Renkus-Heinz Helps Conquer Audio Challenges in Canadian Museum for Human Rights

 Winnipeg, Manitoba – February 2015… With a portfolio that includes high-profile museums, performing arts centers, corporate settings, and high-end residential theaters, Milford, CT-based SH Acoustics has gained a well-earned reputation in the rarefied world of sound design for some of the world’s most challenging acoustical spaces. For the new Canadian Museum for Human Rights in Winnipeg, Manitoba, the combination of open architecture, reflective surfaces, and a plethora of multimedia-based exhibits made the firm the preferred choice as acoustic and audio design consultant.

SH Acoustics President and Principal Consultant Steve Haas was invigorated by the challenges the museum presented. “What makes this building unique is the open nature of the architecture,” he explains. “The walls and ceilings rarely meet, and there are few if any right angles. There are literally no doors in the galleries. Even the glass exhibit walls are unique, with open, overlapping ‘shards’ instead of a flat surface. To achieve focused sound in the exhibits and galleries and, more importantly, to control it, required a lot of specific audio gear, acoustical treatments, and careful planning and calibration.”

Renkus-Heinz loudspeakers and steerable array systems proved to be a key tool in realizing the promise and goals of the museum space. “I have had great success with Renkus-Heinz in similarly challenging spaces, especially their Iconyx arrays,” says Haas. “The pattern control and fidelity they offer are ideal for applications like this, which require working closely with architects, engineers and AV designers to deliver the intended sound without bleeding throughout the exhibit galleries.”

Haas cited the Canadian Museum for Human Rights as among the Company’s more challenging recent projects. While the ten main galleries are spread throughout the building’s seven levels, each floor is acoustically coupled to at least several others, with open architecture, reflective glass walls, and oddly-placed criss-crossing ramps connecting and passing through all the galleries. SH Acoustics worked with Electrosonic, a US-based international AV integration firm, and over a dozen media producers from all around the world, to ensure its sound designs would translate accurately to the museum space.

“We used a lot of different techniques to coordinate between the acoustics and audio,” says Haas. “Some were very localized and focused, while other spaces needed a widespread soundscape. In the mini-theater settings, Renkus-Heinz gear was involved in a big way. We used the TRX and CF Series speakers, some with PN112 subwoofers, as primary front delivery speakers behind the screen, because we’ve come to know the preciseness of their radiation pattern.”

For some of the wider theaters, off-axis response naturally became an issue, again with a Renkus-Heinz solution. On the upper level, the “Canadian Journey” gallery utilizes two IC16-R-II digitally steerable line arrays, augmented by PN Series subwoofers. “The Canadian Journey contains dozens of local media experiences, but comes alive each hour with a sound and light show projected on large screens, plus a powerful presentation with live actors,” explains Haas. “The Iconyx digital beam steering makes it easy to transition between the two programs.”

 The mechanically steerable Iconyx IC7 series also found a unique use in the museum’s primary gallery for the multimedia presentation, “What are Human Rights?” Haas explains the challenge: “The screen and seating area are roughly 90 feet wide, with multiple video projectors. We needed low-level localization of sound to cover that very wide bench in a very precise way.” The solution was to use four IC7-II mechanically steered arrays, aimed from above complemented with compact subwoofers embedded in the bench itself and a series of seven TRX speakers behind the large scrim. This provided full-range, focused sound to listeners, while still localizing back to the images on the screen. Strategies like this also helped to avoid interfering with the building’s ceiling speakers, which are required for paging.

Designed by acclaimed architect Antoine Predock and Exhibit Designer, Ralph Appelbaum, the Canadian Museum for Human Rights opened on September 19, 2014 to outstanding reviews. For SH Acoustics, it was another in a long line of acoustical challenges met and conquered. “It’s quite an ingenious design – one of the most fascinating buildings I’ve ever been in,” says Steve Haas. “With both large theaters and small interactive displays in an open acoustic environment, you really have to play with the laws of physics to make it all work together. But with tools like the Renkus-Heinz speakers we’ve come to rely on, it really came together nicely. Everyone is extremely pleased.”

