About this manual

The SA-VE155 is a 5.1 channel speaker system consisting of 
two front speakers, one center speaker, two surround speakers, 
and one subwoofer. It supports Sony Digital Cinema Sound, 
Dolby* Pro Logic, and Dolby Digital etc., and is thus geared 
towards the enjoyment of movies.

*    “Dolby” and the double-D symbol are trademarks of Dolby 

Laboratories.

Precautions

On safety

•  Before operating the system, be sure that the operating 

voltage of the system is identical with that of your local 
power supply.

•  The unit is not disconnected from the AC power source 

(mains) as long as it is connected to the wall outlet, even if 
the unit itself has been turned off.

•  Unplug the system from the wall outlet if it is not to be used 

for an extended period of time. To disconnect the cord, pull 
the cord by grasping the plug. Never pull the cord itself.

•  Should any liquid or solid object fall into the system, unplug 

the system’s power cord and have the system checked by 
qualifi ed personnel before operating it any further.

•  AC power cord must be changed only at the qualifi ed service 

shop.

On operation

•  Do not drive the speaker system with a continuous wattage 

exceeding the maximum input power of the system.

•  If the polarity of the speaker connections are not correct, 

the bass tones will be weak and the position of the various 
instruments obscure. 

•  Contact between bare speaker wires at the speaker terminals 

may result in a short circuit.

•  Before connecting, turn off the amplifi er to avoid damaging 

the speaker system.

•  The speaker grille cannot be removed. Do not attempt to 

remove the grille on the speaker system. If you try to remove 
it, you may damage the speaker.

•  The volume level should not be turned up to the point of 

distortion.

If you encounter color irregularity on a 
nearby TV screen

This speaker system is magnetically shielded to allow it to be 
installed near a TV set. However, color irregularities may still 
be observed on certain types of TV sets.

If color irregularity is observed...

c

  Turn off the TV set, then turn it on again after 15 to 30 

minutes.

If color irregularity is observed again...

c

  Place the speakers further away from the TV set.

If howling occurs

Reposition the speakers or turn down the volume on the 
amplifi er.

On placement

•  Do not set the speakers in an inclined position.
•  Do not place the speakers in locations that are:  

— Extremely hot or cold
— Dusty or dirty
— Very humid
— Subject to vibrations
— Subject to direct sunlight

•  Use caution when placing the speaker on a specially 

treated (waxed, oiled, polished, etc.) fl oor, as staining or 
discoloration may result.

On cleaning

Clean the speaker cabinets with a soft cloth lightly moistened 
with a mild detergent solution or water. Do not use any type 
of abrasive pad, scouring powder or solvent such as alcohol or 
benzine.

If you have any questions or problems concerning your speaker 
system, please consult your nearest Sony dealer.

Hooking up the system

Connect the speaker system to the speaker output terminals of 
an amplifi er (

A

).

Make sure power to all components (included the subwoofer) 
is turned off before starting the hook-up.  

Notes (

B

)

•  Make sure the plus (+) and the minus (–) terminals on the 

speakers are matched to the corresponding plus (+) and 
minus (–) terminals on the amplifi er.  

•  Be sure to tighten the screws of the speaker terminals 

securely as loose screws may become a source of noise.  

•  Make sure all connections are fi rm. Contact between bare 

speaker wires at the speaker terminals may cause a short 
circuit.

•  For details regarding the connections on the amplifi er side, 

refer to the manual that was provided with your amplifi er. 

Tip

Black or black striped wires are minus (–) in polarity, and 
should be connected to the minus (–) speaker terminals.

Positioning the speakers 

Location of each speaker (

C

)

Each speaker should face the listening position. Better 
surround effect will result if all speakers are set at the same 
distance from the listening position. 
Place the front speakers at a suitable distance to the left and 
right of the television. 
Place the subwoofer on either side of the television.  
Place the center speaker on the top-center of the TV set. 
The placement of surround speakers greatly depends on the 
confi guration of the room. The surround speakers may be 
placed on both sides of the listening position 

A

 or behind the 

listening position 

B

.  

Setting the speakers

To prevent speaker vibration or movement while listening, 
attach the supplied foot pads to the bottom four corners of the 
front speakers, center speaker and surround speakers (

D

).

Setting the center speaker (

E

)

Set the center speaker fi rmly on top of the TV set, making sure 
it is completely level.  

Setting the speakers using the optional speaker 
stands (

F

)

For greater fl exibility in the positioning of the speakers, use the 
optional WS-FV11 or WS-WV10D speaker stand (available 
only in certain countries).

To hang the front, center and surround speakers 
with a hook (not supplied) on the wall (

G

)

You are responsible for the proper selection and use of 
mounting hardware that you purchase at hardware stores, and 
for the proper and safe mounting of the speakers.

Tip

The height of the front speakers should be adjusted to about the 
center of the TV screen (

H

).

Setting the amplifi er

When connecting to an amplifi er with internal multi channel 
decoders (Dolby Digital, DTS**, etc.), you should use the 
setup menus for the amplifi er to specify the parameters of your 
speaker system.
See the table below for the proper settings.  For details on the 
setting procedure, refer to the manual that was provided with 
your amplifi er.

Speaker setup

For                                                  Set to 

Front speakers                                      SMALL

Center speaker                                     SMALL

Surround speakers                                SMALL

Subwoofer                                            ON (or YES)

If you use the amplifi er with adjustable crossover frequency, 
it is recommended to select 150 Hz (or close to this fi gure) as 
the crossover frequency for your front, center and surround 
speakers.

Listening to the sound (

I

)

First, turn down the volume on the amplifi er. The volume 
should be set to minimum before you begin playing the 
program source.

1

    Turn on the amplifi er and select the program 

source.

2

    Press POWER on the subwoofer.
 

The POWER indicator on the subwoofer 
lights up green. 

3

    Play the program source.

Adjusting the subwoofer (

I

)

Rotate LEVEL to adjust the volume.

Set the volume level to best suit your pref er ence 
according to the program source.

Notes

•  Some amplifi er functions for enhancing the sound may cause 

distortion in the subwoofer. If such distortion occurs, turn off 
those functions.  

•  To enjoy high-quality sound, do not turn the subwoofer 

volume too high.

Troubleshooting

Should you encounter a problem with your speaker system, 
check the following list and take the indicated measures. If the 
problem persists, consult your nearest Sony dealer. 

There is no sound from the speaker system.  

• Make sure all the connections have been correctly 

made. 

• Make sure the volume on the amplifi er has been 

turned up properly.

• Make sure the program source selector on the 

amplifi er is set to the proper source.

• Check if headphones are connected. If they are, 

disconnect them.

There is distortion in the subwoofer sound 
output.

• Check if any sound-enhancing functions have been 

activated on the amplifi er. If they have, turn them 
off.

There is hum or noise in the speaker output.

• Make sure all the connections have been correctly 

made.

• Make sure none of the audio components are 

positioned too close to the TV set.

The sound has suddenly stopped.

• Make sure all the connections have been correctly 

made. Contact between bare speaker wires at the 
speaker terminals may cause a short circuit.

Protection circuit is contained in the satellite speakers. If the 
speakers are overdriven for certain minutes, the protection 
circuit will automatically reduce the sound volume. In the case, 
stop the program source for 2-3 minutes. Before playing the 
source again, turn down the volume level of the amplifi er.
