Using Surround Modes and DSP Modes
This unit activates a variety of Surround modes and DSP (Digital Signal Processor) modes. To use Surround and DSP
modes properly, speakers required for creating each Surround and DSP modes should be activated.
■ Surround Modes
Reproducing Theater Ambience
In a movie theater, many speakers are located on the walls to
reproduce impressive multi-surround sounds, reaching you from all
directions.
With these many speakers, sound localization and sound movement
can be expressed.
Surround modes built in this receiver can create almost the same
surround sounds as you can feel in a real movie theater.
Introducing the Surround Modes
■ Dolby Surround
Dolby Digital EX*
Dolby Digital EX is newly introduced surround encoding format as
an extension of multi-channel Dolby Digital, designed to add an
extra surround channel to Dolby Digital 5.1-channel (see below). By
using a matrix encoding/decoding method, additional “surround
back” channel signal is encoded (and decoded) in both the left and
right surround channel signals.
Compared to the conventional Dolby Digital 5.1-channel, this 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, so
that you can enjoy a realistic surround field in your listening room.
Best used to reproduce multi-channel movie sound tracks of the
software encoded with Dolby Digital EX (
).
• To enjoy the software encoded with Dolby Digital EX, connect the
source component using the digital terminals on the rear of this
receiver. (See page 13.)
Dolby Digital*
Used to reproduce multi-channel sound tracks of the software
encoded with Dolby Digital (
DIGITAL
).
Dolby Digital 5.1-channel encoding method (so-called discrete
5.1-channel digital audio format) 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 LFE channel is counted as 0.1 channel,
therefore, called 5.1-channel).
Since each channel is completely independent from the other
channel signals to avoid interference, you can obtain a much better
sound quality with better stereo and surround effects.
• To enjoy the software encoded with Dolby Digital, connect the
source component using the digital terminals on the rear of this
receiver. (See page 13.)
* Dolby Digital software can be roughly grouped into two categories
—multi-channel (up to 5.1-channel) and 2-channel software. To
enjoy surround sounds while playing Dolby Digital 2-channel
software, you can use Dolby Pro Logic II.
Dolby Pro Logic II*
Dolby Pro Logic II has a newly developed multi-channel playback
format to convert all 2-channel software into 5-channel (plus Subwoofer).
Matrix-based conversion method for Dolby Pro Logic II makes no
limitation for the cutoff frequency of the surround treble and enables
stereo surround sound unavailable with conventional Dolby Pro Logic.
Dolby Pro Logic II can reproduce spacious sound from original
sound without adding any new sounds and tonal colorations.
Dolby Pro Logic II has two modes—Movie mode and Music mode:
Pro Logic II Movie (PL II MOVIE)—suitable for the reproduction
of Dolby Surround encoded sources bearing the mark
DOLBY SURROUND
.
You can enjoy a sound field very close to the one created with
discrete 5.1-channel sounds.
Pro Logic II Music (PL II MUSIC)—suitable for the reproduction
of any 2-channel stereo sources. You can enjoy wide and deep sound
by using this mode. For this mode, you can make precise
adjustments to match the sound to your taste.
• When Dolby Pro Logic II is activated, the
PRO LOGIC II
indicator lights up on the display.