Renkus-Heinz IC2 a Hidden Gem at University Chapel

 Newport News, VA – February 2015… Christopher Newport University recently took the wraps off its newest addition, the non-denominational Pope Chapel. The 10,000-square-foot building stands at the entrance to the University and includes state-of-the-art audio, video, lighting, and media systems, including a powerful and versatile audio system centered on the digitally steerable IC2 (IC Squared) array from Renkus-Heinz.

Tom Beaudry, Owner and Senior Designer of Chesapeake-based design/build specialists Onyx AudioVisual, worked together with Erik “Ketch” Kelly, audio engineer for CNU’s Ferguson Center for the Arts to design the systems. As Kelly explains, versatility was a key requirement for the new venue’s sound system.

“The chapel is used for meetings and services by various campus religious groups, but also hosts weddings and musical programs, so the system needed to be versatile enough to deliver a wide range of program material,” explains Kelly.

The 350-seat chapel’s stunning Neo-Georgian architecture is beautiful to behold, but notoriously reverberant, making spoken word intelligibility a critical issue, and making it an ideal candidate for a digitally steered array. As Beaudry observes, the IC2 delivered the best of both worlds.

“We needed a high performance, high fidelity, system that could deliver intelligible speech in a highly reverberant space,” explains Beaudry. “The IC2 system gave us the pattern control of a digitally steered array, but with the full range musicality and output power of a point-source array.”

 Just two self-powered IC2-FR cabinets cover the entire room, each hidden behind scrims in two small soffits above and on either side of the stage area. “We basically needed a compact, invisible sound system that was robust and flexible enough to be used for anything, even an occasional rock band,” says Kelly.

In fact, the IC2 system delivered more than enough power, says Beaudry. “We had originally specified two boxes per side, and were a bit apprehensive when we learned that there was only room for one. But we have more than enough volume from just a pair of IC2 cabinets.”

A big test for the system came when the university decided to add a pipe organ to the room. “That was not part of the original design concept for the chapel, and we were a little concerned because of the wide frequency spread of the instrument,” says Kelly. But as Beaudry notes, “the IC2 easily handles the full range and impact of the organ. It really confirmed that we had made the right choice for the room.”

Beaudry concludes, “for a space like Pope Chapel, we had to design a system that delivered great intelligibility as well as the power and performance for a wide range of source material. And it had to have a footprint that was virtually invisible. The Renkus-Heinz IC2 does exactly that – even when you can’t see it.”

Small Church Gets Big Sound with Renkus-Heinz VARIA

 Homestead, FL – February 2015…  Located about 45 minutes south of Miami, Florida, Princeton Church of the Nazarene has survived at least three major hurricanes over the past century. The church’s modest 200-seat sanctuary has a long history of struggling with uneven sound quality and poor intelligibility. As the first stage in a renovation for the building’s upcoming 100-year anniversary, the sanctuary was recently updated with a new sound system centered on Renkus-Heinz VARIA modular point source line array loudspeakers.

The system was specified by Robert Bernecker of Waxahachi, TX-based SEFI Consulting, and installed by Revelation Sound of Miami, FL. Bernecker saw this modest house of worship as an ideal setting for VARIA’s hybrid approach, using just three loudspeakers to provide controlled coverage for the entire sanctuary.

“The old system was just hammering the back wall, creating a lot of slapback, yet it wasn’t covering the front seats because it was aimed so high,” explains Bernecker. “It had very wide dispersion and zero control. VARIA’s modular design enabled me to create a system with the power of a line array, but with the pattern control to cover the room very nicely.”

VARIA’s modular design includes a range of cabinets with configurable horizontal and vertical dispersion patterns. Renkus-Heinz proprietary progressive waveguides enable transitions between two horizontal dispersion angles within a single cabinet. The result is a custom configurable system, with tighter pattern control using fewer cabinets.

“Originally, I looked at this church two years ago, and envisioned it would take about 12 horns and a few clever tricks to get the pattern control the room needed,” Bernecker recalls. “But by the time the church was ready to move forward, Renkus-Heinz had released VARIA, which gave me the tools to do the same job, with better control, using just three boxes and a good DSP system. The timing was perfect.”

