SURROUND EFFECT AND DOLBY 3CH LOGIC

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 Jot 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" aiso

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 Dises and video tapes bearing the DO [bormy sune

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 in the

outstanding

and expansive sound

field, When

tsing

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 D][oisy

i] mark,

some video recordings may be Dolby Surround

encod-

ed. 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

DOLBY PRO LOGIC SURROUND mode is selected.

With DOLBY PRO LOGIC SURROUND,

monaural source

sound will be heard

only from the center channel

settings other than the PHANTOM

position.

Note:

Doiby 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.

_DOLBY PRO LOGIC SURROUND, CENTER MODE

(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 smail 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 Doiby

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.
