2.2 DESCRIPTION/ACCESORIES
D.A.S. Audio VARIANT 25A and VARIANT
18A units include two rigging structures on each side
of the enclosure. Manufactured from stainless steel
and aluminum, they are affixed with special M8 crop
resistant screws to the wood sides on both models. A
special connecting link is part of each rigging
structure and allows for both stacking or flying with
splay angles ranging from 0º to 10º in 1º increments.
In order to set up the splay angles the quick
release pins supplied with each unit must be used.
4 quick release pins are provided with VARIANT 25A
and 6 quick release pins with the VARIANT 18A.

This manual contains needed information for
flying D.A.S. Audio line array systems, description of
the elements and safety precautions. To perform any
operations related to flying the system, read the
present document 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.
Product improvement by means of research and
development is on going at D.A.S. Specifications are
subject to change without notice.
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.
Absolutely no risks should be taken with
regards to public safety. When flying enclosures from
ceiling support structures, extreme care should be
taken to assure the load bearing capabilities of the
structures so that the installation is absolutely safe.
Do not fly enclosures from unsafe structures. Consult
a certified professional if needed. All flying
accessories that are not supplied by D.A.S. Audio are
the user's responsibility. Use at your own risk.
