D.A.S. Audio Aero 8A - Manual (Page 9)

The æro 8 A 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
D.A.S. components have been combined with
enclosures designed for rapid deployment, precise
coverage and high acoustic output.
The æro 8 A incorporates a D.A.S. 8MN, 8” low
frequency transducer. The transducer employs a
62 mm (2.5”) 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 D.A.S. M-
60N neodymium compression driver designed for
use in applications where high SPL and low
distortion are required. A pure titanium diaphragm
featuring a 50 mm (2”), 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-191 waveguide-
horn assembly.
The AX-aero8 (rigging grid) accessory is used
to fly the æro 8 A systems. To stack the æro 8 A,
use the AXS-aero8. The AX-LX212 (rigging grid)
allows the æro 8 A to be flown below LX-212R or
LX-212RA.

The easily portable and rugged enclosure is
manufactured using Birch plywood and finished
with a durable black paint. The
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 1º increments,
allowing a wide range of column curvatures to be
accomplished.

SYSTEM DESCRIPTION
LINE DRAWING
The two-way amplifier design of the æro 8 A
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 350W 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 12W 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
æro 8 A
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
æro 8A. Using powerful
Wavelet analysis to provide an accurate time-
frequency representation combined with precise
adjustment of the FIR filters, D.A.S. engineers are
able to achieve perfect time alignment.
The æro 8 A 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.
