1. SYSTEM DESCRIPTION

The D.A.S. Audio AERO series offers two units for applications requiring precise control of the vertical coverageand highsound pressure levels.The AERO-38 is an externally powered, three-way, high efficiency linearray modulewhich integrates two 12” low frequency unitswith 4” voicecoils, two 10”midrange 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/indooreventsinarenas,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 (

2. RIGGING SYSTEM

2.1WARNING

Thismanual contains needed information for 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 tostay withinsafe 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 subjectto 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 andload variation thefollowing ratios mustbe 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 with 142 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 ifin doubt. This is important to avoid injuryand absolutelyno risks shouldbe takenin this respect. It is highly recommended that you implement an inspection and maintenance program on flying elements,including reports tobefilled outby the personnel thatwillcarryout the inspections.Local regulations may exist that, in case of accident, may require you to present evidence of inspection reports andcorrective actions after defects were 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 unsafestructures. Consult a certified professional if needed. All flying accessories that are not supplied by D.A.S. Audio are theuser's responsibility.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)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 ofthehole where the pin gets inserted.

2.2 DESCRIPTION/ACCESSORIES

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.

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 10:1safety factor,a totalamount 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.

coefficient between the

Theuse of two hoists withaloadcapacityas expressed on the previous page is mandatory. It should be kept in mind that at certain moments, the complete load may be supported by only one of the hoists.

he maximum number of AERO-38 units that can be suspended from the AX-AERO48 flying grid is 20 (with 10:1 safety factor). T

The maximum limits established by the manufacturer shouldneverbe exceeded.

This is why the load capacity of the individual hoist must be superior to the weight of the array column.

NOTE: The rigging systems of the AERO-38 and the AERO-48 are compatible. Some accessories (AXAERO38,AX-AERO48)can be used by both systems.

he maximum number of AERO-182 units that can be suspended from the AX-AERO48 flying grid is 16 (10:1).

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, then the mixer, then the processors, and finally the self-powered unit. If you have several units, it is recommended that you switchthem on sequentially one at atime.

Follow the inverse orderwhenswitchingoff, turning self-powered units off before any other elementin the sound system.

Mute all signalsourcesbefore switchingthe unitonor off.

It is recommended that the red LED indicators are not lit continuously; at most it should blinkonlyoccasionally.

If you wish to have a visual indicationat the mix position of whether the LIMIT LEDs are lighting, during equipment set-up, closely observewhat mixer VUmeter level corresponds to the level that lightsthe enclosure's LIMIT LEDs. That level that should not be exceededduring the event.

LIMIT

Due to their highefficiency, the Aero Series amplifiers generate very little residual heat and therefore do not need a fan for cooling. In normal use, theamplifier panel will be warm tothetouch.

If theunit stopsplaying (orjust the mid-high or the bass sections), the amplifier's overheating protection may be activated to protect the componentsfromthermal damage.

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.

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. Fullrange use is only recommended for applications where low SPL level and no bass reinforcement is adequate. To use it in thismode simplyplug themixer intothe enclosure's input.

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 and theSUBS.Both subsystems, AERO-182A andAERO-218A includesignal treatment in the amplifiersextendingtheir frequencyrangeup 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

processor

The connector isanoutput XLR in parallel with the input connector and is useful for daisy chaining the input signal to a number of boxes, connectingthem in parallel.

The number of units that can be linked this way depends on the output impedance of the equipment drivingthe enclosure, suchas themixer 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 theenclosure(mixer,console,etc). For instance, a mixing console with 100 ohm output impedance allowsdaisy chaining20 boxes,when the inputimpedance of the cabinets is 20Kohm.

As can be seen in the diagram, independent signal lines exist for the subwooferunits, AERO-182A. The signal that goesto the subs is processed bymeansoftheDSP-1Sub to adjust the delay betweenbothsystems.

3.12 RAIN PROTECTOR

Electronic devices can be damaged when exposed to water or moisture. AERO-38A and AERO182A/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 withadditional elements.

The rain protectors supplied with each unit havebeen manufactured with fireproof materials.

The AERO-38A's rain protector features severalsmall holes on thetopsidetoallowconvection coolingofthe amplifier.

4. ASSEMBLING AN ARRAY

4.1TRANSPORTING THE CABINETS

AERO-38 units can be transported by using the front paneldollyPL-38orbyusing 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 transportedby using the front panel dollyPL-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 havetobehung “one byone”.The first step will be to attach the AX-AERO48 or the AXAERO38 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 fronthoist sothat therear ofthe gridis ontop and the front ofthe grid atthebottom, readytoreceive the first box rolled into place by means of the PL-38 dolly platform.

The nextstep isto attach the first unitto the grid by introducing the G1A48 and G2A48 guides in the receivingpoints 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 insertedand lockedcorrectly.

