The AERO-20A is a compact line array system which incorporates the ALAS™ philosophy and draws from the astounding success of the “all purpose” capabilities of the AERO-12A, launched in 2009. The powered AERO-20A incorporates DAS´s latest technical achievements in transducer design, power electronics and system management.
The low-mid range incorporates a DAS 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 significantly to the exceptional performance of the 12AN4 in terms of distortion, power handling and maximum SPL.
High frequency response relies on a compression driver-waveguide assembly developed for the AERO-20A. The M-75N compression driver employs a powerful neodymium magnet structure, a titanium diaphragm and 75 mm (3″) voice coil. A reengineered mounting system which tightens internal tolerances along with a new shorting ring design have increased the power handling capacity of the driver. The M-75N is attached to a new aluminum waveguide that has been designed to be free of resonances and provide a natural sound.
