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” midrange devices which utilize 3” voice coils and one compression driver with 4” coil and 1.5” exit geometry in a single unit.
2. RIGGING SYSTEM 2.1WARNING This manual 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.
For flying boxes and defining the splay angle, the pins must be inserted in the slot of guide 2, G2A48, whereas for stacking (stacked), the pin goes through the top hole of the guide. B) Chain hoists All units in a column will be flown from the AX-AERO48 (AX-AERO38) flying grid (bumper bar), which should be used with two hoists, one located in the front and the other in the rear.
D) PL-48S AX-AERO48 The PL-48S platform is a valuable accessory which allows up to 4 AERO-38 units to be transported in a stacked position, ready to be flown. The PL-48S is made from steel and has 4 heavy duty casters with locking brakes. AERO-38 AX-COMBO AERO-28 PL-48S The AX-COMBO is joined to the last AERO38 cabinet using G1A48 and G2A48 included steel guides and 6 quick release pins. The angle depends on the hole of the rigging structures where the pins are inserted, through the slots of G2A48.
SPLAY ANGLES USING THE AX-COMBO Pins F) QUICK RELEASE PINS Each cabinet includes 6 steel heavy duty quick release pins stored on the rear panel of the cabinets. Both systems AERO-38, and AERO-182 can be flown using steel structures located on boths sides of the cabinets. NEVER REPLACE QUICK RELEASE PINS WITH SCREWS OR OTHER ELEMENTS!!! Aero-38 Manual del usuario/ User´s manual Pins can be used to free the pieces G1A48, G2A48.
3. SELF-POWERED SYSTEMS 2.3 SAFETY FACTORS The safety factor is defined as the coefficient between the 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 safety factor, a total amount of 1,600 kg (3,527 lbs) can be flown from the 4 flying points.
3.2 AERO-182A 3.3 AERO-218A Low frequency mono-amplified system. Nominal amplifier power (RMS) 1000W. The Aero-218A is a low frequency monoamplified system. Nominal amplifier power (RMS) 2 x 1000W. Amplifier panel description: A) LIMIT: Amplifier limiter indicator lights. When lit, the level of the signal source should be reduced. B) SIGNAL: Signal presence indicator at the amplifiers' inputs. H C) ON: Indicator light for each amplifier channel. A B C D) FUSE.
3.6 SWITCH ON-OFF 3.9 ECUALIZATION 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 switch them on sequentially one at a time. The units do not need extreme EQ. Avoid high levels of gain on the equalizers.
As can be seen in the diagram, independent signal lines exist for the subwoofer units, AERO-182A. The signal that goes to the subs is processed by means of the DSP-1Sub to adjust the delay between both systems. 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 each AERO-38A and AERO-182A/218A unit.
3.13 HOW TO MAKE A PASSIVE SYSTEM INTO A SELF POWERED ONE. AERO-38 -->AERO-38A: AERO-38 passive systems come with a metallic back plate, protected by a rain protector, that features two Speakon NL8 connectors. To convert a passive system into an active one, loosen firstly the screws 11x (3.9x19Pv00) and the rain protector. Once this has been done, remove the 14 x M4x20 screws that fix the back plate to the box.
AERO-218Sub -->AERO-218A To make a passive system into an active one, firstly the back plate must be removed by unscrewing the 12 M4x20 DIN965. 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 from a passive to an active Aero Series sub.
The large 6.3mm wide faston terminal should be attached to the black wire, and the small 4.8mm wide faston terminal should be attached to the red wire: In the case of the AERO-218A the same process applies to the second amplifier in the box. Should you have any problem during this process do not hesitate to contact D.A.S. factory or our regional dealer.
3.14 TROUBLESHOOTING PROBLEM CAUSE SOLUTION No sound from the unit.

