The new D.A.S. Variant series was designed

for use in fixed installations, portable A/V, or

requiring and control of the
vertical coverage. The series comprises two 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 plane
wave generator for the high frequencies. The
VARIANT25A 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
rangebelow 90 Hz.

Both units are manufactured using
10/15mm Finnish Birch plywood. The VARIANT 25A
enclosure shape is trapezoidal with 7º angles. The
VARIANT 18A unit is rectangular. Both enclosures
feature a , 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
bechanged from 0º to 10º in 1º increments.

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.

F , 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 M­5N compression driver with 2” voice coil, neodymium
magnet and 1” exit coupled to one plane
wave adapter/ 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
frequencyrange.

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.

2. RIGGING SYSTEM

Manual del usuario/ User´s manual 25Variant series

2.2 DESCRIPTION/ACCESORIES

D.A.S. Audio VARIANT 25A and VARIANT
18A 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.

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
and 6 quick release pins with the VARIANT18A.

2.1 WARNING

Variant 25A

Connecting Link

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.

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
localregulations.

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.

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.

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 atyour own risk.

To facilitate the insertion of the connecting
links in the corresponding slot of the top box, each
angle has an associated pin hole which is labeled and
located on each side of the box. Highly resistant 6mm
quick release pins with a ball safety lock are used set
the angles.

B) AXC-V25

The is made from stainless steel
and has been specially designed to ceiling mount up
to 4 VARIANT 25A units. This ceiling mountaccessory
also allows for hook clamps to be fixed to it, so up to 4
boxes can be attached to truss structures. The
VARIANT25A units mustbe fixedto the ceiling mount
accessory by means of 4 M8x35 DIN912 screws.

additional items needed are the rigging bumpers.

A) AX-V25

The AX-V25 rigging grid (bumper) is made
from steel beams and is designed to handle great
loads. It features a center reinforcement bar that is
also used for the lifting slings. One chain can be used
to determine the tilt angle of the whole cluster,
depending on the hole used to attach the chain to the
center bar. The first box in the array will be attached to
the AX-25 by means of the above described
connecting links and quick release safety pins. Both
the VARIANT 25A and VARIANT 18A can be attached
to the AX-V25 bumper. Up to 20 VARIANT 25A units
can be flown from the AX-V25 bumper while
maintaining a 7:1 safety ratio.

signal processing of each VARIANT 25A unit provides
high frequency boost. The signal treatment has been
designed to provide optimum response for arrays of 6

Manual del usuario/ User´s manual 31Variant series

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 delay if
requeired and feeding the VARIANT 18A with the full
range signal.

time

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
uniton or off.

It is recommended that the red LED
indicators are not lit continuously; at most it should
blinkonly 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.

LIMIT

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
warmto 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 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.

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 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
inputimpedance of the cabinets is 20 kohms.

4. SYSTEM INSTALLATION

4.1INTRODUCTION

The VARIANT 25A unit can be installed in a
number of ways. Typically several VARIANT 25A units
would be assembled to form a line array cluster, but it
can also be used alone, as a frontfill or as an under­balcony unit. A wide range of accessories and uses
are available, and have been described in the
paragraphs below.

4.2 PLANNING/INSPECTION

4.3 INSTALLING A LINE ARRAY
SYSTEM

Whenever a cluster of only VARIANT 25A
units is to be assembled the procedure will be as
follows:

First step will be to attach the AX-V25
bumper to the hoist. The chain sling needs to be
attached to the structure using the shackle provided
with the grid. The shackle will be inserted into the hole
recommended by the EASE FOCUS software.

The next step will be to mechanically
connect the first VARIANT25A to the AX-V25. In order
to do so rotate the connecting links (1) and then insert
the safety pins through the labeled holes to select the
splay angle between the VARIANT 25A and the grid
(2). Now both connecting links must be inserted into
the receptacles on the AX-V25 (3). Once this has been
done two more safety pins have to be inserted to
secure the boxes (4). It is highly advisable to check
thatall of the safety pins have been correctly inserted.

Before installing the VARIANT 25A system
it is advisable to run a simulation using the EASE
FOCUS software utilizing the venue dimensions. This
way we can determine the needs that should be met
by the rigging structures such as hoists, cranes,
beams, rigging points, etc. Besides providing weight
information, the program also provides users with
splay angle information, safety pin positions and
coverage predictions.

It is extremely important to assure that each
and every one of the aforementioned structures is
capable of supporting a superior load than that of the
completesystem.

Inspection is the next step after planning
and acquiring all the necessary parts needed to
elevate the systems. All parts, including the hardware
attached to the enclosure, the safety pins, etc. should
be thoroughly inspected before each use. Units
exhibiting deformations, cracks or any other defect
shouldbe replaced with new units.

It is important to establish an inspection
routine for the complete rigging system before each
event or installation as well as establishing the
maximumload specifications of the hoists to be used.

Rigging should be carried out by experts
familiar with the way the system functions and their
characteristics.

On occasions it may be convenient to have
additional tie down points to impede the array from
twistingor swinging.

