CREAMFIELDS’ CONCEPT STAGE A BIG SUCCESS FOR SOLOTECH AND MARTIN AUDIO WPL

Cinch presents Creamfields Northcelebrated its 25th anniversary in style in the village of Daresbury—its home since 2006. The site in Cheshire again played host to the dance world’s premier brand, and with it a selection of global DJ superstars over August Bank Holiday weekend.

The biggest EDM event in the UK, hosting 250 artists over the four days, it comprised up to 12 stages, two of which were serviced by Capital Sound (a Solotech company) who have a long history of supporting the event, both in the north and south.

Headliners this year included Calvin Harris, David Guetta and Hardwell amongst others, all performing alongside the likes of Becky Hill, Bicep Live, Eric Prydz, Patrick Topping, Pete Tong, Martin Garrix, Jax Jones, Scooter and Armin van Buuren.

All the performances were DJ playback, and as is customary, each of the stages changed name on a daily basis. Working alongside Production Director Ian Greenway of LarMac Live, Solotech were responsible for ‘Stage 3’—a large TFS structure—and the outdoor stage 8 ‘Runway Stage’, which saw the introduction of a new ‘concept stage’.

THE COVERAGE WAS EXCEPTIONAL, FROM THE FRONT TO THE VERY BACK.

Stage 3 began as a Silent Disco as did all opening stages on the Thursday, changing to ‘Catch And Release’ ‘Stmpd Records’ and ‘MK Presents’ on the successive days. The key nights were Saturday when Martin Garrix headlined and on Sunday where MK revved up the audience hosting his own Arena line up.

Solotech fielded 11 MLA elements with an MLD Downfill at the base on both sides of the stage; further front fills were provided by four Martin Audio DD12, while an array of 13 MLX subwoofers in cardioid ran across the front. Set back in the rear of the compound were two delay masts of 10 MLA Compact enclosures, ground stacked on risers. Overseeing this for Solotech was system tech and crew chief, Olly Fallon.

Stage 8 came alive as Paradise on the Friday, transforming into Trick on the Saturday and Solid Grooves on the Sunday. This stage was designed as a unique self-supporting, eight-leg truss structure, from which a WPL PA was flown. The upstage goalposts (left and right) supported WPL, and delays consisted of two hangs of eight WPS, were flown from the last goalposts of the truss structure.

Rayne Ramsden, crew chief and system tech on this stage, reported that as the first time WPL had been used in this context it was a fantastic success. He said he had received a number of compliments from crews and crowds alike. “The coverage was exceptional, from the front to the very back,” he stated, adding that dance fans surged in to extend the area back some 40 metres beyond the FOH position. “Even with that extra capacity WPL catered for the extended throw distance with no trouble at all,” he confirmed.

The complement of speakers that made that possible were hangs of 13 WPL with a further three WPL fills down on each side of the stage upstage from the main PA hangs. These were supported by an additional four DD12 , providing extra front fills, and a broadside array of 13 MLX subwoofers, providing the all-important LF extension.

Solotech senior project manager, Martin Connolly, described the event as an outstanding success, and the experiment with the eight-legged free-standing structure as a revelation.

Ian Greenway added, “We know Solotech well, and their willingness to adapt and overcome at Creamfields is more important than ever as we start to migrate to newer and more unique structures. With two Creamfields festivals a year now, we’re looking forward to further developing the relationship.”

In fact Creamfields marked its 25th year by launching a second edition—Creamfields South, which was staged early June at Hylands Park in Chelmsford and attracted 50,000 dance music fans.

LEA Amps Power Custom Design Solutions For Boutique Hospitality

Hazelwood Laboratories who specializes in creative audio installations and development of custom system has always provided clients with unique, out of the box solutions. When the firm needed quality and flexible technology they looked no further than, LEA Professional.

Let’s dive in!

THE INTEGRATOR

LEA AMPS POWER CUSTOM DESIGN SOLUTIONS FOR BOUTIQUE HOSPITALITY

Founded in 2012 by artist and audio/video integrator Joseph Hazelwood, Hazelwood Laboratories is a design-centric creator, fabricator and installer of purpose-built electronic hardware.

