Creating realistic
sound fields
Reproducing theater ambience
In a movie theater, many speakers are located on the walls to
reproduce impressive multi-channel sound, reaching you from
all directions.
With these many speakers, sound localization and sound
movement can be expressed.
Surround/DSP modes built in this receiver can create almost
the same Surround sound as you can feel in a real movie
theater.
Introducing the Surround modes
7 Dolby Digital*
Dolby Digital is a digital signal compression method,
developed by Dolby Laboratories, and enables multi-channel
encoding and decoding.
• When Dolby Digital signal is detected through the digital
input, the indicator lights up on the display.
Dolby Digital 5.1CH
Dolby Digital 5.1CH (DOLBY DIGITAL) encoding method
records and digitally compresses the left front channel, right
front channel, center channel, left surround channel, right
surround channel, and LFE channel signals (total 6 channels,
but the LFE channel is counted as 0.1 channel; therefore,
called 5.1 channel).
Dolby Digital enables stereo surround sounds, and sets the
cutoff frequency of the surround treble at 20 kHz, compared
to 7 kHz for Dolby Pro Logic. As such, the sound movement
and “being-there” feeling are enhanced much more than
Dolby Pro Logic.
Dolby Digital EX
Dolby Digital EX (DOLBY D EX) is a digital surround encoding
format that adds the third surround channels, called “surround
back.”
Compared to the conventional Dolby Digital 5.1CH, these
newly added surround back channels can reproduce more
detailed movements behind you while viewing the video
software. In addition, surround sound localization will become
more stable.
7 Dolby Surround
Dolby Pro Logic II
Dolby Pro Logic II is a multi-channel playback decoder 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 three types of Dolby Pro Logic II
modes—Pro Logic II Movie (PLII MOVIE), Pro Logic II Music
(PLII MUSIC), and Pro Logic II Game (PLII GAME).
When Dolby Pro Logic II is activated, the
indicator
lights up on the display.
PLII 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.
PLII MUSIC Suitable for playing any 2-channel stereo
software. You can enjoy wide and deep
sounds.
PLII GAME Suitable for when playing a video game. You
can enjoy sounds with “being there” feeling.
