Dolby Digital EX
Dolby Digital EX is a 6.1-channel surround format
proposed by Dolby Laboratories that allows users
to enjoy in their homes the “DOLBY DIGITAL
SURROUND EX” audio format jointly developed by
Dolby Laboratories and Lucas Films.
The 6.1 channels of sound, including surround back
channels, provide improved sound positioning and
expression of space.
Dolby Digital Plus
Dolby Digital Plus is an improved Dolby Digital signal
format that is compatible with up to 7.1 channels
of discrete digital sound and also improves sound
quality thanks to extra data bit rate performance.
It is upwardly compatible with conventional Dolby
Digital, so it offers greater flexibility in response to
the source signal and the conditions of the playback
equipment.
Dolby TrueHD
Dolby TrueHD is a high definition audio technology
developed by Dolby Laboratories, using lossless
coding technology to faithfully reproduce the sound
of the studio master.
This format provides the facility to support up to
8 audio channels with a sampling frequency of
96kHz/24bit resolution and up to 6 audio channels
with a sampling frequency of 192kHz/24bit
resolution. Dolby TrueHD is adopted for applications
that put very high importance on sound quality.
Dolby Pro Logic g
Dolby Pro Logic g is a matrix decoding technology
developed by Dolby Laboratories.
Regular music such as that on CDs is encoded into
5 channels to achieve an excellent surround effect.
The surround channel signals are converted into
stereo and full band signals (with a frequency
response of 20 Hz to 20 kHz or greater) to create
a “three-dimensional” sound image offering a rich
sense of presence for all stereo sources.
Dolby Pro Logic gx
Dolby Pro Logic gx is a further improved version of
the Dolby Pro Logic g matrix decoding technology.
Audio signals recorded in 2 channels are decoded
to achieve a natural sound with up to 7.1 channels.
There are three modes: “Music” suited for playing
music, “Cinema” suited for playing movies, and
“Game” which is optimized for playing games.
Explanation of terms
Dolby Pro Logic gz
Dolby Pro Logic gz introduces a new dimension to
Home Entertainment through the addition of a pair
of front height channels. Compatible with stereo,
5.1-channel and 7.1-channel content, Dolby Pro
Logic gz provides enhanced spaciousness, depth
and dimension to movies, concert video and video
game playback while maintaining the full integrity
of the source mix.
Dolby Pro Logic gz identifies and decodes spatial
cues that occur naturally in all content, directing
this information to the front height channels,
complementing the performance of left and right
surround sound speakers. Content that is encoded
with Dolby Pro Logic gz height channel information
can be even more revealing, with perceptually
discrete height channel information bringing an
exciting new dimension to home entertainment.
Dolby Pro Logic gz, with front height channels is
also an ideal alternative for households that cannot
support the placement of back surround speakers
of a typical 7.1-channel system but may have
bookshelf space available to support the addition of
height speakers.
Dolby Volume
Automatically adjusts the volume that varies
depending on the contents and input source and
performs appropriate corrections of the frequency
characteristic.
Downmix
This function converts the number of channels of
surround audio to less number of channels and
plays back.
DTS
This is an abbreviation of Digital Theater System,
which is a digital audio system developed by DTS.
When playing back audio by connecting this system
with a device such as DTS amplifier, accurate sound
field position and realistic sound effect as if you are
in a movie theater can be obtained.
DTS 96/24
DTS 96/24 is a digital audio format enabling high
sound quality playback in 5.1 channels with a
sampling frequency of 96 kHz and 24 bit quantization
on DVD-Video.
DTS Digital Surround

format of DTS, Inc., compatible with a sampling
frequency of 44.1 or 48 kHz and up to 5.1 channels
of digital discrete surround sound.
DTS-ES™ Discrete 6.1
DTS-ES™ Discrete 6.1 is a 6.1-channel discrete
digital audio format adding a surround back (SB)
channel to the DTS digital surround sound.
Decoding of conventional 5.1-channel audio signals
is also possible according to the decoder.
DTS-ES™ Matrix 6.1
DTS-ES™ Matrix 6.1 is a 6.1-channel discrete digital
audio format inserting a surround back (SB) channel
to the DTS digital surround sound through matrix
encoding. Decoding of conventional 5.1-channel
audio signals is also possible according to the
decoder.
DTS Express
DTS Express is an audio format supporting low bit
rates (max. 5.1 channels, 24 to 256 kbps).
DTS-HD
This audio technology provides higher sound quality
and enhanced functionality than the conventional
DTS and is adopted as an optional audio for Blu-ray
Disc. This technology supports multi-channel, high
data transfer speed, high sampling frequency, and
lossless audio playback. Maximum 7.1-channels are
supported in Blu-ray Disc.
DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is an improved
version of the conventional DTS, DTS-ES and
DTS 96/24 signals formats, compatible with
sampling frequencies of 96 or 48 kHz and up to
7.1 channels of discrete digital sound. High data
bit rate performance provides high quality sound.
This format is fully compatible with conventional
products, including conventional DTS digital
surround 5.1-channel data.
DTS-HD Master Audio
DTS-HD Master Audio is a lossless audio format
created by Digital Theater System (DTS). This
format provides the facility to support up to 8 audio

Cinema” suited for playing movies and “DTS
NEO:6 Music” suited for playing music.
Dynamic range
The difference between the maximum undistorted
sound level and the minimum discernible level
above the noise emitted by the device.
H
HDCD
HDCD
®
is an encoding/decoding technology that
greatly reduces the distortion that occurs upon
digital recording while maintaining compatibility
with the conventional CD format, thus expanding
the dynamic range and achieving a high resolution.
Conventional CDs and HDCD compatible CDs are
identified automatically to select the optimum
digital processing.
HDCP
When transmitting digital signals between devices,
this copyright protection technology encrypts
the signals to prevent content from being copied
without authorization.
HDMI
This is an abbreviation of High-Definition Multimedia
Interface, which is an AV digital interface that can
be connected to a TV or amplifier. Video signal and
audio signal can be connected using 1 cable.

bass.
M
MAIN ZONE
The room where this unit is placed is called the
MAIN ZONE .
MP3 (MPEG Audio Layer-3)
