Dolby Pro Logic II*
Dolby Pro Logic II has newly developed multichannel
playback format to decode all 2 channel sources—stereo
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
DOLBY SURROUND
. You can enjoy soundfield 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 window.

You can use the following Surround modes to reproduce a realistic sound field.
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.
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.
7 DTS Digital Surround**
Used to reproduce multichannel soundtracks of the software
encoded with DTS Digital Surround (
).
DTS Digital Surround (DTS SURR) 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.