The system at Princeton Church of the Nazarene comprises a single array of three VAX101 enclosures, with a different waveguide in each. The bottom speaker sports a 120-degree horizontal guide to enable full coverage of the front rows. The middle box uses a transitional waveguide that goes from 120 degrees to 90, while the top cabinet continues the progression from 90 down to 60 degrees. A legacy subwoofer is flown behind the VARIA system to provide bass extension.

 “By putting those three boxes together in that fashion, you get a seamless array with plenty of output,” explains Bernecker. “The 10-inch drivers couple together in line array fashion, which is perfect for the lows and low mids. Yet when you get to the highs, each of those horns is serving a distinct area, more like a point source. So it’s really a hybrid approach, and exactly what a smaller room like this needs.”

To ensure even coverage, Bernecker used Symetrix DSP to control the output of each speaker. “For the long throws at 60 and 90 degrees, I obviously wanted all three of those drivers firing,” he notes. “But to keep from blasting the front rows, I used FIR filters to get my pattern control by shading off each box at different frequencies. In essence, we created a variable length array that was still totally phase coherent. We were never able to do that before, and I was very, very pleased with the evenness.”

This was the first installation of Renkus-Heinz VARIA for both SEFI Consulting and Revelation Sound, and the benefits were immediately obvious, with fewer loudspeakers providing full-range audio with excellent intelligibility. “It’s the kind of thing we do routinely in a 1500-seat house of worship, using 12-box arrays coupled with some high-end processing,” says Bernecker. “VARIA enabled us to bring those same capabilities to smaller churches, giving them incredible bang for their buck.”

Mike Melcher, President of Revelation Sound, agrees. “ The Renkus-Heinz VARIA system sounds absolutely incredible,” he asserts. “This will be our premiere system for new customer demonstrations.”

As for the worship team and congregation, Bernecker reports that their first experience was revelatory. “When they walked in, their jaws dropped,” he recounts. “They had dealt with poor coverage for so many years, it was amazing to them – to have every corner of the room covered perfectly, and how the PA cuts off right at the platform’s edge. They could not believe how much clearer it sounds.”

RG Jones and Martin Audio MLA Win The War of the Worlds

War of the Worlds - The O2 Arena December 2014

Following a triumphant UK and European arena tour in 2012, Live Nation and SJM Concerts announced the ground-breaking tour of Jeff Wayne’s Musical Version of The War of The Worlds would return for the sixth and final time in late 2014 early 2015, with RG Jones Sound Engineering producing.

‘The New Generation’ as it is now known, played to packed arenas throughout the UK and Northern Europe this winter with the tried and trusted team of Simon Honywill, FOH engineer and Martin Audio’s full catalog of MLA (Multi-cellular Loudspeaker Array) components once again on hand to create a superior soundscape.

War of the Worlds - The O2 Arena December 2014

Conducted by Jeff Wayne, the most ambitious production yet featured Liam Neeson in 3D holography, Jason Donovan as Parson Nathaniel, Westlife’s Brian McFadden as The Sung Thoughts of The Journalist, X Factor 2005 winner Shayne Ward as the Artilleryman, Les Miserables’ Carrie Hope Fletcher as Beth, Parson Nathaniel’s Wife, X Factor 2013’s Joseph Whelan, as The Voice of Humanity, the 36-piece ULLAdubULLA Strings and the 9-piece Black Smoke Band.

The show is mixed live in Surround Sound and features remarkable special effects such as the incredible 3-ton, 35-foot tall Martian Fighting Machine firing real flames into the Arena, a 100 foot wide “animation wall” with two hours of cutting edge CGI, the incineration of a cast member in front of the audience’s eyes, and a ground-breaking levitation effect.

Adding a new dimension in the spectacular finale, HG Wells, author of The War of The Worlds, was brought to life in three riveting scenes within the show – aged 33, 53 and 79 – spanning the end of the 19th century and two subsequent World Wars. Scottish actor Callum O’Neill played HG Wells, best known for his role as ‘Wee Dingwall’ in Disney Pixar’s 2012 summer blockbuster, Brave.

War of the Worlds - The O2 Arena December 2014
Simon Honywill believes this to be the most daring production so far, and was delighted that he once again had MLA under his control. “Frankly, in an ideal world it would be the only system I would ever work with. It’s the most intelligent touring system ever, that has been responsible for the dramatically increased level of performance and coverage consistency, and paints such a neutral canvas that the slightest adjustment I make on the desk delivers exactly what I want for the audience.”

