The
Butterfly project includes the design of sophisticated acoustical
and mechanical simulation software, which greatly facilitates
installation, setting and aiming of Line Array elements.
V.I.P. (the
abbreviation of Vector Implementation Protocol) software was
completely developed with a high-level programming language using
powerful ‘Open GL’ graphic libraries.
The
result is a ‘tool’ able to guide PA system engineers through correct
set-up procedure from an acoustic and mechanical point of view while
fully respecting safety norms.
The risk of poor results is thus
drastically reduced. The following illustrations show the great
possibilities offered by V.I.P.:

The countless acoustic parameters shown in the various types reports
include the interesting exclusive display (in every position) of the
planes crossed by array elements’ aiming axes and sound pressure
level with 1/3 octave bargraphs (in short, the spl status shown in
1/3 octave bands) which takes into consideration the effect of all
the elements of the array in that point. Click the pic to enlarge.
An accurate prediction of the angle between the elements, even if
they’re a mixture of Hi-Packs and Low-packs, greatly facilitates
“aiming” at the audience. Riggers are thus provided with all the
geometric and mechanical data necessary for carrying out their
work perfectly, without worrying about committing any serious
mistakes. A diagram is created for each array, with all the
parameters for flying according to the limits set by international
safety norms for suspended loads. Click the pic to enlarge.
A sophisticated acoustic and mechanical prediction program greatly
facilitates the installation, setting and aiming of the elements
that make up an OutlineArray. It enables the simultaneous creation,
setting and manual and automatic aiming of 16 OutlineArrays
with two different types of enclosures (Hi-Pack, Low-Pack or
with a
combination of the two, plus sub units).

The software, which has an extremely powerful graphic interface,
enables to predict the effect on up to eight audience areas
simultaneously and the behaviour of 16 different arrays, as well
as offering a large number of functions which make it extremely
versatile. Cross sections and plan views of audience areas can
be viewed simultaneously, designed in a few seconds using the
software’s powerful graphic functions. The array system can be
checked element by element at a glance: inclination, distance
from the target audience area, sound pressure level, simulated
gain adjustment and many other parameters.
