Creating Realistic Sound Fields
You can use the following Surround modes to reproduce a realistic
sound field:
■ Dolby Surround
• Dolby Pro Logic II
• Dolby Digital
■ DTS Digital Surround
■ DAP (Digital Acoustic Processor) modes
■ All Channel Stereo
For DVD AUDIO multichannel surround, see page 43.
■ Dolby Surround
Dolby Pro Logic II*
Dolby Pro Logic II has newly developed multichannel playback
format to decode into 5.1-channel from all 2-channel sources—
stereo source and Dolby Digital encoded source.
Matrix-based encoding/decoding method for Dolby Pro Logic II
makes no limitation for the cutoff frequency of the rear treble and
enables stereo rear sound compared to conventional Dolby Pro
Logic.
• You cannot select Dolby Pro Logic II when playing back DVD
AUDIO.
Dolby Pro Logic II enables to 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 reproduction of
Dolby Surround encoded sources bearing the mark
DOLBY SURROUND
and stereo television sources. You can enjoy sound field very close
to the one created with discrete 5.1-channel sounds.
Pro Logic II Music (PL II MUSIC)—suitable for reproduction of
any 2-channel stereo music sources. You can enjoy wide and deep
sound by using this mode.
• When Dolby Pro Logic II is activated, the
PRO LOGIC II
indicator lights up on the display.
Dolby Digital*
Used to reproduce multichannel sound tracks of the software
encoded with Dolby Digital (
DIGITAL
).
• To enjoy the software encoded with Dolby Digital, connect the
source component using the digital terminal on the rear of this
unit. (See page 10.)
Dolby Digital 5.1-channel encoding method (so-called discrete
multichannel digital audio format) records and digitally compresses
the left front channel, right front channel, center channel, left rear
channel, right rear channel, and LFE channel signals.
Since each channel is completely independent from the other
channel signals to avoid interference, you can obtain much better
sound quality with much stereo and surround effects.
Note:
• Dolby Digital or DTS software can be roughly grouped into two
categories—multichannel (up to 5.1-channel) and 2-channel
software. To enjoy surround sounds while playing Dolby Digital 2-
channel or DTS software, you can use Dolby Pro Logic II.
■ DTS Digital Surround**
Used to reproduce multichannel sound tracks of the software
encoded with DTS Digital Surround (
).
• To enjoy the software encoded with DTS Digital Surround,
connect the source component using the digital terminal on the
rear of this unit. (See page 10.)
DTS Digital Surround is another discrete multichannel digital
audio format available on CD, LD, and DVD software.
Compared to Dolby Digital, audio compression ratio is relatively
low. This fact allows DTS Digital Surround format to add breadth
and depth to the reproduced sounds. As a result, DTS Digital
Surround features natural, solid and clear sound.
■ DAP (Digital Acoustic Processor) modes
DAP modes have been designed to create important acoustic
surround elements.
• You cannot select DAP modes when playing back DVD
AUDIO.
The sound heard in a live club, dance club, hall or pavilion consists
of direct sound and indirect sound—early reflections and reflections
from behind. Direct sounds reach the listener directly without any
reflection. On the other hand, indirect sounds are delayed by the
distances of the ceiling and walls (see the diagram below).
These indirect sounds are important elements of the acoustic
surround effects. The DAP mode can reproduce a realistic sound
field by adding these indirect sounds.
DAP modes can be used when the front and rear speakers are
connected to this unit (without respect to the center speaker
connection: no sound comes out of the center speaker even if it is
connected).
