COHEDRA
®
Setups with CAPS
1.3 The Purpose of CAPS
In contrast to EASE 4.0 DLL, CAPS is employed for
mobile sound reinforcement applications that allow
little time for a complex simulation. It calculates
a COHEDRA
® configuration's sound dispersion
across audience areas, whereby the room's
acoustical influences are not taken into account.
CAPS lets you determine the best configuration and
alignment for a sound reinforcement application in
a virtual simulation; that is, without having to map
the room's complexities and without setting up,
testing and adjusting the system until you find the
optimum solution. To this end, CAPS offers tools
that:
• Calculate and view broadband direct sound
dispersion at normal and peak levels in up to
three audience areas
• Calculate and view sound dispersion in
bandwidths ranging from a third of an octave
to three octaves in steps of thirds in up to three
audience areas
• Fine-tune the COHEDRA ® configuration using
predetermined sound dispersion specifications
• Calculate the A-weighted direct sound pressure
level at the FOH location
• Prepare rigging plans
• Calculate the delay between COHEDRA
® line
arrays and ground-stacked subwoofers and
subwoofer arrays
Note!
Bear in mind that precisely measuring a room's
geometrical specs (particularly the audience
areas) and carefully planning the COHEDRA
®
configuration using CAPS will always take less time
than determining the best possible configuration
by trial and error. Oftentimes, DXF data – or at
least scale diagrams of halls – are available on
venues' websites. These sources can provide all the
information required for a simulation.
2 Installing and
Launching CAPS
2.1 System Requirements
A Windows computer with 600 MHz or higher
processor, 128 MB RAM, Win 98, Win NT, Win
2000, or Win XP OS
2.2 Installation
Place the CD-ROM containing CAPS into your
computer's disk drive. View the CD-ROM's
contents, for example, via the Windows Desktop
or Windows Explorer. To begin installing CAPS,
double-click the CAPS_Setup.exe icon using the left
mouse button. An Installation Assistant appears; it
will help you install CAPS properly. First indicate the
folder to which you want to load CAPS.
The Installation Assistant offers to create the folder
C:\Programs\HK AUDIO\CAPS for this purpose.
If you agree, click the Next button. If you want to
install CAPS to another folder, click the Browse
button, select the desired folder, and then click
the Next button.
The CAPS Installation Assistant installs and copies
the requisite files to the selected folder. It will let
you know when the installation process has been
completed. Click the Finish button to quit the
Installation Assistant.
2.3 Software Files
CAPS comprises files named CAPS.exe, cdr208.xhn,
RCG32.dll, Mscomctl.ocx and Tabctl32.ocx. CAPS.
exe is the application file. CAPS is launched by
double-clicking the relevant icon. The cdr208.xhn
file contains COHEDRA
® speaker data; this informa-
tion is required to calculate levels and directivity.
RCG32.dll, Mscomctl.ocx and Tabctl32.ocx are
program libraries, or they contain ActiveX control
features required by the application.
Caution:
Never edit the content of or remove files because
CAPS will no longer run if you do.
