Beam Angle aims the vertical beam up or
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.
Note that you can also check Focal Point
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.
will change as the setup parameters change.
Note that at any point 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 resolution
choice by pressing one of the bars.
You also have the opportunity to choose the simulations Band-
width, its Center Frequency 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.
-
adds a 1/3 octave selection to the drop down Bandwidth menu
simulation. 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.
