1. SYSTEM DESCRIPTION

The D.A.S. Audio AERO series offers two
units for applications requiring precise control of the
vertical coverage andhigh sound pressure levels.The
AERO-48 is an externally powered, three-way, high
efficiency line arraymodule which integrates two 15”
low frequency units with 4” voice coils, four 8” mid­range devices which utilize 2.5” voice coils and two
compression drivers with 3” coils and 1.5” exit
geometry ina singleunit. Thecompression drivers are
coupled to two Serpis high frequency plane wave
adaptors 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
inconjunction withthe AERO-218 subwooferunit.

SUB

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 the AERO-48 and the DS

the subwoofer system. Not usingthe

P-1Sub

for

DSP-3VSdigital
processor with the AERO-48 will adversely affect the
soundquality andmay damagesystem components.

The model AERO-48 includestwo 15GN 15”
cone transducer with 4” EFW voice coils and
Neodymium magnet assemblies in a bass-reflex
configuration.Four 8MN, 8”speakersarranged ona V
shape, incorporating 2.5” EFW voice coils,
Neodymium magnet assemblies and TAF cooling
system are used for mid-range reproduction. High
frequencies are handled by two M-10N high
frequency compression drivers with 3” EFW coil,
Neodymium magnet and 1.5” exit coupled to twin
SERPIS plane wave guide. The SERPIS plane wave
adaptor alsoserves asa heatsink for thecompression

2. RIGGING SYSTEM

2.1WARNING

Thismanual containsneeded informationfor
flying DAS 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 responsibilityto 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
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 variation the followingratios must be
met; 5:1 for steel cable slings, 4:1 for steel chain
slings and 7:1polyester 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 units replacedif in doubt. This isimportant to
avoid injury andabsolutely no risks shouldbe taken in
this respect. It is highly recommended that you
implement an inspection and maintenance program
on flyingelements, including reportsto be filledout by
the personnelthat willcarry out theinspections. 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 to publicsafety. Whenflying 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 DAS Audio are
theuser's responsibility.Use atyour ownrisk.

2.2 DESCRIPTION/ACCESSORIES

DAS Audio AERO-48 line array systems,
include 2 rigging structures on each side of the box.
Manufactured from zincplated steel they are painted
black and are affixed to aninternal 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.

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 lock both guides,
six (6) quick release safety pins (supplied) must be
used.

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.

G2A48

QUICK RELEASE PIN 8X30
(6 UNITS PER CABINET)

G1A48

To aid the setting of the G2A48 guide in the
corresponding holein the topbox, eachhole 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.

The AX-AERO48 grid is made from 100 x50
x 6mm steel tubing and is designed to handle great
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

breaking load limit and the
maximum safe working load limit (SWLL). In this
case, the breaking load limit of each of the flying
points is 4,000 kg (8,820 lbs) as determined by
destructive testing in independent laboratories. With
a 10:1 safetyfactor, atotal amount of 1,600kg (3,527
lbs) can be flown from the 4 flying points. Each flying
point has a capacity of 400 kg (882 lbs) with a 10:1
safetyfactor.

4 x 400Kg (10:1)

T

he maximum number of units that can be

Theuseoftwohoistswitha loadcapacity as
expressed on the previous page is mandatory. It
should be kept in mind that at certain moments, the

3. ASSEMBLING AN ARRAY

3.1TRANSPORTING THE CABINETS

AERO-48 units can be transported by using
the frontpanel dollyPL-48 orby usingthe PL-48Ssteel
dolly which can transport a maximum of 3 AERO-48
stackedin anarc or4 unitsstacked vertically.

The Aero-218SUBcan be transportedon the
rear located casters. Their rectangular shape
facilitates stacking without the use of the rigging
hardware.

3.2 PLANNING/INSPECTION

3.3 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 willhave tobe hung “oneby one”.The first
step will to attach the AX-AERO48 grid structure to
the hoists.The chain slings needto be attached tothe
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 toreceive thefirst box.

