INTRODUCTION
The LX-118A powered devices join the already extensive range of both self-powered and passive subwoofer versions. This compact system is ideal for combining with AERO-20A flown line arrays where bass boost is needed, but they can also be stacked. The LX-118A uses the DAS 18LXN neodymium speaker equipped with a 4" voice coil. The improved coil materials, magnet and enclosure design provide optimal results with high power, low power compression and low distortion. In addition, it offers a frequency range from 33 Hz to 120 Hz with a maximum SPL of 135 dB peak. This self-powered system incorporates an amplifier in Class D 1200 W that can feed on universal mains voltage from 100 Vac to 230 Vac. The amplification unit incorporates monitoring and remote control via DASnet™ (the audio management application for DAS Audio Group, S.L. enclosures and processors). You can choose various types of lowpass filters by DASnet™ or by the controls on the rear panel of the amplifier. It also incorporates two type settings presets for cardioid, for 2 and 3 units. As for the enclosure, it is built using birch plywood with reinforcements to eliminate resonances. Finished with a coat of DAS ISO-flex paint which adds a robust protective coating for durability. The rigging hardware is compatible with AERO-20A, allowing to hang them directly below the subwoofer unit without adapters. The enclosure incorporates front connectors for power and audio+data, DASnet™ by EtherCon connectors, which allow easy installation when used in cardioid configuration (as seen in the images below).

Rain protector
LX-118AElectronic devices can be damaged when exposed to water or moisture. The amplifiers must be
protected when installed outdoors. A rain protector is supplied with each self powered unit.LX-118A
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 outdoor installations the sound system must be protected with additional elements.
The rain protectors supplied with each unit have been manufactured with fireproof materials.
The rain protector features several small holes on the top side to allow convection cooling of the amplifier.

ON / OFF
A sound system should be switched on sequentially. Switch on the self-powered units last in your sound system (switch on the subwoofer before the mid-high system). Switch on the sound sources such as CD players or turntables, then the mixer, then the processors, and finally the self­powered unit. If you have several units, it is recommended that you switch them on sequentially one at a time. Follow the inverse order when switching off, turning self-powered units off before any other element in the sound system.
Disconnect the device by removing the mains connector from the mains socket. The mains connector and mains socket must always be freely accessible and never covered or blocked in any way. The models use a power cable equipped with a Neutrik PowerCon TRUE1 connector. Power can be daisy chained via the TRUE1 output connector (see details on product label).
IMPORTANT: Do not disconnect the unit while in use. Ensure that the device is disconnected from the mains by observing that the ON LED is turned off. Please note that the ON LED can stay on for several seconds after the mains power has been disconnected.
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 back on automatically. The unit recognised the value of mains automatically. The unit works from 80V to 260V (both rms).
Cardioid Preset
This unique feature facilitates the configuration of two or three units to create a cardioid response pattern. This is useful in situations where on-stage bass level projected from the subs needs to be kept to a minimum. To set-up a cardioid configuration with two stacked units, place the bottom unit facing the audience and the top box facing the stage. Set the controls for level, polarity and cut-off frequency identically on both units. Daisy-chain the signal from one unit to the other (do not activate the satellite output high-pass filter). Activate the Cardioid Preset button on the box facing the stage. This provides the level and phase adjustments necessary to cancel the rear projected sound waves “cleaning” the stage of unwanted bass. To assemble a cardioid configuration with three stacked units, the procedure is basically the same. Place the lower and top boxes facing the audience, the middle box facing the stage. Daisy­chain the signal, make sure the level, polarity and cut-off frequency are the same on all the boxes and lastly, activate the Cardioid Preset button on the box facing the stage.
Overload indicator
This device has a SIGNAL/LIMIT indicator. The red light indicates the signal is excessive. The indicator should not be lit continuously. This distorts the signal (quickly fatiguing your ears) and may damage the speakers.
Equalisation
The unit does not need extreme settings of equalisation to produce quality sound. Avoid high levels of gain on the equalisers. Gain values above +3 dB on a console’s EQ are not recommended.
Overheating
This equipment does not normally overheat during normal conditions of use. When overheating occurs, the unit protects itself. You should then find out why and if necessary contact an authorised dealer for technical assistance. Normally it is enough just to let the unit cool down after you have corrected the problem so that the system functions properly again.

Low Pass Filter
There are 4 cut frequencies available: 60, 70, 80 and 90 Hz. To use LX-118A onto AERO-20A, you must select the 80Hz and the cardioid preset OFF. This preset is appropriate for aligning with AERO-20A. Note: DO NOT APPLY high pass filter IN ANY
AERO-20A! The power in the low frequency of the AERO-20A must be added to the power of the LX- 118A and if we apply a High Pass filter to the AERO-20A, you will loose too much energy.
Remember that the AERO-20A has an internal High Pass at 60Hz.
Connections
The most common use will be combined with the satellite system. The use of an external delay to control and adjust the phase of the subs is recommended (with a digital processor, for example). The SUB units are linked with the THRU option setting.

