Ease; Flown Or Stacked Arrays - PROEL AXIOM - VERSION 2.0 Manual

configuration, the load on each motor is automatically recalculated. The LAC software does not take into
account the power cable weight, and the position of the array, once mounted, could be different from the

simulated one .
From the Mechanical view window, if you click on the left box, you can switch immediately to the
Vertical View window, and the different pointer symbol indicates you've switched area.
Obviously, when you switch from automatic to manual configuration you determine the movement of
the array and the sound pressure map will have to be recalculated in relation to the new inclination of
the system. The software allows you to save all settings for the array configuration and for the location.
For further details about the software, please refer to the software operating manual.

4.2.2 EASE

The functions featured by the LAC simulation software are what you need for every typical live ap-
plication; when you deal with indoor installations, such as in theatres or sports arenas, knowledge
of total sound range distribution, that is direct range plus reflected range distribution, can be useful.
Several software systems allowing the simulation of acoustic sources and their interaction with a three-
dimensional location are available on the market. The package usually chosen by professionals is
the EASE (Enhanced Acoustical Simulator for Engineers) by ADA Acoustic Design Ahnert; all Proel
speakers feature models for EASE 4.1

4.3 Flown or stacked arrays

All AXIOM systems can be either flown or ground stacked. Descriptions of all mounting procedures are
in chapter 5.
The best mounting option – suspended or stacked – is related to the kind of sound reinforcement you
need to create and to any mounting constraints you might face. In most common applications, a flown
array is the best choice, as it allows a more uniform coverage of the audience area. We could say that
any time the audience area lies at a uniform level below an available hoisting point and stretches out for
a certain length, then a flown array is the best choice, as it allows a better sound pressure distribution
over the whole area.
Figure 4.3: Comparison of 6 AX3210P composing: (a) a flown array, (b) a stacked array (not advised).
In case of typical outdoor events, we do not advise stacking the equipment on stage. Figure 4.3
shows a comparison of the SPL level map for both situations: the configuration with a flown array has
a more uniform distribution, whereas the stacked configuration creates a very narrow central emission
lobe which is not very well suited to the audience area.
Nonetheless, there are complex situations in which stacking the equipment is the best solution, e.g.
in theatres or arenas where the audience area is vertically dispersed. There are also situations in which
suspension is just not possible: in those cases the system must be stacked and its setup needs to be as
thorough as possible in order to achieve the most uniform coverage possible.

We verified experimentally that if you move one hole down toward the front part of the bar for coupling points (that is -1 in the
numeration of the holes of KPTAX3210 flying bar) in most situations you will be able to compensate the cable weight.
