LOS ANGELES, California – HARMAN’s JBL loudspeakers were once again put to use at Sunday’s 56th Annual GRAMMY® Awards, with JBL VERTEC® line arrays comprising the live sound reinforcement system at the STAPLES Center and a JBL LSR6300 Series 5.1 surround sound studio monitor system used in the Television Committee Room.

The annual GRAMMY Awards telecast, known as Music’s Biggest Night®, is presented by The Recording Academy® to honor outstanding achievements in the production and performance of recorded music. The GRAMMY Awards were broadcast live in HDTV and 5.1 surround sound on the CBS Television Network. More 28.5 million viewers watched this year’s Awards telecast.
This year’s Awards were hosted by LL Cool J and featured performances by Paul McCartney and Ringo Starr, Madonna, Beyonce, Jay-Z, Bruno Mars, Katy Perry and more. Macklemore and Ryan Lewis earned Best New Artist, Lorde won Song of the Year for “Royals,” while Daft Punk won Album of the Year for Get Lucky, plus two other GRAMMY Awards.

In addition, HARMAN’s Lexicon earned a Technical GRAMMY Award, which is presented to individuals and companies that have made contributions of outstanding technical significance to the recording field.

ATK Audiotek provided the main PA system for the Awards ceremony, which featured four arrays each containing 12 VERTEC VT4889 fullsize line array elements, plus two arrays of six VT4880A fullsize arrayable subwoofers each. An additional 12 VRX932 Constant Curvature loudspeakers were used for front fill.

The STAPLES Center also features a permanent JBL VERTEC line array system, which ATK Audiotek also utilized. The STAPLES Center system features eight arrays each containing between 11 and 13 JBL VT4889DP-DA powered line array elements, plus two fill clusters each containing four VT4889DP-DA elements, which are specially positioned to cover the end seating areas. The system also features four subwoofer arrays, each containing six VT4880A fullsize arrayable subwoofers.

In the Television Committee Room, Michael Abbott, Audio Director for the GRAMMY Awards, along with Recording Academy executives, relied on five JBL LSR6328P studio monitors and two LSR6312SP subwoofers to listen to the mix of the show in real time. “Attention to detail is always essential for the GRAMMY telecasts, and this year’s Awards were no different,” Abbott said. “Thanks to the LSR6300’s accuracy and RMC Technology, we were able to hear every nuance of the performances, and the 6300’s gave us exactly what we needed.”

ATK Audiotek Rocks Halftime Show at Super Bowl XLVIII with HARMAN’s JBL VERTEC® Line Arrays

EAST RUTHERFORD, New Jersey – For the 17th straight year, ATK Audiotek provided audio services for the National Football League’s championship game, Super Bowl XLVIII, the first ever in an outdoor cold-weather stadium. ATK Audiotek deployed its custom-designed, cart-based audio system for the game’s prestigious halftime show, held at MetLife Stadium in East Rutherford, New Jersey. Once again, ATK Audiotek outfitted their system with HARMAN’s JBL VERTEC® line array loudspeakers.

In a battle between the league’s top-ranked offense and defense, Super Bowl XLVIII, broadcast via FOX, reached an estimated 112 million viewers. This year’s Halftime show featured popular pop-singer Bruno Mars, with a special guest performance by the Red Hot Chili Peppers. The Post-Game Show featured the presentation of the Lombardi Trophy to this year’s NFL champion Seattle Seahawks.

For the event, ATK Audiotek deployed 16 of its custom-designed field carts, which allow for easy transport and setup of the JBL VERTEC loudspeakers on and off the field. The system featured 14 carts equipped with four boxes of VT4889 line array elements (56 total), two carts with five boxes of 4889’s (10 total), and each cart was also equipped with two VT4880A fullsize arrayable subwoofers (36 total). Additionally, ATK Audiotek mounted eight VRX932 Constant Curvature loudspeakers on the back of several carts for field fold back, deployed four VT4886 loudspeakers on two popup stands for coverage of the seats behind the stage, and used four more 4886’s for front fill.

