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 home­theater 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 open­air 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

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.
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.

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

tweeters

Dynamic Bass Roar (DBR) super woofer system provides theater-like bass sound

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.

What is the SAW design?

The SAW design features a centrally-positioned woofer drive
uiut, 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.

Front view

Center channel

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. Low­frequency center channel sounds are mixed with the front

chaimel 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.

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.

Getting Started

Precautions

On safety

• Should any solid object or liquid fall into the cabinet, unplug
the speaker system and have it checked by qualified

persomiel before operating it any further.

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 discoimect the speakers from the wall outlet. To
discormect 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.

• Should the AC power cord need to be changed, have it done
at a qutilified service shop ordy.

Unpacking

Check that you received the following items with your
speaker system:

• Front L/R speaker connecting cord, 3.5 m

• Rear speakers SS-SR151 (2)

• 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)

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 B on the left front
speaker.

(1)

On placement

• Do not place the speakers near heat sources, or in a place
subject to direct sunligfit, 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.

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.

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.

'Q' 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.

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.

Getting Started

Installing the Speaker Stands

Be sure to install the supplied speaker stands'before
you use the speakers.

1 Spread a towel, or other soft cloth, over a table and

lay the speakers down.

2 Align the pins on the stands with the holes on the

bottom of the speakers.

Choosing the Best Location

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.

For the best central sound image, place the left and
right speakers within 8 feet of each other and
equidistant from the TV.

of the speakers with the supplied wood screws (4
for each speaker).

4 Make sure the stands are securely attached and

stand the speaker upright.

Place the rear speakers so that they fire directly across
at each other about 2 to 3 feet above your listening
position.

Getting Started

STEPS

Connecting your TV

If the audio and video output jacks on your TV and

VCR are already connected, and your TV has stereo

AUDIO OUT jacks, you can start enjoying surround
sound simply by connecting the speaker system to
your TV as shown below.

Important

• Set the volume on your TV to MIN (minimum).

• If your TV has an ON / OFF switch for its internal speaker,
set it to OFF and enjoy the sound from this speaker system.

TV front left speaker

If you use AUDIO OUT jacks marked VARIABLE

After making the connection as shown above, turn up the
volume on the TV. Use this speaker system's volume control
for regular volume adjustment. Turning down the volume on
the TV reduces the AUDIO OUT signal level and may cause a
loss in sound quahty and/or the auto-power off function (see
page 10) to activate.

If you have an additional VCR or LO player

Coimect it to the 2 IN jacks and connect the 2 OUT jacks to
the AUDIO IN jack on the back of your TV.

STEP 4

Connecting the AC power cord

Audio Component Hookups

Since this speaker system incorporates its own internal
amplifier and preamplifier, you can also connect an
audio component, such as a CD player.

CD front left speaker

Do not connect an amplified audio source. The combined
amplification from the component and the speaker's internal
amplifier may damage the speakers.

For the best possible sound (or if your TV only has a monaural AUDIO OUT jack, or no AUDIO OUT jacks)

Coimect the speaker system directly to your VCR or cable box.
The following connections suppress noise from the TV and let
you enjoy high quality sound.

1 Connect your VCR or cable box to the 1 IN jacks on the left

front speaker.

2 Connect your TV to the 1 OUT jacks on the left front speaker.

Make sure you use the 1 or 2 IN jacks that correspond to the
VIDEO IN jack you are using on your TV set (i.e., VIDEO 1).

Dolby Pro Logic Surround

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, left­to-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.

Dolby Surround

Encoding and decoding system of Dolby
Surround sound for consumer use. Dolby
Surround decodes the extra channels on the
Dolby Surround-encoded sound tracks of
movie videos and TV programs and produces
sound effects and echoes that make the action
seem to envelop you.
