Dolby Digital Plus is an advanced audio technology 
developed for high-definition programming and media 
including HD broadcasts, HD DVD, and Blu-ray Disc. 
Selected as a mandatory audio standard for HD DVD and 
as an optional audio standard for Blu-ray Disc, this 
technology delivers multichannel sound with discrete 
channel output. Supporting bitrates up to 6.0 Mbps, Dolby 
Digital Plus can carry up to 7.1 discreet audio channels 
simultaneously. Supported by HDMI version 1.3 and 
designed for the optical disc players and AV receivers/
amplifiers of the future, Dolby Digital Plus also remains 
fully compatible with the existing multichannel audio 
systems that incorporate Dolby Digital.

Dolby Pro Logic II is an improved technique used to 
decode vast numbers of existing Dolby Surround sources. 
This new technology enables a discrete 5-channel 
playback with 2 front left and right channels, 1 center 
channel, and 2 surround left and right channels instead of 
only 1 surround channel for conventional Pro Logic 
technology. There are three modes available: “Music 
mode” for music sources, “Movie mode” for movie 
sources and “Game mode” for game sources.

Dolby Pro Logic IIx is a new technology enabling discrete 
multi-channel playback from 2-channel or multi-channel 
sources. There are three modes available: “Music mode” 
for music sources, “Movie mode” for movie sources (for 
2-channel sources only) and “Game mode” for game 
sources.

Dolby Surround uses a 4-channel analog recording system 
to reproduce realistic and dynamic sound effects: 2 front 
left and right channels (stereo), a center channel for dialog 
(monaural), and a surround channel for special sound 
effects (monaural). The surround channel reproduces 
sound within a narrow frequency range. Dolby Surround is 
widely used with nearly all video tapes and laser discs, 
and in many TV and cable broadcasts as well. The Dolby 
Pro Logic decoder built into this unit employs a digital 
signal processing system that automatically stabilizes the 
volume on each channel to enhance moving sound effects 
and directionality.

Dolby TrueHD is an advanced lossless audio technology 
developed for high-definition disc-based media including 
HD DVD and Blu-ray Disc. Selected as a mandatory 
audio standard for HD DVD and 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 18.0 Mbps, Dolby TrueHD can carry up to 8 
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, Dolby TrueHD also remains fully compatible with 
the existing multichannel audio systems and retains the 
metadata capability of Dolby Digital, allowing dialog 
normalization and dynamic range control.

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.

DTS 96/24 offers an unprecedented level of audio quality 
for multi-channel sound on DVD video, and is fully 
backward-compatible with all DTS decoders. “96” refers 
to a 96 kHz sampling rate compared to the typical 48 kHz 
sampling rate. “24” refers to 24-bit word length. 
DTS 96/24 offers sound quality transparent to the original 
96/24 master, and 96/24 5.1-channel sound with full-
quality full-motion video for music programs and motion 
picture soundtracks on DVD video.

DTS digital surround was developed to replace the analog 
soundtracks of movies with a 6.1-channel digital sound 
track, and is now rapidly gaining popularity in movie 
theaters around the world. DTS, Inc. has developed a 
home theater system so that you can enjoy the depth of 
sound and natural spatial representation of DTS digital 
surround in your home. This system produces practically 
distortion-free 6-channel sound (technically, front left and 
right, center, surround left and right, and LFE 0.1 
(subwoofer) channels for a total of 5.1 channels). This unit 
incorporates a DTS-ES decoder that enables 6.1-channel 
reproduction by adding the surround back channel to the 
existing 5.1-channel format.