“We have come to rely on the consistent performance and sonic capabilities of JBL’s VERTEC line arrays for our systems at the Super Bowl events each year,” commented Kirk Powell, Engineer in Charge for ATK Audiotek. “The Super Bowl is always the most-viewed television event of the year and when you add in the live-broadcast aspect you need to have a system that delivers high quality results with no failures. JBL’s gear has more than met that requirement and that’s why we continue to go back to the VERTEC’s every year.”

DETROIT AUTO SHOWS BENEFIT FROM DANLEY SOUND LABS SPEAKERS AT THE NEW GRAND RIVERVIEW BALLROOM AT COBO CENTER

DETROIT, MICHIGAN – FEBRUARY 2014: The roots of the North American International Auto Show, which is held annually in Detroit, Michigan, go back to 1907 when it was strictly a regional venue for America’s nascent auto manufacturers to parade their latest inventions. Flash forward over a century and the event has become one of the largest auto shows in the world, attracting press and enthusiasts from around the globe to the North American auto-making capital, and bringing an approximate $500 million annual boost to the local economy. As attendance numbers continue to grow, Cobo Center, which hosts the event, recently renovated the underused 12,000-seat Cobo Arena to convert it into a ballroom better suited to the show. Danley Sound Labs SM-60F full-range loudspeakers, supported by Danley TH-115 subwoofers, fire down from the new ballroom’s fifty-foot ceilings to support high-energy auto show productions, along with other events that the new space, renamed Grand Riverview Ballroom at Cobo Center, will host throughout the year.

“The old Cobo Arena was not used very often,” explained Tim Hamilton, A/V designer with Acoustics By Design (Grand Rapids, Michigan) and the lead A/V consultant on the Cobo project. “They gutted it completely, down to the structure, and put in a new floor. The upper half is the new Grand Riverview Ballroom, and it is aesthetically gorgeous, a far cry from the rough arena that went so underused. The Grand Riverview Ballroom is a premium spot, and I suspect that all of the manufacturers will be clambering to rent it, rather than being stuck on the concrete floors of the main exhibit hall. I gave the system enough oomph so that they could easily cover any event short of a full-blown concert.”

The inputs to the system include a collection of AKG wireless microphones together with numerous floor boxes and wall panels. All of the inputs feed a Biamp AudiaFlex signal processing system. Touch panels positioned at strategic locations throughout the hall run Biamp’s daVinci control system software, which allows input selection and volume control. Outputs from the processing system feed Biamp amplifiers that power twenty full-range Danley SM-60F loudspeakers and Crown iTech series amplifiers that power the four Danley TH-115 subwoofers. Each loudspeaker and subwoofer has its own amplifier channel. Preset selection allows users to engage all the loudspeakers and subwoofers as one unit for full-floor events, to split the room in half for situations in which a retractable wall is in place, or to mute the loudspeakers at one end of the hall for events where a stage is in place.

“There weren’t a lot of loudspeaker and subwoofer solutions that would meet all of the particular needs of the Grand Riverview Ballroom,” said Hamilton. “First, they would be fifty feet in the air, and most traditional ceiling speakers would be significantly under-gunned. Second, the beautiful, decorative ceiling had only a limited number of rigging points, and yet we still had to satisfy the need to divide or mute speakers according to the presets. Third, we needed great fidelity and power on a budget. The Danley SM-60F had the right 60×60 beam width to hit the floor correctly, and it has the Danley sound and efficiency at a great price point. Moreover, it is a relatively small box, which satisfied the requirements for the rigging points. All in all, we used the Danley loudspeakers and subwoofers to cover a large space with a distributed system that focuses sound on the floor and minimizes reflections off the ceiling and walls.”

ABOUT DANLEY SOUND LABS Danley Sound Labs is the exclusive home of Tom Danley, one of the most innovative loudspeaker designers in the industry today and recognized worldwide as a pioneer for “outside the box” thinking in professional audio technology. www.danleysoundlabs.com

Landmark Oakland Church Gets VARIA

Oakland, CA – February 2014… Bishop Carl Smith is on a mission, and he’s unapologetic. The members of New Birth Church are encouraged not only to attend church, but to become the church by actively working to improve the quality of the lives of those they touch.

