Foo Fighters Headline With Martin Audio MLA At Invictus Games

Martin Audio's award-winning MLA (Multi-cellular Loudspeaker Array) PA system enjoyed its busiest weekend of the year, with two huge simultaneous London events on either side of the capital.

While rental/production company Capital Sound was fielding no fewer than 170 enclosures at the perennial Proms in the Park (Hyde Park), over in the east at the Queen Elizabeth Olympic Park, the Prince Harry inspired Jaguar Land Rover Invictus Games Closing Concert also featured MLA.

The five hour extravaganza combined a celebration of medallion presentations to the wounded, injured and sick servicemen and women who competed in the Games, backed by a full concert line up with Foo Fighters headlining and supporting acts Kaiser Chiefs, Ellie Goulding, Ryan Adams, Bryan Adams, The Vamps, Rizzle Kicks, and James Blunt.

A crowd of over 25,000 people heard Prince Harry deliver a heartfelt speech that roused the spirits of the crowd, culminating in a Mexican wave, before introducing the Foo Fighters for their triumphant return to London.

The event was promoted by AEG Live, with Capital working for site managers, Loudsound, with whom they have enjoyed a long relationship (most recently at British Summer Time in Hyde Park).

But unlike Hyde Park where sound leakage is at its most sensitive, there was optimism MLA would be able to produce an even bigger sound. "This was a totally new situation and the promoters were keen to see what we could get out of it, sound wise," says Paul Timmins, Capital Sound account manager. "[Loudsound site production manager] Dan Craig really understands audio and was confident he could achieve proper rock and roll levels."

With the closest residence still within 850' of the stage and with Vanguardia measuring propagation at four separate offsite locations, the production team was still able to hit the FOH SPL's demanded by the Foo Fighters, playing at well over 100dB(A) as the level ramped up incrementally through the day; at the same time the sound tapered off below the offsite restriction of 75dB(A) at the nearest measurement point-and recorded values as low as the mid 60's.

The main front facing PA comprised two hangs of 14 MLA per side and two MLD Downfills, while for sidefills, because of the site topography, Capital was able to field 12 MLA Compacts on one flank and 16 on the other-an asymmetric solution that worked particularly well, the company says. This enabled the shorter hang to fire into the VIP grandstand without straying beyond into the large block of apartment buildings behind.

Two Martin Audio W8LCs were deployed for center front fills and there were two masts of delays, set 245' back from the stage (midway from the site perimeter), each containing eight Martin Audio W8L Longbow enclosures. Meanwhile, 12 Martin Audio LE1200 low profile wedge monitors were provided as floor monitors onstage.

The real customization came in the 32-enclosure MLX sub array. In order to meet the Foo Fighters tour spec they deployed Philip Reynolds, who has worked extensively with Martin Audio US partner Delicate Productions and is familiar with MLA. Along with Martin Audio R&D director, Jason Baird, and Capital Sound technical manager, Ian Colville, Reynolds adapted the sub array into a Left/Center/Right design, which included cardioid elements to contain coverage, while bringing even more low-end transient attack to the central section.

Having been involved with the Foo Fighters since their Wasting Light album back in 2011, Reynolds says: "That sub design was exactly as I wanted and for the band it delivered the high impact in the mix"-a mix that was delivered by veteran sound engineer Craig Overbay, piloting a DiGiCo SD10.

But the planning of the event was to throw a final curve at the Capital Sound team as Paul Timmins says. "Although we had designed the audio for the closing concert, since we had the infrastructure already in place, at short notice we were asked to also handle the Invictus Games Opening Ceremony. We had to come up with a system we could change in a day, and throughout the opening ceremony there was an element of rapid reconfiguration as we had to make it work for every dignitary on stage."

Marty Beath, a seasoned MLA tech, was part of the crew, and this is where his MLA experience, and knowledge of the audience geometry in the MLA software, was brought to bear. "The area that became the audience zone at the Closing Concert was set out like a military tattoo," he says. "We needed a new solution for MLA which covered the competitors' section-set 20' in front of the stage-so we optimized the system in the software to use the bottom part of the main PA to cover the front.

"When Prince Harry was at a lectern in the PA zone I loaded a new snapshot in MLA which enabled us to get another 8dB of gain before feedback; so by using MLA's software to set a hard avoid I could direct the sound over the lectern, which was fantastic."

The entire production seemed more than satisfied with the levels and quality achieved, the company says. Phil Reynolds was enthusiastic: "I enjoy how far MLA has come. I was happy with the deployment, everything matched Foo Fighter specs, the PA did exactly as planned, and it's been exciting hearing the band today playing through a full MLA for the first time."

Dan Craig says, "Once again MLA displayed all we know and love about the system and delivered effective, even coverage. It's my third major park event of the summer and yet again MLA has demonstrated its flexibility to create a system design network.

"Since I have been using the system it has solved three very different problems and I am happy to be working with Ian [Colville] and the Capital team to provide the solutions which MLA enables us to implement."

And describing the concert as "a fitting end to an inspirational four days of Games," Jim King, director of events, AEG Live says: "AEG are very proud to have played our part in producing the Invictus Games Closing Concert."

Or as the Foo Fighters put it, "What a perfect way to finally return to the UK for the first time in years...it's been waaaay too long! Thanks for having us; it is truly an honor to come play for these incredible men and women...."