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 transported by using the front panel dolly PL-48. 4.
Lifted by way of the rear hoist until the wheels of the PL-38 dolly platform are off the ground. Swing the G2A48 guide into place and secure it with the safety pin. Lift with the front hoist until the box is in a horizontal position. 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, two to lift the box and one to fit the G1A48 guide and safety pins into the upper box.
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 boxes from the front of the the rigging hardware. The first step will be to attach the AXAERO48 or AX-AERO38 grid and the 2 hoists.
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 locked correctly. Rear hoist!! 3 5 G2A48 4 1 G1A48 The front motor will be used only to take up slack in the chain, all the weight should be on the rear hoist. When the wheels of the last enclosure are off the ground the array can be lifted with both motors.
Aero-38 Manual del usuario/ User´s manual 60
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, at the same time, the PL-38 platforms should be reattached. When the wheels of the lowest enclosure are firmly on the ground, the array assembly can now be lowered using the rear hoist.
Release the PL-48S_2 piece by removing the safety pins (1). Next, swing the pieces and introduce them (2) into the rear rigging hardware of the lowest box, securing them with the safety pin (3). Turn the piece G2A48 a few degrees to allow fixing PL-48S_2 to the rigging system G2A48 Quick release pin must be inserted in the position 0º PL-48S_2 2 1 Once the two PL-48S_2 have been attached to the boxes (3) using one safety pin per piece, the PL48S_1 pieces can be attached.
Boxes 4-5 should be separated at the front by removing the safety pins (10) that secure the G1A48 guides. 11 10 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 mechanism included in the rigging hardware. Aero-38 The first group of boxes has now been freed and is stacked safely on the PL-48S platform. To move the stack, slightly raise the upper group of boxes and roll away the lower group.
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 hardware of the number 4 box. The last step consists of lowering the remaining array so that the safety pins can be inserted (18) into the holes of the PL-48S_1 pieces and the platform.
The arrangement in the following picture is an unstable one. The smaller the splay angle between cabinets, the more the stability. Obviously, the most reliable stack in terms of stability is the one when the splay angle between all of the cabinets is 0º. -1.6º 0º 6.4º The angle between the box and the platform will be -1.6º when the safety pin is inserted in the hole on the bottom of the back guide, and the hole on top of the PL-48S_2 piece.
Now the entire cluster can be lowered so the PL-48S_1 pieces get into reach of the platform. The next step is to fix the PL-48S_2 pieces to the rear rigging hardware of the box. In order to do so, the platform should be raised up (6) till the bottom hole in the rigging hardware and the hole in the PL-48S_2 match together. Then the safety pins can be inserted (7) in the holes. As has been said before, the splay angle between the platform and the box is given by the hole used in the PL-48S_2 piece.
Lower the cluster till the platform is resting on the floor. 9 8 When the boxes are flown the safety pins must be inserted in the G2A48 slots. Now we want to stack the boxes, so the next step is to release the pins from the slots and introduce them in the G2A48 holes. It must be done by first lowering the boxes till the safety pins can be removed, then raise the boxes till the holes fit together and finally insert the safety pins again.
15 13 16 17 4.8º 14 Safety pins can now be inserted (14). In this example, the set up angle between boxes 3 and 4 is 4.8º. 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.
In order to set up the angle between boxes 1 and 2 you must pull up (23) from the grid until the hole in the G2A48 piece fits with the hole that determines the stacking angle. Then insert the safety pins (24). 23 24 1.6º 3.2º 4.8º At this point the boxes are safely stacked. Finally, the AX-AERO48 grid should be detached from box number 1.
4.6 ASSEMBLING A CLUSTER USING THE PL-48S PLATFORM AERO-38 boxes can be easily transported in groups of four when stacked on the PL-48S platform. This arrangement is also useful and saves time when setting up a cluster. Let us see what would the procedure be when flying a six box cluster. 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.
The angles that can be seen in the example are 0.8º between the first and second boxes, and 1.6º between the second and the third boxes. The cluster can now be lifted by the two motors, and the PL-48S platform detached. 3 3 The first step to detach the PL-48S platform 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.
Place the remaining group of boxes under the cluster, then lower the cluster until both front sides are in close proximity. G1A48 front guides (9) of the first box on the platform can now be swung and left in the upright position, ready to be inserted into the front rigging hardware of the next box. Lower the cluster until the G1A48 front guides fit into the rigging hardware of the bottom box and insert the two safety pins (10) per side.
With the front guides correctly secured, swing the G2A48 (11) rear guides belonging to the box on top of the second group and lower the grid till the guides fit into the rigging hardware of the next box. Set the angle between both boxes by inserting the safety pins in the correct hole. From here on, the process is similar to the previously described.
5. SUBWOOFER UNITS Externally amplified systems: An AERO-38 unit can reproduce frequencies as low as 60Hz. AERO-218Sub is the D.A.S. recommended subwoofer unit to be used along AERO-38 when subwoofers have to be ground stacked. When subwoofers are to be flown, AERO-182 is the D.A.S. recommended subwoofer. LINK LINK It is recommended that the subs' Low Pass Filter be set at 80Hz, so that the band ranging from 60Hz to 80Hz is reproduced by both the AERO-38 and the subwoofer.
6. MAINTENANCE The following is a discussion on how to access each transducer for maintenance or repair. In order to access the amplifier please refer to 3.11 section in this user's guide. In order to access de 12” speakers, you must first remove the front grill. Once the wings have been removed you can easily access the 10LMN16 speakers. In order to access the high frequency driver, two trapezoidal shape aluminium plates have been disposed on the top and bottom sides of the box.
+1 -1 -4 +3 -3 +4 +2 -2 Internal connections in the AERO-38 system. In order to access the speakers in the AERO182 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.

8.2 LIMITER SETTINGS 8. SIGNAL PROCESSING 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 affect the sound quality.

APPENDIX. LINE CONNECTION: UN-BALANCED AND BALANCED. There are two basic ways to transport an audio signal with microphone or line level: 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 ( Phono) and ¼” (6.35 mm, often referred to as jack) mono.
