Dolby Digital EX
Dolby Digital EX (DOLBY D EX) is a new digital surround
encoding format that adds the third surround channels, called
“surround back.”
Compared to the conventional Dolby Digital 5.1CH, the newly
added surround back channel can reproduce more detailed
movements behind you while viewing the video software. In
addition, surround sound localization will become more stable.
Dolby Pro Logic
Dolby Surround encoding format records the left front channel,
right front channel, center channel, and surround channel
(monaural) signals into 2 channels.
The Dolby Pro Logic (PRO LOGIC) built in this receiver decodes
these 2 channel signals into 4 original channel signals (plus
subwoofer)—matrix-based multi-channel reproduction.
• When Dolby Pro Logic is activated, the
indicator lights up
on the display.
• THX Cinema can be applied together with Pro Logic when an
analog or digital 2-channel software is played back.
Dolby Pro Logic II
Dolby Pro Logic II has a newly developed multi-channel
playback format to convert 2-channel software into 5-channel (plus
subwoofer). The matrix-based conversion method used for Dolby
Pro Logic II makes no limitation for the cutoff frequency of the
surround treble and enables stereo surround sound.
• This receiver provides two types of Dolby Pro Logic II modes—
Pro Logic II Movie (PLII MOVIE) and Pro Logic II Music
(PLII MUSIC).
When Dolby Pro Logic II is activated, the
indicator lights
up on the display.
Pro Logic II Movie : Suitable for playing any Dolby Surround
encoded software. You can enjoy a sound
field very close to the one created with
discrete 5.1-channel sounds.
Pro Logic II Music : Suitable for playing any 2-channel stereo
software. You can enjoy wide and deep
sounds.
• THX Cinema can be applied together with Pro Logic II Movie
when an analog or digital 2-channel software is played back.
DTS* 3
DTS is another digital signal compression method, developed by
Digital Theater Systems, Inc., and enables multi-channel encoding
and decoding (1ch up to 6.1ch).
• When a DTS signal is detected through the digital input,
the indicator lights up on the display.
DTS Digital Surround
DTS Digital Surround (DTS SURROUND) is another discrete
5.1 channel digital audio format available on CD, LD, and DVD
software.
Compared to Dolby Digital, the DTS Digital Surround format has
a lower audio compression rate which enables it to add breadth and
depth to the sounds reproduced. As such, DTS Digital Surround
features natural, solid and clear sound.
• When 7.1-channel reproduction mode (EX/ES/7.1) is set to
“ON,” DTS Neo:6 (DTS NEO:6) is applied while playing back
multi-channel DTS software. It creates the same surround
ambience as playing 6.1-channel software.
DTS Extended Surround (DTS-ES)
DTS-ES is another new multi-channel digital encoding format.
It greatly improves the 360-degree surround impression and space
expression by adding the third surround channel—surround back
channel.
DTS-ES includes two signal formats with different surround signal
recording methods—DTS-ES Discrete 6.1ch (DTS-ES DSCRT)
and DTS-ES Matrix 6.1ch (DTS-ES MATRIX).
DTS-ES Discrete 6.1ch has been designed to encode (and decode) a
6.1-channel signal discretely to avoid interference with each
channel.
DTS-ES Matrix 6.1ch has been designed to add an extra surround
channel to DTS Digital Surround 5.1-channel. By using a matrix
encoding/decoding method, an additional “surround back” channel
signal is encoded (and decoded) in both the left and right surround
channel signals.
DTS 96/24
In recent years, there has been increasing interest in higher sampling
rates both for recording and for reproducing at home. Higher
sampling rates allow wider frequency range and greater bit depths
provide extended dynamic range.
DTS 96/24 is a multi-channel digital signal format (fs 96 kHz/24
bits) introduced by Digital Theater Systems, Inc. to deliver “better-
than-CD sound quality” into the home.
• When DTS 96/24 signals are detected, the 96/24 indicator lights
up. You can enjoy its 5.1-channel sound with full-quality.
DTS Neo:6
DTS Neo:6 is a newly developed conversion method to create
6-channel (plus subwoofer) from analog/digital 2-channel software
and DTS Digital Surround software by using the high precision
digital matrix decoder used for DTS-ES Matrix 6.1ch.
• This receiver provides two types of DTS Neo:6 modes—Neo:6
Cinema (NEO:6 CINEMA) and Neo:6 Music (NEO:6 MUSIC).
When either Neo:6 mode is activated, the Neo:6 indicator lights
up on the display.
Neo:6 Cinema : Suitable for playing movies. You can get the same
atmosphere with 2-channel software as with 6.1-
channel software. It is also effective for playing
software encoded with conventional surround
formats.
Neo:6 Music : Suitable for playing music software. The front
channel signals bypass the decoder (resulting in no
loss of sound quality) and the surround signals
transmitted through the other speakers expand the
sound field naturally.
• THX Cinema can be applied together with Neo:6 Cinema when an
analog or digital 2-channel software is played back.
About Dual Mono
This format is now adopted in Dolby Digital, DTS, and so on.
When Dual Mono signals are detected, “DUAL MONO”
appears, and the DUAL indicator lights up on the display.