THE INSTALL

LEA AMPS POWER CUSTOM DESIGN SOLUTIONS FOR BOUTIQUE HOSPITALITY

CS354

Prior to discovering LEA Professional amplifier technology, Hazelwood was frustrated with other manufacturers, whose technology limited him to playing only within their proprietary ecosystems.

“For my installations, I want best-in-class products for each system, but I also want that system to be able to be controlled and monitored autonomously,” said Hazelwood. “Many of my projects include tactile control interfaces that inspire interactivity, and with the LEA Open API platform, their Connect Series amplifiers can integrate with almost any AV system, giving me the flexibility that I need.”

LEA Professional’s Open API gives system integrators access to a diverse range of plug-ins, as well as expanded local area network amplifier control capabilities using LEA Professional’s web user interface and cloud platform. This ensures that LEA products will play well with other systems so integrators can depend on LEA for any installation requirements. For Hazelwood, this means that with the help of software developer Caleb Szalacinski, he can build custom controllers that are designed both physically and digitally to work with LEA amps.

“While the AV market is increasingly focused on solutions for touch-panel control, tangible hardware controllers seem to be phasing out,” commented Hazelwood. “I wanted to be able to provide my clients with simple, analog-like controls that utilize the benefit of smart technology and of course, look beautiful. I decided to develop my own, and LEA made this possible for me with their open API. I currently have them working in a handful of locations, and plan to eventually make a version of it available for other integrators.”

For Hazelwood, his switch to LEA Professional wasn’t only due to their flexibility but also the accessibility of the amplifiers. At a time when supply chain issues are a battle for other manufacturers, LEA Professional has been able to provide amplifier solutions when he needed them, even on projects with tight timelines. 

For one large installation at a bowling alley in Nashville called Eastside Bowl, Hazelwood had to switch out all his planned equipment for new manufacturers at the last minute due to inventory issues. That’s when he found the magic of LEA’s Connect Series amplifiers, with its seamless design, IoT technology and user-friendly interface. It wasn’t long before LEA became Hazelwood’s go-to amplifier solution. 

“Ordinarily, our controller will be configured to adjust music zones independently, but in this case as there was only one zone of music and the speakers needed to be tri-amped, we programmed the controller to adjust 3 channels of the amp simultaneously, utilizing the LEA’s DSP crossovers.”

THE CONCLUSION

LEA AMPS POWER CUSTOM DESIGN SOLUTIONS FOR BOUTIQUE HOSPITALITY

With many AV manufacturers having inventory issues and ultimately not having products available, Hazelwood Laboratories discovered LEA Professional and the rest is history.

“I have every LEA install in my cloud platform, allowing me to help clients no matter where I am,” commented Hazelwood. “I set up Hazelwood Labs to challenge the typical assumption regarding the role of technology in our lives and I want to work with manufactures who do the same. This is just one of the many reasons why I will continue to provide LEA technology to my clients.”

We would like to thank Hazelwood Laboratories for choosing our amps for these killer installations and we hope that the audio systems will continue to deliver reliable audio for the crowd at The Daily and Barista Parlor for years to come.

SWG EVENTS SPECIFY MLA COMPACT FOR SPECTACULAR HAMPTON COURT PALACE FESTIVAL

Having routinely specified Martin Audio’s MLA Compact PA for festival shows where sensitive offsite noise has been an issue—along with the smaller MLA Mini on corporate events—Bristol based SWG Events has continued its long tradition.

Best known for servicing a number of stages at Glastonbury with Martin Audio solutions the production company recently provided sound reinforcement for the second year to the Hampton Court Palace Festival, having worked for the production company that runs HCPF on other shows.

In addition to the single large stage, which featured two main hangs of eight MLA Compact and six MLX, they also provided BlacklineX on a small bandstand in the East Front public picnic area prior to the show.

