Selecting Normalize Beam EQ instructs Beam Steering to apply a normalized EQ curve

to the FIR lters and reduces the amount of EQ that will be needed during nal 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 conguration for its calculations, so be sure you have properly dened

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 specic 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.
