Assembly; Positioning The Speakers; Connections - Lumina Sonus Faber Manuel Du Propriétaire

Some loudspeakers can be fitted with a thread-tensioning mask, to be found in the accessories kit.
Refer to Section 6 (Illustrations) and carefully follow these instructions:
• Insert the pins of the bars of the string grille in the relevant guides, starting from the bottom of the speaker;
• Stretch the elastic bands of the mask until you are able to insert the pins of the mask bars into the relevant
guides in the upper part of the speaker;
If you wish to disassemble the string grille, first pull the bar pins out starting from the top of the speaker, then
move to the base.
While mounting or removing the thread-tensioning mask as described above, be careful not to
damage the front part of the speaker.

3.2 ASSEMBLY

Carefully refer to the drawings in Section 6 (Illustrations).

3.3 POSITIONING THE SPEAKERS

These loudspeakers are designed to be easily inserted within the listening environment. In order to obtain
excellent performance, refer to the images in Section 6 (Illustrations).
The conformation of the listening environment and the loudspeakers' positioning can affect the entire audio
system's performance.
For example, a room with irregular shape can improve the response within the listening environment, since they
limit the formation of standing waves, while a room with a parallelepiped shape is potentially more suitable to
generate balanced sound images.
The presence of carpets and curtains positively affect the acoustics of the environment, contributing to the
absorption of the first reflections and the lowering of reverberation.
There are no fixed and universally applicable rules for every environment. Nevertheless, a good approach is
to start by dividing the listening environment's floor plan, assuming a rectangular shape, into three areas with
equal surface.
Referring to the drawing in Section 6 (Illustrations), we suggest to position the loudspeakers on the first line (A)
suitably distanced from the side walls, and to position the listening point on the second line (B).
In this way, undesired acoustic effects, deriving from intense first reflections and environmental resonance,
which would be generated with loudspeakers positioned in proximity of the walls and corners of the room, are
minimized.
The loudspeakers' axis should converge toward the listening position by crossing over top of it, thus creating the
"equilateral triangle" stereophonic configuration. This measure, which consists in positioning the loudspeakers
in such a way as to literally point them towards the listener's ears, allows significant improvement in the focus
of the stereophonic image.
Given that the illustrated procedure, which is aimed at creating almost perfect listening conditions, cannot be
applied by all of our customers due to objective problems linked to the organization of the living environment, it is
recommended to position the two loudspeakers away from the corners of the room, and at a distance of at least
1 m from the back wall. The two loudspeakers should be at least 1.8 meters apart from each other.
The listening point should be at a height of approximately 1.1 meters off the ground.
The distance between the loudspeakers themselves, and between the loudspeakers and the listening point, can
be subsequently adjusted as desired.
If the loudspeakers are to be positioned on a shelf, distancing is at least one and a half meters and
surfaces at equal height is recommended.

3.4 CONNECTIONS

After the loudspeakers have been positioned, they can be connected. Refer to the images in section 6.
The connections must be made with the equipment turned off!
