MLA Compact

    • MLA Compact has been a lifesaver ... We’ve been able to make everybody happy––the audience, the acts, the city and the neighbourhood. Cooper Cannady, RMB Audio

    The multi-cellular revolution

    Every so often a new technology emerges that overtakes previous technologies — and in time replaces them. Just as line array took over from point-source clusters over 20 years ago, Martin Audio’s revolutionary award-winning Multi-cellular Loudspeaker Array [MLA] technology is reinventing the way loudspeaker arrays are configured and controlled delivering unsurpassed audience coverage and consistency without compromise to fidelity.

    MLA Compact brings this revolutionary technology to medium-scale touring and premium fixed installations ranging from musical theatres and concert halls to Houses of Worship and auditoriums.

    The versatile and scalable MLA Compact has received multiple awards for innovation and delivers performance, control and coverage consistency that brings the sound engineer and audience together in a more powerful, involving experience.

    MLA Compact is very powerful for its size and sounds great. With the predictability and controllability, it’s totally outstanding and in a class of its own. Lars Wern, DM Audio
    We wanted a system that was world-class and accepted by whatever bands and tour riders came through the venue. We knew MLA Compact would be accepted — especially with the technology being top of the line and cutting-edge, with capabilities no one else has. The sound quality is important to us and to have the system direct the output just to the audience and not the side walls, ceiling or back walls was critical in terms of maximizing the audience experience. Aaron Replogle, Control Point Technology, Project Manager
    We also wanted to provide smooth, even coverage from front to back, not just in terms of volume, but consistent tone for every seat in the room. I don’t want anyone to feel it’s too bright where they’re sitting, because it’s not fair to have people seek out certain seats in the audience so they can have a consistent tone experience. We don’t have that problem with MLA Compact. Adrian Varner, Technical Director, Gwinnett Church, USA

    Advanced sound control technology, that’s easy to use

    Some describe it as magic, but in its simplest terms each MLA Compact array has up to 120 individual acoustic elements [cells], each with its own onboard amplifier and DSP, which can be optimised by software to deliver the sound across the audience to meet the sonic goals required for any space.

    MLA technology is the only technology on the market to allow multiple sonic goals to be prioritised and optimised accordingly. For example, not only can MLA Compact generate an even sound field over the audience, it can contain it as well — significantly reducing the influence of the room.

    ‘Hard avoid’ areas ─ such as behind and below the array, ceilings, balcony edges and beyond the venue perimeter ─ can also be programmed in. Vertical coverage can even be fine-tuned electronically in-situ to cope with changing environmental conditions and last-minute changes in rigging height, without having to re-rig.

    With incredibly easy-to-use and highly accurate predictive software [DISPLAY] doing all the grunt work with the system, the engineer retains full artistic control and can enjoy mixing the show in the full knowledge that the sound created at the mix position will be heard everywhere throughout the audience.

    Such is the confidence that MLA Compact can bring, that significantly less time is spent setting up the system and less time is spent walking the room to verify results.

    During one particular scene, six highly amplified singers are elevated directly behind the centre array which mainly handles vocals. The amazing reduction in backspill of the MLA Compact masters these challenges in a very impressive way. The other aspect, of course, is MLA’s outstanding tonal quality. Georg Hentschel, System Engineer, Starlight Express, Bochum’s Stadionring
    The software was also a major plus in helping the system techs refine the system performance based on temperature and humidity in the venue as well as changing the start and stop points without re-hanging boxes. It’s a very powerful tool. Wayne Sowder, FOH Engineer

    That’s one of the key things the MLA Compact does that other systems don’t. It optimizes for the audience, not the room. The quality of the coverage is consistent from the front of the stage all the way to the back of the arena. 
Roger Dennis, Systems Engineer, RMB Audio

    Audio perfection

    MLA Compact’s ultimate accolade is its audio perfection. Pristine fidelity, vocal clarity, sonic impact and high output capability brings the sound engineer and the audience together in a powerful, involving experience.

