Installation: Install in accordance with the manufacturer's
instructions.
Power Sources: This product should be operated only from the
type of power source indicated by the marking situated on the rear
panel. If you are not sure of the type of power supply to your
home,consult your product dealer or local power company.
Grounding or Polarization: The appliance is not required to be
grounded. Ensure the plug is fully inserted into the wall outlet or
extension cord receptacle to prevent blade or pin exposure. Some
versions of the product are equipped with a power cord fitted with
a polarized alternating line plug (a plug having one blade wider
than the other). This plug will fit onto the power outlet only one
way. This is a safety feature. If you are unable to insert the plug
fully into the outlet,try reversing the plug. If the plug should still
fail to fit,contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug. When
using an extension power-supply cord or a power-supply cord
other than that supplied with the appliance,it should be fitted with
the appropriate molded plugs and carry safety approval appropriate
to the country of use.
Power Cord Protection: Power-supply cords should be routed so
that they are not likely to be walked on or pinched by items placed
on or against them,paying particular attention to cords at plugs,
convenience receptacles and the point where they exit from the
appliance.
Overloading: Do not overload wall outlets,extension cords or
integral convenience receptacles,as this can result in a risk of fire or
electric shock.
Water and Moisture To reduce the risk of fire or electric shock,
do not expose the product to rain or excessive moisture such as in
a sauna or bathroom. Do not use this product near water for

Breaking-in period
The drivers used in the Bolzano Villetri loudspeakers are complex
mechanical devices and require on run-in period before they deliver
their best performance. They must get adapted to the
temperature and humidity conditions of their environment. This
breaking period depends on the encountered conditions and can
last several weeks. In the order to shorten this period,we advise
you to let your loudspeakers operate no less than twenty hours at
the medium level,playing standard musical programmers,but with
a large amount of bass.
Once the components of the loudspeakers are completely
stabilized,it is possible to enjoy the real performance of your
Bolzano Villetri loudspeakers.

you may choose.
Audio system configuration
Any pair of Bolzano Villetri floorstanding loudspeakers can be
used as stereo pairs in home audio system.
Connections
Follow the steps below to setup and connect your speakers to
your AV equi pment.
Always turn off your amplifier before connecting any cables or
altering any connections.
Always use cables of the same type and length for left and right
speakers.
For the perfect sound experience,the right speaker must be
connected to the output terminal marked "R" or "Right" on your
amplifier and the left speaker to the terminal marked "L" or "Left".
The red terminal (+) on the amplifier should be connected to
the red terminal (+) on the speaker,and the black terminal (-) on
the amplifier should be connected to the black terminal (-) on the
speaker (Fig. 2)
The same guidelines apply irrespective of the number of speakers
in your sound system: speakers positioned to the right must be
connected to the amplifier output terminal marked "R" or "Right",
and any to the left must be connected to "L" or "Left".
You must ensure that the cable ends are firmly pushed into the
terminals,and that there are no loose wires,which could cause a
short circuit and damage the amplifier (Fig. 3)
Always screw the terminal caps down tightly to optimize the
connection and prevent rattles.
Ask your dealer for advise when choosing cable.

Positioning
It is important to place your speakers in the right position in the
room. Correct set-up and tuning will provide a significantly better
sound experience. Follow some useful pieces of advice below to
maximize the performance of your speakers.
1. Front Speakers should be placed symmetrically in the relation
to your display.
2. The Center Speaker should be placed ideally underneath your
display.
3. Rear Speakers can be difficult to place as you often have no
room behind where you choose to sit.
4. Subwoofer can be placed anywhere in your room as
subwoofers are omni-directional. We recommend that it is placed
near the central channel loudspeaker.
5. Distance from walls:
The system work well when
placed 50 cm from a rear wall,
preferably greater distance. This
distance depends on your
installation conditions.
6. Use your own judgment and
the tastes to fine tune the
systems.

Hi Level In
These inputs are designed to accept an amplified signal from the
speaker outputs of a receiver,power amp or other device not
equipped with line level outputs.
Hi Level Out
The original amplified signal from your source is present at these
outputs,for connection to the existing left and right speakers
(direct connection from amplifier is the best).
Line In
The RCA-type jack of your Subwoofer is designed to accept a line
level signal from a receiver,pre-amp,surround sound decoder,
television or similar device. When using a single line level output
from another unit,a Y connector (not included)should be used to
send the signal to both the left and right inputs.
Hi Level Connections
Here the signal is already amplified
as it leaves the receiver/amplifier.
The speaker terminals of this unit
are connected to the hi level inputs
of the Subwoofer. The left and right
speakers receive the original
amplified signal from the Subwoofer
hi level outputs.
Line Level Connections
In this example,the pre-amp
outputs of a stereo receiver are
connected to the Subwoofer line
inputs.
Dedicated Subwoofer Connections
Many surround sound decoders,
home theater processors and
audio/video receivers are equipped
with a dedicated subwoofer line
output. In this case,the signal is
already processed and does not
need to return to the system or
other speakers. Connect this line

Using the Controls
The subwoofer is equipped with both a Power switch and an
Auto On switch. In order to function,the Power switch must be
turn on,indicated by the green color of the LED. The Auto On has
two Positions: ONThe subwoofer is on at all time and ready to
play program material. AUTOON As long as no audio signal is
received,the subwoofer is in Standby mode to conserve power.
When an audio signal is sensed,the subwoofer will switch itself
into the fully On mode and begin playing the program material.
When a period of about 2minutes goes by during which no signal
is sensed,the subwoofer will return to Standby mode.
If you plan to be away for an extended time,or if the subwoofer
will not be used,you may wish to turn off the Power switch.
Power
Subwoofer Volume
The level control adjusts the volume of the subwoofer. Once set,
the level control should not require further adjustment. Begin with
the level control at the minimum position. Slowly increase the level
until you can hear the subwoofer. A subwoofer playing too loud
can give your system a muddy sound,so be sure to balance the
subwoofer carefully with you other speakers. Output level is
relative and can be different from location to location. Always
return to the normal listening location to evaluate any setting
changes.
Low pass
The crossover frequency control determines the highest frequency
at which the subwoofer reproduces sounds. It can be adjusted
from 26 Hz to 140Hz in accordance with the sound of the main
systems.