Once the first unit of the array has been

attached to the AX-AERO48 or AX-AERO38, the assembly should beliftedbywayof the rearhoistuntil the wheels of the PL-38 dolly platform lift off the ground. From thispoint on, thefront hoist canbe used toliftthe box into a horizontal position.

Before installing the AERO systems it is a good idea to run a simulation using the AEROWARE program utilizing thevenue dimensions. Thisway 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.Allparts, includingthehardware attached to the enclosure,thesafetypins, etc. should be thoroughly inspected before each use. Units exhibiting deformations, cracks or any other defect shouldbe replaced with new units.

It isextremelyimportant to assurethat 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 maximumloadspecifications of the hoists tobeused.

Rigging should be carried out by experts familiar with the way the systems function and their characteristics.

On occasions, it may be convenient tohave additional tie down points to impede the array from twistingor swinging.

Once thefirst boxhas been placed at 0ºand raised approximately 75cm (30 in) the second box of the array can be rolled into place. 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.

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 this operation,twoto liftthebox and oneto fitthe G1A48 guide and safety pinsintotheupperbox.

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 isappropriate 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 tosecure the array and avoid swinging.

AERO-182 systemscanbe flown onebyone asdescribed previously!!.

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 thismethod of assembling and hoisting the array, there must be enough space to permit linking all the boxesfromthe front of the the rigginghardware.

The first step will be to attach the AXAERO48 or AX-AERO38 grid and the 2 hoists. Once this hasbeen accomplished,the gridstructure can be placed in averticalpositionbylifting the rearhoistand lowering the front hoistsothattherearofthegrid is on top and the front of the grid at the bottom, ready to receivethe first box.

Rigging points

The nextstep is toattach thefirstunit tothe

grid by introducing the G1A48 and G2A48 guides in the receivingpoints 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 insertedand lockedcorrectly.

58Aero-38 Manual del usuario/ User´s manual

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

Page 19

Once the first box is attached to the structure, the remaining boxes should be brought to the array andattachedrepeatingtheprevious steps (1 and 2) using G1A48 guides and safety pins per side making sure that the pins have been inserted and lockedcorrectly.

Proceed toattach the remaining units inthe 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 allthe unitsare attached,the completearray is readyto be hoisted.

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 safetypins in the correct angleposition. Sincethe boxesare flown, the safety pinsshouldbeintheslotof theG2A48guide.

As the array assembly is lifted (6 & 7), the PL-38platformsshouldberemoved.

Once thecompletearray hasbeenlifted into place, additional slings should be attached to secure thearray and avoid swinging.

The front motor will be used only to take up

slack inthe chain,all the weight should be on the rear hoist. When the wheels of the last enclosure are off thegroundthe array can be liftedwithbothmotors.

The complete assemblyshould begin being lifted from the rear hoist (3) so that the rear of the enclosures come together due to their trapezoidal shape. The front motor will be used only to take up slack inthe chain, allthe weightshould be on the rear hoist. Proceed in this manner until the wheels of the last enclosure are off the ground. From here on, the arraycan now be lifted with bothmotors.

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.

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, atthesame time,thePL-38platforms should be reattached. When the wheels of the lowest enclosure are firmly on the ground, the array assemblycan now be lowered using therearhoist.

4.5 ASSEMBLING AN ARRAY USING THE PLATFORM PL-48S

The PL-48S platform can be used to easily transport 3/4 units of the AERO-38; in both arc shape orstackedontheplatform.

The PL-48S platform has two types of moving pieces. One of them is fixed (PL-48S_2) and can only be swung around, the other is free (PL48S_1) and is joinedtotheplatformby way ofasafety pin. The smaller piece PL-48S_1 attaches to the front enclosure hardware andthe larger PL-48S_1 attaches tothe back:

PL-48S_2

Boxes 4-5 should be separated at the front by removing the safety pins (10) that secure the G1A48guides.

The firstgroup ofboxes hasnow beenfreed and isstackedsafely on thePL-48Splatform. Tomove the stack, slightly raise the upper group of boxes and rollawaythe lower group.

When the G1A48 pieces have been freed, they should be turned (11) and stored (12) within the corresponding box, in this case number 4, using the mechanismincluded in the rigging hardware.

Page 24

Continue lowering the systems and secure (16) thePL-48S_1pieces tothe frontrigging pointsof box3, inserting 2 safety pins ineach(17).

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 the number 4 box.

Whenever a safety pin is inserted, it is recommended that theybechecked to make surethat they are correctly attached. Pull the safety pin outward to make sure that it is in the locked position.

As in the caseofthefirstgroupof boxes, itis not necessary toremove the safety pins securing the G2A48 guideswhichdetermine splay angle.They can remain in as they are, ready for the next event. The samegoes for the AX-AERO48 grid.

