Audio formats/Decoding
Dolby
The Dolby technologies are explained below. See http://www.dolby.com for more detailed information.
Dolby Digital
Dolby Digital is a multichannel digital audio coding system widely used in cinemas, and in the home for DVD and
digital broadcast soundtracks.
Dolby TrueHD
Dolby TrueHD is the lossless encoding technology developed for high-definition optical discs in the upcoming
era.
Dolby Digital Plus
Dolby Digital Plus is the audio technology for all high-definition programming and media. It combines the effi-
ciency to meet future broadcast demands with the power and flexibility to realize the full audio potential expected
in the upcoming high-definition era.
Dolby Digital Surround EX
Dolby Digital Surround EX (the EX stands for EXtended) is an extension of Dolby Digital encoding whereby a
surround back channel is matrixed into the surround left/right channels for 6.1 channel playback. This allows for
compatibility with Dolby Digital 5.1 channel decoding, as well as for decoding using Dolby Digital EX.
Dolby Pro Logic IIx and Dolby Surround
Dolby Pro Logic IIx is an improved version of the Dolby Pro Logic II (and Dolby Pro Logic) decoding system.
Dolby Surround is an encoding system which embeds surround sound information within a stereo soundtrack,
which a Dolby Pro Logic decoder can then use for enhanced surround listening with greater sound detail.
Dolby Pro Logic IIz
Adding a pair of speakers above the front left and right speakers adds expressiveness in the vertical direction to
the previous horizontally-oriented sound field. The height channel strengthens the sound field’s sense of three-
dimensionality and air, producing presence and expansion.
DTS
The DTS technologies are explained below. See http://www.dts.com for more detailed information.
DTS Digital Surround
DTS Digital Surround is a 5.1-channel audio coding system from DTS Inc. now widely used for DVD-Video, DVD-
Audio, 5.1 music discs, digital broadcasts, and video games.
DTS-HD Master Audio
DTS-HD Master Audio is a technology that delivers master audio sources recorded in a professional studio to
listeners without any loss of data, preserving audio quality.
DTS-HD High Resolution Audio
A high definition audio technology by which signals can be transferred over HDMI cables.
DTS-ES
DTS-ES (the ES stands for Extended Surround) is a decoder that is capable of decoding both DTS-ES Discrete 6.1
and DTS-ES Matrix 6.1 encoded sources.
DTS Neo:X
DTS Neo:X can generate 11.1 channel surround sound from any matrixed stereo source (such as video or TV) and
from 5.1 channel sources.
THX
The THX technologies are explained below.
See http://www.thx.com for more detailed information.
THX Cinema
A mode for playing in a home theater environment the sound tracks of theater movies that have been recorded
and edited for playback in large spaces such as movie theaters.
THX Music
A mode adjusted mainly for listening to music that has been masterized at a higher level than movie sound
tracks.
THX Games
A mode for playing the sound of games with spatial fidelity. In many cases the sound is mixed in the same way as
for movies, but this mode is meant for small environments rather than the large environments of theaters.
THX Surround EX
A mode using technology developed jointly by Dolby Laboratories and THX for creating a sound field behind the
listeners.
THX Loudness Plus
A mode creating a rich, subtle surround sound field through optimal calibration of the volume and frequency
response of the individual channels according to the volume level.
Decoding
A technology for converting digital signals that have been compressed upon recording by a digital signal process-
ing circuit, etc., into the original signals. The term “decoding” (or “matrix decoding”) is also used for the technol-
ogy which converts 2-channel sound sources into multiple channels or expands 5.1-channel signals into 6.1 or
7.1 channels.
Calibrating the sound field/Improving the sound quality
Phase Control
The Phase Control technology incorporated into this receiver’s design provides coherent sound reproduction
through the use of phase matching for an optimal sound image at your listening position.
Full Band Phase Control
The Full Band Phase Control feature calibrates the frequency-phase characteristics of the speakers connected.
Virtual Surround Back
When you’re not using surround back speakers, selecting this mode allows you to hear a virtual surround back
channel through your surround speakers. You can choose to listen to sources with no surround back channel
information.
Virtual Height
When you’re not using front height speakers, selecting this mode allows you to hear a virtual front height channel
through your front speakers.
Virtual Wide
When you’re not using front wide speakers, selecting this mode allows you to hear a virtual front wide channel
through your front speakers.
Virtual Depth
When this mode is selected, the sound field expands virtually to behind the display, resulting in a sound field with
the same depth as the 3D picture to achieve a better sense of presence.