    Put simply, MLA Compact is a sound engineer’s delight. It is incredibly clean and transparent and responsive to the smallest EQ changes. With no large-format compression drivers to harden the sound, it presents the engineer with a neutral canvas whatever the artist or music genre.

    It was my first chance to mix on the MLA Compact. It was unlike any system I’ve ever mixed on — incredible clarity yet very natural, warm sounding and powerful. E. Wayne Sowder, FOH Engineer
    I absolutely love the MLA Compact system. I mix Front of House and have found it to be the most enjoyable system I’ve ever mixed on. One of the things I continue to hear from people who come up to us, both professionals and audience members, is how smooth and clear the system is. How clear the top end is but it doesn’t hurt, there’s no harshness to it, which for me is a big selling point for this system. Adrian Varner, Technical Director, Gwinnett Church
    I have huge expectations for audio. Not just to reinforce sound, but to really make it musical. In most churches that I’ve been, none of the audio they’re running does that. The MLA Compact has outperformed my expectations. Tim Maughan, Lead Pastor, Redemption Church, Arizona

    Installation assured

    From a club, ballroom, auditorium or arena to a convention centre, theatre or House of Worship, every installation venue presents its own specific acoustic challenges that traditional line array systems fail to adequately tackle.

    Whether it’s sound leakage behind and below the array, or hard ceilings, balcony edges and rear walls that cause ‘slapback’ and high reverberation times — overcoming the acoustic challenges to ensure that every member of the audience enjoys intelligible speech and perfect music reproduction can be a thankless task. And if the audience’s audio experience is below par, then that venue — be it a church or convention centre — simply won’t ever maximise its potential.

    MLA Compact is fully-controllable, putting sound just where it is wanted and reducing it elsewhere — maximising the audience experience and minimising the negative acoustic impact of the room itself.

    It was an overwhelming success. Ed Crippen [system integrator] was taking measurements for the service and one of the things we discovered during the sermon was that the real-time intelligibility readings were off the charts. He had never seen intelligibility readings that high. Eric Johnson. Technical Director, Sun Valley Church, USA
    We think it’s fantastic and so do all the users who have come in since the installation. We’ve had several televised events in a row and maintaining the sightlines within the auditorium is wonderful. The shows have run the gamut from loud electrical music to a single mic bluegrass band, and the MLA Compact system has proved to be equally articulate and clear. Eric Annis, Production Manager and Technical Director, Lisner Auditorium, Washington DC
    I challenged the system with various optimisations to achieve the best solution, and it has really delivered; we were able to solve many problems with MLA's advanced technology, and it was absolutely the right system for the job. Georg Hentschel, System Engineer, Starlight Express, Bochum’s Stadionring

    The noise pollution solution

    In reproducing sound for many venues and outdoor festivals, there is often a conundrum: how can audience sound levels be delivered at a sufficiently high level for an immersive and rewarding experience, while at the same time respecting surrounding areas and residents?

    In the past, sound levels for the audience have often had to be held down in order to safeguard surrounding areas, but this can leave audiences and the FOH engineer unhappy and threaten the ongoing viability of such events or venues.

    MLA Compact has the ability to control noise escape beyond the site perimeter, while maintaining pristine fidelity and high sound pressure levels for the audience, meaning that FOH engineers can focus on what they do best — mixing — translating to a better audience experience too.

    The MLA Compact has been a lifesaver. This is the answer for an urban area with residences in close proximity. We’ve been able to make everybody happy — the audience, the acts, the city and the neighbourhood. MLA has been a real unifying experience. Not many people can deal with those kinds of restrictions and say they did OK, and we did smashingly well. Cooper Canady, Owner, RMB Audio
    I don’t believe there’s another PA on the market that can deliver the coverage and level that’s required without causing off-site noise. Neale Mace. MD, Entertainment Installations
    Having worked with the MLA Compact system for two years, I was confident that we could re-invent the audio systems across site, and utilise the controllability that DISPLAY software gives us to achieve even higher onsite levels, while at the same time maintaining the lowest off site levels.