The War of The Worlds has to be one of the most challenging pieces of music to portray accurately in a live setting. The musical elements, consisting of the band, the orchestra, the iconic narration, live acting and singing, playback and surround effects, occupy over 140 input channels, and the audiences rightly expect an unprecedented level of detail. The rest of the production is just as epic, and this makes for a very demanding daily task for the entire crew, working to a very tight schedule with 12 trucks of gear to load in and out. For the sound team, set-up times and system tuning opportunities are very limited, and with any system other than MLA it would have been virtually impossible to get the consistently amazing results across a wide range of venues.

Honywill, arguably one of the most seasoned practitioners of MLA in the world, clearly enjoyed himself with the Liverpool Echo quoting, “Wayne’s music has never sounded more commanding.”

Meyer Sound LEO Goes “Gangnam Style” with Psy in South Korea

psyPsy, a global viral superstar, recently played four sold-out shows at Seoul’s 14,000-capacity Olympic Park Gymnastics Arena. Dubbed “All Night Stand,” the hometown shows were powered by a Meyer Sound LEO® linear large-scale sound reinforcement system.

“The extended headroom and linear output characteristic of LEO is huge with Psy’s music,” says Park Dong Won, the singer’s veteran FOH engineer. “The highs were smooth and natural, even when we pushed the levels, and the dispersion meant uniform coverage for every seat. I’m not just confident in specifying LEO, but also proud to use it.”

The system comprised dual main arrays, each with 15 LEO-M line array loudspeakers flown over two LYON-W wide-coverage line array loudspeakers as down fill. Twenty-four 1100-LFC low-frequency control elements were arranged in a directional array, with seven MILO® line array loudspeakers per side for out fill and two-each LYON-W and MICA® line array loudspeakers for front fill. Onstage foldback was supplied by two side-fill stacks with two 700-HP subwoofers and four MILO loudspeakers each, along with 20 MJF-212A stage monitors. A Galileo® Callisto™ loudspeaker management system with four Galileo Callisto 616 and two Galileo Callisto 616 AES array processors supplied drive and optimization.

“Psy was very happy with the LEO system when he first heard it during rehearsals,” reports Park. “He had been using other large-format systems, but discovered that LEO was the first that could deliver clear high frequencies at extreme levels without hurting your ears.”

The LEO system was supplied by Live MISO and designed by Y Hun Lee, systems tech from Sovico, Meyer Sound’s Korean distributor, in consultation with “dB Dave” Dennison, a veteran international system design and tuning specialist.

Park mixed the shows behind a DiGiCo SD7 digital console and was assisted by second engineer Ko Jong Jin. A DiGiCo SD8 was used as a sidecar for Pro Tools track playback. Wireless audio for Psy and his special guests was via a Shure UR4D system, with Psy singing through a custom silver handheld transmitter equipped with a Shure Beta 58A capsule.

Released in 2012, Psy’s “Gangnam Style” became a worldwide cultural phenomenon with over 2.2 billion views on YouTube. Psy’s popularity in Korea continues unabated as his concert ticket sales, recordings, and video all occupied the number one positions for 2014.

L.O.C. FOH Mixer on Meyer Sound LEO and LYON: “Whatever Sound I Put In is Exactly What Comes Out”

L.O.CDanish hip-hop artist L.O.C. became the latest artist to tour with Meyer Sound LEO-M and LYON™ linear line array loudspeakers. Named the “Rødt Lys Tour” (“Red Light Tour”), the production was mixed by Mads Stærke, one of Scandinavia’s most in-demand FOH engineers.

“With LEO and LYON, I know the system will respond musically, so I just let the voices and the instruments do their thing and use much less EQ,” says Stærke, who has worked with L.O.C. for the past seven years. “This system allows me to mix musically, and not technically.”

