D.A.S. Audio Launches The AERO 20A Compact Line Array

System joins new generation of DASnet capable powered line arrays

The new D.A.S. Audio Aero 20A compact powered line array; a larger version of this image is below.

D.A.S. Audio has launched the new Aero 20A compact powered line array, joining the third generation of Aero line arrays systems born with the introduction of the Aero 40A in 2014. Incorporating the company’s ALAS philosophy, the Aero 20A also draws from the success of the “all-purpose” capabilities of the Aero 12A, launched in 2009.

The Aero 20A incorporates a new D.A.S. 12-inch woofer 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 performance of the 12AN4 in terms of distortion, power handling and maximum SPL.

In addition, the 12AN4´s new voice coil venting scheme is effective in dissipating voice coil heat providing 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-inch) voice coil. The M-75N is attached to an injected aluminum waveguide optimized in conjunction with the driver.

Audio power is supplied by a compact Class D amplifier that combines the power supply, output stage and connectors in a single, lightweight chassis. The 2-channel (800 watts plus 400 watts) amplifier makes use of switch mode technology to provide high predictability and immunity from intermodulation artifacts, thanks to the innovative design of the Pulse Width Modulation controller.

Brick wall FIR filters have been used to provide optimized alignment between “ways” to achieve uniform coverage all the way down to the crossover point. High-quality AD/DA converters have been employed allowing for improvements in dynamics, lower distortion and low noise levels.

The Aero 20A is DASnet capable, allowing for remote monitoring and control by way of DASnet, the audio management application for D.A.S. powered cabinets and processors. Based on the RS-485 protocol, the software offers users instant and intuitive view of the system status as well as remote control over a range of parameters of up to 256 devices.

Enclosures are constructed of birch plywood and finished with an ISO-flex coating offering protection and durability. Two individual aluminum assemblies comprising the high frequency waveguide, and a carrier for the 12-inch 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 due 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.
