3 Launching CAPS
During installation, the Installation Assistant
creates links called CAPS on the desktop of your
computer and in START > PROGRAMS > HK AUDIO
> CAPS. Click these links to start CAPS. After
launching the program, the user interface appears
on your screen with a menu bar and the default
Location panel.
The CAPS interface offers tabs providing access to
the Location, Setup, Rigging and Sub Array panels.
They accept your data and execute the program's
function. In the upper region of the screen, you'll
find a menu bar offering the menus File, Tools,
Options und Help.
3.1 Menu File
• Use the menu option New to create a new
COHEDRA ® sound reinforcement project.
If you have not saved the project you are currently
working on, a dialog appears asking you if you
really want to create a new project. If you confirm,
your current project will be overwritten.
• Use the menu option Open to load a previously
created and stored project. A window opens when
you select this menu option. Select the project's
name (*.lad) and, possibly, its folder in this
window. If you have not saved the project you are
currently working on, a dialog appears asking you
if you really want to create a new project. If you
confirm, your current project will be overwritten.
• Use the menu option Save to store the project you
are currently working on. If you have not named
the project, a window opens prompting you to
enter a name for the project.
• Use the menu option Save As to save the project
you are currently working on under the name
designated here.
• Use the menu option Create Print Version to
create a printable rigging plan in RTF format. A
window opens when you select this menu option.
Enter a name and, possibly, a folder for the new
file that you want to create. Once this is done,
click the Save button to create and view the RTF
file with the rigging plan.
• Use the menu option Exit to quit CAPS. If you
have not saved the project you are currently
working on, a dialog appears asking you if you
really want to exit CAPS. If you quit CAPS without
saving the project, its data will be deleted.
3.2 Tools Menu
Use the menu option Gyro's Little Helper to open
a utility that calculates the inclination of audience
areas. It's rarely feasible to directly measure the
height of the last row in inclining audience areas.
Instead, measure the distance from the reference
point to the beginning of the inclining audience
area (Side 2), the distance from the reference point
to the last row of the inclining audience area (Side 1),
and the length of the inclining audience area (Side 3).
If you enter the values you have measured to the
program, it calculates and indicates the audience
area's inclination. In CAPS, you can then enter this
inclination angle for the given audience area (see
the chapter "Entering Audience Areas" to learn
more about this).
3.3 Options Menu
• Use the menu option Display Font to determine
the typeset employed in CAPS. A window opens
when you select this menu option. Select the
desired settings in it.
• Use the menu option General Options to open a
window that lets you determine basic settings for
the calculations and displays used in CAPS (cf.
figure 7: General Options). The Unit box serves
to determine if lengths are indicated in meters
or feet. Use Warnings and Errors to determine
if CAPS automatically corrects invalid
configurations. The Temperature box lets you
enter the ambient temperature as well as the
unit measurement, Centigrade or Fahrenheit.
CAPS uses the indicated temperature to compute
the velocity of sound and thus the delay times
of signals rendered by the COHEDRA
® system.
The SPL box lets you select the spatial resolution
employed for sound level calculations; in other
words, the distance between two neighboring
points in front of the COHEDRA
® array at which
the sound level is calculated. Though a coarse
resolution requires less computing time than a
fine resolution, it may yield less accurate views,
depending on the frequency. You can enter the
resolution directly in meters or click the Lambda/8
button to select a frequency-dependent resolution
that serves to accurately compute different sound
waves' overlap. Furthermore, you can choose the
Pixel option to define your screen resolution as
the resolution used for calculations. The Grid Size
box lets you determine the size of the grid used to
represent the room, rigging and audience area for
sound level calculations. Click the Default button
to select defaults for all boxes. Click Apply to
confirm the settings; click Ok to close the General
Options window. Click Cancel to close the General
Options window without confirming your settings.
