SURROUND EFFECTS

When you use the surround function, the sound creates
a "live" atmosphere such as that experienced in movie
theaters, disco, stadium and concert halls.

Available Surround Modes

This unit is provided with the following surround
modes, which can be selected using the SURROUND
MODE switches.
Select the appropriate SURROUND MODE according to
the program source.
Note that surround speakers are needed for the
DOLBY PRO LOGIC Surround mode to function, and
a center speaker is needed for the DOLBY 3 STEREO
mode to function.
DOLBY DIGITAL Surround
The Dolby Digital surround format lets you enjoy up to
5.1 channels of digital surround sound from a Dolby
Digital program source. If you connect a DVD player or
an LD player equipped with an AC-3 DIGITAL output to
the AC-3 DIGITAL IN jack on a surround receiver/ampli-
fier or surround processor and play DVD or laser discs
with ( ) or (
better sound quality, greater spatial accuracy, and
improved dynamic range. This is because Dolby Digital
delivers up to 5 totally discrete, full frequency audio
channels (front left and right, center, and surround left
and right), plus 0.1 channel called LFE* ( bass-only
effects channel).
Dolby Digital AC-3 (Audio Coding 3) is a system devel-
oped by Dolby Laboratories that transmits 5.1 channels
of digital signals. The surround system developed for
movie theaters using this system is called "Dolby SR-D
(Surround Digital)". Because each channel is complete-
ly independent, a realistic sound field with a "three-
dimensional" feel is achieved which gives the sound a
sense of distance, movement and relative position, cre-
ating a surprisingly real and powerful sense of pres-
ence.
Some Dolby Digital programs carry information that
allow you to compress the dynamic range of sound
track, without degrading the sound quality, for softer
sound effects when you listen late at night.
* LFE = Low Frequency Extension
This channel delivers separate non-directional
bass signals to the subwoofer for more dynam-
ic deep bass sound effects.
DOLBY PRO LOGIC Surround
Use this mode when playing movie or music video soft-
ware which carries the Î DOLBY SURROUND mark.
This mode provides the effect of being in a movie
theater or live concert house-an effect with an intensity
which can only be obtained through DOLBY PRO LOGIC
SURROUND.
) mark, you can enjoy even
The main feature of DOLBY PRO LOGIC SURROUND is
that the separation between the various channels is
significantly improved from the 3 dB of previous
systems to 26-40 dB. As a result, the effect of the
front/back/left/right movement of the sound image, as
well as the sense of fixed position in the sound image,
is much clearer and more dynamic than before.
In addition, movie dialogue and other sounds which
should naturally be heard from the center are output
through an independent center channel, providing a
high degree of focus for dialogue.
DOLBY 3 STEREO
Front speakers receive rear (surround) speaker signals
in addition to front speakers signals. Center speaker
works similarly as that of DOLBY PRO LOGIC mode. In
this way, you can enjoy playback sound having superior
sound positioning.
HALL Surround
When playing recordings of live music, this mode pro-
vides a feeling similar to actually being in a concert
hall. When this mode is selected, the normal program
source is directed to the main speakers and a reverber-
ated sound is directed to the surround speakers.
This mode is suited to program sources which contain a
large amount of reverberation.
THEATER Surround
This mode provides a three dimensional effect similar
to that of movie theater. With this mode, you can enjoy
a surround effect similar to Dolby Surround sound even
when playing a video program which is not encoded
with the Dolby Surround system.
DISCO Surround
Gives a greatly expanded feel to powerful music such
as dance or rock.
STADIUM Surround
The reverberation of this mode produces a sound field
which recreates the sound of a stadium.
STEREO
Sound is produced from the two front channels.
Nothing is output from the surround and center chan-
nels.
