Sound reinforcement systems from Bay Area audio innovator, Meyer Sound, played a supporting role in the Super Bowl 50 festivities, the biggest Super Bowl week ever celebrated and one that the Super Bowl 50 Host Committee called “uniquely Bay Area”.

In their quest to make the game-day sound for this Super Bowl the best ever, NFL production leaders tapped Meyer Sound to help enhance the February 7 experience between the Carolina Panthers and the Denver Broncos. Meyer Sound’s technical team worked with ATK Audiotek of Valencia, California, to rig SB-1 parabolic long-throw sound beams and SB-3F sound field synthesis loudspeakers at Levi’s Stadium, ensuring that the full house in the upper deck can enjoy game day.

State-of-the-art Meyer Sound solutions were also to be found enhancing the fan experience at many of the Bay Area events leading up to Super Bowl 50. The company’s top-of-the-line LEO® Family of line array loudspeakers supported Metallica’s trademark sound at AT&T Park on Saturday, and powered the party at Project Nightclub on Pier 70 for performances by Dave Matthews Band and Pharrell Williams on Thursday and Friday nights, respectively. The Red Hot Chili Peppers performed at Saturday’s Super Bowl eve show there.

In addition, longtime fans at the San Francisco Symphony experienced Meyer Sound’s newest product — the LEOPARD™ linear sound reinforcement system — in two special evenings of big-game orchestral celebrations at Davies Symphony Hall.

The systems at AT&T Park, Pier 70 and Davies Symphony Hall were supplied by Martinez, California-based Pro Media/UltraSound, a company perhaps best known as the Grateful Dead’s sound system supplier since 1980.

Helen Meyer, Meyer Sound’s executive vice president and co-founder, commented before Super Bowl 50:

All of us at Meyer Sound are thrilled to play a role in the big game and in all the festivities leading up to this extra special 50th anniversary.

Of course, we aren’t taking an official corporate position on who we’d like to win, but considering that 30 Meyer Sound CAL™ column array loudspeakers are installed on the upper deck of Bank of America Stadium in Charlotte, there might be a slight tilt toward the Carolina Panthers.

Unfortunately for Meyer, it was the Denver Broncos who finished up as the worthy winners of Super Bowl 50.

Founded by Berkeley residents John and Helen Meyer in 1979, Meyer Sound designs and manufactures its products, including all of the self-powered loudspeakers and accompanying digital signal processors deployed for these events, on its ever-expanding Berkeley campus.


New stadium audio for 2015 UEFA European Under-17 Championship

Comments Off on New stadium audio for 2015 UEFA European Under-17 Championship

Arena Sozòpol is one of the four venues that will host the 2015 UEFA European Under-17 Championship. Completed in plenty of time, the 4,000-seat host venue has undergone a full reconstruction with new grandstands and amenities.

Sozòpol is an attractive ancient seaside town located 35km south of Bulgaria’s second largest city, Burgas, on the beautiful Black Sea Coast. It is one of the country’s major seaside resorts, internationally known for the Apollonia art and film festival.

Burgas-based Pro Audio Ltd was commissioned to design and install the audio for the new stadium.

Stanislav Petrov, Managing Director of Pro Audio explained their design:

High intelligibility, even coverage and good sound levels with headroom were all main criteria, so Community’s R SERIES were the natural first choice. Their accurate dispersion also avoids unnecessary overspill in the vicinity of the stadium and their all-weather reliability is second to none.

The project was accomplished in two stages, as each of the new grandstands was built. Eight Community R.5’s were used for the main stand, with two R2’s covering the playing field. In phase two, an additional nine R.5’s were installed to provide complete coverage of the second stand.

Mixing for the system is handled by an Allen & Heath analogue console with DSP and routing via a TOA M-9000M2 with remote control units. The Community loudspeakers are powered by QSC CMX series amplifiers. The system uses a Sennheiser ew300 4-channel mic system and a TASCAM CD player provides a source for music.

Petrov added:

The system is loud and clear and provides excellent coverage of every seat. Visitors can enjoy themselves, comfortably hearing the commentary and entertainment even when excitement is at its highest and the crowd at its loudest.

Texas Football gets an upgrade at Buddy Moorhead Stadium

Comments Off on Texas Football gets an upgrade at Buddy Moorhead Stadium

Named after a legendary football coach and home to the Conroe Independent School District’s numerous High School athletic teams, Buddy Moorhead Stadium continues a proud tradition of Texas high school football with a modern facility seating over 8,400 fans. 


The stadium’s artificial turf and competition track were recently upgraded, but for several years, its sound system had been unreliable and fans often complained about intelligibility.


