INTRODUCTION

For portable live sound applications, or fixed installations in almost any type of small-mid sized venue, the
EVENT-26A Line Array has been designed to provide exceptional sound and coverage, steadfast reliability and value
beyond comparison.
The EVENT-26A Array incorporates a high frequency waveguide and horn assembly designed with the same
technology, tools and knowledge as the aero series.

Features

- Ultra-compact, lightweight powered line array

- High-efficiency Class D amplifier with SMPS Dual
voltage mains for use anywhere in the world

- 100º wide coverage

- 2 x 6.5″, 6Mi, loudspeakers in a symmetric V-shape
configuration

- Easy system configuration thanks to DAScontrolTM

- High-end 24-bit DSP with LCD screen FIR processing
technology for constant phase response FSSTM Fast Set
Splay rigging for quick deployment

EVENT-26A

EVENT-26A

The EVENT-26A is a symmetrical, ultra-compact, two-way powered line array system. Designed by DAS
engineers to deliver stunning performance and exceptional ease-of-use, the stylish polypropylene cabinet design
offers a highly portable and road-worthy system. A comprehensive range of accessories makes the EVENT-26A ideal
for small to mid-size rental and installation applications.

The EVENT-26A combines two 6.5" transducers and a single M-60 compression driver in a rugged yet lightweight
polymer cabinet. The symmetric "V" shaped configuration of the cone transducers provides consistent 100º of
horizontal coverage down to 200 Hz. The M-60 compression driver is coupled to an advanced waveguide design that
provides control of the vertical dispersion as well as precise coupling between units when used in vertical arrays.

Powered by a two-channel Class D amplifier providing 800 Wpeak power, the amp´s rear panel includes quality
Neutrik® XLR and powerCON connectors. The DAScontrolTM interface makes the preset selection for the number
of units in the array both fast and simple. An onboard DSP featuring a 24-bit high-end processor handles X-over, EQ,
delay, and limiter functions. The powerful FIR filtering technology incorporated in the EVENT-26A offers constant
phase response which translates to transparent sound and exceptional clarity, improving the listening experience.

Streamlined deployment of EVENT-26A arrays is possible thanks to the innovative FSSTM (Fast Set Splay) rigging
system developed to permit angle selection while stacked on dollies. The stainless steel rigging hardware allows
flown arrays of up to 16 units in 1º steps from 0º to 10º.

Low-frequency reinforcement for the EVENT-26A is provided by its flyable companion subwoofer the EVENT-115A.

EVENT-115A

- Active front-loaded subwoofer system

- 1 x 15″ DAS 15FW4 loudspeaker

- High-efficiency Class D amplifier with SMPS Dual
voltage mains for use anywhere in the world

- Easy system configuration thanks to DAScontrolTM
High-end 24-bit DSP with LCD screen

- EVENT-115A compatible rigging hardware

EVENT-115A

The EVENT-115A is a compact powered subwoofer system which uses a front-loaded 15” low frequency
transducer developed by DAS. Designed as the companion subwoofer for the EVENT-26A, they share a compatible
rigging system which allows the EVENT-26A to be flown from or stacked above the EVENT-115A.

The 15FW4 15" loudspeaker used in the EVENT-115A has been engineered by DAS to provide outstanding
performance and reliability. The 15FW4 speaker design has been optimized using Finite Element Analysis (FEA) and
incorporates an extended 3″ voice coil for high-efficiency and long excursion offering a power handling capacity of
1200 Wprogram. Efficient cooling is assured thanks to the 15FW4´s vented pole piece and abundant apertures in the
speaker´s back plate keeping power compression to a minimum while providing high acoustic output over extended
periods.

Driving the DAS 15FW4 loudspeaker is a cutting-edge 1200 Wpeak Class D amplifier. On the rear panel, quality
Neutrik XLR input connectors and stereo “loop thru” output connections are available to provide signal for the
EVENT-26A systems. Thanks to the digital presets accessible by way of the DAScontrol™ interface on the rear of the
cabinet, set-up of a complete systems is extremely easy.

The EVENT-115A cabinet is constructed from Birch plywood using a robust enclosure design and finished with the
DAS ISO-flex protective coating for extended durability. The rigging hardware is compatible with the EVENT-26A
allowing it to be flown directly below or stacked above the subwoofer unit. A top located pole mount socket is available
allowing the EVENT-26A to be used in a combo configuration.

RECOMMENDATIONS OF USE

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 NC3FCA connector. Power can
be daisy chained via the NC3FCB output connector
(see details on product label).

Air circulates from the bottom to the top of the amplifier.

IMPORTANT: Do not disconnect the unit while
in use.
Ensure that the device is disconnected from the
mains by observing that the display is turned off.

Overload indicator (LIMIT / INPUT CLIP)

This device has an indicator (LIMIT / INPUT
CLIP) that it is shown on the display when the signal
level 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 these two
messages engaged; at most it should blink only
occasionally.

Equalisation

It is recommended the use of a computer based
dual-channel FFT platform to view the frequency
content of signals or measure the response of the
entire electro-acoustic system, all to better make
informed decisions about the deployment and
operation of these systems.

The unit does not need extreme settings of
equalisation to produce quality sound, just select
the parameter “number of units” in the amplifier that
corresponds to the amount of systems used and
you will achieve a very good and balanced starting
point before measuring and tunning the system.

Avoid high levels of gain on the equalisers. Gain
values above +6 dB on a console’s / processor´s
EQ are not recommended.

Overheating

This equipment does not normally overheat
during normal conditions of use. When overheating
occurs, the FAN (EVENT-26A) will automatically
start working reducing the temperature of the unit.
Make sure that the rain protectors are properly
separated from the amplifier´s back plate in order to
not block the air flux thru the fan.

RIGGING SYSTEM

Warning

This manual offers all the necessary
information for flying or stacking EVENT Line
Array series systems of DAS Audio. This
information is illustrated with drawings and
required safety precautions.

To any operations related to flying a
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.

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
th e re sults of tests b y in dependent
laboratories. 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 Audio Group,
S.L. 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
clable slings; 4:1 for steel chain slings and 7:1
for 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 a system is flying, 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
yo u im pl em e n t an in s p e c ti on a nd
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 prevent 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.

Groups of four or six units are easy to transport by
truck as we will see in this manual.

Once the packaging is removed, you can see four
security locking pins on the rear enclosure´s rigging
system. These pins are going to be used to stack the
cabinets; always use the pins of the unit to attach the
one that is going to be located above it. The rigging
system of the E V E NT-26A employs a 3 point
attaching system. Use two of the pins in the front left
and right structures and the other two in the rear one.

The PL-EV26S includes 3 locking pins to stack the
first unit.

Warning: For transport, introduce the pin in

The first group with 4 units will be the superior
group, that is to say, the group where we will install
the AX-EV26.

To assembly the AX-EV26, first, remove the
cover from the stack and use the pins of the top
cabinet.

Insert the pins of the top cabinet in the dedicated
holes of the AX-EV26, as shown in the figure 8 (3
pins are needed).

Next step would be running an Ease Focus
simulation in order to know the different splay
angles between the units and the pick up position.
(pin point of the central bar).

Before attaching the chain hoist to the AX-EV26,
the user should be able to vary the splay angles
between units and modify them accordingly to the
Ease Focus 3 simulation.

ANNE X : 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