The touring system comprised 20 LYON-M main line array loudspeakers, with four LYON-W wide-coverage line array loudspeakers as down fill and four UPA-1P loudspeakers as additional fill. In some of the larger venues, 16 LEO-M line array loudspeakers anchored the main system. Ten 1100-LFC low-frequency control elements were driven by the main mix, while 10 more received a separate feed for extreme low-end effects. Two additional 1100-LFC loudspeakers and four JM-1P arrayable loudspeakers were deployed on stage for side fill, while a Galileo® Callisto™ loudspeaker management system with one Galileo 616 AES and two Galileo Callisto 616 array processors provided system drive and alignment. Risskov–based Victory Tour Production provided the system, with Theis Romme serving as system tech.

According to Stærke, also an experienced mixer of jazz, EDM, rock, and pop, the advantages of mixing on LEO and LYON apply across musical genres. “The first time I mixed on a LYON system was actually a pop concert, and I was blown away by the accuracy and clarity,” he recalls. “Whatever sound I put in is exactly what comes out—the system gives me a very precise and clear feeling of the music. It feels like I can do anything with it. It’s so powerful and physical but at the same time very musical. The 1100-LFCs are also extremely precise in the way they move the air, and are much more powerful than any other low-frequency speaker on the market.”

Stærke mixed the show on a Midas PRO2 digital console, while monitors were mixed on a DiGiCo SD8 digital console. Performers used a Shure Axient digital wireless microphone system with KSM9HS head, in addition to Sennheiser SR 2050 transmitters and EK 2000 beltpack receivers.

L.O.C. has been Denmark’s most popular hip-hop artist for nearly two decades, both as a solo act and a member of the groups Alzheimer Klinikken and B.A.N.G.E.R.S. A two-time Danish Music Award winner, he has been both a coach and a judge on the Danish TV version of “The Voice.”

3G Productions Teams With Martin Audio MLA At Calibash Festival

Calibash StageCalibash Los Angeles, held recently at the Staples Center, was billed as “the leading urban Latin music festival in the world.”

The SRO concert featured a diverse group of acts including headliner Cuban American rapper Pitbull of “Don’t Stop The Party” fame along with Carlos Vives, Tego Calderon, reggaeton artists Wisin and J Alvarez, Don Omar, Becky G, Maluma, 3BallMTY, ChocQuibTown, Plan B, Farruko and Gente de Zona.

3G Productions of Las Vegas and Los Angeles provided a Martin Audio MLA system for the festivities which included 16 MLA and 2 MLD (downfill) a side for the main hangs; 16 MLA Compacts for side hangs; 8 MLA Compacts for the 270º hang and 28 MLX subs in double stacks––24 across the stage and a pair on each side pointed 90º to the audience. The mixing consoles for FOH included two pairs of Yamaha PM5D’s for the festival and an AVID Venue Profile for headliner Pitbull.

“We also used Martin Audio DD12s for the front fills,” points out 3G Systems Engineer Manny Perez. “They were awesome; really smooth, clear and responsive, like the whole system.

“In fact, the whole show went really well and all of the band’s FOH engineers were happy, even ecstatic at some points. It was kind of like playtime for them; they didn’t know what else they could do for their mix, which was a real change of pace.

“They ended up just hanging out, listening to each other’s mix, watching what the other guys were doing. They all really enjoyed the MLA system. They’d all heard about it but many hadn’t mixed on a big PA like that before.”
January 24, 2015

Asked about particular challenges for the event, Manny responds, “Not that much really. It was a regular end stage set up but they sold seating that went all the way around so we ended up using the house PA to supplement the area behind the stage. We’ve been in Staples Center many times, and it gets easier every time we go in there. It was very fluid in terms of the load-in and setup, even when they snapped in the stage before we could set up the subs.”

Concluding, Manny adds, “The MLA rig was great, we had plenty of headroom and there were smiles all round the room. At the level the engineers had it, which was close to 105 or 106dB, they were wondering what else they could do, because instead of struggling at that point, it was perfect. They also loved the sub bass being so powerful and smooth.”

Martin Audio Offers EASE Sound Design Support For MLA

EASE mlm_test_6300_d2_bal
Martin Audio has announced support for installers and sound designers with the provision of specific GLL files for designs using MLA, MLA Compact or MLA Mini in an EASE model.

