Selecting Normalize Beam EQ instructs Beam Steering to apply a normalized EQ curve
to the FIR filters and reduces the amount of EQ that will be needed during final commis-
sioning. Some users, however, prefer to do all the EQ themselves so this feature can be
turned off. See Preferences on page 32). This feature relies upon the accuracy of the
audience area configuration for its calculations, so be sure you have properly defined
the audience area and the location of the array before using it.
Auto-Focus in RHAON 1.10.2 will analyze your project and suggest the number of
beams, their acoustic center location, their aiming and relative gain - all at the touch of
the Auto-Focus button. We’ll explore its use later on.
Note that at any point in the setup process you can click on the Calculate Mapping bar
to tell the program to map the array’s performance on the audience area.
As soon as you press Calculate Mapping, a pop up screen will ask you to choose the
resolution of the simulation. Low Resolution simulations are much faster to run than
High Resolution ones. All you need to do to start the simulation is to make your resolu-
tion choice by pressing one of the bars.
You also have the opportunity to choose the simulations Bandwidth, its Center Frequen-
cy and its Weighting. The Frequency section lets you select center frequencies from
100 to 10,000 Hz. The default selections for the Bandwidth section allows you to run the
simulation over 1 octave or 3 octave bands or Broadband.
You can change this by going to the Options window (F9), selecting the Appearance tab
and checking Show 1/3rd Octave. This adds a 1/3 octave selection to the drop down
Bandwidth menu and the opportunity to set a specific bandwidth for the mapping simula-
tion. In the graphic shown, for example, selecting “to 3150 Hz” would run the simulation
over the frequency range of 1000 too 3150 Hz.
We’ll choose the default settings for this exercise, but you may want to try out all the
different settings to become familiar with them and the performance of steerable arrays.
Beam Angle aims the vertical beam up or down. Try it out by selecting Beam Angle [*],
changing the number and observing its effect.
Note that after entering a new number you will
need to press Enter to initiate the change. You
will also need to do a new Calculate Mapping
to view the change. The old map will have
been wiped out by the program as you made
the change.
You can also check Focal Point [ft] and then
enter the exact location of the beam’s focal
point in Height from Floor and Distance from
Front.
Another way to position the beam’s focal point
is to use the mouse cursor to grab the end
point of the aiming axis and move it to the
desired location.
Try it out. It’s easy to do. The SPL levels in
the graphs will change as the setup param-
eters change.