Before installing the AERO systems it is a
good idea to run a simulation with 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.

It isextremely important toassure that each
and every one of the aforementioned structures is
capable of supporting a superior load than that of the
completesystem.

Inspection is the next step after planning
and acquiring all the necessary parts needed to
elevate thesystems. All parts,including the hardware
attached tothe enclosure,the safetypins, etc. should
be thoroughly inspected before each use. Units
exhibiting deformations, cracks or any other defect
shouldbe replacedwith newunits.

It is important to establish an inspection
routine for the complete rigging system before each
event or installation as well as establishing the
maximumload specificationsof thehoists tobe used.

The next stepis to attach thefirstunit to the
grid by introducing the G1A48 and G2A48 guides in
the receiving points ofthe 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
insertedand lockedcorrectly.

Aero-48 Manual del usuario/ User´s manual 34

The quick release pins(3 and 4) must be
inserted through the slot of G2A48

Once the first unit of the array has been
attached to the AX-AERO48, the assembly should be
lifted by way of the rear hoist until the wheels of the
PL-48dolly platform lift off theground. From thispoint
on, the front hoist can be used to lift the box into a
horizontalposition.

Swing the G2A48 guide
into place and secure it
with the safety pin.

Once the splay angle between the first two
boxes has been determined, the front of the box can
be lifted into place. Three people will be needed to
undertake thisoperation, two tolift the boxand one to
fitthe G1A48guide andsafety pinsinto theupper box.

Once the firstbox has been placed at0º and
raised approximately 75cm (30 in) the second box of
the array can be placed nearby. Once located in
position, the G2A48 guides of the second box should
be freed and inserted in the rear located receiving
points of the suspended box and secured with the
safetypins.

Lift the box and free
the G1A48 guides.

35Aero-48 Manual del usuario/ User´s manual

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

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.

3.4 ASSEMBLING AN ARRAY USING
THE PL-48 PLATFORM

The PL-48 platform can be used to easily
transport AERO-48 units to the assembling area. To
use this method ofassembling and hoisting the array,
there must be enough space to permit linking all the
boxesfrom thefront ofthe therigging hardware.

The first step will be to attach the AX­AERO48 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 hoistso that the rear of thegrid is on top and
the frontof the gridat the bottom,ready to receivethe
firstbox.

Rigging points

The nextstep is to attachthe first unit tothe
grid by introducing the G1A48 and G2A48 guides in
the receiving points ofthe 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
insertedand lockedcorrectly.

AERO-48

This method is more time consuming than
assembling an array by the “all at once” procedure,
but is appropriate forsituations 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
tosecure thearray andavoid swinging.

Aero-48 Manual del usuario/ User´s manual 38

To lower the system, both hoists should be
used until the lowest box is about 1 meter from the
ground. From there on, only the front hoist should be
used so that the array assembly begins to lean
forward, atthe same time, thePL-48 platformsshould
be reattached. When the wheels of the lowest
enclosure are firmly on the ground, the array
assemblycan nowbe loweredusing therear hoist.

While the array assembly descends, the
rear of the enclosures will come together, at that
moment, the safety pins which hold the G2A48
guides in place should be removed. Once removed,
the guides should be swung back into the box they
belong to. Finally, the boxes should be totally
detached from one another by releasing the G1A48
guide.

3.5 ASSEMBLING AN ARRAY
USING THE PLATFORM PL-48S

The PL-48S platform can be used to easily
transport 3/4 units of the AERO-48; in both arc shape
orstacked onthe platform.

The PL-48S platform can be used to
transport boxes forming a vertical arc, ready to be
flownor simplystacked.

Either way, dueto theweight of theboxes, it
isrecommendedthat forthe firsttime, the enclosures
be placed on the platform from a flown position. In
other words, the array should be suspended (either
onebyone orusing thePL-48S)and thenlowered onto
thePL-48S ingroups.

