Up to four AL60/AL90 and ALi60/ALi90 loudspeakers can be flown either in vertical or horizontal arrays

The latest A-Series from d&b audiotechnik combines ‘variable splay angles with advanced waveguide design’ to address applications where coverage flexibility in both the horizontal and the vertical is paramount.

Realising the adaptability of a point source cluster with the extensive control options of a line array, the system comprises the AL60 and AL90 loudspeakers, with the ALi60 and ALi90 offering cabinets designed specifically for permanent installation.

Using the appropriate frame, up to four AL60/AL90 and ALi60/ALi90 loudspeakers can be flown either in vertical or horizontal arrays. Variable splay angles between adjacent cabinets can be set in 5° increments from –10° to +10°, allowing for fine adjustments and ensuring sound is directed more precisely to where it is wanted.

Meanwhile, midrange directivity control ensures frequencies between 200Hz and 2kHz are evenly distributed, regardless of the splay angle. With 60° horizontal dispersion and directivity control down to approximately 550Hz, the AL60/ALi60 can cover a distance of up to 30m. The AL90/ALi90 – with its 90° horizontal pattern control down to 370Hz – ensures the same optimal acoustic result is achieved more consistently, ‘anywhere and at any angle, whatever the configuration’, claims the manufacturer.

The AL60/AL90 loudspeakers share a passive two-way design featuring one 1.4-inch exit HF compression driver with a 3-inch diaphragm mounted to a wave-shaping device, and two 10-inch neodymium LF drivers. The A-Series is also compatible with d&b amplifiers and subwoofers so that the system can be tailored to meet specific application needs. The four-channel 30D, D20 and D80 amplifiers provide user-definable equalisation containing two 16-band equalisers with parametric, notch, shelving and asymmetric filters as well as delay capabilities of up to 10s. The V-GSUB and Vi-GSUB also come recommended for low-frequency extension using the A-Series.
