1. - INTRODUCTION
The
new
DP
product
line,
which
has
been
developed
and
manufactured
by
Musicson,
conceals
an
important
technological
step
forward
in
sound
reinforcement. Its applications range from live concerts to recorded music
in open spaces or closed rooms.
Musicson's engineers have used state-of-the-art last generation software
tools
in
order
to
simulate
acoustic
elements
as
well
as
to
produce
the
corresponding prototypes.
The different frequency ways that form the DP-series have been optimised,
even before producing the prototypes, through several simulation processes.
In
order
to
develop
the
low-
frequency
units,
a
special
care
has
been
taking,
not
only
simulating
the
differences
in
frequency
response
and
performance, but also further factors have been taken care of for the first
time.
Maximum excursion of the mobile parts of the speakers have been optimised
by acting on the geometry of the enclosures, resonance frequency, length and
width of wave-guiding every elements that form, for example, a folded horn
unit.
On top of this, very concrete filters have been used within the ISP-1014 and
the
ISP-2022
dynamics
processors
in
order
to
achieve
an
optimal
frequency
response
and
a
minimum
loudspeaker
excursion,
resulting
in
a
reduced
mechanical fatigue of these elements.
On the other hand, equally important factors, such as the sound pressure
level,
acoustic
power,
extreme
current
and
voltage
values
at
the
speaker
poles, speed and acceleration of the electro acoustic elements and the air
moved within the enclosures and through the vents, etc.
The simulation software has also been used in order to optimise high and
mid-
frequency
band
functioning,
something
almost
unthinkable
some
years
ago.
A
linear
frequency
response,
effective
bandwidth,
sound
pressure
and
also factors such as directivity, horizontal and vertical spread, possible
frequency overlapping produced through horns and phase plugs, depending on
the distance to the audience, are all factors that have received careful and
in-depth attention.
In
an
ongoing
step,
all this information has been checked and adjusted
with the first prototypes through different audio analysis software.
All this has resulted in the final development of the DP sound systems,
formed
by
four
different
enclosures
and
two
signal
processors,
power
control,
that
are
designed
to
perfectly
fit
together
for
an
optimum
performance, frequency response and functional parameters.
