4. RIGGING THE SYSTEM
RCF has developed a complete procedure to set up and hang a line array system starting from software data, enclosures, rigging, accessories,
cables, until the final installation�
WARNING! CAUTION! GENERAL RIGGING WARNINGS AND SAFETY PRECAUTIONS:
- Suspending loads should be done with extreme caution
- When deploying a system always wear protective helmets and footwear
- Never allow people to pass under the system during the installation process
- Never leave the system unattended during the installation process
- Never install the system over areas of public access
- Never attach other loads to the array system
- Never climb the system during or after the installation
- Never expose the system to extra loads created from the wind or snow
WARNING! CAUTION!
The system must be rigged in accordance with the laws and regulations of the Country where the system is used�
It is responsibility of the owner or rigger to make sure the system is properly rigged in accordance with Country and local
laws and regulations�
Always check that all the parts of the rigging system that are not provided from RCF are:
- Appropriate for the application
- Approved, certified and marked
- Properly rated
- In perfect condition
- Each cabinet support the full load of the part of the system below� It is very important that each single cabinet of the
system is properly checked

4. RIGGING THE SYSTEM
RCF SHAPE DESIGNER SOFTWARE AND SAFETY FACTOR
The suspension system is designed to have a proper safety factor (configuration dependent)� Using the “RCF Easy Shape Designer”
software it is very easy to understand safety factors and limits for each specific configuration� To better comprehend in which safety
range the mechanics are working a simple introduction is needed: HL 6 arrays’ mechanics are built with certified UNI EN 10025 Steel�
RCF prediction software calculates forces on every single stressed part of the assembly and shows the minimum safety factor for every
link� Structural steel has a stress-strain (or equivalent Force-Deformation) curve as in the following:
The curve is characterized by two critical points: the Break Point and the Yield
Point� The tensile ultimate stress is simply the maximum stress attained� Ultimate
tensile stress is commonly used as a criterion of the strength of the material for
structural design, but it should be recognized that other strength properties may often
be more important� One of these is certainly the Yield Strength� Stress-strain diagram
of structural steel exhibit a sharp break at a stress below the ultimate strength�At this
critical stress, the material elongates considerably with no apparent change in stress�
The stress at which this occurs is referred to as the Yield Point� Permanent deformation
may be detrimental, and the industry adopted 0�2% plastic strain as an arbitrary limit
that is considered acceptable by all regulatory agencies� For tension and compression,
the corresponding stress at this offset strain is defined as the yield�
In our prediction software the Safety Factors are calculated considering the Maximum Stress Limit equal to the Yield Strength,
according with many international standards and rules�
The resulting Safety Factor is the minimum of all the calculated safety factors, for each link or pin�
This is where you are working with a SF=7
Depending on local safety regulations and on the situation, the required safety
factor can vary� It is responsibility of the owner or rigger to make sure that
the system is properly rigged in accordance with Country and local laws and
regulations�
The “RCF Shape Designer” software gives detailed information of the safety factor
for each specific configuration�
The results are classified in four classes:
GREEN SAFETY FACTOR > 7 SUGGESTED
YELLOW 4 > SAFETY FACTOR > 7
ORANGE 1�5 > SAFETY FACTOR > 4
RED SAFETY FACTOR > 1�5 NEVER ADMITTED