This year’s all-star line-up included UB40, Elbow, George Benson, Jack Savoretti, McFly, Kacey Musgraves, The Human League, Michael Ball & Alfie Boe and Crowded House. To provide even coverage for audiences up to 3,200-capacity SWG Events supplemented the two main MLA Compact hangs with DD12s for centre and left/right outfills, with eight WPM for front fills and six Blackline X8 for balcony fills. A monitor package in the shape of 16 of their new XE500 was powered by Martin Audio’s iKON iK42 amplifiers.

Aside from the quality of the music, the orientation of the stage—enabling the Palace to provide a spectacular backdrop—was the icing on the cake, as SWG Event Technology Specialist Ian Williams explained. “The idea is to create the illusion that the audience felt they were inside the palace rather than just in front of it. We illuminated it and handed control over to the lighting designers so it could be used as a spectacular backdrop.”

With Williams himself project managing, leading a team comprising Matt Pope, Ryan Bass and Kieran Jordan, the shows functioned like clockwork. Engineers simply plugged consoles into a pre-time aligned, pre-optimised system, and were provided digital inputs for left, right, sub and fill. “Our system technicians then worked to keep the optimisation as current as possible, working with the engineers to find ideal times within their sets to load in new profiles to the rig”, explained Williams.

SWG’s long successful tradition with Martin Audio equipment, now enters its next stage with their recent purchase of WPL. Williams commented, “We’ve already done a number of shows with our new system and we have received some great comments from engineers that have used it.”

MARTIN AUDIO AND HENLEY FESTIVAL CELEBRATE THE ESSENCE OF AN ENGLISH SUMMER

If there is a single festival that defines the English summer, it has to be Henley, which this year celebrated its 40th anniversary with an eclectic mix of music, comedy, art and grade A fun.

Production managed by John Harris, Henley is a festival unlike any other, with the main stage placed in the River Thames, backed by a fleet of boats of all shapes and sizes. The site features a variety of other venues ranging from intimate comedy to cabaret and dance bands.

RG Jones has been providing audio at Henley since 1983—most of it based around Martin Audio PA—and in a relationship surviving that long, the level of trust and commitment is obviously at its highest. Over the years, the style of the event has changed somewhat from the original, fully classical programme to what is now a much more commercial line-up, but with no less determination to deliver an unforgettable experience. This year’s artists (on the main Floating Stage) were as diverse as Sir Tom Jones, Craig David, Katherine Jenkins, Jack Savoretti, The Script and Pete Tong with the Ibiza Classics Orchestra.

The Floating Stage sound system was manned by the experienced Mark Edwards, using an established design by Simon Honywill. The site is very unusual as it is around three times wider than it is deep, and three arrays each side of the stage structure are required to deliver the requisite coverage; the outer arrays feature nine deep hangs of Martin Audio’s MLA Compact, the forward facing comprise seven deep MLA Compact, and the inner coverage this time was provided by four deep Martin Audio Wavefront Precision Mini (WPM), plus some W8LMD frontfills. “It’s a tricky system to get right,” says Honywill, “as some seats are extremely close to the stage. But years of working on this site go a long way to guaranteeing a first-class audience experience.”

Elsewhere, top comedians were doing their very best to keep everyone laughing in roasting temperatures in The Comedy Club – Andy Parsons, Milton Jones, Maisie Adam and Russell Kane were among the fantastic line up. For RG Jones, The Comedy Club was operated by Sam Liddiard and featured a Martin Audio W8LM/WLX system.

Rosie Tarrant could be found in the Bedouin Bar with a Martin Audio DD12/SXC118 system for a varied mix of world and folk music, and in the Jazz Tent Olly Wickes was tasked with a stream of different acts—handled more than capably by an MLA Mini system.Finally Dan Langridge was anchored in The Riverside Restaurant, mixing the resident dance band on a W8LM/WLX system.

A highlight of this year was the appearance of Boney M in the Big Top.With a fantastic 9-piece band and a raft of backing singers supporting original member Liz Mitchell, they smashed through their massive list of enormous hits to the rapturous delight of a crowd of very up-for-it festival goers.Mixed by Simon Honywill on his first serious Martin Audio TORUS adventure, the sound engineer stated, “the result was one of those one-off joyous things which make you realise why you still do this for a living.” Complete with stage invasion, this extravaganza was a huge success.

Another big success was Honywill’s partnership with LIPA student Sheridan Burns, who came under his tutelage as part of Henley Festival’s new RISE programme. The Festival was set up in 1982 as a charity, its mission being to stage a music and arts festival for the local community. To coincide with its 40th anniversary, they set up RISE to support emerging talent, both in front and behind the spotlight—and Burns was selected by RG Jones to fulfil their RISE quota.

As for TORUS, speaking of his first experience with the system, Simon Honywill stated, “This is a great product; it has great flexibility while maintaining the musical, signature Martin Audio sound that I love so much.

“We had to redeploy the system into a 270° DJ system after Boney M finished … and it totally rocked!”

John Harris also added his own plaudits, both on TORUS and the sound set-up in general: “Henley Festival is proud of its long association with RG Jones and is excited to see and hear the developments in technology that they introduce to our stages.”

Sonance & James Loudspeaker Case Study

Read the case study: https://www.savinc.net/blog/immersive…

Our job is to enrich our client’s lives with technology yet make it so seamless it’s like we’re not even there. To respect the environment, the design, the overall aesthetics, becoming one with the space, just as the wood and steel, the stone and glass.

The various smart home technologies that we integrated at this beautiful home — from distributed audio, TV displays, and a custom theater, to integration into the lighting control and window treatments, even electronic tinting glass — all had to be under one interface that was controlled intuitively and smoothly.

We make it a goal it to compliment the vision of designers and architects, and what they are wanting to achieve, so when it came to integrating an immersive audio experience here, we chose select products from Sonance & James Loudspeaker; small aperture speakers, discreet subwoofers that can be concealed in the floor, ceiling and wall, without having large grills that just draw your eyes to them. Everything simply needed to be clean, discreet and design-centric. That was our solution.

HIGH-QUALITY COMMERCIAL AUDIO SYSTEMS MAKE GOOD BUSINESS SENSE

Background music systems have been shown to have a huge influence on people in just about every situation. However, an area that has been overlooked is the effect that the quality of the music has on human behaviour.

Research has highlighted the way that music can affect consumer habits in a retail environment, employee focus in a workplace and relaxation in a hospitality setting. The first studies into the effects of music on shoppers were published more than 30 years ago and these results have been confirmed and refined time and again since then. Findings by PPS PRL[1] showed that two-thirds of UK adults say that the type of music a shop or business plays influences what they buy. The same survey also found that classical music encourages restaurant diners to order expensive items on the menu and that more than two-thirds admit to leaving a venue after realising that no songs were playing.

Further research, published by JAMA Network [2], notes the implications that music can have in other hospitality settings, such as hotels and spas. This research shows that music can make a positive change in health-related quality of life, which highlights the important role that a commercial audio system plays in therapeutic settings such as spas.

A slightly more contested area is the use of audio in the workplace. This is a subject that has seen a large amount of research, with results that have often been contradictory. Some papers have found that listening to music with lyrics while reading or working can decrease concentration or cognitive performance (Shih et al., 2012 [3];Liu et al., 2021 [4]). On the other hand, a number of studies have shown oppositely that natural-occurring sounds such as white noise, or highly composed sound such as classical music, can be beneficial for increasing focus and can even improve learning outcomes (Davies, 2000 [5];Chou, 2010 [6];Angwin et al., 2017 [7];Gao et al., 2020 [8]).

Recently published research [9] seems to back both of these findings. Amongst its conclusions, the study states: “We found that while performing a self-paced task for a long period of time (such as working), personalised soundscapes increased focus the most relative to silence. Curated playlists of pre-recorded songs by Apple and Spotify also increased focus during specific time intervals, especially for the youngest audience demographic.” Looking more specifically at the effects of different types of audio, the study concluded: “We found that based on our model, engineered soundscapes and classical music are the best for increasing focus, while pop and hip-hop music are the worst.”

It’s clear then that the type of music you play over a commercial audio system will influence your audience, and that crafting the right playlist can have positive results for your business. However, there is one element that none of these studies consider, the quality of the audio your audience hears over the background music system.

There has been less research in this area, and the majority is focused on the quality of audio over consumer equipment. However, there are some useful parallels that we can take from this research and apply it to people listening to background music in over commercial audio systems.

One of the issues with studying this area is that music is very subjective, and different people can have vastly different opinions on the same piece. To overcome subjective issues such as this, researchers use Quality of Experience (QoE) as a way that allows participants to report and rate experiences in a way that can be quantitatively analysed.

The QoE methodology has been further refined with a standard measure just for audio – Overall Listening Experience (OLE). First defined in 2013 [10], the term is used to describe the degree of enjoyment whilst listening to audio. OLE and QoE are comparable in the sense that they both try to take into account all possible factors that may influence enjoyment. These elements could include technical areas such as the sound system, human factors [11] such as mood, and context influence factors such as the listening environment.

By taking all of these factors into account, OLE [12] can be used to see if what effect technical factors have in real-world environments. One of the interesting elements of this is the role that audio quality [10] plays in OLE. Research has shown that the lower the audio quality, the lower people rate their Overall Listening Experience.

There is plenty of evidence that links QoE and improved business performance, particularly in the retail space [13]. In addition to this, background music is cited [14] as one of the main factors that helps to define the QoE in retail.

With this in mind, it is logical that retailers and hospitality venues should also be looking at the quality of their background music systems as part of a wider strategy to enhance customer experiences. With research linking QoE with business performance and the parallel measure for QoE in audio, OLE, showing that higher quality audio leads to a better experience, it follows that investing in a high-quality commercial audio system will be one way to help the overall business performance.

It is widely understood that audio performance is only as good as the weakest link in the signal chain. This would suggest that to see the full benefit in OLE and QoE, sensible investment should be made throughout the signal chain. This starts with a high-quality source that plays music at the maximum possible bandwidth and ends with professional loudspeakers, such as Martin Audio’s ADORN family.

The award-winning ADORN series of on-wall and ceiling loudspeakers bring class-leading performance, reliability and cost competitiveness to a wide range of commercial sound installations — from retail outlets, bars and restaurants to corporate offices. They have been created with audio quality as a top priority and as such can help businesses improve their OLE.

Summing up, Dom Harter, Martin Audio Managing Director, remarked: “Background music systems have not always been at the top of the priority list with retail, hospitality or commercial installations. However, the overall pattern of the research points towards this being a mistake. Making sensible investment decisions in your commercial audio system will help improve the overall listening experience for your audience. This, in turn, will help you to see the full benefits that music can bring to your premises, uniting your patrons. And with ADORN in plentiful supply, you don’t have to be waiting ages to make that change.”

LEA Amps Power Performing Arts Theater : Alfa Theater

Alfa Theater in Pilsen, Czech Republic is a very well known performing arts theatre that specializes in the artform of puppeteering. When they chose to upgrade, they needed an audio amplification system that was flexible, powerful, and shipped on time to accommodate their busy schedule. They chose LEA Professional.

Let’s dive in!

THE INSTALL

LEA AMPS POWER PERFORMING ARTS THEATER : ALFA THEATER

AudioMaster CZ initially received a call from the theater’s sound engineer explaining that they were having trouble with their system and needed them to work on a complete new system design. The team then worked with Jan Zvánovec, from Audio Kropik, the largest seller of AV equipment in the South Bohemia region, to bring the design to life.

“The theater’s sound engineer was having big issues with their existing system,” said Jan Zvánovec, Project Manager, Audio Kropik. “We met him on site and discovered that they had speakers that were not working and older amplifiers that were deteriorating and beyond repair — the system had simply reached its end of life.

The team began searching for system components to fit the theater’s requirements and limited budget. A critical specification was to find high-quality, multi-channel, audio-network-ready amplifiers that were affordable but could also deliver the power needed for the theater.

“I had not used LEA amps before, but they seemed to have all the features we were looking for, at a good price, and they were available,” said Zvánovec. “The amp’s cloud technology, built-in DSP, and the preset features were also very interesting; I wanted to see what these amps could do.”

The team upgraded the theater system with a set of three Dante Connect Series amplifiers. Two LEA CS354D, 4-channel amplifiers are used to power the upper and lower, left, right, and center main speakers, and an LEA CS704D 4-channel amplifier is used to power the system’s subwoofers. The new system comprises a mix of nine JBL AE Compact Series loudspeakers. A Yamaha DM2000 digital mixing console, equipped with a Dante network card, communicates directly with the LEA amplifiers via the Dante audio network protocol.

“The amps’ built-in Dante technology made for an extremely simple connection between the mixing room and technical room; everything worked on the first connection, and we have a lot of flexibility for easy, future upgrades,” said Zvánovec. “And there is also no need for external speaker processors because everything is managed by the DSP that’s built into the LEA amps. These features alone saved the client a lot of money and time.”

Using professional audio amplifiers with built-in DSP has become the standard practice for many AV system installers. DSP-powered equipment can do more with less, and therefore installers don’t need to buy, install, or maintain dedicated DSP equipment. Integrated DSP frees up critical rack space and reduces system weight. All the input routing, room tuning, speaker tuning, and limiting are built into the amplifier, so equipment racks are smaller, lighter, and cleaner.

“All the connectors and features of the LEA amplifiers are very logically arranged and well-engineered; the manufacturer thought of everything from the installer point of view,” said Zvánovec. “Setting up the amplifiers with a web browser is great, and we created several presets and stored them in the amps so the client can easily change the settings. Finally, no complicated installation and setup of applications; it was all very quick and easy.”

THE CONCLUSION

LEA AMPS POWER PERFORMING ARTS THEATER : ALFA THEATER

With many AV manufacturers having supply chain issues and ultimately not having products available, Alfa Theater realized thy only had a small window to finish this project to maintain their busy show schedule uninterrupted.

“Upon first hearing the new system, the client was extremely impressed in that the system sounded so much clearer and better than they had expected; this is thanks not only to the new speakers but also thanks to the powerful, natural sound of the LEA amplifiers,” added Zvánovec.  “I’m glad we had this opportunity to learn about and try the LEA amps; we’re definitely adding LEA to our list as a preferred amp supplier for future projects.”

We would like to thank both Audio Master CZ and Audio Kropik for choosing our amps for this killer installation and we hope that the audio systems will continue to deliver reliable audio for the audience at the Alfa Theater for years to come.

Onehunga High School Case Study

Onehunga High School was established in 1959 on its Pleasant Street site, situated in one of Auckland’s oldest suburbs overlooking the Manukau Harbour. Many families have long histories in the area and have many second or third-generation students. This gives the school a strong sense of tradition and
continuity. In addition, Onehunga High School is committed to providing lifelong learning for the community. As the college looks forward to equipping pupils for life in the 21st century, they require transformative audio, visual and control system updates.

An audio solution for two new state of the art teaching blocks was required. The first, a two basketball court gymnasium with exercise room, locker rooms and teaching spaces. And the second a new technical block catering to the sciences, woodwork, metalwork, art and two commercial-grade kitchens. An atrium space in the technical block also hosts school functions including catered meals where guests can be seated at tables and served directly from the kitchens.

In teaching areas with suspended ceilings, HH Electronics TNi-C4 ceiling speakers were used to provide quality sound while offering a budget-friendly solution. The TNi-C4 is a 4” coaxial speaker with a fully enclosed backcan with ported enclosure extending the low- frequency response over that of a non-backcan version.

onehunga 2
onehunga 3

To maintain audio continuity, the TNi-W4 surface-mount version of the speaker was used in areas where there was no ceiling and the services exposed. The two-piece mounting bracket ensured quick and simple installation.

ITL Technologies, a company with more than 25 years’ experience in delivering quality data and networked solutions won the AV contract, and this experience would enable Onehunga High School to deliver a top- notch learning environment for students and guests.
