SYSTEM DESCRIPTION

DAS Audio offers two line array systems; the

CA-28 CA-215

(mid-high) and the (low). DAS Audio
offers two line array systems; the (mid-high)
and the (low) which make up the .
They have been conceived as light, easy to use,
modular systems that, when coupled to other units
in a coherent manner allow for a resulting
equivalent linear source with high efficiency, high
directivity and extended bandwidth to 80Hz (-6dB),
in the case of the mid/hi unit. This makes
the ideal for small and medium sized
venues (up to 60m), such as theatres, concert and
conference venues, achieving great quality and
intelligibility. is also ideal for fixed installations
where the visual impact of the sound systems
needs to be minimized as far as its size and finish.
As a two-way full-range system it can be utilized
for reinforcing conferences and seminars; but for
applications requiring low frequency reinforcement
it may be combined with the system,
extending the range to 35Hz (-6dB). The use of the
DAS Audio controller is recommended.

2.5” voice coils, Neodymium magnet assemblies
and TAF cooling system for mid frequency
reproduction. For high frequencies, it incorporates

M-10N

a high frequency compression driver with
3” coil, Neodymium magnet and 1.5” exit coupled
to the DAS Audio plane wave guide, and to
a narrow coverage horn.

The plane wave adapter also serves as

a heat sink for the compression driver.

The system must be used in multiples,
otherwise line array benefits will not be
accomplished. Thus, the minimum number of

28 CA-28

units would be 4 up to a maximum of 16
units* with a 5:1 safety factor. Vertical coverage
offered by the different configurations will be given
by the splay angles (max. 10º) and the number of
boxes.

The boxes are manufactured from 15mm
Finnish birch plywood. Enclosure shape is
trapezoidal with 5º for the mid-high box. Finish is
finely textured black polyurethane paint, which is
resistant to ambient conditions. Both units
incorporate rigging on their sides for safe, easy
and quick flying or stacking; the units can be
angled vertically for wider coverages, specifically
the allowable angles are from 0º to 10º in 2.5º
increments. These features allow the user to
configure large numbers of units, depending on
the application, quickly and easily, be it stacked on
the ground on top of the subwoofers, or flown.
The steel grille is covered with an acoustically
transparent nylon fabric.

The loudspeakers used in the system feature
advanced technologies; new TAF (total air flow)
cooling systems, Neodymium magnetic circuits
which allow for important weight reductions,
titanium diaphragms for the high frequency
sections, and low-mid frequency cones
manufactured using crossed fibres and elastic
suspension that provide exceptional stability in the
vertical plane.

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.

Follow the inverse order when switching off,
turning self-powered units off before any other
element in the sound system.

It is recommended that the red LIMIT LED
indicators are not lit continuously; at most it should
blink only occasionally.

If you wish to have a visual indication at the
mix position of whether the LIMIT LEDs are
lighting, during equipment set-up, closely observe
what mixer VUmeter level corresponds to the level
that lights the enclosure's LIMIT LEDs. That level
that should not be exceeded during the event.

Overheating

Due to their high efficiency, the

aero series

amplifiers generate very little residual heat and
therefore do not need a fan for cooling. In normal
use, the amplifier panel will be warm to the touch.

If the unit stops playing (or just the mid-high or
the bass sections), the amplifier's overheating
protection may be activated to protect the
components from thermal 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
power lights.

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.

Full-range use is only recommended for
applications where not a lot of SPL is required. To
use it in this mode simply plug the mixer into the
enclosure's input.

To use it in combination with the , plug
the mixer into the input, and connect the
SATELLITE output to the s input. If you

The LOOP THRU output is an output XLR in
parallel with the input connector and is useful for
daisy chaining the input 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 (1250/Z), where Z is the
output impedance of the equipment driving the
enclosure. For instance, a 100 ohm output
impedance allows daisy chaining 12 boxes.

RIGGING SYSTEM

Warning

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 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 tear-down.

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.

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 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 250 Kg (4:1 safety
factor).

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 on this respect. It is highly
recommended that you implement an inspection
and maintenance programme 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

DAS Audio line array systems ( )
include 2 structures on each side of the box.
These are manufactured from black painted zinc
plated steel; they are affixed to an internal plate
with special crop resistant screws. Two stainless
steel guides assembled on each of the structures:
G1A (front guide) y G2A (back guide), that allow for
stacking or flying of boxes. Angles can be
changed from 0º to 10º in 2.5º increments on the

. On the , three possible angles are

CA-28 CA-215

possible that allow for flying from it and stacking
on it; 0º, 2.5º and 5º angles. To lock both guides,
the quick release safety pin supplied (6) must be
used.

The G1A front guide provides a solid
connection to the box and whatever is on top of it,
while the G2A back guide determines the vertical
splay angle (whether stacked or flown), as a
function of the hole where the pin gets inserted.

To ease the setting of the G2A guide in the
corresponding hole in the top box, each hole is
labelled with an associated angle, both for stacked
and flown applications.

For flying boxes (flown) boxes and defining the

providing several vertical aiming angles for the top

box ( only). The grid uses either one or two
pickup points, to allow for quick and easy vertical
aiming.

The pickup points will be used in conjunction
with electric hoists (motors) for load lifting. One or
two hoists shall be used, depending on array size.
Small 4 to 6 unit columns may use a single hoist.

Hoists used will be 1/2 ton when using two per
cluster, or 1 ton when using a single one. In either
case the user needs to check that the weight of
the complete array is lower than the load capacity
of the hoist.

If two hoists are used, the load capacity will be
given by the weight of the cluster divided by two:

Hoist load capacity> cluster weight/2

It must be noted that two hoists will be
required for configurations that require a large
number of units and/or need to tilt the cluster.

The grid is made from 50x30x2mm
steel tubing and is designed to handle great loads.
It features a centre reinforcement bar that is also
used for the lifting slings. The bar has a series of
holes (17) with a 2cm diameter that provide a
pickup point for the steel chain slings or the hoists.
The pickup point chosen will determine the tilt
angle of the whole array. 4 additional pickup points
exist for securing the array and prevent it from
rotating.

APPENDIX: 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 in side 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.
