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 illustrations in chapter 6.
The connections must be made with the equipment turned off!
The loudspeaker connection terminals allow you to connect cables terminated with stripped cable, forks or
banana plugs.
Loudspeaker systems with bi- or tri-wiring connection are equipped with jumpers that allow you to
implement various connection schemes. Depending on which scheme you intend to adopt, these jumpers
may have to be removed.
Proper tightening and periodic verification of the terminals will help to obtain and maintain optimal
performance.
3.4.1 STANDARD CONNECTION (SINGLE WIRING)
It consists in running the loudspeakers (usually a pair) with a single stereo amplifier, or with a pair of
monophonic amplifiers, using only one bipolar power cable for each channel. Complete the connection as
shown in the relative illustration.
