NAMM Booth# 7101. D.A.S. has announced the launch of its new Aero 20A compact powered line array system. The new system joins the third generation of Aero line arrays systems born with the introduction of the Aero 40A Advanced Line Array System (ALASTM) in 2014. Incorporating the ALASTM philosophy, the Aero 20A draws from the astounding success of the “all-purpose” capabilities of the Aero 12A, launched in 2009.
The new Aero 20A incorporates D.A.S.´s latest technical achievements in transducer design, power electronics and system management. The Aero 20A incorporates a new D.A.S. 12″ loudspeaker optimized to provide high output and reliability. A light aluminum voice coil bonded to a new fiberglass reinforced cone, an optimized magnet circuit, and a new suspension design, have contributed to the exceptional performance of the 12AN4 in terms of distortion, power handling and maximum SPL. The 12AN4´s new voice coil venting scheme is particularly effective in dissipating 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 and a new waveguide assembly developed specifically for the Aero 20A. The compression driver employs a neodymium magnet structure, a titanium diaphragm and 75 mm (3″) voice coil. The M-75N is attached to an injected aluminum waveguide optimized to provide exceptional performance in conjunction with the M-75N driver.
The Aero 20A is powered by an advanced electronics package comprising a compact Class D amplifier that combines the power supply, output stage and connectors in a single, light-weight chassis. The two channel (800 W + 400 W) amplifier makes use of the latest in switch mode technology and offers maximum performance, high predictability and immunity from intermodulation artifacts thanks to the innovative design of the Pulse Width Modulation controller.
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 to 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.
The Aero 20A is DASnetTM capable, allowing for remote monitoring and control by way of DASnetTM, the audio management application for D.A.S. powered cabinets and processors. Based on the RS-485 protocol, the DASnetTM software 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.
