By PSW Staff • January 11, 2018 D.A.S. Series 2 line arrays deployed by The Design Oasis for the 2017 MLB Allstar Pre-Game Celebration in Miami. DASaim (DAS Algorithmic Implementation Method) is a just-introduced approach that brings enhanced system optimization, in conjunction with AFMG FIRmaker technology, to D.A.S. Audio Series 2 line arrays. Specifically, it designs custom FIR filters (FIRmaker) for every cabinet in an array. The magnitude and phase response of every cabinet, and of every frequency, can be acted upon individually. The goal is meeting the long-sought objective of optimizing the complex acoustic interaction between loudspeakers to enhance the listening experience for the audience. The vertical dispersion pattern can be adapted to the user’s needs without physically having to change the height or splay angles of an array. As the name connotes, DASaim is a set of numerical algorithms that advance system performance while allowing user control of the perceived sound quality. Particularly when combined with the DASnet control and monitoring platform, user-applied EQ will produce more consistent results, including even frequency response, uniform coverage and consistent SPL throughout the defined coverage area. Specific parameters addressed include: — Controlled SPL distribution with distance — Tonal uniformity from front to back — Decreasing SPL in desired avoidance areas — Improved intelligibility — Efficient workflow All D.A.S. Aero-20A and Aero-40A users will be able to install these new filters in their systems, and without need of external multichannel processors or processed amplifiers. Completely contained within the DSP of each individual array module, the number of FIR filter channels is maximized, with equates to a significant reduction in cost, cabling, error possibility, and set-up time. Once the desired DASaim results are modeled in EASE Focus 3, the settings are exported to a CSV file and then imported into the arrays via DASnet.
