1. SYSTEM DESCRIPTION
The D.A.S. Audio AERO series offers two
units for applications requiring precise control of the
vertical coverageand high sound pressurelevels. The
AERO-38 is an externally powered, three-way, high
efficiency linearray module which integratestwo 12”
low frequency unitswith 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/indoorevents inarenas, stadiums
or theaters. Use of the DSP-3VS digital processor is
recommended for theAERO-38 and the DS
The loudspeakers used in the system
feature advanced technologies; new TAF (
cooling systems,Neodymium magneticcircuits
which allowfor importantweight reductions,titanium
diaphragms for the highfrequency 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.
Tofacilitate transport,the AERO-38units are
equipped with a PL-38 front dolly panel attached by
means ofthe rigginghardware. Thefront dollypanel is
useful when rigging systems. The PL-48S, a metal
dolly for vertically stacking 3 to 4 AERO-38 units is

2. RIGGING SYSTEM
2.1WARNING
Thismanual containsneeded informationfor
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'sresponsibility to staywithin safe limits. Itis
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
subjectto changewithout 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 andload variationthe following ratios must be
met; 5:1 for steel cable slings, 4:1 for steel chain
slings and7:1 polyester slings. Thus, anelement with
a breaking load limit of 1000 kg may be statically
loaded with 200 kg (5:1 safety factor) and
dynamicallyloaded with142 Kg(7:1 safetyfactor).
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 unitsreplaced if indoubt. This is importantto
avoid injuryand absolutely no risksshould 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 personnelthat willcarry outthe inspections.Local
regulations may exist that, in case of accident, may
require you to present evidence of inspection reports
andcorrective actionsafter defectswere found.
Absolutely no risks should be taken with
regards topublic 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 flyenclosures from unsafe structures. Consult
a certified professional if needed. All flying
accessories that are not supplied by D.A.S. Audio are
theuser's responsibility.Use atyour ownrisk.
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 cropresistant 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)must beused.
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
ofthe holewhere thepin getsinserted.

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
attachedto thefirst enclosureof thearray bymeans of
the guides G1A48, G2A48, and six quick release
safetypins.

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 asCD players or turntables, thenthe mixer, then
the processors, and finally the self-powered unit. If
you have several units, it is recommended that you
switchthem onsequentially oneat atime.
Follow theinverse orderwhen switchingoff,
turning self-powered units off before any other
elementin thesound system.
Mute all signal sourcesbefore switching the
uniton oroff.
It is recommended that the red LED
indicators are not lit continuously; at most it should
blinkonly occasionally.
If you wish to have a visual indicationat the
mix position of whether the LIMIT LEDs are lighting,
during equipment set-up, closelyobserve what mixer
VUmeter level corresponds to the level that lights the
enclosure's LIMIT LEDs. That level that should not be
exceededduring theevent.
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 normaluse,
theamplifier panelwill bewarm tothe touch.
If theunit stops playing(or just the mid-high
or the bass sections), the amplifier's overheating
protection may be activated to protect the
componentsfrom thermaldamage.
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
backon automatically.
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. Touse it inthis mode simply plug themixer
intothe enclosure'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 theAERO-38A andthe SUBS. Both sub systems,
AERO-182A andAERO-218A include signal treatment
in the amplifiers extending their frequencyrange 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
external
delay is
recommended.

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,
connectingthem inparallel.
The number of units that can be linked this
way depends on the output impedance of the
equipment drivingthe enclosure, such as the mixeror
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 theenclosure (mixer, console, etc).
For instance, a mixing console with 100 ohm output
impedance allowsdaisy chaining 20boxes, when the
inputimpedance ofthe cabinetsis 20Kohm.

The units do not need extreme EQ. Avoid
high levels of gain on the equalizers. Gain values
above +6 dB on a console's EQ are not
recommended.

As can be seen in the diagram, independent signal lines exist forthe subwoofer units, AERO-182A. The signal that
goesto thesubs isprocessed bymeans ofthe DSP-1Subto adjustthe delaybetween bothsystems.
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-38Aand 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
withadditional elements.
The rain protectors supplied with each unit
havebeen manufacturedwith fireproofmaterials.
The AERO-38A's rain protector features
severalsmall holeson thetopside toallow convection
coolingof theamplifier.

AERO-38 passive systems come with a
metallic backplate, protected bya rain protector,that
features two Speakon NL8 connectors. To a
passive system into an active one, firstly the
screws 11x (3.9x19Pv00)and therain protecto Once
this has been done, the M4x20 screws
thatfix theback plateto thebox.
On the rear side of theback plate the cables
coming from the Speakon connectors lead to a white
male connector, which is inserted in a white female
connector attached to the box. Unplug the male
connector coming from the Speakon connectors and
insertthe maleconnector oftheamplifier inthe female
connectoron thebox.
The fourM4x30 DIN 7985must be screwed
in thefour holes that canbe seen on theradiator area.
The white arrows in the picture above point to the
mentionedholes.
Different rain protectors are needed for the
passiveand theactive versions!!!
The rain protector for the self powered
version is supplied with the amplifier. In order to
attach it to the box just rest the protector on the
receptacleand retightenthe eleven3.9x19PV00 on.
The white connector mentioned above can
be plugged only in one way, so a mistake in the
connections is mechanically impossible. Make sure
that the connection is tight enough, then put the
amplifier in its receptacle paying attention that wires
donot getcaught.
The next step will be to fix the amplifier to
thebox withthe screwssupplied:

To make a passive system into an active
one, firstly the back plate must be removed by
unscrewingthe 12M4x20 DIN965.
After cutting the speakers' wires on the
circuit board, terminals must beattached tothe
speakers' wires as follows: to assure current polarity
attach large 6.3mm female terminal to the
black wire, and a smaller 4.8mm female
terminal to the red wire. Connecting the terminals to
the correct male terminals on the amplifier circuit

NOTE: As AERO-218A and AERO 182A
amplifiers' polarity is inverted referenced to that of
conventional external amplifiers, the polarity of the
speakers' wires must be changed when switching
froma passiveto anactive AeroSeries sub.
