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.
Overload indicator
This device has an indicator (LIMIT LED) that lights when the signal is excessive.
The indicator should not be lit continuously. This distorts the signal (quickly fatiguing
your ears) and may damage the speakers. Therefore, it is recommended that you never
work with this LED on; at most it should blink only occasionally.
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.
ACTION-S118A and ACTION-S218A amplifiers are equipped with fan and heatsink to
maintain the correct operating temperature.
Keep grilles clean and dust-free.
Do not block or obstruct in any way the air entrance or exit while the equipment is
in use.
Air circulates from the bottom to the top of the amplifier.
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.
Therefore the current consumed by a 115V version is double the 230V version to
achieve the same acoustic power level.

Warnings
This manual contains needed information for
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 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.
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.
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.
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).
Introduction
Flyable action 500 series models feature 6
internal steel angles, with 2 mounting threads
each, so that 12 flying points are available (2 on
each side, 3 on the top panel and 3 on the bottom
panel and 2 on the rear panel). Eyebolt flying
points are factory sealed with M10 screws, which
are replaced with eyebolts on the flying points as
required. Flying with eyebolts is very economical
and safe, and is specially recommended for fixed
installations where the boxes are permanently
fixed.
The illustration shows the internal metal
hardware of an enclosure with eyebolt flying.
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.

Manual del Usuario / action 500 series / User’s Manual
RIGGING (cont'd)
Flying with eyebolts
The Allen-head screws must be removed and
replaced by M10 eyebolts on one side of the
enclosure. Each rigging point has 200 kg (440 lb)
working load limit. Then choose the slings or
chains of required load resistance and length,
bearing in mind that the length difference between
the front and back slings or chains will determine
the vertical orientation. Alternatively, the back
bottom eyebolt points can be used to provide
vertical orientation.
The ANL-2 set is an optional set of four
eyebolts and four carabiners. (Dimensions are in
milimetres).
ANL-2
Each ANL-2 eyebolt has a rated working load
of 200 kg. (440 lb). Each ANL-2 carabiner has a
working load of 330 kg (726 lb). If using other
hardware, make sure it is rated to handle the
required load.
When using eyebolts it is important to bear in
mind that the rated working load is only true for a
load applied in the plane of the eye, and is
significantly reduced for other angles. The drawing
illustrates the concept. The table shows the
variation of the working load as a function of the
load angle. In the case of the ANL-2 eyebolt, this
means that the 200 kg working load becomes 60
kg at 45 degrees. Do not use eyebolt flying if the
load angle is higher than 45 degrees.
The following illustrations show different views
on eyebolt flying for a single box. The length of the
back cables or chains determines the vertical
angle of the box.

Introduction
The AXU-ACT8 are designed for ACTION-508 and ACTION-508A enclosures.
The AXU-ACT12 are designed for ACTION-512 and ACTION-512A enclosures.
Safety Precautions
Wall plugs provided are to be used in brick walls only.
For other wall materials, source the suitable wall plug
before use.
DAS Audio is not responsible for use other than the
recommended or whether it be the result of insufficient
strength of the support structure. Use only the screws
and wall plugs supplied on surfaces that will provide
sufficient support. Do not use on surfaces such as plaster,
and gypsum. It is highly recommended and in most parts
of the world mandatory, that a safety cable be used to
secure the enclosure to the structure.
To ensure optimum safety, the installation should be
checked thoroughly at regular intervals replacing all
deteriorated elements.
Loosen the screws before reorienting the speaker.
Never force the rigging elements.

ANNEX: 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.