The basic procedure to hang the units is as
follows: rotate the connecting links (1) until the
desired angle is reached. Then introduce the safety
pins through the holes labeled with the desired angle
which should have been provided by the prediction
software EASE FOCUS (2). Now introduce the
connecting links into the receptacles of the box above
and hang the unit from the rotating point (3). Finally
introduce the safety pin that secures the unit (4). This
procedure will be repeated as many times as
enclosuresare to be assembled.

The procedure to mechanically connect the
second unit is similar. First rotate the connecting links
(5) in order to select the correct angle by means of the
safety pins (6). In this example the selected angle is
2º. Once this has been done then the enclosure must
be hung from the first box (7) and assured by means of
onemore safety pin (8).

4.4 ASSEMBLING A SYSTEM WITH
FLOWN SUBWOOFERS

The VARIANT 18A units feature integral
rigging hardware allowing them to be flown
independently or above VARIANT 25A enclosures.

The first step will be to mechanically
connect the first VARIANT 18A to the AX-V25 grid. 6
safety pins are included in the rear side of the box in
order to do so. First rotate the rear side connecting
links by 180º, and then the front side connecting links
until the VARIANT 18A AX-V25 labeled position has
been reached. After that, insert the pin through the
holelabelled VARIANT 18A AX-V25(2).

To secure the enclosure to the grid (3) two
more safety pins are needed on each side. Check that
the position of the connecting links are as shown in
the image below.

The next step will be to hang one more
VARIANT 18A unit below the first one. To do so first
both connecting links will be rotated (4), then a safety
pin will be inserted into the hole labeled VARIANT18A
(5) on the front side connecting link, and finally both
connecting links will be introduced into the rigging
hardware of the box above and secured by means of
twomore safety pins (6).

4.5 STACKING UNITS ON THE SUBS

The VARIANT 18A units feature integral
rigging hardware which can also be used for stacking
VARIANT 25A units on top of them. The maximum
recommended number of VARIANT 25A units in this
mode is 6. The splay angles available between both
enclosures are 0º, 5º and -5º.

The first step will be to mechanically
connect the first VARIANT 25A unit to the VARIANT
18A enclosure. Four safety pins, which are included in
the box, will be necessary to do so. First rotate the
connecting links (1) on the VARIANT 18A until the
desired angle is achieved and introduce the safety pin
through the hole labeled with the desired splay angle
(2). The three available angles are 0º, 5º and -5º. Look
at the label on the VARIANT 18Abox.

4.6 SYSTEM INSTALLATION USING
THE CEILING SUPPORT AXC-V25

The VARIANT 25A units can be set up as a
long array of more than four enclosures (as explained
above) or as a small array of 2, 3 or 4 units. In the latter
case the highly resistant AX-V25 grid accessory is not
necessary. Instead the AXC-V25 ceiling mount
accessory can be used to hang a cluster of up to four
units.

First attach the ceiling mount accessory to
the ceiling or a beam. Before doing so be sure that the
load bearing capability of these elements is enough.
The AX-V25will be attached to the ceiling by means of
sixnº 10 rawlplugs andsix 7 x 40 mm screws.

Before connecting the first box to the ceiling
mount accessory the two M8x30 DIN965 screws
must be removed from the VARIANT 25A and
replaced by two M8x35 DIN912.

The AXC-V25accessory can also be used as
a support for up to two VARIANT 25A units on a pole
mount accessory, on top of one VARIANT18A unit. To
do so the AXC-V25 accessory is to be used upside­down and a special pole mount adaptor must be fixed
to it by means of two M8x35 DIN912 screws, nuts
and washers. A 10º splay angle is recommended in
order to achieve a 20º vertical coverage.

When a pair of hook clamps are attached to
the ceiling mount accessory, it can be fixed to a truss

Then hang the first VARIANT 25A unit from
the wall mount accessory. The two M8x30 DIN965
screws have to be removed from each side of the box
and replaced by two M8x35 DIN912 screws.

Up to three VARIANT 25A units can be wall
mountedby means of the AXW-V25accessory.

First the accessory must be fixed to the
wall, making sure in advance that the work load of the
wall allows for it. The wall mount accessory will be
attached to the wall using six nº 10 rawlplugs and six
7x 40 mm screws.

Three different washers must be used along
the M8x35DIN912 screws and placed in the following
order-grower (lock)washer, metal washer and rubber

5. USING THE SYSTEM WITH SUBS

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 delay to match the
phase at the cut off frequency.

138Hz high pass filtered output to the VARIANT
25Ainput.

The ratio between VARIANT 25A and VARIANT18A
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.

APPENDIX LINE CONNECTION: UN-BALANCED AND BALANCED..

Thereare 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 ( ) and ¼” (6.35 mm, often referred to as ) mono. 3-pin connector
suchas XLR ( ) may also carry un-balanced signals if oneof the pins is unused.

Balanced line: Utilizing a three-conductor cable, one of them acts as a shield against electro-magnetic
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 ( ) and ¼” (6.35 mm) 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 un-balanced connectors on the left­hand 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.
