INTRODUCTION

The new D.A.S. Variant series was designed for
use in fixed installations, portable A/V, or
applications requiring high SPL and control of the
vertical coverage. The series comprises three
models, the variant 25A which features two 5”
speakers for mid-low frequencies and one
compression driver (2” voice coil and 1” exit)
coupled to a serpis-25 plane wave generator for
the high frequencies. The variant 25A model can be
used alone as a frontfill or under balcony unit for
voice reproduction. The second model is the
variant 18A bass system intended to be used in
combination with the variant 25A for applications
requiring extension of the low frequency range
below 90 Hz. The third system is the variant 112A
which has more efficiency and also bigger power
handling. It is a two way active cabinet including a
12” speaker (with 3” voice coil diameter) to
reproduce the low mid range (down to 63Hz) and
two neodymium compression drivers ( 2” voice coil
diameter) coupled to the serpis-112 horn to
reproduce the high frequency range. The serpis-
112 horn assures a nominal vertical coverage of
15º of the high frequency section.

All units are manufactured using 10/15mm
Finnish Birch plywood. The variant 25A/112A
enclosures´ shape is trapezoidal with 7.5º angles.
The variant 18A unit is rectangular. All enclosures
feature a rugged, weather resistant, polyurethane
black paint and incorporate stainless steel and
aluminum captive rigging hardware which is
designed to provide fast, simple and safe rigging
by means of quick release safety pins. Splay
angles can be changed from 0º to 10º in 1º
increments. The variant 112A is a curved source
system so the number of splay angles is restricted.

The variant 25A incorporate two Class AB
amplifiers featuring electronically balanced signal
inputs and outputs. The AC input and output link
utilize Neutrik PowerCon® connectors which allow
up to 10 units to be daisy chained at 230 V.

A three position eq switch located on the
amplifier panel allows for array effect correction
(mid and low frequencies sum in phase when
several units are assembled). This switch provides
two additional equalizations to adjust the high
frequency range.

The variant 18A incorporates one 1250 W
(continuous) Class D amplifier along with the
necessary signal treatment to perform as a sub­woofer unit. This amplifier features a high pass
filtered output at 138 Hz intended to provide signal
for the variant 25A units.

The variant 112A incorporates a two way
amplifier with a Class D power module of 500W
(continuos) for the low range, and a Class AB
power module of 100W (continuos) for the high
frequency range. The AC input and output link
utilize Neutrik PowerCon® connectors which allow
up to 6 units to be daisy chained at 230 V.

A three position eq switch located on the
amplifier panel allows for array effect correction
(mid and low frequencies sum in phase when
several units are assembled). This switch provides
two additional equalizations to adjust the high
frequency range.

The components used in the system feature
advanced technologies; new T.A.F. (Total Air Flow)
cooling systems, neodymium magnets which allow
for important weight reductions, titanium
diaphragms for the high frequency sections, and
low-mid frequency cones manufactured using
crossed fibers and elastic suspension that provide
exceptional stability in the vertical plane.

For mid-low frequencies, the variant 25A
incorporates two 5B 5” speakers with 1” voice coil
and ferrite magnet assemblies in a bass-reflex
configuration. High frequencies are handled by one
M-5N compression driver with 2” voice coil,
neodymium magnet and 1” exit coupled to one
serpis-25 plane wave adapter/high frequency horn
assembly designed by D.A.S. Audio. In order to
maintain coherent horizontal dispersion one of the
5” speakers features a low pass filter, avoiding
destructive interference between the 5” speakers
in the mid frequency range.

The variant 18A model includes one 18H 18”
speaker with 4” voice coil and neodymium magnet
assembly in a bass-reflex configuration. It can be
flown above the mid-high units or as an
independent cluster.

when employing just two or three units it may be
appropriate to lower the high frequency level. The
ARRAY EQ switch can be used to attenuate the
equalization of the very high frequencies in -3 dB
steps.

Switch ON/OFF

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.

Mute all signal sources before switching the
unit on or off.

Overload (Limit) indicators

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.

