3. RIGGING
3.1 Warning
The AX-TRUSS rigging hardware has been
designed to fly the cabinets from structure trusses of
50mm diameter (2 in diameter). The AX-TRUSS base
must be fixed to the upper rear corner of the box by
means of two M10 screws. The screw needed to
attach the AX-TRUSS base to the upper side of the box
is the same that comes with the box on that position.
The screw to be inserted on the rear side of the box is
a special one that is provided with the AX-TRUSS
accessory.
AX-TRUSS allows for several vertical angles
from +10º to -35º. The vertical angle is set up by
inserting a highly resistant quick release pin into the
holes in the AX-TRUSS base.
3.3 Rigging with AX-TRUSS
SML are the models in the Stage Monitor
Series that feature the necessary hardware to be
flown. As has been said above, SML are versatile
multipurpose cabinets which can also be used as a
low profile floor monitor.
SML cabinets feature 6 “L” shaped internal
metal hardware pieces, each one including 2 M10
nuts, thus providing a total of 12 rigging points.

This manual contains needed information for
flying DAS Audio Stage Monitor 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 ongoing 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.
