Pioneer VSX-452 - Manual (Page 5)

This unit has a built-in surround processor for adding presence and an
expansive effect to the sound.
• STUDIO:
Select this position to enjoy the effect of listening to music in a recording
studio.
The source sound is output as It is through the front speakers, with
reverberation output through the rear speakers.
This is particularly suitable for a source that has a lot of reverberation.
• SIMULATED SURROUND:
The "SIMULATED SURROUND" creates effects of reverberated and
reflected sound from the walls and ceiling similar to a concert hall. These
sound-effects added to the actual sound from the source make you feel
as If you were in a more expanded space. The different ranges of the
expaitded space can be set by the DELAY TIME button.
Set the Delay Time to 16 ms or 20 ms for a live-house concert. For
chamber music, set to 20 ms. For orchestral music, set to 30 ms. The
"SIMULATED SURROUND" also gives effects on monaural sources by
outputting the reverberated sound from rear speakers while keeping the
output sound from front speakers as it is. Turn on the "SIMULATED
SURROUND" for a monaural source to gain effective surround playback.
• DOLBY'*' PRO LOGIC SURROUND:
Choose this setting for movies and music (especially Video Discs and
video tapes bearing the
ПП
| DOLBY SUHHOUND | mark) playback.
DOLBY PRO LOGIC SURROUND continuously detects the size and
direction of the dominant signal and cancels undesirable crosstalk,
thereby providing signal emphasis.
It makes you clearly perceive the directions where music comes from.
Real flow of sound also can be re-created naturally using this feature.
You can feel as if being in the outstanding and expansive sound field.
When using DOLBY PRO LOGIC SURROUND, a delay time setting of
20 ms is commonly used. Use a different setting if you prefer.
Even if they do not bear the
ПП
| DOLBY SURROUND | mark, some
video recordings may be Dolby Surround encoded.
Choose the SIMULATED SURROUND mode if the source sound signal
is mono. Little or no sound will be heard from the surround speakers
if the STADIUM or DOLBY PRO LOGIC SURROUND mode is selected.
With DOLBY PRO LOGIC SURROUND, monaural source sound will be
heard only from the center channel at settings other than the PHANTOM
position.
Note:
Dolby Surround will not operate correctly if the signal passes through
a graphic equalizer.
When using Dolby Surround, set the graphic equalizer for flat
response or to its "through" (or off) setting, if you have one in use.
Cqmbining the rear speaker signal with that of the front speakers results
in your being able to enjoy a regenerated sound field which has
comparatively more presence and a more expansive feeling from the
front 3 channels (front L, front R, and center speakers) than that of
ordinary stereo regeneration.
[For DOLBY PRO LOGIC SURROUND and DOLBY 3CH
LOGIC]
You can choose from the following settings:
Center Mode Choices:
When using a center speaker:
• NORMAL — Low range frequencies, which have little effect on
directionality and positioning, are routed to the ieft and right front
speakers. So you can use a relatively small size speaker as the center
speaker.
• WIDE — If you use a large size center speaker, choose this setting.
The full frequency range of the Dolby Surround center channel, from
low to high, is routed to the center speaker.
When not using a center speaker: DOLBY PRO LOGIC SURROUND only
• PHANTOM — The signal which would have been sent to the center
speaker is divided equaliy between the left and right front speakers.