Housed in a mid-19th century Catholic Cathedral, New Birth’s 500-seat sanctuary was an acoustically challenged environment when Concord, CA-based Premier Media Integration, Inc., was brought in to design and install new audio, video, and lighting systems and acoustical treatment. Graham Cooper, President of PMI, contacted Rocky Giannetta, Principal of Layer 8 Inc., to assess the room’s acoustics and assist with systems design.

With Giannetta’s acoustical measurements documenting a reverb time of 3.8 seconds, Layer 8 created an EASE model and designed acoustical treatment and loudspeaker system that PMI would install. While the acoustical treatment reduced reverb to around 1.6 seconds, the environment was still challenging enough to demand an audio system that could keep reflections to a minimum.

“The church has beautiful stained glass throughout the structure,” adds Graham Cooper “Our job was to find places to put the panels that would be aesthetically and architecturally acceptable. Padded chairs, carpet, and, of course, people, also help.”

With reverb down to an almost reasonable level, Giannetta specified the new VARIA line array system from Renkus-Heinz. “We knew that despite our best efforts, the room was not going to be acoustically ideal, and we needed to maximize control of the energy,” he explains. “Typical line arrays would only provide the right directivity in one plane. The client wanted a line array system that would provide the output and headroom for the sound they create, and VARIA fit the bill perfectly.”

The system is comprised of six VARIA VAX101 cabinets per side, with three 7-degree boxes on top and three 15-degree boxes underneath. “With the VARIA’s variable pattern control, we were able to configure coverage from 60 degrees on top to 120 degrees on the bottom,” says Giannetta. Two VAX115S subwoofers per side, along with four DRS18-2 subs on the floor, provide low end reinforcement. The system is powered by Lab.gruppen amplification.

“We’ve been using Renkus-Heinz products on a number of projects, and the clients have always been happy with the results,” says Cooper. “The VARIA system does a great job of focusing the sound on the congregation and keeping it off the walls and reflective surfaces, and the speakers integrate nicely with the room’s architecture. Bishop Smith was emphatic about maintaining the building’s aesthetics, and the VARIA system looks great.”

Giannetta agrees, “the VARIA system was an ideal choice for this project.”

Landmark Building Converts to Mattorosso Restaurant & Live Bar, Sporting HARMAN’s JBL Professional Loudspeakers and a Soundcraft Digital Console

MONTEBELLUNA, Italy – A landmark industrial building in the quiet Italian town of Montebelluna (TV), previously used as a tobacco drying plant, has been lovingly converted into the Mattorosso KMØ Restaurant & Live Bar by Spolverato Umberto and Bressan Lorella, owners of the architecturally superb (and historically significant) edifice. The building also incorporates one of Italy’s biggest MI shops, Esse Music Store.

The conversion has been implemented with the help of a technical infrastructure masterminded by HARMAN Professional distributors, Leading Technologies, and featuring many of the corporation’s premier brands.

Venue managers Manuel and Claudio recall that when they first visited the site at the end of 2011 the brickwork was scored by lime and black carbon; but they say that thereafter “the building’s owners spared no effort or commitment in reconditioning the building and making it fit for purpose.”

Leading Technologies soon became involved in the project and put together an industry-standard sound reinforcement specification within the budget for the 300-capacity venue. Consultant, Paolo Michelini, discussed the design in conjunction with Leading Technologies’ engineers and the building was divided into two indoor zones and one external, ensuring that the sound generated in the live room could also be distributed evenly outdoors.

“The concept was straightforward,” says Leading Technologies’ product specialist, Marco Roveri. “We looked at the project and listened to the owners’ ideas before making our recommendations.”

At the main industrial entrance they have suspended four JBL Control 67P/T pendant loudspeakers from the pitched corrugated roof; these incorporate a large enclosure and high-power 6.5” transducer for extended bass and high-fidelity performance, while the large RBI Radiation Boundary Integrator™ provides outstanding pattern control, which can allow fewer speakers to cover a venue.

