Ambience effects
Dolby Digital
The Dolby Digital surround format lets you enjoy up to 5.1 channels
of digital surround sound from Dolby Digital program sources (such as
Laserdisc or DVD software marked
). Compared with previ-
ous Dolby surround, Dolby Digital provides even better sound quality,
greater spatial accuracy, and improved dynamic range.
Dolby Digital EX
Dolby Digital EX is an extension of Dolby Digital technology, Dolby
Digital EX creates six full-bandwidth output channels from 6.1-chan-
nel sources. This is done using a matrix decoder that derives three
surround channels from the two in the original recording.
This is achieved by using three different surround signals, surround
left, surround right, and surround back, each driving its own array of
speakers. Think of it as adding a center channel for the rear speakers,
which give more diffuse and natural surround effect, even if you
wanted the ability to completely encircle the audience with sound,
positioning sound effects exactly where they would be heard in real
life. For best results, Dolby Digital EX should be used with movie
soundtracks recorded with Dolby Digital Surround EX which contain
a digital flag that will automatically activate this feature. However, for
titles released prior to late 2001, this feature has to be activated
manually.
Although Dolby Digital soundtracks incorporate a separate low
frequency channel, connecting a subwoofer will also improve deep
bass performance in the other surround modes.
The indication “LFE” appears in the display when a signal is being
input for this channel.
Dolby Pro Logic II x and Dolby Pro Logic II
Dolby Pro Logic II was designed specifically to provide a new sense
of spatiality, directionality and articulation of sounds from Dolby
Surround encoded sources (such as video and Laserdisc software
marked
). This is achieved with an intelligent, built-in
feedback logic design, a matrix surround decoding and the decoding
of stereo, full bandwidth surround outputs.
Dolby Pro Logic IIx enhanced Dolby Pro Logic II’s features.
It creates 6.1 channel and 7.1 channel surround sound from stereo or
5.1 channel signals. This feature provides you an astonishing ambi-
ence effect which makes you feel you are surrounded by natural
sound. Especially 7.1 channel surround sound can produce real back
sound from Surround Back speakers.
The Pro Logic IIx modes programmed into this model are “Movie”,
“Music” and “Game”. The Pro Logic II modes programmed into this
model are “Movie”, “Music”, “Game” and “Pro Logic”. The “Movie”
mode has preset characteristics to produce a calibrated, high-level
surround sound playback while the “Music” mode has user-adjust-
able characteristics to offer the three optional controls, like “Dimen-
sion”, “Center Width” and “Panorama” modes to allow optimization
of the soundfields as desired. The “Dimension” control allows the
user to gradually adjust the soundfield either towards the front or
towards the rear; the “Center Width” control allows various adjust-
ment of the left-center-right speakers’ balance; the “Panorama”
mode extends the front stereo image to include the surround speak-
ers for an exciting “wraparound” effect with side wall imaging.
The “Game” mode provides surrounded and exciting sound when
you enjoy game or TV. Especially in Pro Logic IIx “Game” mode, base
sound not only from Front and Center but also from Surround channel
is added to Subwoofer. This provides ever more dynamic surround
effects.
DTS
The DTS multi-channel audio format is available on CD, LD and DVD
software. DTS is a strictly digital format and cannot be decoded inside
most CD, LD or DVD players. For this reason, if you attempt to listen
to DTS encoded software through the analog output of your new CD,
LD or DVD player, you will experience digital noise in most cases. This
noise can be quite loud if the analog output is connected directly to a
high power amplification system. Proper measures for playing the
digital output as described below should be taken to avoid this
situation. To enjoy DTS Digital Surround playback, an external 5.1
channel DTS Digital Surround decoder system or an amplifier with a
built-in DTS Digital Surround decoder must be connected to the digital
output (S/P DIF, AES/EBU or TosLink) of a CD, LD or DVD player.
All models are incorporated with the DTS decoder.
DTS-ES
DTS-ES (Digital Theater System-Extended Surround) presents 6.1
channels surround system with additional Surround Back channel
which evolved from the conventional 5.1 channels surround system.
DTS-ES format that was recorded in DVD, CD or LD comprises of two
modes. DTS-ES Discrete 6.1 produces the discrete surround back
which is completely independent and DTS-ES Matrix 6.1 produces
the surround back which synthesised within the left and right sur-
round channels using matrix technology. DTS-ES has perfect compat-
ibility with the conventional 5.1 channels surround system. 6.1
channels surround with an additional surround back presents a more
natural presence and surround effects by increasing the impression
of the sound image from back. Programs which are recorded using
DTS-ES technology consist of information flags which will be able to
control the Discrete and Matrix mode. Thus, it can automatically
select the best matched mode.
Neo:6
Neo:6 is a new technology which was developed by DTS. It can
produce high grade 6 channels surround with an astonishing fidelity
from 2 channels content. Neo:6 has 2 modes, “Cinema” mode is for
movie playback and “Music” mode is for music playback.
DTS 96/24
DTS 96/24 made it possible to achieve a wide frequency range of over
40 kHz by increasing the sampling frequency to 96 or 88.2 kHz.
Moreover, DTS 96/24’s ability of 24 bit resolution offers the same
frequency band and dynamic range as 96 kHz/24 bit PCM.
DTS 96/24 is, as with conventional DTS Surround, compatible with
multi-channels. Therefore, sources recorded using DTS 96/24 tech-
nologies can be played in high sampling frequency, multichannel
audio with ordinary DVDs and CDs.
DTS has a “.1” or “LFE” channel.
The indication “LFE” appears in the display when a signal is being
input for this channel.
Dolby Virtual Speaker
The Dolby Virtual Speaker features a virtual surround sound field.
This implements an effect as if there are multiple speakers in the
listening room.
Dolby Headphone
When headphones are used in music listening, the audio of the left
(or right) channel reaches only the left (or right) ear so the listener
cannot feel the presence of acoustic images on the front.
The Dolby Headphone simulates a virtual room and include its
acoustic characteristics in the left and right headphone signals. As a
result, the listener can hear the same components as in speaker
listening through the left and right years and therefore feel as if the
sound source is located on the front of the listener.
Because of the same processing in "Pro Logic II Movie mode with
Dolby Headphone" and "Pro Logic II Game mode with Dolby Head-
phone", their respective effectiveness is the same.
Note
LFE = Low Frequency Effects. This channel delivers separate non-
directional bass signals to the subwoofer for more dynamic deep
bass sound effects.
DSP mode
The DSP mode lets you add the atmosphere of a live concert or hall
to almost any type of program source. The way a sound is heard in an
actual environment depends on a variety of different factors. One of
the most important is reverberation (the act of decaying elements of
sound echoing in various places).
The DSP modes produce the feeling of presence by using the DSP to
create reverberation, without spoiling the sound quality of the original
signal. These modes are particularly effective when used with stereo
program sources, like CD, television, and FM radio. You might enjoy
trying the Arena, Jazz Club, Theater, Stadium or Disco mode the next
time you watch a concert or sporting event!
