The aero 20A is a 2-way powered line array system which incorporates connectivity for remote monitoring
TM and control. The unique configuration of the aero 20A Advanced Line Array System (ALAS ) incorporates a
12” transducer in a bass-reflex configuration for low-end and mid range reproduction. High frequency
reproduction relies on one D.A.S. M-75N compression driver attached to a new BPS-1912 waveguide.
Power for the aero 20A is provided by a package of integrated electronics that includes a new 1200 W
(2400 Wpeak) amplifier, advanced digital signal processing and connectivity for remote system management.
The three channel, high efficiency Class D amplifier design is equipped with a switch mode power supply
(SMPS) and a comprehensive protection package for both the amplifier as well as the components. Channel
two the mid-range with channel three powering the high frequency drivers.
The aero 20A incorporates the latest in digital signal processors. Brick wall FIR filters have been used to
provide perfect alignment between ways achieving exceptionally uniform coverage all the way down the
crossover point. Top-of-the-line AD/DA converters have been employed allowing for significant improvements
in dynamics, lower distortion and ultra-low noise levels.
TM Remote monitoring and control is provided by way of DASnet , the audio management application for
TM D.A.S. powered cabinets and processors. The DASnet software offers users instant and intuitive view of the
system status as well as control over the range of parameters of a single cabinet or a network of them.
The aero 20A enclosure is brilliant in design. Constructed using birch plywood and finished with the ISO-
Flex black paint offers excellent protection and durability. Two individual assemblies comprising the high
frequency waveguide and the carrier of the 12” woofer are made from injection molded aluminum and
attached to the front of the cabinet. A two-piece injected aluminum heat sink housing the amplifier and
related electronics is attached to the rear of the cabinet.
A robust steel grille with a powder coat finish has been used to protect the components. Stainless steel
has been employed to fasteners and parts of the new rigging system. The captive rigging system has been
designed to provide ease-of-use, safe rigging and precise aiming. Using captive links and quick-release pins,
the spring-loaded links remain positioned while rigging and prevent rattling during operation.
