Setups with CAPS
4 Creating a New Project
To create a new project, first launch CAPS or, if
CAPS is running, select the menu option New
from the File menu.
4.1 Entering Project Data
When creating new projects, make a habit of
entering project data first to ensure the project is
easily identified later. To enter project data after
launching CAPS, open the Location panel, if it is
not already on your screen. Type a meaningful name
into the Project box, your name into the Author
box, and brief remarks that will help you identify the
project later into the Comments box. For example, if
you want to simulate different variants of the same
sound reinforcement project in CAPS, type in a
comment describing the individual variant's
unique features.
4.2 Entering Room Data
Under Room, type the given room's width into
the Width box, and its height into the Height box.
This information is used solely to represent the
room's dimensions in the side view provided in the
Location and Setup panels; it has no influence on
acoustical calculations. For outdoor sound reinforce-
ment applications, enter the depth of the event
grounds to the Width box and a height greater than
the projected height of the flown COHEDRA
® array
(possibly the height of the tiers).
Under Reference Point indicate in the X and Y
boxes the respective X and Y coordinates of a
reference point. You must later measure from this
reference point individual audience areas' distances
and dimensions, as well as the position of the
COHEDRA
® array. As a rule, the reference point is
located at the left bottom corner.
In the X and Y boxes under FOH, indicate the X and
Y coordinates of the FOH location. You will later
see indicated here the calculated A-weighted sound
pressure levels achieved by the givenconfiguration
at the FOH location.
4.3 Entering Audience Areas
Click the Audience Areas box to open a list from
which you can select the number of audience areas
(up to 3). Then enter the coordinates for each
audience area. You have several mapping options.
The first is to type for the given audience area the
first row's X and Y coordinates into the X1 and Y1
boxes, and the last row's X and Y coordinates into
the X2 and Y2 boxes. This option is a good choice
when coordinates are derived from diagrams rather
than being measured on site.
If you are compelled to map distances and
dimensions on site, measuring the height of the last
row of inclining audience areas is rarely a workable
option. In this case, measure the distance from
the reference point to the first row of the given
audience area, and enter these X and Y coordinates
into the X1 and Y1 boxes for this audience area.
Select the menu option Gyro's Little Helper from
the Tool menu and also enter the X1 value into the
Side 2 box. Measure the distance from the reference
point to the last row of the audience area and enter
this value into the Side 1 box. Now all you have to
do is measure the length of the audience area from
the first to the last row and enter this value into the
Side 3 box. Then you will see indicated in the Angles
box the audience area's inclination. Enter this value
into the given audience area's Angles box on the
Location panel. Type the length of the audience area
(the value you entered into the Side 3 box in Gyro's
Little Helper) into the Length box for the given
audience area. This completes the procedure for
mapping an inclining audience area.
Note!
Measure all X and Y coordinates used to map
audience areas from the reference point indicated
in the Reference Point box.
