Enjoying

Surround

You can take advantage of surround sound simply by

selecting one of the pre-programmed "sound fields" that

your receiver provides. You can enjoy the sound of a

movie theater or concert hall in your own home. You can

even customize a sound field by adjusting its parameters.

Sound fields are classified into two genres.

One gerue is "CINEMA." The CINEMA-genre sound

-'-^-«i«,-j#5t»^lki*.^-*J5^-V';:
fields are designed for enjoying movies recorded on

videos or laser discs. Sue sound fields are included in the
CINEMA gerue and they are grouped into two types.
PRO LOGIC sound field can be used to reproduce plriin
surround sound. When you select the PRO LOGIC sound

field, the receiver decodes the software that is encoded
using the Dolby Pro Logic system to obtain surround
sound. The surround sound is reproduced in the exact
way that the sound engineer of the software intended.
Other sound fields in the CINEMA gerue are designed to
add more reverberation effects by incorporating Digital
Cinema Sound technology. When you select these sound
fields, the receiver adds the reflection and reverberation
effects that are typical in movie theaters to the decoded
Dolby Pro Logic Surround sound. You can enjoy the
sound that you would experience in the movie theater.

Another gerue is "MUSIC." When a sound field in this

genre is selected, the receiver adds the reverberation to

the normal 2-charmel stereo sound. You can apply these
sound fields when playing a CD or watching TV
programs to obtain the surround effects of concert hall or
a stadium.

To enjoy Dolby Pro Logic Surround sound fully, do the
procedure on "Dolby Surround Setup" starting from page
15 to select the center mode and adjust the speaker
volume.

See the table on page 26 for information on each sound
field.

V The receiver memorizes the last sound field selected for each
program source (Sound Field Link)

Whenever you select a program source, the sound field that was
last applied is automatically applied again. For example, if you
listen to CD with STADIUM as the sound field, change to
difierent program source, then return to CD, STADIUM will be
applied again. In the case of the tuner, the sound fields for AM or
FM band and for all the preset stations are memorized separately.

V You can identify Dolby Surround-^tooded software by
looking at the packaging . ^

Some videos and laser discs, however, may be encoded with
Dolby Surround sound even if it's not indicated on the package.

Notes

• when using sound fields, do not select both speakers (A+B)
with the SPEAKERS selector.

• Sound fields are turned off whenever the program source
connected to the 5.1 INPUT jacks is selected.

names (for example, "VHS") appeeur in the receiver's
dispbjr when a station or program source is selected.
Note that no more than one name can be entered for each
preset station or program source.

This function is useful for distinguishing components of

the same kind. For example, two VCRs can be specified

as 'VHS" and "8MM," respectively. It is also h<mdy for
ident^ring components connected to jacks meant for
another type of component, for example, a second CD
player connected to the TAPE/MD jacks.

Glossary

Surround sound

Sound that consists of tlvee elements;
direct sound, early reflected sound
(early reflections) and reverberative
sound (reverberation). The acoustics

of the surrounding space affect the
way these three sound elements are
heard. Surround sound combines
these sound elements in Such a way
that you actually can sense the size of
the venue, as well as its type.

• Types of sound

Earty reflections

Reverberation

• Transition of sound from rear speakers

Direct sound

Dolby Pro Logic Surround

As one method of decoding Dolby
Surround, Dolby Pro Logic Surround
produces four channels from two­charmel sound. Compared with the
former Dolby Surround system,
Dolby Pro Logic Surround reproduces
left-to-right panning more naturally
and localizes sounds more precisely.

To take full advrmtage of Dolby Pro

Logic Surround, you should have one

pair of rear speakers and a center
speaker. The rear speakers output
monaural sound.

Dolby Digital (AC-3)

This sound format for movie theaters
is more advrmced than Dolby Pro
Logic Surround. In this format, the
tear speakers output stereo sound
with an expanded frequency range

and a subwoofer channel for deep
bass is independently provided. This
format is also called "5.1" because the
subwoofer channel is counted as 0.1
charutel (since it functions only when
a deep bass effect is needed). All six
channels in this format are recorded
separately to rerdize superior charutel
separation. Furthermore, since ail the

sigitals are processed digitally, less
signal degradation occurs. The name
"AC-3" comes from the fact that it is
the third audio coding method to be
developed by the Dolby Laboratories
Licensing Corporation.

Digital Cinema Sound

This is the generic name of the
surround sound produced by digital
signal processing technology
developed by Sony. Lfnlike previous

surround sound fields mainly
directed at the reproduction of music.
Digital Cinema Sound is designed
specifically for the enjoyment of
movies.

5.1/DVD INPUT jacks

These jacks are used to input decoded

Dolby Digital (AC-3) audio signals,

allowing you to enjoy 5.1 charmel
surround sound. Use these jacks to
connect a Dolby Digital (AC-3)
decoder or a DVD player with a built­in AC-3 decoder.
