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.

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

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.
