Thank you for selecting this Yamaha product.
CAUTION: Read this before operating your unit
Please read the following operating precautions before use.
Yamaha will not be held responsible for any damage and/or
injury caused by not following the cautions below.
• To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
• Install this unit in a cool, dry, clean place - away from
windows, heat sources, sources of excessive vibration, dust,
moisture and cold. Avoid sources of humming
(transformers, motors). To prevent fire or electrical shock,
do not expose this unit to rain or water.
• The voltage to be used must be the same as that specified on
the rear panel. Using this unit with a higher voltage than
specified is dangerous and may cause a fire and/or electric
shock.
• Do not use force on switches, controls or connection wires.
When moving the unit, first disconnect the power plug and
the wires connected to other equipment. Never pull the
wires themselves.
• When not planning to use this unit for a long period (ie.,
vacation, etc.), disconnect the AC power plug from the wall
outlet.
• To prevent lightning damage, disconnect the AC power plug
when there is an electric storm.
• Since this unit has a built-in power amplifier, heat will
radiate from the rear panel. Place the unit apart from the
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 with the rear panel facing
down on the floor or other surfaces.
• Do not cover the rear panel of this unit with a newspaper, a
tablecloth, a curtain, etc., in order not to obstruct heat
radiation. If the temperature inside the unit rises, it may
cause fire, damage to the unit and/or personal injury.
• Do not place the following objects on this unit:
- Glass, china, small metallic, etc.
If glass, etc., falls as a result of vibrations and breaks, it
may cause bodily injury.
- A burning candle etc.
If the candle falls as a result of vibration, it may cause fire
and bodily injury.
- A vessel containing water
If the vessel falls as a result of vibration and water spills,
it may cause damage to the speaker, and/or you may get an
electric shock.
• Do not place this unit where foreign material, such as
dripping water. It might cause fire, damage to this unit, and/
or personal injury.
• Never put a hand or a foreign object into the YST port
located on the right side of this unit. When moving this unit,
do not hold the port, as it might cause personal injury and/or
damage to this unit.
• Never place a fragile object near the YST port of this unit. If
the object falls or drops as a result of the air pressure, it may
cause damage to the unit and/or personal injury.
• Never open the cabinet. It might cause an electric shock,
since this unit uses a high voltage. It might also cause
personal injury and/or damage to this unit. If something
drops into the set, contact your dealer.
• When using a humidifier, be sure to avoid condensation
inside this unit by allowing enough space around this unit or
avoiding excess humidification. Condensation might cause
fire, damage to this unit, and/or electric shock.
• Super-bass frequencies reproduced by this unit may cause a
turntable to generate a howling sound. In such a case, move
this unit away from the turntable.
• This unit may be damaged if certain sounds are
continuously output at high volume level. For example, if
20 Hz-50 Hz sine waves from a test disc, bass sounds from
electronic instruments, etc., are continuously output, or
when the stylus of a turntable touches the surface of a disc,
reduce the volume level to prevent this unit from being
damaged.
• If you hear distortion (i.e., unnatural, intermittent “rapping”
or “hammering” sounds) coming from this unit, reduce the
volume level. Extremely loud playing of a movie
soundtrack’s low frequency, bass-hea
loud popular music passages can damage this speaker
system.
• Vibration generated by super-bass frequencies may distort
images on a TV. In such a case, move this unit away from
the TV set.
• Do not attempt to clean this unit with chemical solvents as
this might damage the finish. Use a clean, dry cloth.
• Be sure to read the “TROUBLESHOOTING” section
regarding common operating errors before concluding that
the unit is faulty.
• Install this unit near the wall outlet and where the AC power
plug can be reached easily.
• Secure placement or installation is the owner’s
responsibility. Yamaha shall not be liable for any
accident caused by improper placement or installation
of speakers.
• VOLTAGE SELECTOR
(Asia and General models only)
The voltage selector switch on the rear panel of this unit
must be set to your local main voltage BEFORE
plugging this unit into the AC main supply. Voltages are
110-120 V/220-240 V.
WARNING
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO
NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.
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. In this state, this unit is designed to
consume a very small quantity of power.

Signals of low amplitude
Air woofer
(Helmholtz resonator)
Signals
In 1988, Yamaha brought to the marketplace speaker systems utilizing YST (Yamaha
Active Servo Technology) to give powerful, high quality bass reproduction. This technique
uses a direct connection between the amplifier and speaker, allowing accurate signal
transmission and precise speaker control.
As this technology uses speaker units controlled by the negative impedance drive of the
amplifier and resonance generated between the speaker cabinet volume and port, it creates
more resonant energy (the “air woofer” concept) than the standard bass reflex method. This
allows for bass reproduction from much smaller cabinets than was previously possible.
Yamaha’s newly developed Advanced YST II adds many refinements to Yamaha Active
Servo Technology, allowing better control of the forces driving the amplifier and speaker.
From the amplifier’s point of view, the speaker impedance changes depending on the sound
frequency. Yamaha developed a new circuit design combining negative-impedance and
constant-current drives, which provides a more stable performance and clear bass
reproduction, without any murkiness.
Twisted Flare Port
Today’s bass reflex speakers use a Helmholtz resonator to improve their bass reproduction.
However when reproducing bass that is in the frequency region of this Helmholtz
resonator, air moves violently in and out through the port between the interior and exterior
of the speaker, sometimes producing noise due to the turbulent air flow at the end of the
port.
The port and the cabinet resonate at a frequency that is determined by their dimensions and
shape. On the other hand, turbulence in the air flow at the end of the port contains a broad
range of frequency components that are not present in the input signal. This noise occurs
because the broad range of frequency components includes components that match the
resonant frequencies of the port and cabinet, causing strong resonance.
The Twisted Flare Port developed by Yamaha changes the way in which the port widens
toward its end, and also adds a “twist” to suppress airflow turbulence at each end of the port
and thus prevent noise from occurring.
This eliminates the “muddy sound” and “wind noise” that until now have been
characteristic of bass reflex speakers, allowing bass to be reproduced clearly.
