Creating realistic sound fields
Reproducing theater ambience
In a movie theater, many speakers are located on the walls to
reproduce impressive multi-surround sound, reaching you from all
directions.
With these many speakers, sound localization and sound movement
can be expressed.
Surround/DSP modes built in this receiver can create almost the
same surround sound as you can feel in a real movie theater.
Introducing the Surround/DSP modes
You can use the following Surround/DSP modes with this receiver.
■ Surround modes
• Dolby Pro Logic II
• Dolby Digital
• DTS
■ DSP (Digital Signal Processor) modes
• DAP (Digital Acoustic Processor) modes
• All Channel Stereo
■ Surround modes
Dolby Pro Logic II*
Dolby Pro Logic II has a newly developed multi-channel 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 surround treble and
enables stereo surround sound compared to conventional Dolby Pro
Logic.
Dolby Pro Logic II enables you 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 a
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 PLII indicator lights up
on the display.
Dolby Digital*
Dolby Digital is a digital signal compression method, developed by
Dolby Laboratories, and enables multi-channel encoding and
decoding (1 channel up to 5.1 channel).
Dolby Digital 5.1 channel 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, it is 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.
• To enjoy software encoded with Dolby Digital, connect the source
component using the digital terminal on the rear of this receiver.
(See page 7.)
NOTE
Dolby Digital software can be roughly grouped into two categories
—multi-channel (up to 5.1 channel) and 2 channel software. To enjoy
surround sound while playing Dolby Digital 2 channel software, you
can use Dolby Pro Logic II.
