The
AERO-
12A
compact line array system joins
the family of professional sound touring
products.
The system incorporates an impressive battery
of high tech features that take compact line array
systems to an unprecedented level of
performance. The latest in Class D power
amplification, digital processing and optimized
DAS components have been combined with
enclosures designed for rapid deployment, precise
coverage and high acoustic output.
The
AERO-
12A
incorporates a DAS
12LN4C
,
12” low frequency transducer. The transducer
employs a 75 mm (3”) voice coil and neodymium
magnet motor assembly. Effective heat evacuation
is achieved by way of the Total Air Flux (TAF)
cooling scheme which permits high power
handling and low power compression.
High frequency reproduction relies on the
exceptional characteristics of the new DAS
M-75N
neodymium comprssion driver designed for use in
applications where high SPL and low distortion are
required. A pure titanium diaphragm featuring a 75
mm (3”) copper-clad, aluminium flat-wire voice coil
yields high sensitivity, low distortion and extended
frequency response. Each motor system has a
copper shorting ring surrounding the pole piece
which effectively reduces eddy current induced
distortion with the added benefit of increasing the
very high frequency output by reducing the
inductive rise of the voice coil. The driver is
attached to a new
BPS-9010
aluminium waveguide-
horn assembly.
The
PL-12S
(steel stacking dolly),
AX-AE12S2
(rigging bumper) and
AXS-AE12
(stacking bracket)
accessories allow for any type of stacked or flown
of the
AERO-
12A
system. The
AX-COMBO12
allow
the
AERO-
12A
to be flown below other
æro series
products.
The easily portable and rugged enclosure is
manufactured using Birch plywood and finished
with a durable black paint. The
AERO-
12A’s
trapezoidal shape and rear located splay angle
adjusters keep the front spacing between adjacent
elements the same, providing the array with a
“seamless” front baffle, for improved array
performance. The captive rigging system splay
angles range from 0º to 10º and can be adjusted
in 0.5º increments from 0º to 3º, and 1º increments
from 3º to 10º allowing a wide range of column
curvatures to be accomplished.

INTRODUCTION
LINE DRAWING
The two-way amplifier design of the
AERO-
12A
sets a new industry benchmark in audio
performance, efficiency and power density. This is
made possible by employing 3rd generation Class
D technologies which have significantly improved
three key parameters, audio performance,
efficiency and weight.
The 600W amplifier provides extended
bandwidth, improved dynamic range and
exceptionally low distortion. Impressively compact
in size and light in weight, its high power density of
over 20W per cubic inch promotes an ampliifer
design that requires much less space, reducing
the overall cabinet size and in turn, the total
cabinet weight-an important attribute for flown
systems. The high efficiency of the
AERO-
12A
amplifier ensures cool operation so that no fans or
bulky heatsinks are needed.
Signal processing is accomplished by way of a
powerful 24 bit DSP providing unparalleled control
over critical signal parameters. Digital Finite
Impulse Response (FIR) filters are used in the
signal processing of the
AERO-
12A
. Using
powerful Wavelet analysis to provide an accurate
time-frequency representation combined with
precise adjustment of the FIR filters, DAS
engineers are able to achieve perfect time
alignment.
The
AERO-
12A
system is protected by two
types of limiters-an instantaneous peak limiter to
safeguard the systems against spikes and a
sonically transparent RMS limiter that controls
excessive overpowering and thermal damage to
components. This combination provides
comprehensive protection for both the speaker
components and signal electronics.