In the main live room Leading Technologies specified four JBL VRX932LAP powered, compact 12″ two-way line-array elements, flown two per side, and four ground-stacked VRX918SP bass reflex subs, recessed back into the stage. PRX612 self-powered 12″, two-way speakers and PRX415 15” two-way speaker are used for stage monitoring (with two of the latter deployed for drum fills).

Sound engineers also enjoy the presence of a Soundcraft house desk. Leading Technologies recommended the popular Soundcraft Si Expression 2 console, featuring 24 recallable mic pre amps, and MADI optical card expansion, with I/O capacity extended via a Compact Stagebox (32/16).

All the sound is under the management of a dbx DriveRack 260 although Marco Roveri confirms that future plans are for the sound to be routed to a recording studio in another part of the building. To complete the roster of HARMAN Professional brands on display AKG K 240 MKII Professional Studio headphones have been provided for the sound engineers.

Summing up, Roveri says, “Many companies competed for this contract as they wanted to work in that prestigious building, but the owners chose Leading Technologies for the brands they represent and the back-up they knew they would get. They are extremely happy with the result … as were we, when we heard the system fired up on the opening night.”

HARMAN’s Crown DCi Series Amplifiers and JBL ScreenArray Loudspeakers Highlight Germany’s Haus Zoar Dolby Atmos™ Movie Theater

MÖNCHENGLADBACH, Germany — Located in North Rhine-Westphalia, Germany, Mönchengladbach has a history that goes back to the 10th century—but the city’s newly completed movie theater boasts up-to-the-second technology. Haus Zoar is Germany’s first cinema to feature a Dolby Atmos™ Connect interface with HARMAN’s Crown DCi Series network amplifiers. The cinema has also deployed JBL ScreenArray loudspeakers in an installation that takes surround sound realism to new heights – literally.

Dolby Atmos is a newly developed surround-sound technology that employs any number of overhead speakers as well as traditional side-surround speakers to create an astonishingly realistic 3-dimensional sonic environment.

The Haus Zoar system employs three JBL ScreenArray 3732T loudspeakers for the main left, center and right channels. Two JBL 4642A subwoofers are located in the front of the theater and two 3635 18-inch subs are installed at the back of the theater. To deliver the full potential of Dolby Atmos sound, 50 JBL 8350 surround loudspeakers are placed at the sides of the theater and mounted from the left and right of the ceiling and aimed diagonally downward. Its high power handling capability and smooth coverage over a wide area make the 8350 ideally suited for the demanding sonic and technical requirements of Dolby Atmos soundtrack reproduction.

The loudspeakers are driven by a total of 10 Crown DriveCore DCi Network Series power amplifiers, including DCi 8|300N, DCi 4|600N and DCi 2|600N. The digital audio signal from the Dolby CP850 Atmos Cinema Processor is fed directly into the Crown amplifiers’ digital input via HARMAN’s BLU link networked audio connectivity. This eliminates the need for digital-to-analog and analog-to-digital conversion and preserves the sonic purity of the original multichannel soundtrack recording. In addition, the Crown DCi Series amplifiers include preset tunings that are optimized for various models and types of JBL loudspeakers, to further optimize the performance of the Haus Zoar system.

Commenting on the installation, Carsten Peter, Product Manager for Audio Pro Heilbronn, HARMAN’s German distributor who handled the installation stated, “Haus Zoar is truly a showcase installation that demonstrates the full potential of Dolby Atmos surround sound.”

“The Dolby CP850 Atmos Cinema processor, the new Crown DCi amplifiers, the large-scale JBL loudspeaker system and the superb acoustics of Haus Zoar all combine to create a remarkable and totally immersive sonic environment in what is surely one of the world’s most extraordinary movie theaters,” added Peter.

