1. SYSTEM DESCRIPTION
The D.A.S. Audio AERO series offers two
units for applications requiring precise control of the
vertical coverage and high sound pressure levels. The
AERO-38 is an externally powered, three-way, high
efficiency line array module which integrates two 12”
low frequency units with 4” voice coils, two 10” mid-
range devices which utilize 3” voice coils and one
compression driver with 4” coil and 1.5” exit
geometry in a single unit. The compression driver is
coupled to the Serpis-38 high frequency plane wave
adaptor insuring coherent high frequency summing
and the generation of a flat, isophasic wave front.
When increased sound pressure level in the low
frequency range is required, the system can be used
in conjunction with the AERO-218Sub
subwoofer units. There are self powered version of
eachcabinet,AERO-38A,AERO-218A,AERO-182A.
The system is ideal for applications such as
large-scale outdoor/indoor events in arenas, stadiums
or theaters. Use of the DSP-3VS digital processor is
recommended for the AERO-38 and the DS
The loudspeakers used in the system
feature advanced technologies; new TAF (
cooling systems, Neodymium magnetic circuits
which allow for important weight reductions, titanium
diaphragms for the high frequency sections, and low-
mid frequency cones manufactured using crossed
fibers and elastic suspension that provide exceptional

Both units are manufactured using 15/18
mm Finnish Birch plywood. The AERO-38 enclosure
shape is trapezoidal with 5º angles. The AERO-
218 enclosures are rectangular.
The Aero-38 and AERO-182 systems incorporate
captive rigging hardware which is compatible with
one another and designed to provide a fast, simple
and safe rigging by means of quick release safety
pins. Splay angles can be changed from 0º to 3.2º in
0.8º increments and from 3.2º to 9.6º in 1.6º
increments.
To facilitate transport, the AERO-38 units are
equipped with a PL-38 front dolly panel attached by
means of the rigging hardware. The front dolly panel is
useful when rigging systems. The PL-48S, a metal
dolly for vertically stacking 3 to 4 AERO-38 units is
available as an accessory. The AERO-218 units
can be moved by way of the four rear located casters.

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
oftheholewherethepingetsinserted.

loads. It features a center reinforcement bar that is
also used for the lifting slings. The force of both the
rear and the front chain hoist will determine the tilt
angle of the whole array. The structure will be
attachedtothefirstenclosure of the array by means of
the guides G1A48, G2A48, and six quick release

A sound system should be switched on
sequentially. Switch on the self-powered unit last in
your sound system. Switch on the sound sources
such as CD players or turntables, then the mixer, then
the processors, and finally the self-powered unit. If
you have several units, it is recommended that you
switchthemonsequentiallyoneatatime.
Follow the inverse order when switching off,
turning self-powered units off before any other
elementinthesoundsystem.
Mute all signal sources before switching the
unitonoroff.
It is recommended that the red LED
indicators are not lit continuously; at most it should
blinkonlyoccasionally.
If you wish to have a visual indication at the
mix position of whether the LIMIT LEDs are lighting,
during equipment set-up, closely observe what mixer
VUmeter level corresponds to the level that lights the
enclosure's LIMIT LEDs. That level that should not be
exceededduringtheevent.
LIMIT
Due to their high efficiency, the Aero Series
amplifiers generate very little residual heat and
therefore do not need a fan for cooling. In normal use,
theamplifierpanelwillbewarmtothetouch.
If the unit stops playing (or just the mid-high
or the bass sections), the amplifier's overheating
protection may be activated to protect the
componentsfromthermaldamage.
Overheating may be due to insufficient
cooling, or to very aggressive use in extremely hot
conditions. Do not use the unit in proximity to high
powerlights.
Once the amplifier cools down, it switches
back on automatically. If the unit should shut down
again, try reducing the volume a notch to avoid
overheating.

3.8 OVERHEATING
3.10 LOW MAINS VOLTAGE
If mains voltage falls below the shutdown
voltage for the unit, it will stop playing. When
acceptable levels are regained, the unit will switch
backonautomatically.
3.9 ECUALIZATION
The AERO-38A can be used full-range. Full-
range use is only recommended for applications
where low SPL level and no bass reinforcement is
adequate. To use it in this mode simply plug the mixer
intotheenclosure'sinput.
The most common use will be combined
with the AERO-218A (AERO-182A). In this case
different outputs of the mixing console will be used
with the AERO-38A and the SUBS. Both sub systems,
AERO-182A and AERO-218A include signal treatment
in the amplifiers extending their frequency range up to
85Hz. As well, the amplifier of the AERO-38A
incorporates signal treatment which provides
frequency range extension down to 60Hz. Due to this
overlap between 60-85Hz the use of an
to control and adjust the phase of the subs

The connector is an output XLR
in parallel with the input connector and is useful for
daisy chaining the input signal to a number of boxes,
connectingtheminparallel.
The number of units that can be linked this
way depends on the output impedance of the
equipment driving the enclosure, such as the mixer or
processor. Typically, to avoid signal degradation, the
maximum number that can be daisy chained is given
by the formula Zc>10Zs, where Zc is the load
impedance and Zs is the output impedance of the
equipment driving the enclosure (mixer, console, etc).
For instance, a mixing console with 100 ohm output
impedance allows daisy chaining 20 boxes, when the
inputimpedanceofthecabinetsis20Kohm.