A) Cabinets splayed in arc (MAX. 3 units):

If we want to place six AERO-48 units on 2
PL-48S, the first step would be to suspend them all,
and then lowerthe array assembly onto the platforms

The lowest box is now attached to the
platform. Now the array should be lowered until the
boxes are resting on one another. When the lower
three boxes are in this position, the safety pins
attached to the G2A48 guides joining boxes 3 and 4
should be removed to separate the array into two
groupsof boxes.

can be removed (8) and the PL-48S_2 guides can
return to their stored position (9). It is mandatory to
remove the safety pins between boxes 3-4, but
between 4-5, and 5-6, they can be left in place with
theangle preparedfor thenext event.

The next step is to roll under the remaining
boxes, an empty PL-48S and lower the boxes until

they are within close proximity of the platform. The
procedure should now be repeated, freeing the PL­48S_2 pieces (13) from the platform, turning them
(14) and securing them (15) to the rear rigging
hardwareof thenumber 3box.

The last step consists of lowering the
remaining arrayso thatthe safetypins canbe inserted

It is important to check that pins cannot be
removed by pulling outward and that they have been
inserted in the G2A48 hole instead of the guide slot.
Otherwise the box would not remain in the expected
angle.

The procedure is the same for the next
boxes. The cluster must be lowered again (15) until
the safety pins of box 3 are loose. Remove the pins
(16) so the G2A48 rear guides return to their stored
position (17). Insertthe safety pins into theholes (18)

3.6 ASSEMBLING A CLUSTER

USING THE PL-48S PLATFORM

AERO-48 boxes canbe easily transported in
groups ofthree when stackedon the PL-48Splatform.
This arrangement is also useful and saves time when
setting up a cluster. Let us see what would the
procedurebe whenflying asix boxcluster.

In order to attach the box on top to the grid,
front guides G1A48 and rear guides G2A48 must be
swung (2) and inserted into the AX-AERO48 grid
receiving points. Oncethis has been done, detach the
6 safety pins from their receptacles and secure the
boxto thegrid.

After the AX-AERO48 grid has been

attached to the motors, it should be lifted at about

1.8m (5.5 ft) from the ground. Now the platform
containing the first threestacked AERO-48 boxes can
berolled underthe grid.

are 0.8ºbetweenthe first and secondboxes, and 1.6º
between the second and the third boxes. The cluster
can now be lifted by the two motors, and the PL-48S
platformdetached.

The first step to detach the PL-48Splatform
from the bottom box is to release (6) the safety pins
which secure the PL-48S_1 piece to the platform and
the PL-48S_2 piece to the box. After raising the
cluster a bit, the safety pins which connect the PL­48S_1 piece to the box can be released (8) also. PL­48S_1 piece should now be reattached again to the
platform.

Select the angle between cabinets
introducing (5) the pins in the holes of the rigging
systemthrough theslot ofG2A48.

the guides fit into the rigging hardware of the next
box. Set the angle between both boxes by inserting
thesafety pinsin thecorrect hole.

From here on, the process is similar to the
previously described. Detach the safety pins from
their receptacleson thesides of theboxes, swing(12)
the G2A48 rear guides, place them into the rigging
hardware of the next box and insert (13) the safety

4. SIGNAL PROCESSING

4.2 LIMITER SETTINGS

The use of the DSP-3VS digital processor is
highly recommended when running the AERO-48
sound system, and the use of the DSP-1Sub when
running the AERO-218Sub. Whenever another
loudspeakermanagementsystem isgoing to beused,
it should be configured with the parameters provided
by the manufacturer. Not doing so may damage the
system´s speaker components and affect the sound
quality.

The DSP-3VS digital processor is a three­way crossover with gain controls that offer +/- 6dB
variation per way. The processor has two inputs and
six outputs with level indication and muting for each
of the outputs. The digital processor includes fourth
order filters and parametric equalizers. The user
adjustablelimiters areaccessible fromthe frontpanel.

