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.