3.12 RAIN PROTECTOR
Electronic devices can be damaged when
exposed to water or moisture. AERO-38A and AERO-
182A/218A amplifiers must be protected when
installed outdoors. A rain protector is supplied with
eachAERO-38A and AERO-182A/218Aunit.
The rain protector is specially designed to
withstand soft rain and other meteorological
conditions for short periods of time. In the case of
heavy rains, storms or permanent outdoors
installations the sound system must be protected
withadditionalelements.
The rain protectors supplied with each unit
havebeenmanufacturedwithfireproofmaterials.
The AERO-38A's rain protector features

4. ASSEMBLING AN ARRAY
4.1TRANSPORTING THE CABINETS
AERO-38 units can be transported by using
the front panel dolly PL-38 or by using the PL-48S steel
dolly which can transport a maximum of 4 AERO-38
stacked.
The AERO-218Sub can be transported on
the rear located casters. Their rectangular shape
facilitates ground stacking without the use of the
rigging hardware. The AERO-182 cabinets can be
transportedbyusingthefrontpaneldollyPL-48.
4.2 PLANNING/INSPECTION
4.3 ASSEMBLING AN ARRAY “ONE
BY ONE”
When few units are to be used (minimum
systems recommended is 6 units) or when the dolly
platforms cannot be used due to a lack of space, the
enclosures will have to be hung “one by one”. The first
step will be to attach the AX-AERO48 or the AX-
AERO38 grid structure to the hoists. The chain slings
need to be attached to the structure using the
shackles provided with the grid. Once this has been
accomplished, the grid structure can be placed in a
vertical position by lifting the rear hoist and lowering
the front hoist so that the rear of the grid is on top and
the front of the grid at the bottom, ready to receive the
first box rolled into place by means of the PL-38 dolly
platform.
The next step is to attach the first unit to the
grid by introducing the G1A48 and G2A48 guides in
the receiving points of the grid structure and assuring
them with the six safety pins. The safety pins should
be inserted in the slot of the G2A48. It is very
important to make sure that the pins have been
insertedandlockedcorrectly.
Once the first unit of the array has been
attached to the AX-AERO48 or AX-AERO38, the
assembly should be lifted by way of the rear hoist until
the wheels of the PL-38 dolly platform lift off the
ground. From this point on, the front hoist can be used
tolifttheboxintoahorizontalposition.
Before installing the AERO systems it is a
good idea to run a simulation using the AEROWARE
program utilizing the venue dimensions. This way we
can determine the needs that should be met by the
rigging structures such as hoists, cranes, beams,
rigging points, etc. Besides providing weight
information, the program also provides users with
splay angle information, safety pin positions and
coveragepredictions.
Inspection is the next step after planning
and acquiring all the necessary parts needed to
elevate the systems. All parts, including the hardware
attached to the enclosure, the safety pins, etc. should
be thoroughly inspected before each use. Units
exhibiting deformations, cracks or any other defect
shouldbereplacedwithnewunits.
It is extremely important to assure that each
and every one of the aforementioned structures is
capable of supporting a superior load than that of the
completesystem.
It is important to establish an inspection
routine for the complete rigging system before each
event or installation as well as establishing the
maximumloadspecificationsofthehoiststobeused.
Rigging should be carried out by experts
familiar with the way the systems function and their
characteristics.
On occasions, it may be convenient to have
additional tie down points to impede the array from
twistingorswinging.

Once the boxes have been joined, the front
dolly panels can be removed. The next boxes should
be attached “one by one” using the methods
described. Finally, the array should be hoisted to the
correct height and secured with slings to avoid
swinging. This method is more time consuming than
assembling an array by the “all at once” procedure,
but is appropriate for situations due to a lack of space
in which to array the system. During the process, the
safety pins should be checked making sure they are
secured correctly. Once the complete array has been
lifted into place, additional slings should be attached
tosecurethearrayandavoidswinging.

4.4 ASSEMBLING AN ARRAY USING
THE PL-38 PLATFORM
The PL-38 platform can be used to easily
transport AERO-38 units to the assembling area. To
use this method of assembling and hoisting the array,
there must be enough space to permit linking all the
boxesfromthefrontofthetherigginghardware.
The first step will be to attach the AX-
AERO48 or AX-AERO38 grid and the 2 hoists. Once
this has been accomplished, the grid structure can be
placed in a vertical position by lifting the rear hoist and
lowering the front hoist so that the rear of the grid is on
top and the front of the grid at the bottom, ready to
receivethefirstbox.
Rigging points
The next step is to attach the first unit to the
grid by introducing the G1A48 and G2A48 guides in
the receiving points of the grid structure and assuring
them with the (6) safety pins. The safety pins should
be inserted in the slot of the G2A48. It is very
important to make sure that the pins have been
insertedandlockedcorrectly.

Lift the box and introduce the
G1A48 guides securing them
with the safety pins.

Once the first box is attached to the
structure, the remaining boxes should be brought to
the array and attached repeating the previous steps (1
and 2) using G1A48 guides and safety pins per side
making sure that the pins have been inserted and
lockedcorrectly.
Proceed to attach the remaining units in the
same manner until all the array units are attached to
one another. For example, if we are assembling a six
unit array, the process will be repeated six times.
When all the units are attached, the complete array is
readytobehoisted.
When the rear of the enclosures come
together, the G2A48 rear guides should be positioned
(4) into the hardware of the box above, inserting (5)
the safety pins in the correct angle position. Since the
boxesareflown,thesafety pins should be in the slot of
theG2A48guide.
