Setup tips
APU protection
Amina loudspeakers must be used with
an APU protection device or another
protection device, approved by Amina.
Please refer to the instructions supplied
with the APU devices and full warranty
information for further details.
Installation Backboxes
Amina loudspeakers have been designed
for optimum sound quality when
installed with the Amina BackboxCV. We
recommend that they are used wherever
possible in a cavity type installation. If
our basic fixing block kit is used you may
find that the low/mid frequencies are
reproduced less accurately, but any effect
will be very much installation specific.
When installed into solid walls or ceilings
using the Amina BackboxSW, you may
find that your speaker reproduces slightly
less low frequency output compared to a
BackboxCV installation. Also, depending
on the building construction, there may be
significant mechanical sound transmission
into adjacent rooms/properties (see inside
front cover).
Wall or Ceiling Placement
Amina loudspeakers are suitable for both
wall and ceiling installations. When the
most uniform audio coverage in a room is
required, space the loudspeakers evenly
in the ceiling. However, if the room has
a height greater than 6m (19’), Amina
suggests installing them in the walls at a
height of around 1.8m (6’).
In dedicated listening rooms where
loudspeakers are used in stereo or multi
channel systems, position them in the walls
so that the centre point of the speaker
is approximately 1 – 1.8m (3.5 - 6‘) from
the floor. This will give excellent results,
but don’t worry, if this is not possible
to achieve in your room, the audio
characteristics of Amina loudspeakers
make exact positioning according to stereo
5.1 and 7.1 conventions far less critical.
Audio Characteristics
Amina loudspeakers generate sound
in a similar way to an acoustic musical
instrument. The speaker’s front face is
effectively the “musical” soundboard and
the sound waves generated from it are
diffuse and are dispersed over a very
wide angle. This means that loudspeaker
positioning is far less critical than with
conventional loudspeakers. Additionally,
just like the acoustic musical instrument,
Amina loudspeakers have excellent room
filling abilities.
Amina loudspeakers are planar devices
and this feature is further enhanced when
flush mounted into your wall or ceiling.
Being planar (or flat) means that the
audio’s arrival time to the listener is the
same for all frequencies, i.e. there is very
little phase distortion. Therefore Amina
loudspeakers (and other planar devices
such as electrostatic loudspeakers) can
reproduce subtle nuances on a recording
with incredible accuracy.
In addition to the above characteristics,
the radiating surface of an Amina speaker
is very stiff and undergoes very small
amounts of movement in order to generate
high sound pressure levels. This means
that the loudspeakers are inherently
“fast” making them highly articulate
loudspeakers.
