We Want You Listening For A Lifetime
YAMAHA and the Electronic Industries Associa-
tion’s Consumer Electronics Group want you to
get the most out of your equipment by playing it at
a safe level. One that lets the sound come
through loud and clear without annoying blaring
or distortion – and, most importantly, without
affecting your sensitive hearing.
Since hearing damage from loud
sounds is often undetectable until it
is too late, YAMAHA and the Elec-
tronic Industries Association’s Con-
sumer Electronics Group
recommend you to avoid prolonged
exposure from excessive volume levels.

Thank you for purchasing Yamaha’s YST-MSW8 Powered Multimedia Subwoofer. Yamaha’s Active Servo Technol-
ogy offers exceptionally high performance.
Cautions
Please read the following operating precautions before
use:
• When disconnecting the AC power cord from an AC
receptacle, hold and pull the plug, not the power cord.
• If the YST-MSW8 is not going to be used for a while,
disconnect the AC power cord from the AC receptacle.
• Always disconnect the AC power cord from the AC
receptacle before making any connections.
• The YST-MSW8 does not contain any user serviceable
parts. Refer all servicing to your Yamaha dealer.
•
Never open the cabinet.
If a foreign object drops into
the set, contact your dealer, and do not use the
YST-MSW8. Otherwise, you may cause a fire.
• Do not expose the YST-MSW8 to temperature extremes,
direct sunlight, excessive dust, humidity, or vibration.
• Position the YST-MSW8 on a level, stable surface. Do
not drop the YST-MSW8, apply excessive force to
their controls, or put heavy items on top of them.
• Since this unit has a built-in power amplifier, heat will
radiate from the rear panel. Therefore, place the unit
apart from the walls, allowing a space of at least 10 cm
(3-15/16") above, behind and on the both sides of the
unit. Also, do not position with the rear panel facing
down on the floor or other surface.
• Do not obstruct the port with your hand or a foreign
object.
• To protect the YST-MSW8 speaker, avoid microphone
feedback, continuous and excessive output from elec-
tronic musical instruments, and excessive signal dis-
tortion.
• If the YST-MSW8 is located close to fluorescent or
neon lights, a slight hum may be heard. In this case,
relocate the YST-MSW8 away from the light.
• Although the YST-MSW8 speaker is magnetically
shielded, keep floppy disks and tapes away from them.
• The YST-MSW8 may cause picture distortion when
located close to a television or computer monitor. In
this case, move them away a short distance.
• Avoid sources of hum (transformers, motors). To prevent
fire or electrical shock, do not expose to rain and water.
• Do not use force on switches, knobs or cords. When
moving the YST-MSW8, first turn the YST-MSW8 off.
• Always turn the volume control counterclockwise
before starting to play the audio source: increase the
volume gradually to an appropriate level after the play-
back has started.
Connections & Controls
Front Panel
Refer to the illustrations on page 1.
1
(power)
switch and indicator:
Press the
(power) switch to turn on the YST-MSW8; the power
indicator lights up. Press again to turn off. Turn down
the BASS and VOLUME controls before turning on
and off the YST-MSW8.
2
BASS control:
Use this control to adjust the volume
of the YST-MSW8. Turn it clockwise to increase the
volume; counterclockwise to decrease it.
3
VOLUME control:
Use this control to adjust the vol-
ume of the YST-MSW8 and other equipment con-
nected to the rear panel LINE OUT jack.
Rear Panel
4
LINE IN:
This 3.5 mm jack is used to input signals to
the YST-MSW8.
5
LINE OUT:
This jack is used to output the LINE IN
signal to the main speakers. The low frequencies of
the signal are cut before being output to the speakers.
This prevents small speakers from becoming over-
loaded.
6
AUTO STANDBY switch:
When the AUTO
STANDBY switch is in the ON position, and no input
signal is received after 5–10 minutes, the unit turns
into the standby mode automatically. (and the power
indicator dims*) When an input signal is received, the
unit is turned back on automatically. When the AUTO
STANDBY switch is in the OFF position, this AUTO
STANDBY on/off function doesn’t work.
*U.K. and Europe model only.
Note:
The unit may turn off automatically when the
input signal level is very low. If this does occur,
increase the output level from the source device and
reduce the YST-MSW8 VOLUME control accordingly.
This unit is not disconnected from the AC power
source as long as it is connected to the wall outlet,
even if this unit itself is turned off. This state is called
the standby mode.
In this state, this unit is designed to consume a very
small quantity of power.

Troubleshooting
If the speakers fail to operate normally, check the following table. It lists common operation errors and simple measures
that you can take to correct problems. If a problem cannot be corrected, or the symptom is not listed, disconnect the AC
power cord and contact your authorized YAMAHA dealer or service center for help.
Volume Adjustment
• If the YST-MSW8 is connected to an output jack for a sub-woofer on a powered main
speaker (such as the Yamaha YST-M15, YST-M8, etc.) as shown in System example 1 on
page 1, raise the VOLUME control of the YST-MSW8 to the maximum and set the
BASS control to the noon or one-o’clock position. Then, use the volume control of the
powered main speakers to adjust the overall volume.
• If the powered main speakers are connected to the YST-MSW8’s LINE OUT jack as
shown in System example 2 on page 1, set the YST-MSW8’s BASS control to the noon
or one-o’clock position and raise the volume control of the powered main speakers to
the maximum. Then, use the YST-MSW8’s VOLUME control to adjust the overall
volume.
FAULT CAUSE CURE
No sound comes from
the speakers or sub-
woofer.
The AC power cord is not properly
plugged into the wall outlet.
Insert the AC power cord firmly into the wall out-
let.
The (power) switch is turned OFF. Turn ON the (power) switch (the indicator
lights).
Connections are faulty or incomplete. Make the connections again, firmly, or use a dif-
ferent cable.
The volume is set to minimum. Turn the subwoofer VOLUME control to the right
to increase the volume.
Turn the speaker VOLUME control to the right to
increase the volume.
The level of the signal being input is
too low.
Turn up the volume on the connected component.
Noise. Connections are faulty or incomplete. Make the connections again, firmly, or use a dif-
ferent cable.
Noise is heard when the
power is turned on.
The power cord of this unit connected
to another unit’s SWITCHED AC OUT-
LET.
Connect the power cord to an UNSWITCHED AC
OUTLET.
Make sure to use the (power) switch on this
unit to turn the power on and off.
Power is not supplied
even though the
(power) switch is ON.
The power plug is not securely con-
nected.
Connect it securely.
No sound. The volume is set to 0. Turn the VOLUME control to right.
Speaker cables are not connected
securely.

Sound level is too low. Speaker cables are connected incorrectly. Connect them correctly.
A source sound with few bass frequen-
cies is played.
Play a source sound with bass frequencies. Turn
the VOLUME control to right.
It is influenced by standing waves. Relocate the subwoofer or break up the parallel sur-
face by placing bookshelves etc. along the walls.
The AUTO STANDBY
function doesn’t work.
The (power) switch is turned off. Turn the (power) switch on.
The source input signal is too low. Raise the input signal level to appropriate level.
The AUTO STANDBY
function activates unin-
tentionally.
The source input signal is too low. Raise the input signal level to appropriate level.
Power is turned on acci-
dentally when the AUTO
STANDBY function is set
to ON.
The other equipment’s hum interrupts
(i.e. computer, digital device).
Relocate the YST-MSW8 or cable wiring. Other-
wise, do not use the AUTO STANDBY function.
