RIGGING SYSTEM
Warning
This manual doesn’t contain all needed
information for flying
convert 15A systems. The
present
manual
due
to
the
numerous
combinations possible, only contains a resume of
the elements and the safety precautions.
Please, see the Rigging Manual for more
information.
To perform any operations related to flying the
system, read the Rigging Manual first, and act
on the warnings and advice given. The goal is to
the allow the user to become familiar with the
mechanical elements required to fly the acoustic
system, as well as the safety measures to be
taken during set-up and teardown.
Only experienced installers with adequate
knowledge of the equipment and local safety
regulations should fly speaker boxes.
It is the user's responsibility to ensure that the
systems to be flown (including flying accessories)
comply with state and local regulations.
The working load limits in this manual are the
results of tests by independent laboratories. It is
the user's responsibility to stay within safe limits. It
is the user's responsibility to follow and comply
with safety factors, resistance values, periodical
supervisions and warnings given in this manual.
To this date, there is no international standard
regarding the flying of acoustic systems. However,
it is common practice to apply 5:1 safety factors
for enclosures and static elements.
For slings and elements exposed to material
fatigue due to friction and load variation the
following ratios must be met; 5:1 for steel cable
slings, 4:1 for steel chain slings and 7:1 polyester
slings. Thus, an element with a breaking load limit
of 1000 kg may be statically loaded with 200 kg
(5:1 safety factor) and dynamically loaded with 142
Kg (7:1 safety factor).
When flying a system, the working load must
be lower than the resistance of each individual
flying point in the enclosure, as well as each box.
Hanging hardware should be regularly
inspected and suspect units replaced if in doubt.
This is important to avoid injury and
absolutely no risks should be taken in this
respect.
It is highly recommended that you implement
an inspection and maintenance program on flying
elements, including reports to be filled out by the
personnel that will carry out the inspections.
Local regulations may exist that, in case of
accident, may require you to present evidence of
inspection reports and corrective actions after
defects were found.
It is the user's responsibility to ensure
that the systems to be flown (including flying
accessories) comply with state and local
regulations.
Product improvement by means of research
and development is on going at D.A.S.

Hardware and accessories
The
convert 15A systems of DAS Audio allow
four basic forms for rigging.
Two forms, if you need an horizontal or vertical
mounting and two forms more, if you use the
model ‘-A’ or ‘-RA’.
On 20 page, you can consult the four basic
combinations for the
convert 15A systems.
The
convert 15A enclosure is constructed using
birch plywood and finished with the ISO-flex black
paint providing excellent protection and durability.
The 20º trapezoidal shape of the
convert 15A
enclosure allows for tightly packed arrays with
minimal high frequency interaction.
As an aid when stacking the enclosures in
vertical arrays, rubber locators on the side panels
match with fitting points on the surfaces of
adjacent cabinets preventing slippage.
TM
The optional
InterLox rigging system can be
used to quickly and safely assemble tight-packed
vertical or horizontal curved-source arrays. M-10
threaded rigging points are provided for use in
permanent installation.
Please, see Rigging Manual for more
information.
