D.A.S. has revealed the Aero 20A compact powered line array system, a new addition to its line array range which was first introduced in 2014.
Incorporating a new D.A.S. 12" loudspeaker optimised to provide high output and reliability, a light aluminum voice coil bonded to a new fiberglass reinforced cone, an optimised magnet circuit, and a new suspension design, the Aero 20A promises exceptional performance regarding distortion, power handling and maximum SPL, while a new voice coil venting scheme dissipates voice coil heat, providing the speaker with a high thermal rating and low power compression.
The high frequency response relies on the M-75N compression driver, employing a neodymium magnet structure, titanium diaphragm and 75 mm (3") voice coil, attached to an injected aluminum waveguide.
A compact Class D two channel (800 W + 400 W) amplifier powers the unit, making use of the latest in switch mode technology, offering performance, predictability and immunity from intermodulation artifacts thanks to the Pulse Width Modulation controller.
Brick wall FIR filters provide alignment between ways to achieve uniform coverage all the way to the crossover point, while AD/DA converters allow for improved dynamics, lower distortion and ultra-low noise levels.
Remote monitoring and control is possible by way of audio management app DASnet, offering users instant and intuitive view of the system status as well as remote control over a range of parameters of up to 256 devices.
The Aero 20A is constructed using birch plywood and finished with the ISO-flex coating offering excellent protection and durability. Two individual aluminum assemblies comprising the high frequency waveguide, and a carrier for the 12” woofer are attached to the front of the cabinet. An aluminum heat sink housing the amplifier and related electronics is attached to the rear of the cabinet.
A new captive rigging mechanism has been designed to provide enhanced ease-of-use, allowing angle selection to be made while stacked on the transport dolly. A locking system can be triggered to secure angles between adjacent enclosures during the stacking and lifting procedures. Safe rigging and precise aiming is achieved thanks to the AX rigging system and the low-profile fly-bar that reduces the space needed between the upper rigging point and the top of the array.
