SURROUND EFFECT

This unit has a built-in surround processor for adding presence and an

expansive effect to the sound.

• STUDIO:

Select this positionto enjoythe effect of listeningto musicin erecording

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 e lot of reverberation.

• SIMULATED SURROUND:

The "SIMULATED SURROUND" creates effects of reverberated and

reflected soundfrom the wallsend ceilingsimilarto a concert hall.These

sound-effects added to the actual soundfrom 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 16 ms or 20 ms for a live-house concert. For

chamber music, set to 20 ms. Fororchestral music, set to 30 ms. The

"SIMULATED SURROUND" also gives effects on monaural sources by

outputting the reverberated sound from rear speakerswhile keeping the

output sound from front speakers as it is. Turn on the "SIMULATED

SURROUND" for a monauralsource to gaineffective surroundplayback.

• DOLBY* PRO LOGIC SURROUND:

Choose this setting for movies and music (especially Video Discs and

video tapes bearing the [_ IOOI.BYSURROUNDJ 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 cleady 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, e delay time setting of

20 ms is commonly used. Use a different setting if you prefer.

Even if they do not bear the I']D[ OOLIBY_ ] 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

heardonly from the center channelat settingsother than the PHANTOM

position.

Note:

Dolby Surround will notoperate correctly ifthe signalpassesthrough

a graphic equalizer.

When using Dolby Surround, set the graphic equalizer for flat

response orto its "through" (oroff) setting, if you have one inuse.

DOLBY 3CH LOGIC

Cqmbining the rearspeaker signalwith that of the front speakersresults

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.

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 smell 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 PROLOGICSURROUND only
