Overview  
The SA-VA15 is an active home-theater speaker system  
incorporating a Dolby Pro Logic decoder and super  
woofer speakers. Its design features include easy  
connection to your current TV/VCR setup. You can  
connect this speaker system without having to  
reconnect the cords of your TV and VCR. Also, you  
don't have to connect a center speaker to optimize the  
surround effects. Easy operation via the supplied  
remote ensures maximum enjoyment of the home-  
theater sound this system provides.  
Three different types of surround sound  
accommodate a variety of program sources  
Dolby Surround (Pro Logic) mode  
Lets you enjoy superb theater-like presence and  
surround effects in your home when playing back  
video software encoded with the Dolby Surround  
system.  
HALL surround mode  
Provides a sense of presence similar to that of an open-  
air stadium. Ideal for maximum enjoyment of  
broadcasts of sporting events like football.  
SIMULATED surround mode  
Creates simulated stereo surround effects from  
monaural sound sources, like old movies or monaural  
TV shows.

Overview  
Built-in center speakers let you enjoy Dolby  
Pro Logic Surround sound  
Dynamic Bass Roar (DBR) super woofer  
system provides theater-like bass sound  
The use of a center speaker is a key factor in obtaining  
a full surround effect when playing sources encoded  
with the Dolby Pro Logic Surround sound system.  
Center speakers in a movie theater make central  
sounds, such as dialogue, clearer and create a unified  
sound image.  
To provide a theater-like experience complete with  
dynamic bass sounds, this speaker system incorporates  
the Super Acoustically-loaded Woofer (SAW) design  
(see below) in the left and right front speakers to form  
a DBR super woofer system.  
Normally, you have to install a center speaker  
separately, but this speaker system makes it easy to set  
up a high-performance home theater system by  
incorporating a high-quality center speaker system into  
the front speakers.

Drive unit  
Main duct  
In addition, rear speakers are also provided with this  
system to create a complete home-theater that lets you  
enjoy the maximum surround effect.  
Top view  
What is the SAW design?  
The SAW design features a centrally-positioned woofer  
drive unit, two chamber construction, and a long main duct.  
Through precision control of the acoustics of the two  
chambers, the unit can reproduce powerful ultra low  
frequencies without muddiness.  
Center channel  
tweeters  
In addition, we also included two super woofer modes  
designed to bring the dynamic bass sounds found in  
movie theaters (mode 1) and concert halls (mode 2) to  
your living room.

Power turns on and off automatically  
The speakers turn on automatically when a sound  
signal is input and turn off when you've finished  
watching a program and the sound signal goes out. So  
you don't have to bother using the power switch every  
time you use the system.  
Super woofers  
Rear speakers  
How the center speaker works  
The front left and right speakers are equipped with center  
channel tweeters (see above) angled inwards at 30° to  
reproduce high-frequency center channel sounds. Low-  
frequency center channel sounds are mixed with the front  
channel signals and reproduced through the front left and  
right full range units. This design produces a high-quality  
centralized sound image for the center channel which  
exactly matches the quality of the front channel sound to  
provide superior sound quality and a unified sound image  
without a cumbersome external center speaker.

Getting Started  
Precautions  
Unpacking  
Check that you received the following items with your  
speaker system:  
• Front L/R speaker connecting cord, 3.5 m (1)  
• Rear speakers SS–SR151 (2)  
On safety  
• Should any solid object or liquid fall into the cabinet,  
unplug the speaker system and have it checked by  
qualified personnel before operating it any further.  
• Rear speaker connecting cords, 10 m (2)  
• Audio connecting cord, 1.5 m (1)  
• Remote commander (remote) RM–J15 (1)  
• Size AA (R6) batteries (2)  
• Speaker Stands (2)  
• Screws (8)  
On power sources  
• Before operating the speakers, check that the operating  
voltage is identical with your local power supply. The  
operating voltage is indicated on the nameplate on the  
rear of the speakers.  
• The speakers are not disconnected from the AC power  
source as long as they are connected to the wall outlet,  
even if the speakers themselves have been turned off.  
• If you are not going to use the speakers for a long time, be  
sure to disconnect the speakers from the wall outlet. To  
disconnect the AC power cord, grasp the plug itself;  
never pull the cord.  
• One blade of the plug is wider than the other for the  
purpose of safety and will fit into the wall outlet only one  
way. If you are unable to insert the plug fully into the  
outlet, contact your dealer.  
Inserting batteries into the remote  
Insert two size AA (R6) batteries with the + and – on  
the battery compartment. When using the remote,  
point it at the remote sensor g on the left front  
speaker.  
• Should the AC power cord need to be changed, have it  
done at a qualified service shop only.  
]
}
}
On placement  
]
• Do not place the speakers near heat sources, or in a place  
subject to direct sunlight, excessive dust or mechanical  
shock.  
• Good ventilation is essential to prevent internal heat  
buildup. Place the speakers in a location with adequate air  
circulation, and in a way that does not block the rear  
ventilation holes.  
When to replace batteries  
Under normal use, the batteries should last for about 6  
months. When the remote no longer operates the  
speakers, replace both batteries with new ones.  
On cleaning  
• Clean the cabinet, panel and controls with a soft cloth  
slightly moistened with a mild detergent solution. Do not  
use any type of abrasive pad, scouring powder or solvent  
such as alcohol or benzine.  
Notes  
• Do not leave the remote in an extremely hot or humid  
place.  
• Do not use a new battery with an old one.  
• Do not expose the remote sensor to direct sunlight or  
lighting apparatuses. Doing so may cause a malfunction.  
• If you don’t use the remote for an extended period of time,  
remove the batteries to avoid possible damage from  
battery leakage and corrosion.  
For the customers in the USA  
For detailed safety precautions, see the “IMPORTANT  
SAFEGUARDS” leaflet.  
If you have any question or problem concerning your  
receiver, please consult your nearest Sony dealer.

Getting Started  
Installing the Speaker Stands  
Choosing the Best Location  
Be sure to install the supplied speaker stands before  
you use the speakers.  
To obtain high sound quality and a proper sound  
image from the front speakers, place the speaker with  
the built–in operation panel to the left of your TV and  
the other to the right of your TV so that the center  
channel tweeters angle towards the center of the room.  
1
Spread a towel, or other soft cloth, over a table  
and lay the speakers down.  
For the best central sound image, place the left and  
right speakers within 8 feet of each other and  
equidistant from the TV.  
8 feet (max)

Select WIDE mode if you connect an active  
center speaker equivalent to the two front  
speakers. With the WIDE mode, you can  
take full advantage of Dolby Surround  
sound.  
Decoding system of Dolby Surround sound  
standardized in TV programs and movies.  
Compared with the former Dolby Surround  
system, Dolby Pro Logic Surround improves  
sound image by using four separate channels:  
off-screen audio effects, on-screen dialog,  
left-to-right panning, and music. These  
channels manipulate the sound to be heard  
and enhance the action as it happens on the  
screen. To take advantage of Dolby Pro Logic,  
you should have at least one pair of rear  
speakers and/or one center speaker. You also  
need to select the appropriate center mode to  
enjoy a full effect.
