Surround Effect And Dolby 3Ch Logic - Pioneer VSX-405 Operating Instructions Manual

VSX-295 model)
SURROUND EFFECT AND DOLBY 3CH LOGIC (Not available on the
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 rever-
berated 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 expanded space can be set by the DELAY TIME
button.
Set the Delay Time to 15 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 3CH LOGIC:
Combining the rear speaker signal with that of the front
speakers results in your being able to enjoy a regenerat-
ed 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 ordi-
nary stereo regeneration.

DOLBY* PRO LOGIC SURROUND:
Choose this setting for movies and music (especially
Video Discs and video tapes bearing the [{][potey surrouno]
mark) playback. DOLBY PRO LOGIC SURROUND contin-
uously detects the size and direction of the dominant
signal and cancels undesirable crosstalk, thereby provid-
ing 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 inthe
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 [j{][potey sumrouno] 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,
turn off the TAPE 2 MONITOR or set the graphic equalizer for
flat response or to its "through" (or off) setting, if you have
| one in use.

(For DOLBY PRO LOGIC SURROUND)
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 left and right front speakers. So you can use a
relatively small size speaker as the center speaker.
e 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.
e PHANTOM — The signal which would have been
sent to the center speaker is divided equally between
the left and right front speakers.
With DOLBY PRO LOGIC SURROUND, monaural source
sound will be heard only from the center channel at
settings other than the PHANTOM position.
