Valencia, Spain (July 9, 2009)–D.A.S. has expanded its Aero Series2 of line arrays with the large-format Aero 50, the evolution of the company’s Aero 48.
This line-array module integrates low-, mid- and high-frequency transducers in a single unit. Designed for use in large-scale events in stadiums and arenas, the Aero 50 is said to offer a number of improvements in terms of performance and weight reduction.
The low-frequency reproduction is handled by two new 15 GNR loudspeakers in a bass-reflex configuration. The 15 GNR speaker incorporates a 102mm (4-inch) edge-wound flat-wire (EFW) voice coil and lightweight neodymium magnet assembly. A redesigned motor structure, which utilizes an internal neodymium ring, focuses magnetic energy in the gap where it is needed–a move that reportedly ensures reduced magnetic leakage and lowers the component weight.
Four purpose-built 8 MN, 8-inch cone transducers incorporating neodymium magnetic assemblies and 62mm (2.5-inch) voice coils are used for mid-frequency reproduction. These components take advantage of the Total Air Flow (TAF) cooling scheme, which evacuates voice-coil heat minimizing power compression.
The high-frequency reproduction is handled by two M-75N compression drivers designed for use in applications where high SPL and low distortion are mandatory. A pure titanium diaphragm features a 75mm (3-inch) copper-clad aluminum EFW voice coil. A copper shorting ring surrounding the pole piece helps to reduce eddy current-induced distortion with the added benefit of increasing the high-frequency output by reducing the inductive rise of the voice coil. The M-75N drivers are coupled to the SERPIS’ high-frequency plane wave generator.