The DSP-3VS includes 10 presets that can
be selected fromthe front panel. Eachpreset memory
recalls specific operating parameters for a specific
DASspeaker systems.The selectedprogram isvisible
onthe LCDscreen locatedon thefront panel.

4.1 DSP-3VS INSTRUCTIONS

The following formulas can be used to establish the
limiter voltage:

AmplifierData:

V=P *Z
G=

G =20log(V /S)

Limitlevel (v)=V /G

d

Limitlevel (dBu)=20log[limitlevel (v)/0.775]

Where P is the maximum power to be

d

deliveredin watts

To selecta program, turn therotary mini-DIP
switch onthe frontpanel labelled“Presets”. Thename
of the recalled preset will appear on the LCD screen.
The firsttime theDSP-3VSis connected, thenumber 1
program for the AERO-48 system will appear on the
frontpanel screen.

To select the limit levels for each of the
ways, turn the rotary mini-DIP switches on the front
panel labelled “Limiters”. The limit level expressed in
Vrmsand dBuappears onthe frontpanel screen.

The “Settings” button allows the user to
check thesaved limitlevels. The limitlevels appear on
the screen and after 5 seconds, the preset program
returnsto thescreen.

Thelimitlevelstobe enteredshould beequal
to or lower than the sensitivity of the amplifiersused.
Amplifier manuals provide the sensitivity at 8 Ohms
and 4Ohms. Takeinto account the load impedanceat
which the amplifiers will be working when adjusting
thelimit levels.

When usingamplifiers with a greateroutput
power than that recommended by the speaker
manufacturer, the limit levels should be adjusted so
notto exceedthe powercapabilities ofthe speakers.

In this example we are going to feed the
highs of anAERO-48 with one amplifier channel. Total
impedance of 4 M-10N high frequency drivers, as
wired in the AERO48, is 8 Ohms. The maximum rms
power to be delivered to the highs, or Pd, should be
700W(700/4=175W perdriver).

d

P =700W@8ohm

V = 700*8=74.8v

Limit level (v)=V /G=74.8/40=1.84

d

Limit level (dBu)=20log(1.84/0.775)=7.6

Important Notice: The programs stored in
the memories of the DSP-3VS have been designed to
provide optimum performance and balance between
the different ways. In order to maintain this balance,
equalgain amplifiersshould beused.

INTRODUCTION

The AERO-48 is an externally powered,
high efficiency line array module which integrates
low, mid and high frequency transducers in a
single unit. The ruggedly built enclosure is easy to
transport by means of the frontpaneldollyand the
captive rigging hardware makes flying safe and
simple. The unit is ideal for applications requiring
high sound pressure levels and precise control of
theverticalcoverage.

APPLICATIONS

The AERO-48 system is well suited for
large-scale outdoor events or indoor venues such
as theaters, arenas or stadiums. The system can
be used in conjunction with the AERO-218SUB
subwoofer unit for increased sound pressure level
inthelow frequencyrange from28Hz to83 Hz.

DESCRIPTION

The AERO-48 three-way system
incorporates two15” low frequency units with 4”
voice coils, four 8”mid-range deviceswhichutilize

2.5” voice coils and two compression drivers with
3” coils and 1.5” exit geometry. The compression
drivers are coupled to two Serpis high frequency
plane wave adaptors which insure coherent high
frequency summing and the generation of a flat,
isophasic wavefront. The components make use
of lightweight neodymium magnet assemblies for
overall weight reduction and the sophisticated
T.A.F. cooling scheme provides higher power
handlingandlow powercompression.

The trapezoidal enclosure is
manufactured from Wisa® birch plywood and is
finished in a durable catalyzed polyurethane paint.
A fabric covered steel grill protects the
loudspeaker components. The captive rigging
hardware and 5º enclosure angles permit splay
angles ranging from 0º to 9.6º in 0.8º and 1.6º
increments. Ten handles and a front panel dolly
with four heavy-duty casters facilitate
maneuvering.