Miller Pro Audio, HARMAN’s JBL VTX Line Arrays and Crown I-Tech HD Amplifiers Add Pop to Fun Fun Fun Fest

NORTHRIDGE, California – For the eighth straight year, Miller Pro Audio supplied a HARMAN’s JBL line array system, powered by Crown I-Tech HD amplifiers, at the Fun Fun Fun Fest in downtown Austin, Texas. The system was deployed for the festival’s main (Orange) stage, which hosted performances by Snoop Dogg, MIA, MGMT, Slayer, Television and more.

The main PA system featured a left-right configuration of 10 VTX V25 fullsize line array elements per side, with an additional six V25 elements for front fill. The system also included nine ground-stacked G28 subwoofers, with 12 S28 subwoofers hung as a center cluster. Crown I-Tech 4×3500 HD amplifiers powered the V25 loudspeakers and S28 subs, while I-Tech 12000 HD amplifiers powered the G28 subs. The system was controlled via JBL HiQnet Performance Manager™ software.

According to Oliver, the challenges of the event ranged from the large number of acts to staying within strict noise limits from the city. “We try very hard to find a happy medium that keeps everyone as happy as possible,” he said.

With offices in Austin, Dallas, Lubbock and Oklahoma City, Miller Pro Audio was founded more than 20 years ago by Danny and Leslie Miller, growing from one truck and a small shop on a dirt road to averaging well over 1,000 shows per year spanning from clubs to top 10 shed tours. “We are a turnkey company, meaning we stock a full inventory of audio, backline, lights, video, staging, truss-built roof systems and stage lines,” said Aaron Oliver, Corporate Comptroller/Corporate Trainer for Miller Pro Audio. “We also provide production management, stage management, event planning and have a thriving install department.”

This year’s Fun Fun Fun Fest marked Miller Pro Audio’s first use of the JBL VTX line array system. “We found the VTX to have great, smooth response while remaining very musical,” Oliver noted. “The output power of the V25 was killer and the subs were powerful yet smooth and punchy. We really liked the VTX system and would love to experience what it has to offer again.”

Miller Pro Audio also owns Crown I-Tech HD amplifiers and have been pleased with the products’ performance. “We utilize the I-Tech amps to power many other products we supply and all in all, we love what the I-Tech’s allow us to achieve,” Oliver said.

In addition, Performance Manager has proven beneficial to Miller Pro Audio’s business. “We used Performance Manager for the Fun Fun Fun Fest and we use it on many other shows as well,” Oliver added. “The control it provides really helps us cut back on the need for additional hardware, which means less cases, less labor and lighter trucks—all of which translate to savings in budget.”

Martin Audio MLA’s Winning Role At National Television Awards

Britain’s 19th National TV Awards were held recently at London’s O2, where a Martin Audio MLA (Multi-cellular Loudspeaker Array) system was used to provide superior sound intelligibility for the first time.

The event, initiated in 1995 and moved to the O2 in 2010, featured Dermot O’Leary host and celebrated the most popular TV shows of the past year.

Stewart Chaney’s London-based Plus 4 Audio handled the audio in the venue, specifying the MLA for the main system. The company decided to try a different approach with the array design after talking through the system capabilities with Martin Audio Application Support specialist, Andy Davies.

“Key to the design was finding a system that could deliver consistent audience coverage while dramatically reducing the on-stage sound,” said Davies. “With most of the acceptance speeches given from an open lectern position gain before feedback was critical to the live sound mix.”

MLA easily achieved this, even allowing system tech Mark Edwards to reduce reflections from the glass-fronted VIP sections through the advanced optimization software.

The Plus 4 team fielded 22 x MLA enclosures and two MLD Downfill cabinets for the main system, with infill and outfill duties handled by their existing cabinet stock.

Using a self-powered cabinet meant the unobtrusive MLA distro racks could be concealed in the roof of the O2, dramatically cutting down cable and mains distribution requirements.

“The MLA really proved itself to us on the very first challenging show we had used it on,” stated Plus 4 Audio’s senior engineer, Mark Ballard. “We pride ourselves on achieving excellent sound quality in difficult situations and this year’s NTA show was a great result for us.”
