INSTRUCTIONS
Settings
Auto on/standby system
The subwoofer features an automatic
audio signal detector. When the
"power" control is set on auto-mode,
the subwoofer will automatically
switch on as soon as an audio signal
is detected. When set to "power on",
the signal detector is disable and the
subwoofer is continuously on.
Conversely, if no signal is detected
during a period of about 3 minutes,
the detector automatically set the
subwoofer to standby mode.
If you expect not to use the subwoofer
for a long period, it is recommended
to set the power selector to "off".
In case of stormy weather, unplug the
power cable.
Quick set-up
1 - Connect the subwoofer to the
power grid (electrical outlet).
2 - Set the power selector to "on".
3 - Connect the subwoofer to the
amplifier according to one of the three
methods mentioned above.
4 - Set the "crossover" potentiometer
to intermediate position
100Hz).
5 - Set the "volume" potentiometer to
intermediate position.
Please note that the crossover is not
available when the subwoofer is
connected through the "Line Inputs
LFE".
Fine tune
1 - Adjust the bass level according to
the other used loudspeakers. In order
to find the appropriate settings, we
advise you to use as many different
music styles as possible. Bass must be
present but not too heavy.
2 - Choose the phase selector mode
(0° or 180°). The proper setting must
make you feel that the bass level is
higher and well balanced.
3 - Adjust the crossing frequency
around 100Hz. The more you lower
this frequency, the more the sound
appears to be deep and sonorous.
The higher the frequency is, the more
you will feel a dynamic bass impact.
The right settings are obtained when
all these previously stated conditions
are fulfilled.
4 - Re-adjust, if necessary, the volume
control.
5 - The settings must be adjusted each
time that the subwoofer is moved from
its initial place.
"Night" mode
(around Weak signals are increased so that the
bass is more present and satisfactory,
even at low listening levels, while
powerful signals are decreased in
amplitude. This function allows for
an excellent listening comfort in bass
response, even at very low listening
levels, and to avoid disturbing the
neighbors or others nearby.
Boost Mode
Increase of the bass level by +3dB
at 40Hz. To be used as preference or
need on multi-channel playback for
very dynamic bass.
Subsonic Mode
This filter can be very practical when
the subwoofer is placed in a small
room and-or at an angle in the room,
or if the walls of the room are thin or
not very rigid. The room may generate
an excessive sound level in the
lower bass or even cause saturation.
Vibration and unpleasant resonances
can then occur. The subsonic filter
can eliminate this annoyance and
maintain a clean and strong bass
performance.
Choice of cables
When the subwoofer is connected
to the amplifier through the "high
level" inputs, it is recommended to
use standard loudspeakers cables
with 1.5mm² minimum
When the subwoofer is connected
to the amplifier through stereo "line
level" or LFE inputs, use a RCA/RCA
shielded cable of the required length.
In every case we advise you to ask
your retailer. He will help you find the
solution meeting your needs.