Andy Davies, head of the Product Support Group for Martin Audio said, “The increasing demand for Multi-cellular technology in an installation environment has driven this development as an initial in-house solution; however, we are also working towards making this a simple addition to future iterations of our free-to-own Display software.”

For the time being, in order for Martin Audio to supply a GLL file all that is required is an EASE ‘packed’ project file of the venue showing the array location points, together with the appropriate Display2 file for the venue. Davies continues, “We can then extract the necessary data from the Display2 file and, via additional software, generate the specific GLL; this will include the inter-cabinet and array tilt angles, together with all the associated filter coefficients generated within Display2 to meet the set objective targets. It will also incorporate the appropriate Case Data for a visual representation of the proposed array within the EASE model.”

The GLL will then be inserted into the EASE model at the predefined location points and the coverage prediction checked to coincide with the Display2 output. The EASE model will then be ‘packed’ and returned to the installer or designer. Should any anomalies in coverage be discovered, or any circumstances arise where it is felt that improvements to the overall performance of the system could be achieved, then this will be advised when returning the EASE project.

EASE mlm_test_6300_ease_bal

All three MLA models have seen success in permanent installs, from nightclubs, such as the Marquee in Sydney Australia, to theaters like Bochum’s Stadionring in Germany, or auditoriums such as George Washington University’s Lisner Auditorium, to houses of worship like Redemption Church in Arizona and IDC Church in Chicago, USA. The success has been driven not just from the musicality of the systems, but their ability to better control SPL profile, smoothness of coverage, and provide ‘Hard Avoid’ on stage or problem surfaces.

Summing up, Davies said, “By providing additional support to installers and sound designers we hope it will be possible for them to win more contracts and to further showcase the benefits of our MLA technology.”

Renkus-Heinz IC Live Solves Intelligibility Issues in Dodge City Cathedral

 Dodge City, KS – January 2015…  Dodge City’s Cathedral of Our Lady of Guadalupe is a stunning architectural achievement that embodies the classic disparity between traditional and contemporary worship. With its soaring ceilings and open, 270-degree seating, this 1400-seat sanctuary creates a wonderfully reverberant sense of musical majesty, but at the expense of the intelligibility needed to deliver the message.

To address these issues in the 12 year-old building, Amos Yost of Montezuma, KS-based Montezuma Sound was contracted to design and install a new sound system. His solution for creating clear intelligibility amid the room’s glorious reverb was centered on the IC Live digitally steerable array system by Renkus-Heinz.

As Yost explains, the room’s circular design and abundance of hard, reflective surfaces presented a number of challenges, and the existing distributed PA’s speakers were aimed almost straight down at the tile floor, creating uncontrolled reflections that exacerbated the room’s ringing 3.5-second reverberation time.

“The organ and choir music sounded pretty good, but voice intelligibility was sorely lacking,” notes Yost. It was clear that a steerable array system would directly address the room’s issues, but because the sanctuary is a circular space, effective deployment would be tricky.

 Montezuma Sound’s solution was to set up two ICL-FR-DUAL columnar arrays mounted on the walls behind the altar area, cross-firing to cover the 270 degree seating spread while preserving audience sightlines. This arrangement created smooth, even coverage from the first row to the last, a throw of 120 feet. With twin IC Live columns of 16 speakers each, there was more than enough beam steering flexibility to cover all seating, even those under the balcony, while avoiding unwanted reflections from the windows, side walls, and balcony facing.

Our Lady of Guadalupe features two Catholic services each Sunday. The traditional service is in English and features pipe organ and choir. The second mass is offered in Spanish and features full musical orchestration. This made it clear that the cathedral’s new loudspeaker system would require the versatility to not only provide the desired improvement in speech intelligibility, but also provide a powerful music experience for the congregation. Yost opted to augment the IC Live system with a pair of IC215S subwoofers, installed out of sight behind a grille with the pipe organ speakers.

“The church is very happy with the Renkus-Heinz system,” reports Yost. “When we brought it in to demo, the IC Live sounded so clear right out of the box, it blew them away. In fact, they didn’t want us to take it back! When we performed the final installation, we barely applied any system EQ at all. The music sounds great for both worship styles, and the spoken word is now clearly understandable. It proved to be the ideal solution.”
