Dolby Digital*
Used to reproduce multichannel sound tracks of the software
encoded with Dolby Digital (
D I G I T A L
).
• To enjoy the software encoded with Dolby Digital, connect the
source component using the digital terminal on the rear of this
receiver. (See page 7.)
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 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 software, you
can use Dolby Pro Logic II.

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—suitable for reproduction of Dolby Surround
encoded sources bearing the mark
DOLBY SURROUND . You can enjoy
sound field very close to the one created with discrete 5.1-channel
sounds.
Pro Logic II Music—suitable for 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 PL II indicator
lights up on the display.

■ 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 receiver. (See page 7.)
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.
