Line array technology has revolutionized sound reinforcement, particularly for large venues
and events. Arraying several speaker cabinets vertically is a far more effective method of
delivering and directing sound. Line array‘s signal levels do not drop off as steeply with
increasing distance as is the case with conventional systems. What‘s more, their patterns of
throw are very wide despite the systems‘ lean configurations. Until recently this technology
saw limited use mainly in large, elaborate, and costly projects and installations. But with
arrival of DVA, true line array technology is now available for a wide range of portable
and permanent sound reinforcement applications.
Factoring all the many different parameters and users‘ needs into the design equation,
the dBTechnologies team of engineers developed a line array system that is easy to
configure, exceedingly light, and tremendously versatile. What‘s more, the managed
to take all these vital criteria into account without imposing limits on curving capacity
and the number of arrayed components. Called DVA, this system makes the most of line
array technology‘s considerable audio benefits.
Leveraging state-of-the-art technologies, materials, and many years experience
developing powered speaker systems, dBTechnologies has turned up a line array series
that raises the performance bar for handling, versatility, and return on investment.
dBTechnologies has a competitive edge. Our engineers‘ deep insight into power
electronics, DSP programming, acoustics, mechanics, materials, and manufacturing
practices enables us to independently develop innovative solutions in each of these
areas. Such comprehensive R&D proficiency puts us in a unique position: We are able
to transform inspired ideas into premium-quality products that deliver outstanding
performance at an unrivalled price-point.
The DVA series stands as a shining example of this all-around ability. Nowhere are
the benefits of integrated amps, active crossovers, and processor-driven control more
apparent than in DVA three-way line array units.
Fully powered units, freely scalable to setups of any size.
None of the impedance and amp channel availability
concerns associated with passive models.
Lossless signal path with no need for speaker cables.
Extremely tough yet remarkably light enclosures.
Digital controller (DSP) onboard for utmost operating safety.

The global group of dBTechnologies companies develops and manufactures individual speaker
components autonomously, and often specifically for the given application. We do not subscribe
to the practice of equalizing and optimizing speakers with elaborate technology to bring them
up to our standards. Instead, it has been our long-standing policy to build from the bottom up
components with specs tailored to deliver the best audio performance for the application.

The DVA T12 features state- of-the-art neodymium speakers and
high-performance digital amps with total of 1,410W output power.
In combination with top-drawer DSP and premium quality AD-DA
converter, it delivers high-definition sonic images with massive SPL
for large sound reinforcement applications.
Weighing just 29kg, this remarkably compact unit belies its
unobtrusive look by enabling you to set up very powerful line arrays
that deliver extraordinary performance.

Extended low-end performance
A 12“ neodymium woofer in a band-pass housing covers the low frequency range.
Remarkably powerful, it packs an assertive punch that reaches down to 60 Hz to
enable fullrange applications. The 12“ woofer is slanted inside the housing, giving
the cabinet a lean, unobtrusive look.

Accurate and awesomely efficient midrange response
The DVA T12‘s two 6.5“ neodymium midrange are placed close together to maximize
coherent coupling and response for those cr itical midrange frequencies. The
speaker resides in a sealed basket to optimize the displacement volume. This makes
the midrange even more responsive.
With a high BL factor, it reacts far faster to transients and renders each attack with
awesome accuracy. Both 6.5“ midrange are equipped with an optimized phase plug
and feed into a frontloaded horn to achieve a uniform coverage pattern.
High-definition top end
The 1“ neodymium HF dr ivers feature 1.4“ Mylar diaphragms. Exceptionally light
and responsive, they deliver richly detailed signals with remarkably linear frequency
response. Specially developed for use in line arrays, these ultra compact drivers may
be deployed in very close proximity to one another. This is essential to minimize
interference in such arrays.
The DVA T12 is loaded with three HF drivers tuned specifically for the
custom designed array horn. This combination maximizes the coupling of
the drivers‘ outputs and extends the range of the HF signal.
Consistent coverage pattern
The DVA T12 features constant directivity horns, HF drivers, and midrange speakers
optimized to deliver a uniform 100°-by-10° coverage pattern.
The DVA makes the most of two acoustical effects to help distribute SPL evenly.
One is the vector addition of individual horns‘ output, with the other being cylindrical wave formation. The coverage pattern may be adapted to suit the sound
reinforcement application by varying the length of the array and adjusting the splay
between individual components.

Ground stacks
DRK-10 and DRK-20 harnesses can also serve to stack cabinets on the ground when rigging
points are unavailable or the ceiling is too low. A special bracket adjusts the inclination down
to 7.5°. The DRK-10/20 fits perfectly on an upright DVA S30 subwoofer. Equipped with two
receptacles for quick-release pins, it is readily attached without tools.
The DVA S30 subwoofer sports two 18“ speakers, a bass reflex horn, a 3000W power amp, and
an internal DSP. (To learn more about it, see the chapter entitled Active Subwoofer).

DVA T12
Compatible with DVA T8 units:
DVA T12 and DVA T8 series housings and rigging hardware are compatible.
This means DVA T8 units may be flown right below a T12 array for use as down-fills in large
PA systems.
Compatible DVA T8’s may serve as far-fill extensions
Power Supply
The PFC switched-mode power supply allows up to four DVA T12 units
to be connected to one phase.
When connecting large systems (up to 12 units), we recommend
splitting up the power feed using a 16ACEKON adapter, tapped and
spliced to feed three weatherproofed Power-Con connectors.
