SURROUND EFFECT

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 actual source sound is output through the front speakers,

and the added reverberated sound is output through the rear

speakers.

This is particularly suitable for a source that has a lot of

reverberation.

SIMULATED SURROUND:

The "SIMULATED

SURROUND"

creates the 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

amore 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 added reverberated

sound from the rear speakers while outputting the actual

source

sound

from

the front speakers.

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 D{)(boravsumouns|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 directional source

of the music. Real flow of sound also can be re-created

naturally using this feature. You can feel as if being in an

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

the video recordings do not bear the DU] [Bota sussouno}mark,

some of them may be Dolby Surround encoded. Choose the

SIMULATED SURROUND

mode if the source sound signa

is mono.

Little or no sound will be heard from the surround

speakers if the DOLBY PRO-LOGIC SURROUND mode is

selected. With DOLBY PRO-LOGIC SURROUND, monaura

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"

for off) setting, if you have one in use.

DOLBY 3CH LOGIC

Combining 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. DOLBY 3CH LOGIC can be used with stereo

sources not encoded with DOLBY SURROUND.
