Using the Surround Modes
This unit activates a variety of Surround modes automatically. The basic settings and adjustments stored (see pages
16 to 22) are applied automatically.
Reproducing Theater Ambience
In a movie theater, many speakers are located on the walls to
reproduce impressive multi-surround sounds, reaching you from all
directions.
With these many speakers, sound localization and sound movement
can be expressed.
Surround modes built in this receiver can create almost the same
surround sounds as you can feel in a real movie theater—with only
a limited number of the speakers.
Introducing the Surround Modes
Dolby Digital * 1
Dolby Digital is a digital signal compression method, developed
by Dolby Laboratories, and enables multi-channel encoding and
decoding (1ch up to 5.1ch).
• When Dolby Digital signal is detected through the digital input,
the indicator lights up on the display.
Dolby Digital 5.1CH
Dolby Digital 5.1CH (DOLBY DIGITAL) encoding method
records and digitally compresses the left front channel, right front
channel, center channel, left surround channel, right surround
channel, and LFE channel signals (total 6 channels, but the LFE
channel is counted as 0.1 channel. Therefore, called 5.1 channel).
Dolby Digital enables stereo surround sounds, and sets the cutoff
frequency of the surround treble at 20 kHz, compared to 7 kHz for
Dolby Pro Logic. As such, the sound movement and “being-there”
feeling are enhanced much more than Dolby Pro Logic.
Another digital surround encoding format introduced by Dolby
Laboratories is
Dolby Digital EX , which adds the third surround
channels, called “surround back.”
Compared to the conventional Dolby Digital 5.1CH, these newly
added surround back channels can reproduce more detailed
movements behind you while viewing the video software. In
addition, surround sound localization will become more stable.
• You can use Virtual Surround Back (see page 20) when playing
back Dolby Digital Surround EX software. This function creates
the great surround effect from the behind as if you have
connected the surround back speakers.
Dolby Pro Logic II
Dolby Pro Logic II is a multi-channel playback format to convert
2-channel software into 5-channel (plus subwoofer). The matrix-
based conversion method used for Dolby Pro Logic II makes no
limitation for the cutoff frequency of the surround treble and
enables stereo surround sound.
• This receiver provides three types of Dolby Pro Logic II
modes— Pro Logic II Movie (PLII MOVIE), Pro Logic II
Music (PLII MUSIC), and Pro Logic II Game (PLII GAME).
When Dolby Pro Logic II is activated, the PRO LOGIC
indicator lights up on the display.
PLII MOVIE: Suitable for playing any Dolby Surround
encoded software. You can enjoy a sound field
very close to the one created with discrete 5.1-
channel sounds.
PLII MUSIC: Suitable for playing any 2-channel stereo
software. You can enjoy wide and deep sounds.
PLII GAME: Suitable for playing a video game. You can
enjoy sounds with “being there” feeling.
