Creating Realistic Sound Fields

You can use the following surround to reproduce a realistic sound
field.

• Dolby Surround

• Dolby Pro Logic II

• Dolby Digital

• DTS Digital Surround

• DSP modes
7 Dolby Surround
Dolby Pro Logic II*
Dolby Pro Logic II has newly developed multichannel playback
format to decode the 2 channel sources—stereo analog source,
Linear PCM digital source, and Dolby Surround encoded source—
into 5.1 channel.
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.
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
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
indicator lights up on the display window.
7 Dolby Digital*
Used to reproduce multichannel soundtracks of the software
encoded with Dolby Digital (
Dolby Digital 5.1 ch (DOLBY D) 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.
When the system detects Dolby Digital signals, the
indicator lights up on the display.
Note:
Dolby Digital 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 ch software, you can
use Dolby Pro Logic II.

I DTS Digital Surround**
Used to reproduce multichannel sound tracks of the software
encoded with DTS Digital Surround (
DTS Digital Surround is another discrete 5.1 channel digital audio
format available on CD, LD, and DVD software.
Compared to Dolby Digital, audio compression rate 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.
When the system detects DTS Digital Surround signals, the
indicator lights up on the display.
