noise.  
• When connecting an audio/ video cord, be sure to  
match the color-coded pins to the appropriate jacks on  
the components: yellow (video) to yellow; white (left,  
audio) to white; and red (right, audio) to red.

5.1 In p u t Ho o ku p s  
This receiver is equipped with 5.1/ DVD INPUT jacks. By  
connecting your DVD player or other digital video source  
through a multi-channel decoder (e.g., Dolby Digital (AC-  
3) decoder) to these jacks, you can enjoy theater-quality  
Multi-Channel Surround sound in your own home. To  
enjoy Multi-Channel Surround sound to its full extent,  
you will need five speakers (two front speakers, two rear  
speakers, and a center speaker) and a subwoofer. Refer to  
the instruction manual supplied with your Dolby Digital  
(AC-3) decoder etc., for details on the 5.1-channel input  
hookups.

If you have a CONTROL S-compatible Sony TV, DBS  
tuner, monitor, or VCR, use an audio/ video/ control S  
connecting cord (supplied) or a control S connecting cord  
(supplied) to connect the CTRL S (STATUS) IN (for TV,  
DBS tuner, or monitor) or OUT (for VCR etc.) jack on the  
receiver to the appropriate S-LINK jack on the respective  
component. Refer to the operating instructions supplied  
with your TV, DBS tuner, monitor, VCR, etc., for details.  
• If yo u h a ve a CONTROL A1-co m p a t ib le So n y CD

Use a CONTROL A1 cord (not supplied) to connect the  
S-LINK CTRL A1 jack on the CD player, tape deck, or  
MD deck to the S-LINK CTRL A1 jack on the receiver.  
See “Displaying the operating status of the component  
connected to the S-LINK CTRL A1 jack” on page 36 and  
refer to the separate manual “CONTROL-A1 Control  
System” and the operating instructions supplied with  
your CD player, tape deck, or MD deck for details.  
An example of a CONTROL S hookup between the  
receiver and TV or VCR is shown below.  
When your TV is connected to the receiver as shown  
below, the TV input mode will change to video input  
whenever you turn on the receiver.  
When you connect the VCR to the receiver as shown  
below, the input mode of the receiver changes to video 1  
(or 2) whenever you turn on the VCR.

If your CD changer’s COMMAND MODE selector can  
be set to CD 1, CD 2, or CD 3, be sure to set the  
command mode to “CD 1” and connect the changer to  
the CD jacks on the receiver.

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.  
Enjoying  
Surround  
Sound  
Sound fields are classified into two genres.  
One genre is “CINEMA.” The CINEMA-genre sound  
fields are designed for enjoying movies recorded on  
videos or laser discs. Six sound fields are included in the  
CINEMA genre and they are grouped into two types.  
PRO LOGIC sound field can be used to reproduce plain  
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 genre 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.  
This chapter describes how to set up  
the receiver to enjoy surround sound.  
You can enjoy the Dolby Surround-  
encoded software using this receiver.  
Another genre is “MUSIC.” When a sound field in this  
genre is selected, the receiver adds the reverberation to  
the normal 2-channel 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.

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 spplied again. For example, if you  
listen to CD with STADIUM as the sound field, change to  
different 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.  
TONE ON/OFF button: Turns the tone effect on or off.  
z
You can identify Dolby Surround-encoded 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.

the playback and recording components directly to each  
other: once you select a program source on the receiver,  
you can record and edit as you normally would using the  
controls on each component.  
You can enter a name of up to 8 characters for preset  
stations (station index) and program sources. These index  
names (for example, “VHS”) appear in the receiver’s  
display 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 handy for  
identifying components connected to jacks meant for  
another type of component, for example, a second CD  
player connected to the TAPE/ MD jacks.  
Before you begin, make sure you’ve connected all  
components properly.

Do lb y Dig it a l (AC-3)  
Sound that consists of three 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.  
This sound format for movie theaters  
is more advanced than Dolby Pro  
Logic Surround. In this format, the  
rear 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  
channel (since it functions only when  
a deep bass effect is needed). All six  
channels in this format are recorded  
separately to realize superior channel  
separation. Furthermore, since all the  
signals 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.

Direct sound  
This is the generic name of the

developed by Sony. Unlike previous

specifically for the enjoyment of  
movies.

These jacks are used to input decoded

allowing you to enjoy 5.1 channel  
surround sound. Use these jacks to  
connect a Dolby Digital (AC-3)  
decoder or a DVD player with a built-  
in AC-3 decoder.  
As one method of decoding Dolby  
Surround, Dolby Pro Logic Surround  
produces four channels from two-  
channel 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 advantage of Dolby Pro  
Logic Surround, you should have one  
pair of rear speakers and a center  
speaker. The rear speakers output  
monaural sound.
