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
previous Dolby surround, Dolby Digital provides even better sound
quality, greater spatial accuracy, and improved dynamic range.
Although a full set of speakers (front left, right, and center, surround
left and right, and a subwoofer) is required for true 5.1 channel Dolby
Digital surround sound, this receiver lets you enjoy Dolby Digital (and
Dolby Surround) program sources, even if you connect only the front
speakers.
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-
channel 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, Left Surround,
Right Surround, and Back Surround, 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 a full set of speakers (front left, right, and center, surround
left and right, surround back left and right and a subwoofer) is required
for true 6.1 channel Dolby Digital Surround EX sound, this receiver
lets you enjoy Dolby Digital (and Dolby Surround) program sources,
even if you connect only the front speakers.
Although only 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
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. The PRO LOGIC II modes
programmed into this receiver are “MOVIE”, “MUSIC” and “PRO
LOGIC”. The “MOVIE” mode of the PRO LOGIC II has preset
characteristics to produce a calibrated, high-level surround sound
playback while the “MUSIC” mode has user-adjustable characteris-
tics to offer the three optional controls, like “Dimension”, “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 adjustment of the
left-center-right speakers’ balance; the “Panorama” mode extends
the front stereo image to include the surround speakers for an
exciting “wraparound” effect with side wall imaging.
DTS
DTS (Digital Theater System) is a 5.1 channel digital audio format that
provides five full spectrum channels and one low-frequency
(subwoofer) channel for unprecedented clarity, optimum channel
seperation and a (wide) dynamic range.
In the DTS mode, the 5.1 channel digital input from a DTS CD, LD or
DVD disc (carrying the "DTS" marking) can be played in Digital
Surround.
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 produce 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 surround
channels using matrix technology. DTS-ES has perfect compatibility
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 mode, "CINEMA" mode is for
movie playback and "MUSIC" mode is for music playback.
DTS has a .1 or LFE channel.
The indication “LFE” appears in the display when a signal is being
input for this channel.
Note
LFE = Low Frequency Effects. This channel delivers separate non-
directional bass signals to the subwoofer for more dynamic deep
bass sound effects.
DVD 6-channel mode
Using a DVD player or the like equipped with six (5.1) output channels
and the receiver, you can enjoy multi-channel encoded DVD source
material in all its splendor. Since the source signals are digital and
each channel is input independently, the resulting sound quality,
sense of spaciousness, and dynamic range are superb.
The indication “LFE” appears in the display during DVD 6-channel
mode selection.
