Appearing at Barclaycard Presents British Summer Time Hyde Park Festival (BST) for the fourth consecutive year, Martin Audio’s MLA PA delivered its best performance ever – thanks to new system optimisation software.

From the opening blast of Massive Attack to the closing weekend with Mumford & Sons, Take That and Stevie Wonder, the event showed that it continues to evolve in terms of technical development.

Credit for this is due to Martin Audio rental partner Capital Sound, who provided the advanced sound transmission infrastructure, including a digital returns system upgrade.

MLA appeared in various guises on the main Great Oak Stage, the second Barclaycard Stage and Sony PlayStation stage – with six areas in all featuring Martin Audio solutions. Providing technical support for Martin Audio was Chris Pyne.

Although the design configuration that has served the event so well remained, the biggest boost to the main stage sound was provided by the new beta version of Martin Audio’s Display prediction software, as well as use of the new Dante digital network devised by Capital Sound Project Manager, Robin Conway. By driving the PA with a new 16-channel AES3 I/O for Dante, giving full 96kHz operation, Capital was able to further improve MLA’s noise floor.

The impact on was confirmed by the event’s long-standing system tech Toby Donovan, who reckons that Display ‘had added significant new functionality’. ‘By using FIR filtering to improve LF control, and making some adjustments to the overall tonality of the system, MLA now sounds better than ever,’ he says.

Equally important was that it met both the on- and offsite threshold requirements of promoters AEG Live and sound consultant, Vanguardia. ‘This was despite swirling winds blowing in the direction of the measurement points,’ says Martin Audio R&D Director, Jason Baird. Of Display, he adds: ‘Optimising a full festival rig including side hangs and delays, set back to 400m to achieve these target SPL levels presented a very real challenge, which it was more than equal to.’

Supporting Baird’s meteorological observations, Vanguardia principal consultant Olly Creedy reports 100 per cent success: ‘Despite the weather, levels of up to 100dB(A) were achieved at front of house during the first gig, Massive Attack and up to 103dB(A) during the final show for Stevie Wonder.’

Finally, for this year’s set-build, MLA broke records for the speed of getting the system up in the air, tuned, with all propagation tests carried out. ‘This was because you simply don’t need to EQ this system,’ Donovan says.

After mixing Jeff Lynne’s ELO at Glastonbury two weeks earlier, veteran sound engineer Gary Bradshaw was able to turn up at Hyde Park – this time with Take That – patch into the PA and with very little adjustment produce the show. ‘I have used Martin Audio MLA several times recently and that has certainly been the case with this system – my output EQ on the left and right and sub-low were all flat, and the result was a warm, powerful array,’ he says.

He also notes similarities between both the musical make-up of his two charges as well as production crew and mixing consoles at the events: ‘But most importantly, the PA system was the same. Once again no EQ was necessary on MLA over the main outputs; the sound was clear, powerful and very even across a huge area.’

Take That spent half the show performing in front of the PA, with guest appearances from Lulu and an opera singer (also in front of the PA). ‘This can be problematic, but in this instance it was easy to place the vocals in the mix without any adjustments.’

Reviewing the system performance, he described the vocal sound as ‘warm without being muddy, with crisp highs and great detail. The sub-lows were smooth all the way down and the transition from bass to sub-low was very even. Also I was able to run the show at normal level. The sound design was such that leakage into nearby sensitive areas, like Park Lane had been kept to a minimum without compromising SPL for the audience areas.’

MLA was used for the inaugural British Summertime event in 2013, to mitigate the historic noise pollution problems and consequent neighbourhood complaints around Hyde Park. AEG Live adopted MLA to help solve this, knowing that its control could maintain an offsite level beneath the stipulated threshold, while raising the SPL considerably within the audience area.

MLA also showed its versatility, as while the sound for Massive Attack had been described as ‘thunderous’, Mumford & Sons required a more subtle and versatile approach, as did acts on the same bill like the Mystery Jets on Barclaycard stage and The Strumbellas on the Summer Stage – all playing through Martin Audio systems.

Summarising the site wide experience, Jason Baird says: ‘We were delighted with the deployment of our systems again this year. The sound of the main stage system sounded really natural.’

And Jim King, Senior Vice President of Live Events, at AEG, adds: ‘Four years into this event it is reassuring that we are still able to operate at sound levels that were once unimaginable while again keeping neighbourhood complaints to a minimum, despite the windy conditions.

‘Capital and Martin Audio continue to refine the sound system year on year, with increasingly sophisticated software, and the improvement was immediately noticeable when I walked the site before the festival began. It is this that continues to keep us ahead of the game.’

The Great Oak Stage

For the main stage, the PA inventory again comprised two hangs of 16 MLA boxes and a single MLD Downfill per side, with 12 MLA and a MLD Downfill for the side hangs.

The sub array consisted of 21 MLX boxes in a broadside cardioid array, with a further 11 enclosures back facing. Additional W8LM Line Array enclosures provided front fills, while an array of LE1500 floor monitors were provided throughout the BST season.

The main nine delay towers comprised seven MLA boxes and a single MLD Downfill, supported by 12 MLX subs while delay positions 10 and 11 deployed eight MLA Compacts.

Other stages

Martin Audio systems were also provided for several other stages. On the Barclaycard Stage, eight MLA Compacts were flown on each side with 14 WS218X subs in a LCR cardioid configuration, with four Martin Audio DD12 loudspeakers providing front fill.

The intimate 200-capacity Sony PlayStation tent was served by Martin Audio’s package of four pole-mounted MLA enclosures per side, atop an MSX power plant, covering the low end. Wedges were Martin Audio LE12JB monitors.

Stage 3 (Summer Stage), located at the south end of the park this year, featured a Martin Audio W8LC / WS218X system with three Martin Audio W8LC and three WS218X ground stacked system per side, and Martin Audio LE12JB wedge monitors.

The Bacardi Bar also featured a distributed system including 10 x Martin Audio DD6 loudspeakers. There was also a Martin Audio DD12 system in the Promoter Bar.
