Yamaha rx-a3000 User Guide

DTS-HD Master Audio is an advanced lossless audio technology developed 

for high-definition disc-based media including Blu-ray Disc. Selected as an 

optional audio standard for Blu-ray Disc, this technology delivers sound 

that is bit-for-bit identical to the studio master, offering a high-definition 

home theater experience. 

Supporting bitrates up to 24.5 Mbps for Blu-ray Disc, DTS-HD Master 

Audio can carry up to 7.1 discrete channels of 24-bit/96 kHz audio 

simultaneously. Supported by HDMI version 1.3 and designed for the 

optical disc players and AV receivers/amplifiers of the future, DTS-HD 

Master Audio also remains fully compatible with the existing multichannel 

audio systems that incorporate DTS Digital Surround. 

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

by the specific decoder. It enables playback with the fullrange 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.

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 and the dynamic range is 120 dB. This unit can 

transmit or receive DSD signals input from the HDMI jack.

This is a file format for lossless audio data compression. FLAC is inferior 

to lossy compression formats in compression rate but provides higher audio 

quality.

One of the audio compression methods used by MPEG. It employs the 

irreversible compression method, which achieves a high compression rate 

by thinning out the data of hardly audible part to the human ears. It is said 

to be capable of compressing the data quantity by about 1/11 (128 kbps) 

while maintaining a similar audio quality to music CD.

An MPEG-4 audio standard. As it allows compression of data at a bit rate 

lower than that of MPEG-2 AAC, it is used among others for mobile 

telephones, portable audio players and other low-capacity devices requiring 

high sound quality. In addition to the above types of devices, MPEG-4 

AAC is also used to distribute contents on the Internet, and as such is 

supported by computers, media servers and many other devices.

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.

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 

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.

Windows standard audio file format, which defines the method of recording 

the digital data obtained by converting audio signals. It does not specify the 

compression (coding) method so a desired compression method can be used 

with it. By default, it is compatible with the PCM method (no compression) 

and some compression methods including the ADPCM method.

An audio compression method developed by Microsoft Corporation. It 

employs the irreversible compression method, which achieves a high 

compression rate by thinning out the data of hardly audible part to the 

human ears. It is said to be capable of compressing the data quantity by 

about 1/22 (64 kbps) while maintaining a similar audio quality to music 

CD.

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 actually measured sound field data contain the information of the 

height of the sound images. CINEMA DSP 3D feature achieves the 

reproduction of the accurate height of the sound images so that it creates 

the accurate and intensive stereoscopic sound fields in a listening room. 

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 

program, so that accurate representations of all the sound 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.
