The Aero 12A's 600 W amplifier employs third generation Class D technologies providing extended bandwidth, improved dynamic range and exceptionally low distortion. The impressively compact and lightweight amplifier design requires much less space, reducing the overall cabinet size and in turn, the total cabinet weight.
Signal processing is accomplished by way of a powerful 24 bit DSP, providing unparalleled control over critical signal parameters. Wavelet analysis which provides an accurate time-frequency representation is combined with precise adjustment of the Digital Finite Impulse Response (FIR) filters allowing D.A.S. engineers to achieve perfect time alignment, says the company.
Also new to the Aero Series of line arrays is the large format Aero 50, the evolution of the highly successful Aero 48. This externally powered, high efficiency 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 offers a number of improvements in terms of performance and weight reduction.
The low frequency reproduction is handled by two new 15GNR loudspeakers in a bass-reflex configuration. The 15GNR speaker incorporates a 102 mm (4") edge-wound flat wire (EFW) voice coil and lightweight neodymium magnet assembly maximizing the dynamic response for a deep, precise bass. A redesigned motor structure which utilizes an internal neodymium ring focuses magnetic energy in the gap where it is needed, ensures reduced magnetic leakage and lowers the component weight.
Four purpose-built 8MN, 8" cone transducers incorporating neodymium magnetic assemblies and 62 mm (2.5") voice coils are used for mid frequency reproduction.
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 featuring 75 mm (3") copper-clad aluminum EFW voice coil yields high sensitivity, low distortion and extended frequency response.
