AERO 20A

New 800 W LF + 400 W HF Class D amplifier DASnet remote monitoring and control capable New quick-rig system for easy rigging/stacking New 12AN4 loudspeaker Improved M-75N compression driver New purpose designed HF waveguide Improved overall performance and higher SPL 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 D.A.S.s latest technical achievements in transducer design, power electronics and system management. The low-mid range 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 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. The Aero 20A is constructed using birch plywood and finished with the ISO-flex coating offering excellent protection and durability. Two injected aluminum assemblies attached to the front of the cabinet comprise the high frequency waveguide and the carrier for the 12 woofer. The assemblies also dissipate heat from the components, controlling power compression. An injected aluminum heat sink housing the amplifier and related electronics is attached to the rear of the cabinet. A new captive rigging mechanism enhances