EN
4. RIGGING THE SYSTEM
WARNING! CAUTION!
The safety factor is the result of the forces acting on fly bar’s and system’s front and rear links and pins and depends on many
variables:
- number of cabinets
- fly bar angles
- angles from cabinets to cabinets�
If one of the cited variables changes, the safety factor MUST BE recalculated using the software before rigging the system�
In case the fly bar is picked up from 2 motors, make sure the fly bar angle is correct� An angle different from the angle used in
the prediction software can be potentially dangerous�
Never allow persons to stay or pass under the system during the installation process�
When the fly bar is particularly tilted or the array is very curved, the centre of gravity can move out from the rear links� In
this case the front links are in compression and the rear links are supporting the total weight of the system plus the front
compression� Always check very carefully with the “RCF Easy Shape Designer” software all this kind of situations (even with
a small number of cabinets)�
PREDICTION SOFTWARE – SHAPE DESIGNER
RCF Easy Shape Designer is a temporary software, useful for the setup of the array, for mechanics and for proper preset suggestions�
The optimal setting of a loudspeaker array cannot ignore the basics of acoustics and the awareness that many factors contribute to a
sonic result that matches expectations� RCF provides the user with simple instruments that help the setting of the system in an easy
and reliable way�
This software will soon be replaced by a more complete software for multiple arrays and complex venue simulation with maps and
graphs of the results� RCF recommends this software to be used for each type of line array configuration�
SOFTWARE INSTALLATION
The software was developed with Matlab 2015b and requires Matlab programming libraries�At the very first installation user
should refer to the installation package, available from the RCF website, containing the Matlab Runtime (ver� 9) or the installation
package that will download the Runtime from the web� Once the libraries are correctly installed, for all the following version of the
software the user can directly download the application without the Runtime� Two versions, 32-bit and 64-bit, are available for the
download�
IMPORTANT: Matlab no longer supports Windows XP and hence RCF EASY Shape Designer (32 bit) doesn’t
work with this OS version�
System particularly tilted System very curved

EN
4. RIGGING THE SYSTEM
You may wait a few seconds after the double click on the installer because the software checks if Matlab Libraries are available�
After this step the installation begins� Double-click the last installer (check for the last release in the download section of our
website) and follow the next steps�

EN
After the choice of folders for the Shape Designer software (Figure 2) and Matlab Libraries Runtime the installer takes a couple of
minutes for the installation procedure�

DESIGNING THE SYSTEM
The RCF Easy Shape Designer software is divided into two macro sections: the left part of the interface is dedicated to project
variables and data (size of audiences to cover, height, number of modules, etc�), the right part shows the processing results�
At first the user should introduce the audience data choosing the proper pop-up menu depending on the size of the audience and
introducing the geometrical data� It is also possible to define the height of the listener�
The second step is the array definition selecting the number of cabinets in the array, the hanging height, the number of hanging
points and the kind of available flybars� When selecting two hanging points consider those points positioned at the flybar extremes�
The height of the array should be considered referred to the bottom side of the flybar, as shown in the picture below�
After entering all the data input in the left part of the user interface, by pressing the AUTOSPLAY button the software will perform:
- Hanging point for the shackle with A or B position indicated if a single pickup point is selected, rear and front load if two
pickup points are selected�
- Flybar tilt angle and cabinet splays (angles that we have to set to each cabinet before lifting operations)�
- Inclination that each cabinet will take (in case of one pick up point) or will have to take if we were to tilt the cluster with the
use of two engines� (two pick up points)�
- Total load and Safety Factor calculation: if the selected setup doesn’t give Safety Factor > 1�5 the text message shows in red
color the failure to meet the minimum conditions of mechanical safety�
The autosplay algorithm was developed for optimum coverage of the audience size� The use of this function is recommended for
the optimization of the array aiming�A recursive algorithm chooses for every cabinet the best angle available in the mechanics�

RECOMMENDED WORKFLOW
Pending the official and definitive simulation software, RCF recommends the use of HL 6 Shape Designer together with
Ease Focus 3� Because of the need of interaction between different software, the recommended workflow assumes the
following steps for every array in the final project:
- Shape Designer: audience and array setup� Calculation in “autosplay” mode of flybar tilt, cabinet and splays�
- Focus 3: reports here the angles, tilt of flybar and presets generated by Shape Designer�
- Shape Designer: manual modify of splay angles if the simulation in Focus 3 does not give satisfactory results in order to
check the safety factor�
- Focus 3: reports here the new angles and tilt of flybar generated by Shape Designer� Repeat the procedure until good
results are achieved�
