MARTIN AUDIO MAINTAINS ITS LONG RELATIONSHIP WITH MIGHTY SZIGET FESTIVAL

The long-standing relationship between Capital Sound (part of the Solotech UK Group) and the major week-long Hungarian Sziget Festival, resumed this year after the two-year hiatus.

This six-day event on the Danube—situated on the remote Hajógyári Island (Óbudai-sziget), north of Budapest—draws between 500,000-600,000 visitors, and always pulls a major list of global superstars across its stages. This year was no exception, with Dua Lipa, Arctic Monkeys, Stromae, Kings of Leon, Lewis Capaldi, Tame Impala, Nina Kravitz and Sam Fender among the many familiar faces.

As befits one of Europe’s largest musical and cultural festivals, the technical infrastructure was first class. This included Martin Audio’s multi award-winning MLA loudspeaker array, which has been a regular and reassuring sight for audiences and visiting sound crews alike on main stage since 2015.

According to Robin Conway, Solotech Senior Technical Advisor, the main stage sound design continues to evolve as the production team strives for increased perfection, once again working alongside Hungarian audio crew chief and system designer, Marci Mezei, and local Martin Audio partners, BG Event.

They were fortunate to be able to benefit once again from the huge experience of Mezei, who has been involved with Sziget since 2001, initially starting on the smallest Pesti Est stage, before working up to main stage since 2004. And he ensured the partnership with Solotech once again produced a slick outcome.

BG Event provided auxiliary support for an inventory which included nearly 200 enclosures deployed on main stage alone, along with rigging, cabling, racks, chain hoists and motor control. BG also provided additional Merlin network management systems (and distro) to support their MLA family boxes.

The main PA comprised 17 MLA per side, with a single MLD Downfill at the base of each hang. Sidefills were an equally symmetrical 15 MLA (plus single MLD Downfill) on each flank—all underpinned by 42 MLX subwoofers (in 14 x 3-high cardioid stacks). Frontfills consisted of six MLA Compact (set on alternative sub stacks) and infill wing coverage was provided by 12 MLA Compact, set in 4 x 3 high stacks.

FOH delays comprised four further MLA Compact (left and right) while four additional delay positions were set further down the field, each populated by hangs of either eight or nine MLA (with an MLD Downfill in all cases), and a pair of MLX to handle the low frequencies. This provided an aggregated cabinet count of 182 units servicing main stage.

In addition, Solotech provided all system drive and control, complete stage systems, console and RF.

Ironically, while Solotech has now perfected the onsite design over the years—and getting inventory on and off the island is a well-drilled procedure—the challenges they faced were mostly logistical in a post-Brexit, post-Covid world, as Robin Conway explained.

“It was always going to be a challenge working in Europe post Brexit and the pandemic, with inflated costs of shipping, carnet etc,” he said. “However the production team were confident in our ability to deliver the festival audio and to deal with any additions. We have a great relationship and hope it will continue beyond 2022.”

MLA again found favour with many of the visiting sound engineers. According to Marci Mezei, many commented directly to him about the quality of the PA and the enjoyable experience it gave them—including Sigrid’s FOH sound man Jan Halsvik and Dua Lipa’s Will Nicholson, while techs from Tame Impala and Stromae voiced similar approval.

Of course Sziget is only one of three major Hungarian festivals serviced by Solotech and BG Event, with Volt and Balaton Festivals, managed by the same production team, taking place earlier in the summer. “The relationship works well and we’re able to limit our shipping to a single Artic trailer from the UK for these shows,” states Conway. “The system rolls from Volt to Balaton and then returns home before re-prep for Sziget later in the summer.”

Solotech personnel supporting Marci Mezei and his team included Mark Cleator (FOH and system) and Kevan Snuggs (monitors and stage). Meanwhile, Marci Mezei commended his own crew, consisting of BG Event’s Gabor Bacskay Mazsi, who looked after system and FOH duties, and Robert Szentesi and Aleksandar Aleksandrovic who were at the stage end.

In addition to main stage, other stages equipped with Martin Audio systems provided by BG Event, included the Samsung Colosseum and TicketSwap Party Arena`.

On the former, this included 12 MLA Compact in two hangs of six, MLA Mini, 16 WSX subs and 10 MLA Compact at the delay position. For DJ monitoring they supplied four XE500 and a pair of Blackline S18+. Artists appearing included Ben Klock, Denis Sulta & Mella Dee, Eelke Kleij, Paula Temple, Honey Dijon, John Talabot, Joris Voorn, Kölsch, La Fleur, Matador, Seth Troxle, Sasha, Zioner and Joone.

For the Party Arena, where Steve Aoki was among a cast of headline DJs, they provided 18 W8L Longbow, in two hangs of nine enclosures, six W8LM, 30 SX218 subwoofers, 12 CDD-Live12 and eight WPS with iKon amps. Delay 1 featured a further 10 W8L Longbow and the second delay point was populated by 12 W8LC. Four XE500 featured among the DJ monitors.

Stated BG Event’s Szentiványi Balázs, “The Party Arena was once again a success this year and we received so much positive feedback. The old Longbow system was ideal for the electronic music genre, and the cabinets’ large format, and the additional speakers deployed, really did their job.”

World of Wonder

One of the latest exhibitions to burst onto South Korea’s burgeoning immersive art scene features soundscapes relayed by Martin Audio’s Adorn range. Caroline Moss gets lost in the experience

Most aptly for a country at the cutting edge of technology and creativity, art exhibitions, special events and commercial presentations in South Korea are increasingly drawing on immersive technology to envelop audiences in the experience. In July, the latest creation from SILO Lab. – Ambience – opened at E-Ham Campus, a new multi-room gallery in Yangpyeong-gun on the banks of the Namhangang River.

The gallery, a collection of buildings scattered throughout a landscaped garden, was established by a businessman who acquired the site a number of years ago to create a public space that would benefit the community. Joining forces with a collective of artists who collaborate as SILO Lab., the Ambience immersive exhibition featuring seven installations was commissioned to run across the galleries for a year, from July 2022.

SILO Lab.’s aim is to cross the boundaries between technology and art. “In an attempt to create experiences that have never existed at the intersection of technology and art, we constantly carry out research and express them through art,” a spokesman from the collective comments. “Our work brings interesting experiences by realising our imaginations with technology. SILO Lab.’s work has a strong theme of nature that allows digital media – which used to be distant and difficult – to become emotionally approachable and to communicate with the audience by encouraging active participation.”

Sound follows the light in Pitch Black

It follows, then, that in order to create immersive experiences that don’t appear to rely on technology to evoke an emotional response, a non-negotiable condition was that the speakers were concealed as much as possible in each of the seven installations.

SILO Lab. had decided they wanted to use Martin Audio speakers for this project having already worked with Korean distributor Samasound to install the brand at a new showroom for Kia Motors in Seoul. “They were impressed with Martin Audio

at that installation, feeling that, compared to other speakers, the Martin Audio models were small, powerful and suitable for spaces like this gallery, where they need to perform without being obtrusive,” says Wonjoo Lee, senior manager business planning, Samasound.

The exhibitions – all in separate galleries apart from two which share the same space – consist of Starglow, strands of LED strips that twinkle in the darkness, representing stars pouring their light into the infinite universe. Here, four Martin Audio Adorn A40 ultra compact speakers have been installed in the ceiling to create an aural effect of stars falling in space. These are powered by an Inter-M L800 amplifier with PreSonus HP4 four-channel headphone amplifier with monitor control.

Three Adorn A55 compact speakers and an SX110B slimline subwoofer, powered by an LEA Professional Connect 354 four-channel amplifier, have been installed in the Glowing Clouds gallery which features a huge LED wall segueing from sunsets to clear skies and aurora light displays, with artificial smoke creating a cloud effect. Here, the soundscape is focused as closely to the top of the audience’s heads as possible.

Seven more A55s powered by an LEA Connect 168 provide the soundscape for Pitch Black, which reproduces the sense of floating in a deep, dark space as the sound moves according to the direction of the light. In Horizon, a solitary lighthouse beam sweeps across the room, accompanied by dramatic music with added sound effects including a boat horn, thunder and waves. This is relayed by six Martin Audio A40s and an SX110B sub powered by LEA Connect 168 and 354 amps. 

Ripple features a backdrop of the sun seting behind a pool of water

Ripple features a backdrop of the sun setting behind a still pool of dark water into which a single drop falls intermittently. Lasers discreetly illuminate the ripples created, which are reflected back onto the walls. The accompanying soundscape – a bell tolling clearly above soft music – appears courtesy of two Martin Audio A40s, with a single Genelec 8330 Smart Active Monitor to amplify the bell and a SX110B sub powered by an LEA Connect 354 amp, while a PreSonus AR8c eight-channel audio mixer can adjust the volume according to audience presence.  

Strands of LED strips represent stars in the Starglow gallery

Finally, eight A40s can be found in the Starglow and Sparkling Ripple exhibits which take place in the same gallery, powered by an LEA Connect 168 and a Connect 354. Large water tanks and lights create the effect of ripples reflected in moonlight, while kinetic lighting is set in motion by the accompanying music. There is also a large AV room which displays a video about SILO Lab.’s history; here, Samasound has installed a pair of Genelec 8330 SAM monitors.

With a catalogue of high-end audio brands as well as a new LED department, Samasound is firmly behind the current wave of immersive art, evidenced at this year’s KOBA show where its demo room featured an immersive 7.1.4 demo with an original media art display on an LED videowall. An exciting development, then, for one of Korea’s long-established distributors and the products, tools and expertise it provides.

PILTON PARTY FOLLOWS IN THE FOOTSTEPS OF GLASTONBURY FOR MARTIN AUDIO WPL

With a frequent presence at the Glastonbury Festival site at Worthy Farm, where they service a number of stages, SWG Events also provide technical support for Pilton Party.

Although lesser known, it occupies the same site as the popular John Peel Stage—and features equally prominent headliners.

This year it was the turn of Elbow, supported by Easy Life to take the stage at Pilton Party 2022, where the same PA system that graced the Pyramid stage this year—Martin Audio’s WPL Wavefront Precision line array—was in position again, and Pyramid production manager Emma Reynolds-Taylor repeated her role.

Both bands had turned in stunning performances on Pyramid stage this year, and Pilton Party saw a reprise. Besides that, SWG Events provided sound reinforcement for Easy Life when they played the BBC Music Introducing stage at Glastonbury in 2019.

The confidence the company now has in specifying WPL is borne out by SWG head of audio, Simon Purse’s comment: “We have now done so many shows this summer with WPL that sound engineers have built confidence playing through it, and have got used to the workflow.”

On either side of the stage SWG flew 12 WPL elements, which they ran in 2-box resolution from their iKON iK42 amplifiers. Providing front fills were eight of their W8LM Mini line arrays, while 12 of their powerful Martin Audio SXH218 (2×18”) subs were designed in a monoblock across the front. And for good measure they also provided eight of their new Martin Audio XE500 stage monitors for reference sound.

Appraising the performance of the SXH218 Simon Purse said, “The sub response was brilliant … you could really feel it from the kick drum, and we achieved 100dBa at FOH, with no complaints.”

So powerful was the main system that no delays were required to boost sound at the back. “The field itself extended to 110m and WPL comfortably threw to the 90 metres necessary for the audience coverage area,” he confirmed.

Elbow FOH engineer, Danny Evans, also registered a positive experience aboard the Martin Audio PA. “There was plenty of headroom, with impressive clarity, and the coverage was good with consistent level and even tonality around the whole audience area. This allowed me to focus on, and enjoy mixing Elbow’s show.”

Emma Reynolds-Taylor added her own endorsement. “When we were going over the specs with our supplier, SWG, to sign off on all the tech, I was happy to see they proposed this audio system, as we’re always really pleased with the results on Pyramid. We have a vast variety of acts, of all stages of their career, at Pilton Party, and the for all acts throughout the day was exceptional.”

Summarising his own experience of the event, Simon Purse said, “This was our last green field site of the year, and it was great to go out on a high.”

FOH on systems and support bands was freelancer Dan Wooles, while the stage team was headed by Joe Bailey (monitor engineer) and responsible for patch was Fraser Wilks—both from SWG.

WPL MAKES AUSPICIOUS PRESTON PARK DEBUT FOR BRIGHTON AND HOVE PRIDE

Heavily supported by the local City Council, Brighton & Hove Pride—a celebration of Brighton’s LGBTQ+ community, annually attracts crowds of around 250,000 people to the seaside resort.

While the origins of the event date back to 1973 Capital Sound (part of the Solotech UK Group) has provided main stage sound reinforcement for the last three events. Having supplied PA and control for headliners Britney Spears and Kylie Minogue, following a break for COVID they were back in the 63-acre Preston Park site for the 2022 edition which featured Christina Aguilera and Paloma Faith as headliners on the Saturday and Sunday respectively.

After deploying Martin Audio’s award-winning MLA loudspeaker array for Britney Spears back in 2018, the enforced break caused by the pandemic had enabled the British manufacturer to move the ground-breaking control technology further still, now enabling the production company to deploy the new Wavefront Precision (WPL system) that proved such a hit this summer at the UK’s two predominant Glastonbury and BST Hyde Park festivals.

Working alongside production manager Dean Parker, at Wilde Ones International Events, their sound design was based around main hangs of 18 WPL per side, with a stage right side hang of six of the smaller WPC, and a larger drop of 12 WPC elements stage left.

Maintaining continuity with Martin Audio’s Wavefront Precision family, filling the sound at the front of the stage were eight WPS, while providing the all-important low frequency extension were 20 of Martin Audio’s ultra-powerful 2×18” SXHF218 subwoofers, designed in a castellated cardioid broadside array across the front of the stage.

Stage monitoring comprised further Martin Audio systems in the shape of 16 x LE1500 floor wedges, four SXHF218 and six TORUS T1215 constant curvature arrays.

The coverage was completed by three delay masts set 70 metres back from the stage. These comprised a further 24 WPS divided over the three positions, underpinned by three SXHF218 subs on each mast, this contained the sound within the audience area, as a fairground carousel at the rear provided a buffer between this zone and the dance tent behind.

Solotech worked alongside Robert Miller of F1 Acoustics to achieve both the onsite and offsite sound thresholds, with audio crew chief and system tech, Joseph Pearce optimising the sound in Martin Audio’s DISPLAY software. He was supported by FOH tech, Alistair Hellard.

Miller had taken the precaution of modelling the sound to establish proof of concept although having experienced WPL while carrying out similar duties on the Pyramid stage at Glastonbury, he had no qualms about sanctioning the upgrade from MLA.

As for the new deployment, Solotech senior project manager, Martin Connolly, stated, “Although I have a balanced view, having provided an alternative system in 2019 at the request of Kylie Minogue’s sound engineer, I know wherever there is a sensitive site such as this, which manufacturer will be better! In fact we even managed to achieve superior figures with WPL than we had with MLA!

“Once I had explained to Dean Parker that outstanding results had been achieved at both Hyde Park and Glastonbury with WPL, he was more than happy to run with it.”

For Joseph Pearce this was his first experience driving Wavefront Precision for all hangs on an event of this size. “And it worked really well,” he confirmed. “The software-based techniques we use to reduce offsite noise levels are the same as those we use with MLA … so all the tricks Capital Sound have learnt over the years at events such as BST in Hyde Park and others could be used with the WPL and WPC hangs in Preston Park.”

Stage right was clearly the more noise sensitive area as it was closer to residences and shops, requiring constant level adjustments of both side hangs and delay hangs during the day. “In addition, as part of a site-wide strategy, all speaker hangs utilised the ‘Hard Avoid’ feature of DISPLAY 2,” he confirmed. “This kept both our coverage and non-coverage areas clearly defined and reduces unwanted internal reflections from food and beverage vendors and other structures found at the end of audience areas.”

Following propagation tests, Pearce and Miller agreed to run the earlier acts at lower SPL levels—to obviate any complaints when the event is not at it busiest—before opening the system up to the maximum in the evening. “I knew that if we could achieve 100dB LAeq15 or more in an area as densely populated as Brighton, not only I would happy but sound engineers would be happy too.”

Robert Miller was also unequivocal in his praise for the system. “The performance and configurable options of WPL meant that less time needed to be spent adjusting the system to achieve the offsite music noise 

level limits and more time could be spent focusing on delivering great sound levels at all stages. The WPL line array, and the professional installation and management by Capital Sound, gave us confidence that the off-site music noise level was under control at all times.”

Consequently the event, which generates around £20m for the city economy annually, was once again an unqualified success.

MARTIN AUDIO WPL KEEPS PACE WITH FAST-MOVING CARFEST SOUTH

Now 11 years old, Chris Evans’ popular CarFests show no signs of running out of gas, as some 50,000 people again took to Laverstoke Park Farm near Overton, Hampshire—owned by 1979 Formula One World Champion, Jody Scheckter—for CarFest South. Inaugurated by Evans back in 2011, the event raises funds for Children in Need.

The event is a regular client of Martin Audio partner SWG Events, the south-west-based production company, who provided a full sound and light package. This included their market leading Martin Audio WPL line array, which provided sound reinforcement for a broad range of artists. These included Kaiser Chiefs, Rag ‘n’ Bone Man, Tom Odell, Sophie Ellis Bextor, Faithless Soundsystem, James Blunt, Judge Jules, Bob Marley Revival and Rick Parfitt Jnr, Paloma Faith and Steps.

The fast-moving performance area is built around three differently configured stages—flanking a DJ stage occupied by Chris Evans himself—all set in a line.

SWG Events have traditionally deployed their W8LC but this year that older Martin Audio system was redeployed to delay duties—in two hangs of eight—as their new Wavefront Precision (WPL) took pride of place. The two main hangs of 12 WPL were driven in 2-box resolution from iKON iK42 process controlled amplifiers, as were a stage right out hang of 12 WPL. An additional six-per-side WPC provided infills between the stages, while across the front, 20 Martin Audio SXH218 subwoofers were set in a broadside array to provide LF extension.

Further to that, four stacks of two W8LC were deployed for front fill on the larger of the stages with an additional 16 W8LM for front fill across the lip of the smaller two. Finally, 32 XE500 Martin Audio stage wedges were placed across the two main performance stages.

With two stages constantly flip-flopping this was a high energy show—as SWG’s Simon Purse, who had overall responsibility for the audio, explained. And with many of the acts bringing their own sound engineers and control the FOH position was well populated with mixing desks.

SWG put out an experienced crew, with Ryan Bass and Adam Andrews at FOH, providing mixing duties where necessary, while Matt Pope and Olly Hayward patrolled the stage. Overall project manager was Ian Williams.

Although the two-day festival was prone to sudden weather changes, the PA coped admirably and the sound crew were able to achieve levels up to 98dBa at FOH, while observing the offsite threshold of 65dB. These were set by noise consultant Simon Joynes of Joynes Nash Acoustic Consulting.

Stated Simon Purse, “We do a lot of work with Joynes Nash; they are familiar with MLA [the precursor of Wavefront Precision] and realise it’s a useful tool for councils when it comes to environmental noise on sensitive sites.”

He added that since SWG Events acquired WPL at the beginning of the summer the system has never been in the warehouse. “It’s absolutely proved its worth and has been out nearly every weekend since we purchased it. We are now able to appease local councils as well as satisfying guest sound engineers.”

Summarising CarFest, he said, “The site is challenging because it is so large, and having all stages running more or less simultaneously and sharing the same PA, certainly keeps everyone engaged. But we pulled it off … WPL worked really well, and we will certainly use it again here.”

Simon Joynes agreed. “This system deployment continues to deliver benefits in offsite noise control, measured against comparable events,” noted the consultant.

Flower Power

Sue Su reports from the China Flower Expo in Shanghai, which has spent several months operating as a Covid field hospital

Founded in 1987, the China Flower Expo is the leading national floral and botanical event in the country. The 10th Flower Expo was held in 2021 in and around Dongping Forest Park in the Chongming District of Shanghai, a 10km2 garden space, before the site was requisitioned as a field hospital for a wave of Covid infection that hit the city in March.

The PA system for such a large area as the Flower Expo Park needed to be highly reliable, as well as providing clarity and accuracy. The Flower Expo committee, together with various government bodies organising the event, chose a TOA system supplied by Shanghai-based TOA China, which also provided full audio technical support. The company designed an all-IP digital network broadcasting system and an IP intercom system covering the indoor and outdoor exhibition areas and service facilities of the entire Flower Expo Park, to broadcast daily announcements and calls for missing people and lost property, as well as emergency services including evacuation and fire alarm.

TOA’s IP-1000 IP network audio management system was chosen for the project, with an IP-1000SM management host handling both broadcasting and intercom functions. The IP-1000SM forms a huge digital network encompassing IP network microphones, IP audio interface units, IP power amplifiers and speakers through switches based on the TCP/IP Ethernet protocol.

“The project required the broadcast loop for all outdoor zones and indoor venues to use an all-digital IP architecture,” explains TOA engineer, Shi Xiao Dong. “The central security control centre has the highest level of access and can control the audio content and volume of each broadcast zone using visualisation software, as well as the amplifiers of each sub-control centre. The project required the outdoor talkback terminals and visual alarm terminals of the IP intercom system to be connected to the IP broadcasting system through the LAN (local area network) in the Expo Park, so that they can be coupled together. This posed huge technical challenges for system control management, as well as for alignment. TOA technical engineers relied on the technical features and software of the TOA IP network system to solve these problems one by one.”

Housing four exhibition halls, the 30,000m2 Fuxing Pavilion was the Flower Expo’s main venue. With a classical Chinese sloping roof and colonnades, it has remained as a permanent building after the Flower Expo finished, and it was this building that was converted into a field hospital with more than 2,700 beds.

The Fuxing Pavilion’s computer room is in the central security control centre; the main computer room of the entire park and the location of the IP-1000SM system host. The room is also equipped with an IP-1000CI to receive alarm signals from the fire centre. If a fire occurs, emergency evacuation voice broadcasts are triggered for individual venues or the entire park. An IP-101RM IP network microphone is used for real-time announcements, with other external sources received via the IP-1000AF IP audio interface unit through the IP network. Signals are then output from the IP-1000AF to 78 A-3248D power amplifiers, 91 PC-1868D-CH ceiling speakers and 185 BS-1006 wall-mounted speakers for voice evacuation broadcast. The IP-101RM IP network microphones and N-XC90VS2 IP intercom terminals forming the intercom system can be connected to work in tandem with the IP broadcasting system.

The 1,200m2 Century Pavilion, resembling a colourful butterfly, and 400m2 Bamboo Pavilion surrounded by bamboo and rattan and shaped like an oval cocoon, also use IP-1000AFs to output audio sources to A-3248D amps and CS-64 waterproof speakers. Three temporary venues, the flower art museum, Huaqi Hall and Baihua museum, were also installed with IP-1000AFs and A-3248D amps, with a total of 100 PC-1868D-CH ceiling speakers and nearly 200 BS1006 wall-mounted speakers between them.

In a large outdoor area outside the Fuxing Pavilion, IP-100XI IP audio input modules receive their audio signals from the system software, sending them to the AX-0240 amps driving TZ-406BWP column speakers and GS-301D-CH outdoor speakers. The intercom terminals include the camera-equipped N-XC85AS2 and N-XC90VS2 models, coupled to the IP broadcasting system.

“The Flower Expo project combines the advantages of TOA’s IP network broadcasting system and IP intercom system,” concludes TOA’s marketing manager, Ding Wei. “The system is not only equipped to handle the daily announcements, but also takes the large area of the park into consideration. Thanks to the advantages of IP network technology, it combines convenience and safety, and provides an elegant background music environment and safety guarantee for people’s leisure and entertainment. It is also a great example of how TOA can be applied to large-scale public facilities, parks and outdoor open spaces in the future.”

When the Fuxing Hall was transformed into a field hospital, background music delivered by the TOA

system in this beautiful natural setting created a relaxed atmosphere for patients, while enabling staff to deliver announcements, daily updates, information and scheduled broadcasts in a way that hadn’t been envisaged when designing a flexible, efficient, multifunctional system for the Flower Expo, underlining the extreme flexibility and usefulness of the system.

MLA PROVES ITS CAPABILITY YET AGAIN AT ROCK IN JAPAN

The Covid 19 pandemic has had a profound effect on the music industry in recent years, not least being on the international festival circuit, where many established events were forced to close.

Rock in Japan, the country’s largest festival was no exception, and suffered the same hiatus in 2020 and 2021. However, this year, it was finally ready to make its return and it did so in very different fashion. The five-day event was reborn as an urban style festival in a new location, having moved to the Soga Sports Park in the attractive coastal resort of Chiba from its previous home of Hitachinaka.

However, the change of location had been a major concern for those managing and promoting the shows. For Soga Sports Park is located near residences and in a densely populated shopping area—hardly ideal for holding a loud rock show. Additionally, it was the first time that a festival had taken place here. The potential of noise pollution problems caused huge headaches for the production team.

“We had to adopt a completely different the approach,” stated Shuzo Fujii, president of MSI Japan, the sound production company. “Up until now, we have always focused on how far we could throw our MLA loudspeaker array, but this time we had to think in an opposite direction.”

THE RESULT WAS A MAJOR SUCCESS, NOT ONLY BECAUSE OF THE UNIQUE DISTRIBUTION DESIGN BUT ALSO BECAUSE OF THE CONTROLLABILITY OF MLA SYSTEM. ONCE AGAIN, I WAS ABLE TO APPRECIATE THE WONDERFUL CAPABILITY OF THIS LOUDSPEAKER.

Shuzo Fujii, MSI Japan

With Tomoya Shitakubo, who also acted as system tech, in charge of the design,

they devised a unique solution which had not been adopted previously—importing a number of delay towers and developing a distributed sound system. MSI acknowledge that in the history of Japanese festivals, the distributed sound system approach had not been attempted, and so this became a voyage of discovery for both for the promoters and MSI crews.

“The promoter is our client, and he has specified MLA for the past 10 years,” stated Shuzo Fujii, who also acted as chief engineer for the event. “Everybody had faith that MLA would be able to overcome this difficult problem.”

The two main stages were both equipped with eight MLA per side for the main PA system. These were reinforced by 18 MLX subwoofers in cardioid pattern. The subs were set in two 3 x 3 cabinet stacks—on both sides of the stage—with the middle one in each reversed.

In addition, seven MLA arrays comprising seven elements were set in four locations as the delay towers (with eight delay towers in total).

Generally, delay towers are set symmetrically to provide coverage for both sides. However, these were positioned only for coverage on one wing in order to reduce the spill to the neighbouring residential area. The result was amazing. There was no difference in sound level, starting at the FOH mix position and sufficient power was distributed across the entire venue, meeting the required SPL and quality of sound.

“The result was a major success, not only because of the unique distribution design but also because of the controllability of MLA system. Once again, I was able to appreciate the wonderful capability of this loudspeaker,” Shuzo concluded.

WAVEFRONT PRECISION IN FULL BLOOM AT SHREWSBURY FLOWER FESTIVAL

Visitors attending the plethora of county and horticultural fairs that take place during the UK’s outdoor season, deserve the same quality of audio as hardened music fans revelling at the UK’s premier festivals.

BSB Sound owner Martin Bickley, whose company specialises in providing PA for all manner of outdoor shows, was looking for a fresh approach to deliver first class audio for the annual Shrewsbury Flower Show as the previous design of public address system was no longer suitable due to the mounting bases for the loudspeaker masts becoming unsafe. He therefore approached a long-term associate, Robin Dibble, who also happens to be one of the Martin Audio product support team.

The show is one of the country’s premier events of its kind, attracting top exhibitors from all over the UK to the site on the banks of the Severn. After a site visit to investigate the event and its requirements, Dibble specified two hangs of Martin Audio’s WPL array cabinets to be flown from towers, with a spaced broadside array of SXH subwoofers between. This he knew would provide not only high-octane audio but evenly distributed, site wide coverage.

To supply the equipment, Bickley contacted Bristol based Martin Audio partner, SWG Events, who were pleased to sub-hire their powerful and ground-breaking Wavefront Precision WPL optimised line array. The two towers were also provided by SWG, whose head of audio, Simon Purse, assisted with the set-up.

“We needed to ensure we had consistent quality and intelligibility over the 150m throw distance whilst keeping levels contained on site, with a 74dBA limit at the borders of the event site,” noted Dibble. “The site itself is in a natural bowl and the results of any events in the show ring during the day needed to be broadcast with absolute clarity by the commentators, while in the evening both military and contemporary bands took over the stage, followed by a laser display. This is where the subwoofers—a broadside array of 12 SXH218 (2×18”) enclosures—came into their own.”

The DISPLAY 2 files were prepared by Robin Dibble and loaded into the amps ready for use by Purse, with some tweaks on set-up days. “The main challenge,” Dibble continued, “was getting accurate site information because of its unusual shape, and the fact it was the first time we had worked here. So we undertook terrain mapping with SketchUp, adjusted with on-site surveys during set up.”

Sound was mixed from a desk in the commentary box, set 50 metres behind the speakers, and Robin Dibble, who took responsibility for the overall site design, was more than happy with the outcome. “This event was all about achieving consistency of coverage rather than pushing level. It worked extremely well and sounded fantastic.”

Martin Bickley agreed. “Shrewsbury Flower Show is a favourite event for us at BSB Sound and is bigger than many realise, typically with over 10,000 people sitting on the bank enjoying a wide variety of entertainment from the main show ring.

“The results were a revelation; the improvement in consistency and quality throughout the audience was a real eye opener. All the BSB Sound team were impressed with the results, and we are looking into the possibility of purchasing a WP based system of our own on the back of the equipment’s performance at this event.”

MLA KEEPS RIOT FESTIVAL SITE UNDER TIGHT AUDIO CONTROL

Solotech makes a mighty statement at Victoria Park with premier line array

There can be few production companies more familiar with the challenges of east London’s Victoria Park site than sound specialists Capital Sound (part of the Solotech UK Group).

Often working alongside Loud Sound they have supported many of the music events and festivals at this location for more than a decade. It was here in the summer of 2011, first for Deadmau5 at the LED Festival, followed by other back-to-back events including Field Day, that they proved that even within a densely populated residential area, they could achieve enviable levels within the performance area without disturbing the neighbours.

It was at these events that Capital debuted, and established the unique controllability of Martin Audio’s award-winning MLA technology, and a further propagation test at Hatfield House duly led to its adoption at another challenging site, Hyde Park, for BST, which persists to this day.

But such demands place pressure on their inventory and he adds that they are fortunate to be able to utilise the growing Martin Audio network when it comes to pulling in extra inventory. “Martin Audio also provides great support where we need it and has done a fantastic job staying involved. But as the user network has grown, we have managed to rely less on manufacturer support and more on partner support.”

Once again, for reasons of efficiency, the organisers tweaked the layout of the two main stages (named Riot and Roots), while out around the perimeter the Radical (Stage 3), Rise (Stage 4) and Rebel (Stage 5) areas belonged to Martin Audio.

Between them these stages hosted a number of top acts, including Bleachers, Sunny Day Real Estate and The Academy Is (Stage 3), Portugal the Man, Yellowcard and Ice Cube (Stage 4) and Marky Ramone, GWAR and Real Friends (Stage 5).

Radical and Rise were identically configured with MLA, while the slightly smaller Stage 5 mounted a Martin Audio W8LC.

Having been running Martin Audio systems since the late 90s, Technotrix are familiar with the British manufacturer’s signature sound. And the familiar presence of MLA once again gives Grant Simmon all the reassurance he needs.

But inter-stage sound containment remains a major issue. “We used DISPLAY [Martin Audio’s optimisation control and monitoring software platforms] to its full potential again this year, along with a cardioid subwoofer deployment.

“We use the Hard Avoid as people at the back of the stage will have a hard time if LF energy is booming everywhere. We were able to get good cancellation and rear rejection, and excellent gain on the mics.”

But apart from Chicago’s notorious fast changing climatic conditions, which needs to be factored in, the stages mix up many different genres often requiring different volume levels. Technotrix deploys FOH and monitor techs to supervise, as well as two patch experts. “I work with Joe Mion, our FOH engineer as well as the festival director to come up with presets dependent on the time of day, and produce short, medium and long-throw presets; for example, we coordinate a lot of partitions to draw audiences nearer the stage earlier in the day, using short throw.”

Visiting engineers are provided with a start file, so they don’t have to build up their EQ curve from scratch.

On stages 3 and 4 sound engineers mixed through main hangs comprising 11 MLA and an MLD Downfill box at the base on each flank. The subs comprise six stacks of three high MLX, with the middle box reversed, set in a broadside cardioid configuration. Four MLA Compact enclosures are set across the top of the subwoofer clusters for front fill, enabling a reasonable height for projection.

Delays are unnecessary, “as MLA defaults to 100m throw distance, and that’s where they need to be.”

Technotrix also dipped into their inventory of floor monitors, providing XD300s on Stage 3 and 4, driven by iKON iK42, but supplying the more potent XD500 for stages 1 and 2. Drum fill subs in all instances were provided by the hefty SX218 (2 x 18”) subs.

Over at Stage 5 Technotrix fielded six-a-side W8LC and 12 WSX subs in a broadside array, with XD12s, set on the stage lip, providing front fills. The subs were designed in clusters of three, set in portrait configuration. And although these were non-cardioid the audio techs were able to carry out arc steering where necessary.

Brent Bernhardt is entirely comfortable with the capabilities of Martin Audio’s advanced control tools. “We know what kind or arc delays and cardioid patterns are working,” he says. “We walk the site constantly and we work with techs at FOH to determine if the sound needs to be turned down, or in some instances turned up. It needs to be up at 101-102dB(a) to overcome the sound from other areas, but it probably averages out around 99dB. A couple of dB makes all the difference.”

And the crew needs to remain nimble. “With genres often mixed on these stages, suddenly a hip-hop band will come on with excess low end and we will have to change the preset, do some sub shading or tweak the cardioid setting. Martin Audio’s cardioid preset works really well and I’m rarely disappointed.”

The outcome of this attention to detail was one of the Festival’s strongest showings from an audio perspective, according to Grant Simmon.

And Brent Bernhardt confirmed that several of the visiting sound engineers had also given a resounding thumbs-up. “We had several saying it was the best show they had played all season, and all were extremely receptive to the PA—no-one was unhappy,” he said in conclusion. Of his sound team, he singled out freelance system tech Dani Millon, for her excellent optimisation work on Stage 4.

MARTIN AUDIO ENDS A PERFECT SUMMER FOR WPL AT ALL POINTS EAST

Solotech makes a mighty statement at Victoria Park with premier line array

There can be few production companies more familiar with the challenges of east London’s Victoria Park site than sound specialists Capital Sound (part of the Solotech UK Group).

Often working alongside Loud Sound they have supported many of the music events and festivals at this location for more than a decade. It was here in the summer of 2011, first for Deadmau5 at the LED Festival, followed by other back-to-back events including Field Day, that they proved that even within a densely populated residential area, they could achieve enviable levels within the performance area without disturbing the neighbours.

It was at these events that Capital debuted, and established the unique controllability of Martin Audio’s award-winning MLA technology, and a further propagation test at Hatfield House duly led to its adoption at another challenging site, Hyde Park, for BST, which persists to this day.

Yet proof of concept is continuously evaluated, and this year further modelling was undertaken against another premier brand, before MLA rightly took its familiar place on the East stage in Victoria Park, at AEG Presents’ now consolidated All Points East.

IT SOUNDED GREAT, AND WE COULD ACHIEVE THIS SPL, WITHOUT BREACHING OFFSITE LEVELS.

Martin Connolly, Solotech senior project manager

Solotech senior project manager Martin Connolly confirmed that, under evaluation, the same measurements had been achieved as previously. “It’s good to have scientific data, but then we have proved the point over and over again with MLA.”

This year the coverage pattern was tweaked in accordance with the slight reorientation of the stage away from the sensitive flank. Meanwhile, on the West stage was Martin Audio’s newer Wavefront Precision technology, embodied in the mighty WPL.

The main hangs on East stage comprised 13 MLA and a single MLD (downfill) box on each side per side, with side hangs of nine MLA stage right, and eight on stage left. Frontfills comprised eight Martin Audio XD12, with a castellated cardioid broadside array of 20 MLX subs along the front.

Further back, five delay points were set, populated by a total of 46 MLA Compact, with six MLX subwoofers in a cardioid design on the last two positions. Finally, stage sidefills comprised four SXHF218 subwoofers, and a pair each of Martin Audio TORUS T1215 and T1230 constant curvature boxes.

It was left to the Solotech crew, comprising system tech Dan Fathers and FOH tech Xavier d’Arifat to ensure Gorillaz, Chemical Brothers, Tame Impala, The National, Nick Cave and Disclosure, along with their respective tech crews—were given the best experience possible.

Meanwhile, headlining West Stage—situated further back on the site, and surrounded by trees—Idles enjoyed a very different audio experience, as Martin Connolly explained. “After the huge success of BST at Hyde Park where it was featured for the first time, we took the decision to run WPL [as the main PA] on the West Stage, along with WPC—and the new SXHF218 subs in a castellated cardioid array.”

Here, levels of up to 104dBa were possible, including 103dBa for Fleet Foxes and 102dBa for Caribou. “The implementation of WPL was a huge success,” summarised Connolly. “It sounded great, and we could achieve this SPL, without breaching offsite levels.”

Main hangs comprised 12 WPL per side, while side hangs consisted of 10 WPC (stage right) and 14 stage left, further augmented by eight WPS. The broadside array of subs comprised 11 SXHF218, while the two delay masts each supported 12 WPC.

Monitors on West stage comprised 12 Martin Audio LE1500, four SXHF218 subs and a pair each of TORUS T1215 and T1230. Joseph Pearce was Solotech’s system tech and Jackson Akers, tech at FOH.

As at BST, the company was working alongside experienced production manager Mark Ward (of Proper Productions). Confirming the success of the event, Ward, said “The combination of Solotech’s expertise and Martin Audio’s advanced control technology has proven time and again that challenging sites such as Victoria Park and Hyde Park, once considered almost unworkable, are entirely viable when it comes to staging proper events.”
