MHA Audio Acquires Martin Audio MLA™ System

Waterloo, ONT––MHA Audio of Hagerstown, MD, an award-winning sound reinforcement and live event production company in the northeastern US, recently joined ranks with other leading audio providers who have acquired the breakthrough Martin Audio MLA Multi-cellular Loudspeaker Array system.

MHA Audio provides professional sound systems and production management services regularly for leading local promoters and event companies such as IMP Productions, Live Nation, Merriweather Post Pavilion, Pier Six Pavilion Partners, and Showcall Inc.

As part of its dynamic growth, MHA Audio has purchased the MLA System 36 (24 MLA enclosures and 12 MLX subwoofers) to fulfill the company’s busy schedule of live events. MHA recently provided their new MLA rig for the annual Capital Jazz Festival at Merriweather Post Pavilion along with shows by Maroon Five, Katy Perry, Fiona Apple, Drive by Truckers & Lucinda Williams, AVICII, Kaskade, Queensryche, Luke Bryan and other leading artists.

Commenting on the MLA acquisition, Mike Scarfe said, “MHA Audio is excited to offer the MLA System to our clients. The MLA’s ability to create a uniform response through the listening area, control coverage, and its unparalleled sonic quality sets a new standard of excellence in professional audio far beyond anything that is currently available. In addition, there are considerable cost savings with transportation. This entire MLA system, which is capable of covering most outdoor shed style venues, will fit in one 26 ft. box truck.

Martin Audio Director of North American Operations Rob Hofkamp added, “Having known Mike for over 20 years, I am thrilled to welcome him and his team at MHA to the MLA family. The combination of MLA technology and MHA’s ability to provide an uncompromising level of quality in production and support for their clients will definitely raise the bar for excellence in live audio production.”

About MLA™ (Multi-cellular Loudspeaker Array)
The result of many years of intensive R&D, MLA’s methodology replaces trial-and-error array design with intelligent numerical optimization of the array’s output based on a highly accurate acoustic model. The multi-cellular format has six individual cells in each enclosure, each with its own DSP and amplification.

With up to 24 enclosures, each MLA array has up to 144 cells — too great a number to optimize manually, or by ear. Instead, Martin Audio’s proprietary Display2™ 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 Audio’s VU-NET™ software provides real-time control and monitoring of the system.

MLA delivers a frequency response and SPL consistency never before achievable; a very high system output (140dB peak, per cabinet @1m); Automatic optimization of the array, both physically (splay angles) and electronically (DSP); Computer control and monitoring of the entire system, and total control of sound system balance for engineers and sound technicians.

MLA is fully integrated, with Class D amplification, DSP and U-NET digital audio network built into each enclosure. MLA complete systems are ready-to-use, with MLA, MLD and MLX enclosures, flying hardware, software, cabling and training all supplied. Everything needed is included. All ancillary items — from tablet PC and Merlin™ controller to network interconnects and mains distro — are also included in the complete system package. This ensures full compatibility worldwide, down to cabling and accessories.

Additional features include 90° x 7.5° dispersion; a compact size (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 compact size and very high output allows it to be shipped using smaller trucks, offering considerable savings and reduced carbon footprint. The system also includes the MLX powered, flyable subwoofer capable of an unprecedented measured peak output of 150dB @ 1m; MLD downfill cabinet, and Merlin 4-in/10-out system controller and network hub. Audio input is via analog, AES3 or U-NET.

By adopting these principles and system components MLA is optimized for every member of the audience — from a 2,000 capacity theater, to a 20,000-seat arena, to a 100,000-person festival site. It will deliver the engineer’s exact mix to every seat (up to over 150 meters) with precision, exceptional power and clarity.
