurrence with very high quantization of audio signals. Due to the high 

sampling rate, better audio quality can be achieved than that offered by the 

PCM format used for normal audio CDs. The frequency is equal to or 

higher than 100 kHz, with a dynamic range of 120 dB. This unit can 

transmit or receive DSD signals via the HDMI jack.

This channel reproduces low-frequency bass signals, and has a frequency 

range from 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-channels in Dolby Digital or DTS 5.1-channel systems.

Neo:6 decodes the conventional 2-channel sources for 6-channel playback 

by the specific decoder. It enables playback with the full-range channels 

with higher separation just like digital discrete signal playback. There are 

two modes available: “Music mode” for music sources and “Cinema mode” 

for movie sources.

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. 

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 

accuracy 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, whereas 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 accurately the sound level can be reproduced.

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 designed for acoustic effects. Since home conditions, such as 

room size, wall material, number of speakers, and so on, can differ so 

widely, it is inevitable that there are differences in the sound that is heard. 

Based on a wealth of actually measured data, Yamaha CINEMA DSP uses 

Yamaha’s original DSP technology to combine Dolby Pro Logic, Dolby 

Digital, and DTS systems to provide the audiovisual experience of a movie 

theater in the listening room of your own home.

The Compressed music enhancer feature of this unit enhances your 

listening experience by regenerating the missing harmonics in compression 

artifacts. As a result, it compensates for flattened complexity due to the loss 

of high-frequency fidelity as well as lack of bass due to the loss of low-

frequency bass, providing improved performance for the overall sound 

system.

Yamaha has developed a natural, realistic sound effect DSP algorithm for 

headphones. Parameters for headphones have been set for each sound field 

program, so that accurate representations of all the sound field programs 

can be enjoyed on headphones.

Yamaha has developed a Virtual CINEMA DSP algorithm that allows you 

to enjoy DSP surround effects even 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.

With the component video signal system, the video signal is separated into 

the Y signal for luminance and the P

B

 and P

R

 signals for chrominance. 

Color can be reproduced more faithfully with this system because each of 

these signals is independent. The component signal is also called the “color 

difference signal” because the luminance signal is subtracted from the color 

signal. A monitor with component input jacks is required in order to output 

component signals.

With the composite video signal system, the video signal comprises the 

three basic elements of a video picture: color, brightness and 

synchronization data. A composite video jack on a video component 

transmits these three elements combined.

Deep Color refers to the use of various color depths in displays, up from the 

24-bit depths in previous versions of the HDMI specification. This extra bit 

depth allows HDTVs and other displays increase from millions of colors to 

billions of colors and eliminate on-screen color banding for smooth tonal 

transitions and subtle gradations between colors. The increased contrast 

ratio can represent many times more shades of gray between black and 

white. Additionally, Deep Color increases the number of available colors 

within the boundaries defined by the RGB or YCbCr color space.

HDMI (High-Definition Multimedia Interface) is the first industry 

supported, uncompressed, all-digital audio/video interface. Providing an 

interface between any sources (such as set-top boxes or AV receivers) and 

audio/video monitors (such as digital televisions), HDMI supports 

standard, enhanced or high-definition video as well as multichannel digital 

audio using a single cable. HDMI transmits all ATSC HDTV standards and 

supports 8-channel digital audio, with bandwidth to spare to accommodate 

future enhancements and requirements. 

When used in combination with HDCP (High-bandwidth Digital Content 

Protection), HDMI provides a secure audio/video interface that meets the 

security requirements of content providers and system operators. For 

further information on HDMI, visit the HDMI website at “http://

www.hdmi.org/.”

A color space standard supported by HDMI version 1.3. It is a more 

extensive color space than sRGB, and allows the expression of colors that 

were not hitherto possible. While remaining compatible with the color 

gamut of sRGB standards, “x.v.Color” expands the color space, and can 

thus produce more vivid, natural images. It is particularly effective for still 

pictures and computer graphics.