The last step consists of lowering the

remaining array so thatthesafetypinscan be inserted (18) into the holes of the PL-48S_1 pieces and the platform.

B) Stacked units (MAX. 4 units):

Besides using the PL-48S platform for

transporting and flying the systems, it can also be used for ground stacking.

In theevent that 4boxes are used, they should bearrangedsothatthe splay angles do not make the platform unstable. Once the boxes are flown, they can be lowered onto the PL-48S platform by using the hoists to position the array so that the

The PL-48S_2 piece on the platform has 2 holes, the lower one offers a 0º angle between box and platform and the upper hole offers a -1.6º angle, meaningthat the box is leaning forward.

Due to the weight of the boxes, it is recommended thatthey be flown first and then lowered to the platform and stacked. For stability reasons, it is recommended that no more than 4boxes be stacked.

In order toaccessthe speakers in theAERO 182 and AERO 218Sub subwoofer units, first the grill must be removed from the box. Being AERO 182 and AERO 218Sub double 18” speakers, both speakers are connected in parallel mode resulting in a total impedance of 4Ohm. To access the amplifier for service it must be removed from the back side of the box.

The use of the DSP-3VS digital processor is highly recommended when running the AERO-38 sound system, and the use of the DSP-1Sub when running the AERO-218Sub (AERO-182). Whenever another loudspeaker management system is going to be used, it should be configured with the parameters provided by the manufacturer. Not doing so may damage the system´s speaker components and affectthe 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 are accessible from the frontpanel.

The DSP-3VS includes 10 presets that can be selectedfrom the front panel. Eachpreset memory recalls specific operating parameters for a specific DASspeakersystems.Theselectedprogramis visible ontheLCD screen located on thefrontpanel.

In this example we are going to feed the highs of AERO-38 with one amplifier channel. Total impedanceof2ND-10 high frequencydrivers,as wired in the AERO-38, is 8 Ohms. The maximum rms power to be delivered to the highs, or Pd, should be 400W(400/2=200W per driver).

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 amplifiers should be used.

Anotherformulato calculate the limiters:

8.2 LIMITER SETTINGS

8.1 DSP-3VS INSTRUCTIONS

To selecta program,turn the rotarymini-DIP switch on the frontpanellabelled“Presets”.Thename of the recalled preset will appear on the LCD screen. The first timetheDSP-3VS isconnected,thenumber1 program for the AERO-48 system will appear on the frontpanelscreen.

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 dBu appears on the frontpanelscreen.

The “Settings” button allows the user to check the savedlimitlevels. The limitlevelsappearon the screen and after 5 seconds, the preset program returnsto the screen.

Thelimit levels to be enteredshouldbeequal to or lowerthan the sensitivity of the amplifiers used. Amplifier manuals provide the sensitivity at 8 Ohms and 4 Ohms.Take into account the loadimpedance at which the amplifiers will be working when adjusting thelimit levels.

When usingamplifiers with agreater output power than that recommended by the speaker manufacturer, the limit levels should be adjusted so nottoexceed the power capabilities ofthespeakers.

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

APPENDIX LINE CONNECTION: UN-BALANCED AND BALANCED..

Thereare two basic ways to transportanaudiosignalwithmicrophoneorlinelevel:

Un-balanced line: Utilizing a two-conductor cable, it transports the signal as the voltage between them. Electro-magnetic interference can get added to the signal as undesired noise. Connectors that carry un-balanced signals have two pins, such as RCA ( ) and ¼” (6.35 mm, often referred to as ) mono. 3-pin connector suchas XLR ( )mayalso carry un-balanced signals if oneofthepinsisunused.

Balanced line: Utilizing a three-conductor cable, one of them acts as a shield against electro-magnetic noise and is the ground conductor. The other two have the same voltage with respectto the ground conductor but with opposite signs.Thenoise thatcannotbe rejected bytheshield affects bothsignalconductors in thesameway. At the device’s input the two signals get summed with opposite sign, so that noise is cancelled out while the programme signal doubles in level. Most professional audio devices use balanced inputs and outputs. Connectors thatcan carry balanced signal have threepins,suchasXLR( )and¼”(6.35mm)stereo.

The graphs thatfollow show therecommendedconnection withdifferenttypes of connectorsto balanced processor or amplifier inputs. The connectors on theleft-hand side come from asignal source, andthe ones on the right hand side go to the inputs of the processor or amplifier. Note that on the un-balanced connectors on the lefthand side, two terminals are joined inside the connector. Ifhum occurswith balanced to balanced connections, try disconnecting the sleeve (ground) on the input connector. Note that the illustrations show what should be connected to what, butthatpinlocationsonan actual XLRconnectoraredifferent.Also,pin 2 hotisassumedonXLR connectors.
