Dolby Pro Logic IIx
Dolby Pro Logic IIx transforms any stereo or 5.1-channel signal
into six- or seven-channel, full range surround sound, creating a
seamless, natural surround soundfield that immerses you in the
entertainment experience.
Three listening modes, Movie, Music or Game allow you to tailor
the audio to meet the different needs of the programming. In
Game mode, for instance, special effects signals are routed to
the surround channels for fuller, dramatic impact. Music mode
features three additional use controls:
• Dolby Center Width adjusts the balance of the main vocals in
the center and front channels.
• Dolby Panorama creates a seamless, wraparound surround
effect.
• Dolby Dimension lets you set a deeper or shallower surround
soundfield.
DTS
DTS Digital Surround is the standard for providing 5.1 channels
of discrete digital audio in consumer electronics products and
software content.
DTS can contain a larger volume of data than Dolby Digital, and
can reproduce high quality surround sound. They are the same
as the Dolby Digital 5.1 channels, but it is a format that lowered
the audio compression rate when recording digitally. Because of
that, rich sound with high S/N can be reproduced. Moreover, an
exact, magnificent surround sound with wide dynamic range and
excelling in separation is a feature of DTS.
DTS has a ".1" or LFE channel.
The indication "LFE" appears in the display when a signal is being
input for this channel.
DTS-ES
In the cinema, the center surround channel is not discrete,
but is matrixed into the left surround (LS) and right surround
(RS) channels. Embedded in the soundtrack print master, this
matrixed channel works with all cinema digital sound formats.
DTS calls this process Extended Surround, or "ES".
Neo:6
Neo:6 provides up to six full-band channels of matrix decoding
from stereo matrix material. Users with 6.1 and 5.1 systems will
derive six and five separate channels, respectively, corresponding
to the standard home theater speaker layouts. (The ".1"
subwoofer channel is generated by bass management in the
receiver.)
Neo:6 provides optimum decoding of Extended Surround matrix
soundtracks, and can also generate a center surround channel
from 5.1 material.
Neo:6 technology allows various sound elements within a
channel of channels to be steered separately, and in a way which
follows the original presentation naturally.
Neo:6 offers a music mode that expands stereo non-matrix
recordings into the five- or six-channel layout without
diminishing the subtlety and integrity of the original stereo
recording.
Dolby Digital
Dolby Digital is a highly sophisticated and versatile audio
encoding/decoding technology. Dolby Digital technology can
transmit mono, stereo (two-channel), or up to 5.1-channel
surround sound (discrete* multichannel audio).
In 5.1-channel surround sound, the three front channels
(Left/Center/Right) deliver crisp, clean dialogue and accurate
placement of on-screen sounds, while twin surround channels
(Left Surround/Right Surround) wrap around the audience and
immerse them in the action. The LFE (Low-Frequency Effects)
channel delivers real impact for explosions and other effects that
can, literally, be felt as well as heard.
The superior coding efficiency of Dolby Digital-and its ability
to deliver high-quality discrete multichannel audio without
compromising video quality has made it the designated audio
standard for DVD worldwide.
* The sound information contained in each of the six available
channels is distinct and independent. These six channels
are described as a "5.1-channel" system, because there are
five full-bandwidth channels with 3 Hz to 20 kHz frequency
range for Front Left and Right, Center, and Surround, plus one
"Low Frequency Effects" (LFE) subwoofer channel devoted to
frequencies from 3 to 120 Hz.
Dolby Digital EX
Dolby Digital EX takes the Dolby Digital 5.1-channel setup
one step further with an additional center surround channel
(reproduced through one or two speakers) for extra dimensional
detail and an enveloping surround sound effect.
Feature films originally released in Dolby Digital Surround EX
(the cinema version) carry the encoded extra surround channel
in their subsequent DVD releases, as well as onto 5.1-channel
digital satellite and TV broadcasts. With this receiver, you can hear
Surround EX soundtracks as they were meant to be heard, with
the increased realism created by the extra surround channel.
Dolby Pro Logic II
Dolby® Pro Logic® II technology processes any high quality stereo
(two-channel) movie and music audio into five playback channels
of full-bandwidth surround sound. A matrix surround decoding
technology, Dolby Pro Logic II detects the directional cues that
occur naturally in stereo content and uses these elements to
create a five-channel surround sound playback experience.
Dolby Pro Logic II is fully compatible with all Dolby Pro Logic
technologies. It provides optimal audio for playback in a 5.1-
channel home theater system for the thousands of videocassettes
and TV programs encoded in four-channel Dolby Surround (the
encoding counterpart to Dolby Pro Logic's decoding technology).
(Dolby Pro Logic II surround Movie mode)
Dolby Pro Logic II also enables video game consoles to encode
five-channel surround sound information into a stereo signal
with virtually no impact on the console's CPU, which means all
this extra audio won't slow your game down. (Dolby Pro Logic II

Dolby Pro Logic II can bring new life to your CD collection. Play
your music through your home theater system, and you'll hear
seamless, natural sound with new depth and detail. It's almost
like hearing a newly remastered CD. (Dolby Pro Logic II surround
