Martin Audio's MLA Multi-cellular Loudspeaker Array uses optimization software and a new cellular array design to "take the guesswork out of daily system design," according to R&D director Jason Baird. "We are convinced that MLA is a game-changing product."
Baird, who reported "amazingly consistent results…right from ‘switch on' during the system's recent German tour," noted that the new array represents the culmination of many years of research and development.
Promising to replace trial-and-error array design with numerical optimization of the array's output based on an acoustic model, the MLA's multi-cellular format has six individual cells in each enclosure, each with its own DSP and powering capability.
Each 24-enclosure array has 144 cells–too great a number to optimize manually or by ear. Martin Audio's Display 2.0 system design software automatically calculates FIR DSP filters for each cell and a redundant-ring audio network (U-NET) downloads the settings into each array enclosure. Martin's VU-NET software also provides real time control and monitoring of the system.
MLA features include an even frequency response and SPL over audience areas; a high system output (140dB peak, per cabinet @1m); automatic optimization of array, both physically (splay angles) and electronically (DSP); computer control and monitoring of the entire system; and control of sound system balance for engineers and sound technicians.
Additional features include 90° x 7.5° dispersion; compact dimensions (1136mm wide x 372mm high x 675mm deep), one-box-fits-all (festivals to theaters) application range and a global voltage, power factor corrected power supply.
MLA's size and output allows it to be shipped using minimal truck space. The system also includes an MLX powered, flyable subwoofer capable of a peak output of 150dB @ 1m, an MLD downfill cabinet and Merlin 4-in/10-out system controller and network hub. Audio input is via analog, AES3 or U-NET.
Martin Audio noted that MLA can be optimized for audiences at a 2,000 capacity theater, a 20,000-seat arena, or a 100,000-capacity festival site, noting the design features that promise to deliver the engineer's exact mix to every seat with a 150-meter range with precision, power and clarity.
