• This subwoofer employs Advanced Yamaha Active

Servo Technology II, which Yamaha has developed for

the production of higher quality, super-bass sound.

(Refer to page 14 for details on Advanced Yamaha

Active Servo Technology II.) This super-bass sound

adds a more realistic, theater-in-the-home effect to your

audio system.

• This subwoofer can be easily added to your existing

audio system by connecting to either the speaker

terminals or the line output (pin jack) terminals of the

amplifier.

• For effective use of the subwoofer, the subwoofer’s

super-bass sound should be matched to the sounds of

your front speakers. You can create the best sound

quality for various listening conditions by using the

HIGH CUT control and the PHASE switch.

• The Automatic power-switching function saves you the

trouble of pressing the STANDBY/ON button to turn the

power on and off.

• This subwoofer system is equipped with a linear port

unique to Yamaha that provides smooth bass response

during playback, minimizing extraneous noise not

included in the original input signal.

After unpacking, check that the following parts are

contained.

To enjoy the high sound quality, stabilize the subwoofer

using the non-skid pads.

Attach the provided non-skid pads in the four corners of the

underside of the subwoofer to prevent the subwoofer from

moving as a result of vibration, etc.

One subwoofer will have a good effect on your audio

system, however, the use of two subwoofers is

recommended to obtain more effect.

If using one subwoofer, it is recommended to place it on

the outside of either the right or the left front speaker. (See

fig. .) If using two subwoofers, it is recommended to

place them on the outside of each front speaker. (See

fig. .) The placement shown in fig. is also possible,

however, if the subwoofer is placed directly facing the

wall, the bass effect may suffer due to cancellation of direct

and reflected sounds. To prevent this from happening,

place the subwoofer at an angle, as in fig. or .

Note

There may be a case that you cannot obtain enough

super-bass sounds from the subwoofer when listening

in the center of the room. This is because “standing

waves” have developed between two parallel walls and

cancel the bass sounds.

In such a case, place the subwoofer at an oblique angle

to the wall. It also may be necessary to break up the

parallel surfaces by placing bookshelves, etc. along the

walls.

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.

toque el puerto, ya que podría causar lesiones personales o la

unidad podría averiarse.

• Nunca coloque un objeto frágil cerca del puerto YST de esta

unidad. Si el objeto se cae o se vuelca debido a la presión del aire,

podría provocar averías en la unidad o lesiones personales.

• No abra nunca la carcasa. Podría provocar una descarga eléctrica,

ya que esta unidad es de alto voltaje. También podría provocar

lesiones personales o averiar la unidad.

• Si utiliza un humidificador, es muy importante evitar la

condensación dentro esta unidad. Para ello, deje siempre suficiente

espacio alrededor de esta unidad y evite el exceso de

humidificación. La condensación podría causar un incendio,

averiar la unidad o producir una descarga eléctrica.

• Las frecuencias de ultragraves generadas por esta unidad pueden

hacer que el tocadiscos emita un sonido de aullido. En este caso,

aleje la unidad del tocadiscos.

• La unidad podría averiarse si se escucharan continuamente ciertos

sonidos en el nivel máximo de volumen. Por ejemplo, si se

escuchan ondas sinusoidales de 20 Hz - 50 Hz con el disco de

prueba, sonidos graves de instrumentos electrónicos, etc.; o

cuando la aguja del tocadiscos toque la superficie de un disco,

reduzca el nivel de volumen para evitar que se dañe el equipo.

• Si se escuchan sonidos distorsionados (por ejemplo sonidos raros,

“golpeteos” o “martilleos” intermitentes) provenientes de la

unidad, baje el nivel del volumen. Si se reproducen pistas de

sonido de películas de baja frecuencia, sonidos con bajos fuertes o

música de similares características a volumen muy alto, se podría

averiar el sistema de altavoces.

• La vibración generada por frecuencias ultragraves podría

distorsionar las imágenes de un televisor. En este caso, aleje el

sistema del televisor.

• No limpie la unidad con disolventes químicos: podría dañar el

acabado. Utilice un paño limpio y seco para la limpieza.

• No deje de leer la sección “LOCALIZACIÓN DE AVERÍAS”

donde se dan consejos sobre los errores de utilización antes de

llegar a la conclusión de que la unidad está averiada.

• Instale esta unidad cerca de la toma de CA y donde se pueda

alcanzar fácilmente la clavija de alimentación.

• La instalación en un lugar seguro es responsabilidad del

propietario. YAMAHA no se hace responsable de ningún

accidente provocado por una instalación incorrecta del

altavoz.

PRECAUCIÓN: Leer este manual de instrucciones antes de

poner la unidad en funcionamiento.