LX-118A
The OUTPUT and LOOP THRU connectors are output XLR type connectors and are useful for daisy chaining the same signal to a number of boxes, connecting them in parallel.
The number of units that can be linked this way depends on the output impedance of the equipment driving the enclosure, such as the mixer 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 the enclosure (mixer, console, etc). For instance, a mixing console with 100 ohm output impedance allows daisy chaining 20 boxes, when the input impedance of the cabinets is 20K ohm.

RIGGING SYSTEM
Warning
This manual contains needed information for flying DAS Audio line array LX-118A 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 local regulations.
The working load limits in this manual are the results of tests by independent laboratories. It is the user's responsibility to 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.
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 replaced if in doubt. This is important to avoid injury and absolutely no risks should 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 personnel that will carry out the inspections. Local regulations may exist that, in case of accident, may require you to present evidence of inspection reports and corrective actions after defects were found.
Absolutely no risks should be taken with regards to public 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 fly enclosures from unsafe structures. Consult a certified professional if needed. All flying accessories that are not supplied by DAS Audio are the user's responsibility. Use at your own risk.
Description and accessories
Product improvement by means of research and development is on going at DAS. Specifications are subject to change without notice.
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 and load variation the following ratios must be met; 5:1 for steel cable slings, 4:1 for steel chain slings and 7:1 polyester slings.
Thus, an element with a breaking load limit of 1000 kg may be statically loaded with 200 kg (5:1 safety factor) and dynamically loaded with 142 Kg (7:1 safety factor).
DAS Audio line array systems, include 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 cam links are assembled to each of the structures which allow for stacking or flying of boxes. Each cabinet includes 4 secutiry pins, “PIN-8-C” type.

Stacking system
We should use the AX-118S20 accessory as shown in the figures below, for stacking AERO-20A (max 4 units) over the LX-118A (max 3 units):
The AX-118S20 accessory, as shown in the figures below, allows to assign an angle for a group of stacked AERO-20A. The central hole corresponds to 0 °, while the top hole to -3º, and the bottom hole to + 3°. In summary, the steps will be:
1. Release the front guides in the LX-118A.
2. Put a unit of AERO-20A over the LX-118A, fitting the guides at the front and insert the safety pins.
3. Ensure that the AERO-20A has unlocked the angulation (UNLOCK).
4. Lift the back of the AERO-20A and put the accessories on both sides of the box, as shown in the figures below.
5. Insert the safety pins in the holes corresponding to the desired angle.
6. Mount the other units according to the Rigging Manual of the AERO-20A

ANNEX I: Line connections: unbalanced and balanced
There are two basic ways to transport an audio signal with microphone or line level:
Unbalanced line: Utilising a two conductor cable, it transports the signal as the voltage between them. Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry unbalanced signals have two pins, such as RCA (Phono) and ¼” (6.35mm, often referred to as jack) mono. 3 pin connector such as XLR (Cannon) may also carry unbalanced signals if one of the pins is unused.
Balanced line: Utilising a three conductor cable, one of them acts as a shield against electromagnetic noise and is the ground conductor. The other two have the same voltage with respect to the ground conductor but with opposite signs. The noise that cannot be rejected by the shield affects both signal conductors in the same way. 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 that can carry balanced signal have three pins, such as XLR (Cannon) and ¼” (6.35mm) stereo.
The graphs that follow show the recommended connection with different types of connectors to balanced processor or amplifier inputs. The connectors on the left-hand side come from a signal source, and the ones on the right hand side go to the inputs of the processor or amplifier. Note that on the unbalanced connectors on the left-hand side, two terminals are joined inside the connector. If hum occurs with balanced to balanced connections, try disconnecting the sleeve (ground) on the input connector. Note that the illustrations show what should be connected to what, but that pin locations on an actual XLR connector are different. Also, pin 2 hot is assumed on XLR connectors.

ANNEX II : DASnet cables
With each system, cabling and patch panels are provided. It is very important to use the system with the intended cables to prevent electromagnetic interferences between the analog audio signal, the DASnet data and the power. Be sure to check the specifications provided by the cable manufacturer. It is also especially important when installing connectors yourself, to note that when termination is not accurate, a cable will be unable to achieve its maximum performance and could have interferences. There are 4 different types of cables:
- The main feeds which include power and a STP, CAT7 cable. These cables are named eCP_xx (xx refers to cable length, and the standard values are 3m or 20m).
- The links between cabinets (aero40A/Convert15A/LX-218CAnet), which are STP CAT7 cables. Cable code eC_09
- Power Links between cabinets.Cable code Plink1_09
- Links for RoadNet series. Power+STP CAT7. eCPk_1/eCPk_5
Important
The main feed cable eCP_xx has the following structure:
