A. Control de frecuencia
El control de frecuencia cambia el umbral superior de la frecuencia del altavoz de
graves. Su intervalo efectivo va desde 40 a 140 Hz a un régimen de 12 dB / 24 dB
por octava. El control de frecuencia debe ajustarse para obtener la integración
más suave entre los altavoces principal/satélite y los altavoces de graves.
El giro en el sentido de las agujas del reloj incrementa la frecuencia de corte y en
sentido contrario la decrementa.
1. Frecuencia de cambio ideal. Respuesta plana.
2. El punto de frecuencia de cambio fijado demasiado bajo causa una
depresión en la respuesta combinada.
3. El punto de frecuencia de cambio fijado demasiado alto causa una cresta
en la respuesta combinada.
B. Controllo di fase
El Controllo di fase debe estar normalmente en 0˚, pero algunas veces se puede
obtener un mayor nivel de salida en la posición de 180˚, especialmente cuando el
altavoz de graves esta alejado de los altavoces satélite.
C. Control de nivel
El control de nivel ajusta el nivel de salida del altavoz de graves en relación con
los altavoces AV o satélites. El giro hacia la derecha incrementa el nivel de salida y
hacia la izquierda lo disminuye.
D. Conmutador Auto/Manual
Activa / desactiva el silenciamiento de la entrada al subwoofer.Al colocar este
conmutador en la posición Auto, el subwoofer silenciará la entrada
automáticamente si éste se mantiene inactivo durante alrededor de 45 minutos, y
reanudará su funcionamiento apenas aparezca una señal. Si se coloca en Manual, la
unidad nunca será silenciada, incluso cuando no haya una señal de entrada.
E. Tierra Si/No
Mejora la compatibilidad. Se usa para romper posibles lazos de tierra que causen
zumbidos audibles.
F. Musica/Cine
Este conmutador selecciona una de estas caracteristicas: Musica se selecciona
para obtener graves profundos y limpios; Cine se selecciona para conseguir
impacto en las peliculas.
G. Rampa
Usado para ajustar la transicion entre altavoces y subgrave.

REMEDIO
Compruebe que el altavoz de graves está conectado a la red y que los interruptores están
activados
Compruebe los fusibles o disyuntores de la red que puedan afectar a la falta de
funcionamiento del altavoz
Póngase en contacto con el proveedor del equipo para obtener asesoramiento.
Asegúrese de que todo el equipo está conectado
Compruebe y ajuste el control de nivel.
Compruebe que las clavijas de salida del equipo principal están correctamente conectadas y
ajústelas para proporcionar potencia suficiente para que funcione el altavoz de
graves.
Compruebe que todas las conexiones entre el altavoz de graves y el equipo
principal (fuente) están correctas y ajústelas según sea necesario.
Póngase en contacto con el proveedor del equipo para obtener asesoramiento.
Puesto que el sonido de baja frecuencia producido por el altavoz de bajos
no es direccional, puede ser colocado en cualquier lugar de la habitación,
aunque no debe ser colocado demasiado cerca del oyente. Si es posible,
pruebe el altavoz en diferentes ubicaciones para encontrar el lugar en el
que no se produce reverberación del sonido.
Se suministra un cable de conexión a la red de acuerdo con los requisitos
del país y las regulaciones relativas a la toma de tierra.
Altavoces frontales capaces de producir frecuencias de amplia gama.
A. Línea de nivel - conectada al bucle del procesador del
amplificador.
B. Entradas de líneas de nivel - conectadas a la salida de
altavoces de graves del amplificador por medio de cable sencillo o
en Y.

FAULT
Mains indicator light does not come on.
If the mains indicator light still does not come on.
If the mains indicator light is on but no sound
comes from the subwoofer.
If there is still no sound.
REMEDY
Check that the subwoofer is plugged into the mains supply and that any switches are on.
Check any fuses (including the plug) or circuit breakers on the mains supply which may effect the
power to the subwoofer.
Contact your dealer for further advice.
Ensure that all equipment is switched on.
Check and adjust the level control.
Check that the output sockets on the source equipment are correctly switched and
adjusted to provide sufficient level to drive the subwoofer.
Check that all connections between the subwoofer and the source equipment are
correct and adjust as necessary.
Contact your dealer for further advice.
As the sub-bass (low frequency) sound produced by the subwoofer is
non-directional it can be positioned almost anywhere in the room,
although it should not be placed too close to the listener. If possible
try the subwoofer in different positions to find the best place for a
boom-free sound.
Front speakers full range - speakers capable of producing full
frequency range.
A. Line Level - connected to amplifier processor loop.
B. Line level inputs - connected to subwoofer output on amplifier
by single (C1) or ‘Y’ (C2) cable.
A. Frequency Control
The frequency control changes the upper cut-off frequency of the
subwoofer. Its effective range is from 40Hz to 140Hz at a rate of
12dB/24dB per octave.The frequency control should be adjusted to
achieve the smoothest integration between the main/satellite speakers and
the subwoofer.
Clockwise rotation will increase the cut-off frequency and
anti-clockwise rotation will decrease the cut-off frequency.
1. Ideal Crossover - Flat Response.
2. Crossover point set too low - Causes Dip in combined response.
3. Crossover Point set too high - Causes hump in combined response.
B. Phase Control
The phase control will normally be set at 0° but more output level can
sometimes be achieved in the 180° position, particularly when the
subwoofer is far away from the satellite speakers.
C. Volume Control
The volume control adjusts the output level of the subwoofer in relation
to the satellite or AV speaker output level. Clockwise rotation to increase
the output level or anti-clockwise to decrease the output level.
D. Auto/Manual Switch
It enables / disables your subwoofer in standby (mute). Setting this switch
to Auto position, the subwoofer will go to standby automatically if idle for
45 minutes. It resumes working immediately after an input signal is
received. If Manual is set, the unit will not go to standby even when there
is no signal input.
E. Ground In/Out
Enhances compatibility. Used to break possible earth loops which cause
audible hum.
F. Music/Cinema
This switch selects one of two characteristics: Music is selected to give
deep, clean bass; Cinema is selected to give cinematic impact.
G. Slope
Used to adjust transition between speakers and subwoofer.
