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, 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 wolud 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 and right, center, surround
left and right, back surround and a subwoofer) are 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.
DTS-ES
DTS-ES (Digital Theater System-Extended Surround) presents 6.1
channels surround system with additional Back Surround channe
l
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 back surround
which is completely independent and DTS-ES Matrix 6.1 produces
the back surround 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 back surround presents a more natura
l
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 contro
l
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.
Ambience effects
DSP mode
The DSP mode lets you add the atmosphere of a live concert or hall
to almost any type of program source. 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!
What's DSP?
DSP stands for Digital Signal Processor.
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.
