Dolby Digital
5.1 channel encoding method (so-called
discrete multi-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.
Since each channel is completely independent from the other
channel signals to avoid interference, you can obtain much
better sound quality with many stereo and surround effects.
• When Dolby Digital signal comes in, the
DIGITAL
indicator lights up on the display.
Note:
Dolby Digital software can roughly be 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.

DTS Digital Surround
**
Used to reproduce multi-channel sound tracks of software
encoded with DTS Digital Surround (
).
• To use software encoded with DTS Digital Surround, connect
the source component to the digital terminal on the rear of
this receiver. (See page 10.)
DTS Digital Surround
is another discrete multi-channel
digital audio format available on CD, LD, and DVD software.
Compared to Dolby Digital, the 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.
• When DTS signal comes in, the
indicator lights up on
the display.

Dolby Pro Logic II
*
Dolby Pro Logic II
has a multi-channel playback format to
decode all 2 channel sources—stereo source and Dolby
Surround encoded source—into 5.1 channels.
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 reproduction of 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 music sources. You can
enjoy wide and deep sound by using this mode. For this mode,
Panorama control can be selected, which gives “wraparound”
sound effect with side-wall image.
• When Dolby Pro Logic II is activated, the
PRO LOGIC II
indicator lights up on the display.
