iii CAUTION
1
To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
2
Install the speakers in a cool, dry, clean place – away from
windows, sources of heat, sources of excessive vibration, dust,
moisture or cold. Avoid sources of electrical humming (e.g.,
transformers and motors). To prevent fire or electric shock,
do not expose the speakers to rain or water.
3
To prevent the enclosure from warping or discoloring, do not
expose the speakers to direct sunlight or excessive humidity.
4
Avoid installing the speakers where foreign objects may fall
onto them and/or where they may be exposed to liquid
dripping or splashing.
5
Do not place the following objects on top of the speakers:
– Other components, as they might damage or discolor the
surface of the speakers;
– Burning objects (e.g., candles), as they might cause fire,
damage to the speakers or personal injury;
– Containers of liquid, as they might spill and cause electric
shock to the user or damage to the speakers.
6
Do not place the speakers where they are liable to be knocked
over or struck by falling objects. Stable placement will also
ensure better sound.
7
Placing the speakers on the same shelf or rack as the
turntable can result in feedback.
8
Secure placement or installation is the owner’s responsibility.
YAMAHA is not liable for accidents caused by improper
placement or installation of speakers.
9
If you note distortion, reduce the volume control on your
amplifier. Do not drive your amplifier to the point of
“clipping”. Otherwise, the speakers may be damaged.
10 When using an amplifier with a rated output power higher
than the nominal input power of the speakers, care should be
taken not to exceed the speakers’ maximum input.
11 Do not clean the speakers with chemical solvents as this
might damage the finish. Use a clean, dry cloth.
12 Do not attempt to modify or fix the speakers. Contact
qualified YAMAHA service personnel when service is needed.
Do not open the cabinet under any circumstances.
13 Please read the “Troubleshooting” section regarding common
operating errors before concluding that the speakers are
faulty.
For the NX-SW150
1
Do not operate this unit upside down. It may overheat,
possibly causing damage.
2
Do not use excessive force on switches, controls or connection
wires. When moving this unit, first disconnect the power plug
and the wires connected to other equipment. Never pull the
wires themselves.
3
Since this unit has a built-in power amplifier, heat radiates
from the rear panel. Place the unit away from walls, allowing
at least 20 cm of space above, behind and on both sides of the
unit to prevent fire or damage. Furthermore, do not position
the unit with the rear panel facing down on the floor or other
surfaces.
4
When using a humidifier, be sure to avoid condensation
inside this unit by allowing enough space around the unit and
avoiding excess humidification. Condensation might cause
fire, damage to the unit, or electric shock.
5
Do not cover the rear panel of this unit with a newspaper,
tablecloth, curtain, etc. to avoid obstructing heat radiation. If
the temperature inside the unit rises, it may cause fire,
damage to the unit, or personal injury.
6
Do not plug this unit into a wall outlet until all connections
are complete.
7
The voltage to be used must match that specified on the rear
panel. Using this unit with a voltage higher than specified is
dangerous and may cause fire, damage to the unit, or
personal injury. YAMAHA is not responsible for damage
resulting from use of this unit with a voltage other than
specified.
8
To prevent damage from lightning, disconnect the AC power
plug during electric storms.
9
Super-bass frequencies reproduced by this unit may cause a
turntable to generate audio feedback. In this case, move the
unit away from the turntable.
10 This unit may be damaged if certain sounds are continuously
output at high volume level. For example, if 20Hz–50Hz sine
waves from a test disc or bass sounds from an electronic
instrument, etc. are continuously output, or if a turntable
stylus touches the surface of a disc, reduce the volume level to
prevent the unit from being damaged.
11 If you hear distorted noise (i.e., unnatural, intermittent
“rapping” or “hammering” sounds) from this unit, reduce
the volume level. Extremely loud movie soundtrack low
frequency, bass-heavy sounds, or similarly loud popular
music passages can damage the speaker system.
12 Vibration generated by super-bass frequencies may distort
images on a TV. In this case, move the unit away from the TV
set.
13 When disconnecting the power cord from the wall outlet,
grasp the plug; do not pull the cord.
14 When you plan not to use this unit for a long period of time
(i.e., vacation, etc.) disconnect the AC power plug from the
wall outlet.
15 Do not place much pressure against the subwoofer net. It may
break the net or the unit may fall, resulting in injury.
16 Do not place anything fragile beside the subwoofer. The air
pressure produced by the subwoofer may break the objects
and cause malfunction or injury.
FOR CANADIAN CUSTOMERS
To prevent electric shock, match wide blade of plug to wide
slot and fully insert.
This Class B digital apparatus complies with Canadian
ICES-003.
