Installation
The input sockets ensure reliable
multipurpose connections for stripped
cables as well as for plugs. It is
imperative to respect the connector
polarity of both the loudspeaker
and amplifier. The positive terminal
"+" must be connected to the
corresponding (matching) amplifier's
terminal and the negative terminal
" " to the negative terminal (fig. A).
Stereo image, soundstaging and
bass perception would be seriously
compromised if these conditions were
not respected. Don't underestimate
the importance of the cable: make
sure you chose the appropriate
section and length. Let your retailer
advise you.
Mounting
This should be carried out after all
of the cables have been fitted. We
recommend that you use a marked
cable in order to conserve the polarity
of the speakers (+/-).
• Cut the dry wall using the template
supplied (fig. B). Be sure to check
that this is perfectly vertical using a
spirit level before you begin cutting.
• Check construction plans of your
room to make sure that you are
not drilling into a pipe, an electrical
cable or any other specialised
installations behind the wall.
Fixing
The loudspeaker is firmly fixed into
the wall using a system of clamps.To
achieve this, place the speaker into
the cut-out and tighten the fixing
screws in a clockwise direction using a
cross-head screwdriver (fig. C, D, E).
Paint
If you wish, you can paint your
speaker to match your room. We
advise that you paint the grille and the
housing of the speaker separately. For
the frame: remove the grille and place
the paint mask in position to protect
the drivers.
Speakers placement
The Custom line loudspeakers have
been engineered to deliver the most
faithful sound reproduction, whether
they are used for music or home
cinema. In order to enhance their
performance, to guarantee a high
quality of listening, sound image
and tone balance, it is important to
note the following basic rules. The
listening area must be located at
the summit of an equilateral triangle
whose two other points of insertion
are determined by the position of
each speaker. Nevertheless it is
possible to modify these distances to
find an ideal compromise according
to the particular disposition of the
room (fig. F).
Each loudspeaker must be placed
at the same height and on the same
floor plan. The tweeter should be
at the same height as the listener's
ear, when the listener is in his usual
listening area (fig. G).
Surround and center speakers
placement
The soundtrack mix for a film or music
encoded in multichannel format is
very complex and allows the listener
to benefit from a wide range of special
sound effects, which require the use of
effect channel speakers. In order to
obtain a realistic 3D soundstage,
the placement of the speakers is
decisive, even when confronted with
a restrictive disposition of the listening
room. For enhanced performances,
the following elements should be
noted. Central channel speakers
should be placed close to the TV-
screen to obtain a proper placement
and a realistic reproduction of the
dialog (fig. Ha). They could be
placed below or above the TV-screen
if your TV-unit permits. If a standart
projection screen is used, the central
channel speaker must be placed
under the screen. If an acoustically
transparent projection screen is used,
the central channel speaker can be
placed behind and at the bottom of
the screen. Avoid placing the effect
speakers too far from the listening
area otherwise the sound perception
will be altered. In order to obtain
surround effects, with great sound
density we advise you to place the
speakers against the sidewalls on
each side of the listening room (fig.
Hb, Hd). You can use an in-ceilling
surround speakers (fig. Hc) or for
back center surround channel for 6.1
or 7.1 configuration.
Tweeter adjustment
To carry out adjustments, use the
switch level located on the front baffle
of the speaker as follows (fig. I).
Adjust the tweeter facing the listening
area (except IC 105) (fig.J).
