2. RIGGING SYSTEM

2.1WARNING

Thismanualcontainsneededinformationfor

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

localregulations.

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

subjecttochangewithoutnotice.

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

dynamicallyloadedwith142Kg(7:1safetyfactor).

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

andcorrectiveactionsafterdefectswerefound.

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

theuser'sresponsibility.Useatyourownrisk.

D.A.S. Audio AERO-38 and AERO-182 line

array systems, include 2 rigging structures on each

side of the box. Manufactured from zinc plated steel

they are painted black and are affixed to an internal

plate with special crop resistant screws. Two special

stainless steel guides are assembled to each of the

structures: G1A48 (front guide) and G2A48 (back

guide), allow for stacking or flying of boxes.

To lock both guides, six (6) quick release safety pins

(supplied)mustbeused.

The G1A48 front guide provides a solid

connection to the box and whatever is on top of it,

while the G2A48 rear guide determines the vertical

splay angle (whether stacked or flown), as a function

To aid the setting of the G2A48 guide in the

corresponding hole in the top box, each hole is labeled

with an associated angle, both for stacked and flown

applications. To fit the guides into the holes, highly

resistant 8 mm quick release pins with a ball safety

lock areused.
