Martin Audio MLA Multi-Cellular Loudspeaker Array

Martin Audio MLAOver the last decade, line arrays have become the touring standard, yet achieving consistent results in different venues remains elusive and too dependant on trial-and-error. Martin Audio MLA goes beyond line array and removes the guesswork – giving the engineer new tools to deliver greatly improved performance, coverage and repeatability.

MLA solves both consistency and set-up issues by a combination of unique optimisation software and cellular array design – enabling the sound engineer’s exact mix to be delivered throughout the audience from gig-to-gig and venue-to-venue with a degree of precision, consistency and repeatability not previously possible.

With Martin Audio MLA, audience position and venue criteria are used as a basis for intelligent, numerical optimisation of up to 144 individual acoustic cells within the array. Everything is done from an audience perspective. Firstly, the software calculates what acoustic source is required to deliver a consistent frequency response and SPL over the audience – as well as taking into account areas where sound is not wanted. Secondly, the software configures an MLA array that can generate that source. In mathematical terms this is an “inverse problem” that we solve using numerical optimisation within the software.

Having so many individually driven and optimised cells available massively increases the resolution of the array – resulting in a much more consistent frequency response and SPL throughout a venue compared to previous touring technologies.

At the heart of MLA’s optimisation process is the most accurate acoustic model of array behaviour within the industry to date.

Martin Audio installations are a massive part of Old Barn Audio’s business, as they have full sub-distributor status.
