InfoComm 2019: d&b introduces A-Series augmented array loudspeakers

The all new A-Series from d&b audiotechnik introduces the augmented array: Combining variable splay angles, two approaches to acoustic optimisation, and advanced waveguide design.

The system comprises the AL60 and AL90 loudspeakers, with 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 five degree increments from -10° to +10° allowing the finest of adjustments and ensuring sound is directed precisely where required.

Midrange Directivity Control (MDC) ensures frequencies between 200Hz and 2kHz are evenly distributed, regardless of the splay angle. With 60° horizontal dispersion and directivity control down to approximately 550 Hz, the AL60/ALi60 can cover a distance of up to 30 meters. The AL90/ALi90 – with its 90° horizontal pattern control down to 370 Hz – is sonically and mechanically compatible, ensuring the same optimal acoustic result is achieved consistently anywhere, at any angle – whatever the configuration.

The AL60/AL90 loudspeakers share a passive 2-way design featuring one 1.4” exit HF compression driver with a 3” diaphragm mounted to a wave shaping device, and two 10” neodymium LF drivers. The combination of sophisticated waveguide design and the symmetrical bipolar arrangement of the LF drivers allows a smooth overlap of the adjacent frequency bands in the crossover design. The wave segments of each cabinet couple without gaps and sum up coherently.

The A-Series is compatible with a range of d&b amplifiers and subwoofers so that the system in its entirety can be tailored to meet specific application needs. The companionable four channel 30D, D20 and D80 amplifiers provide extensive user-definable equalisation containing two 16-band equalisers with parametric, notch, shelving and asymmetric filters as well as delay capabilities of up to 10 seconds. The V-GSUB and Vi-GSUB are recommended for low frequency extension using the A-Series, with many more options available for mobile and install, large or small.