Equalization

The units do not need extreme EQ. Avoid high
levels of gain on the equalizers. Gain values above
+6 dB on a console's EQ are not recommended.

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.

Connections

The variant 25A unit can be used alone for
speech applications where low SPL is suitable. To
use it in this mode simply plug the mixer into the
input signal connector. To use it in combination
with the variant 18A unit, plug the mixer into variant
18A (INPUT) and connect the SATELLITE OUTPUT
to the signal input on the variant 25A unit.

When the variant 25A and variant 18A units
cannot be on the same cluster it is recommended
to drive each model separately from a signal
processor using a 138 Hz High Pass Filter for the
variant 25A, adding the necessary time delay if
requeired and feeding the variant 18A with the full
range signal.

Overheating

The variant 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.

The LOOP THRU connector 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 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 20 kohms.

The variant 112A can reproduce frequencies down to 63Hz , so in those applications where no high sound
pressure level is required (speech, vocals, etc) and there is no need of extending the low frequency range the
system can be installed without subwoofers. If it is required extending the low end then the variant 18A is
recommended.

In applications like live sound concerts, disco dance music, where high sound pressure level is required
double eighteen subwoofers should be used. DAS Audio recommends the LX-218CA. To align both systems
an external DSP with two different signal lines will be needed.

USING THE SYSTEM WITH SUBS

SIGNAL

INPUT

When variant 25A units are used in combination
with variant 18A subwoofers it is recommended to
plug the mixer into the variant 18A's input and then
to connect the variant 18A 138Hz high pass filtered
output to the variant 25A input.

The ratio between variant 25A and variant 18A
units that DAS Audio recommends to achieve a
correct balance is 4:1 (As it depends on the kind
of music and the application, it is subject to
changes). A level knob can be found on the variant
18A amplifier panel which allows for decreasing the
subwoofer level when less than four variant 25A
units are to be used, allowing to correct the
balance between Mid-High and Low frequencies.

If, for any reason, the Satellite Output on
the subwoofer is not going to be used to
feed the variant 25A units, then it is
recommended to make use of an external
processor to high pass filter the signal fed
into the variant 25A unit at 138 Hz, and add
the necessary time delay to match the
phase at the cut off frequency.

When using a subwoofer other than the variant
18A in combination with the variant 25A units, it is
recommended that external processor be used to
filter the signal fed into the variant 25A units at 138
Hz.
If an externally amplified subwoofer unit is to be
used in combination with variant 25A satellites, the
signal treatment will depend on the characteristics
of the subwoofer used. In order to achieve a good
quality sound, DAS Audio recommends the use of
variant 18A subwoofers.

The variant 112A can reproduce frequencies
down to 63Hz , so in those applications where no
high sound pressure level is required (speech,
vocals, etc) and there is no need of extending the
low frequency range the system can be installed
without subwoofers. If it is required extending the
low end then the variant 18A is recommended.

It is also recommended when combining
systems to use two different signal lines and one
external DSP to align both systems.

In applications like live sound concerts, disco
dance music, where high sound pressure level is

Note: the relationship between the number of
subwoofers and the number of variant 112A
depends on the application and is a parameter to

specifications are subject to change without notice.

RIGGING SYSTEM

Introduction

This section 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. Additional information is
included in the document System Guide which can
be found on the D.A.S. website.

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 D.A.S. Specifications
are subject to change without notice.

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 D.A.S. Audio are the user's responsibility. Use
at your own risk.

Accesories description

D.A.S. Audio variant 25A, variant 18A and variant
112A units include two rigging structures on each

side of the enclosure. Manufactured from stainless
steel and aluminum, they are affixed with special
M8 crop resistant screws to the wood sides on
both models. A special connecting link is part of
each rigging structure and allows for both stacking
or flying with splay angles ranging from 0º to 10º in
1º increments (variant 25A) or angles ranging from
12º to 15º (variant 112A).

In order to set up the splay angles the quick
release pins supplied with each unit must be used.

4 quick release pins are provided with variant

25A/112A and 6 quick release pins with the variant
18A.

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 142 Kg (7:1 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 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.

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.
