Martin Audio has unveiled the Multi-cellular Loudspeaker Array (MLA), which reportedly employs unique optimisation software together with a cellular array design to deliver coverage and consistency that the manufacturer believes far supersedes traditional touring line arrays
According to Martin, MLA can be optimised for every member of the audience from a small theatre to a large festival site, delivering the engineer’s exact mix to every seat up to over 150m away.
Described as the result of many years of intensive R&D, MLA’s methodology replaces normal array design with intelligent numerical optimisation of the array’s output based on an acoustic model. The 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, which is too great a number to optimise manually or by ear. Therefore, Martin Audio’s proprietary 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 then provides real time control and monitoring of the system.
MLA is reportedly capable of providing a maximum output of 140dB SPL peak, per cabinet at 1m, while the automatic optimisation of the array has further reduced assisted working sound technicians. These include the employing of both physical (splay angles) and electronic (DSP) parameters, computer control and monitoring of the entire system, together with total control of the sound system balance. The compact yet scalable system (1136mm wide x 372mm high x 675mm deep) provides a 90° x 7.5° dispersion angle, together with global voltage and power factor corrected power supply. The system also includes an MLX powered, flyable subwoofer capable of a peak output of 150dB at 1m, an MLD downfill cabinet and Merlin four-in/10-out system controller together with a network hub. Audio input is via analogue, AES3 or U-NET.
Martin Audio R&D Director Jason Baird explained the rationale behind the design philosophy. ‘Our primary aim with MLA was to take the guesswork out of daily system design and enable the engineer’s mix to be delivered throughout an audience with a degree of precision, consistency and repeatability not possible with traditional line arrays. Based on the results we experienced right from ‘switch on’ during the system’s recent German tour, we are even more convinced that MLA is a game-changing product.’
