Using the Surround Modes
This unit activates a variety of Surround modes automatically. The basic settings and adjustments stored (see pages
23 to 31) are applied.
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
five to seven speakers (plus subwoofer).
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 DIGITAL indicator lights up on the display.
Dolby Digital 5.1CH
Dolby Digital 5.1CH (DOLBY D) 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.
Dolby Digital EX
Dolby Digital EX (DOLBY D EX) is a digital surround encoding
format that 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 6.1-channel surround when playing back
Dolby Digital EX software without connecting the surround
back speakers. This surround reallocates the surround back
channel to the surround speakers so that you can still feel the
great surround effect from behind.
The VIRTUAL SB (Surround Back) indicator lights up on the
display.
Dolby Pro Logic
Dolby Surround encoding format records the left front channel,
right front channel, center channel, and surround channel
(monaural) signals into 2 channels.
The Dolby Pro Logic (PRO LOGIC) decoder built in this receiver
decodes these 2 channel signals into 4 original channel signals
(plus subwoofer)—matrix-based multi-channel reproduction.
• When Dolby Pro Logic is activated, the
indicator
lights up on the display.