In 2014, the Conroe school district chose TASC A/V to provide a new sound system. TASC designed a system based on Community R6-51 high-output, horn-loaded loudspeaker systems.


TASC Project Manager, Anthony DiDonato, explained:

Our only real option for locating the loudspeakers was at the scoreboard. So, we needed an extra-long-throw box to cover over 150 yards. Plus, this is Texas football – we needed high SPL at long distance to get over the crowd!


Lab Gruppen amplifiers power the system, which also includes a Montezuma DSP mixer and Shure ULX wireless microphones for field use and game announcements. Two Symetrix Radius DSPs provide DSP functions and loudspeaker management communicating over a dedicated DANTE V-LAN network provided for the project. TASC installed twelve Community C6 ceiling loudspeakers in the press box with zone volume controls and a shotgun mic on the outside of the press box to monitor the game and half-time events.


The system was installed in August of 2014 in time for the Tigers’ first game of the season. DiDonato says the response from the district client, Conroe ISD, has been highly enthusiastic, with Director of Athletics Danny C. Long reporting that his team is “ecstatic” with the new installation:

TASC A/V really went the extra mile to design and install a rock-solid system and ensure that it produces quality sound in every part of the stadium.


New audio system adds excitement at Yager Stadium

Comments Off on New audio system adds excitement at Yager Stadium

With the success of its football program, Miami University began a series of upgrades to Yager Stadium in 2003. The improvements to the 24,286-capacity venue included a new artificial turf playing surface, a broadcast-quality field lighting system and a large screen video scoreboard.


However, the existing stadium sound system was retained, forcing RedHawks football fans to endure inconsistent coverage and poor music quality. For several seasons, the university supplemented the system with rental equipment from integrator Loud and Clear. But, in 2014, they asked Loud and Clear’s Eric Cimini to provide a completely new installed system to eliminate the need for rental equipment, provide uniform coverage and enhance the fan experience with better musical performance.


During system planning, the university considered a distributed system but decided to stay with the existing end-firing scoreboard design to utilize existing wiring and avoid the cost of the stadium structural changes needed for a distributed system.


The new scoreboard system uses two Community R2-52 and ten R2-64MAX loudspeakers to cover the stands and the field. Three R6-Basshorn woofers provide long-throw LF coverage and six VLF218 subwoofers, which are rolled out below the scoreboard during games, supplement the LF performance for music. Community R.5 and R.25 loudspeakers provide coverage beneath the stands, in restrooms and in the concessions area.

The system is powered by Crown iTech amplifiers and utilizes a Peavey Media Matrix for mixing and primary DSP functions. Loud and Clear added an Audio-Technica wireless lapel microphone for field use and a pair of Community dSPEC DSP processors for zoning and loudspeaker management. The dSPEC zoning also allows loudspeakers covering the field or the stands to be muted during practice.


Cimini says system commissioning went well and the completed system provides uniform coverage all the way from nearby stands to the far end zone seating. When the system was first turned on, the university’s athletic director was amazed at the clarity and quality of the sound, as Cimini advised:

The volume from the Community R2-MAX loudspeakers is mind-boggling and the system has amazing clarity at these sound levels.

Leading-edge audio system for Bialystok’s world-class stadium

Comments Off on Leading-edge audio system for Bialystok’s world-class stadium

Białystok City Stadium is located in the largest city in Northeastern Poland and the capital of the Podlaskie Voivodeship. The stadium has undergone major redevelopment and substantial new construction and now meets the highest world standards for modern sports facilities. The new 360 degree grandstand boasts a capacity of 22,400 and the venue also incorporates conference rooms, a VIP room, a restaurant area and a shop for fans of the local football team.


The sound system was designed by Tommex Żebrowscy Sp. J. and installed by Zeto S.A. The system is based on Community loudspeakers and Dynacord electronics. Białystok-based integrator Zeto S.A. completed the installation in time for the opening of the modernised venue, which took place in July 2014. Zeto’s Zbigniew Kaczmarczyk was project manager for the installation.


The main system is housed in the commentary room and linked to four separate amplifier rooms. The audio signal is transmitted over the stadium’s network using the DANTE protocol and is triple redundant, with two fiber rings and a turbo function ring. It is the largest system based on the DANTE protocol operating in any stadium in Poland.


The system uses a Dynacord CMS 2200-3 audio mixer, 16 x 16 DSP equipped digital control matrix and a DPM 8016 digital matrix manager. The audio matrix is 32 × 32 and handled by Dynacord’s P 64 digital audio matrix units. By using the IRIS-Net network, each element of the system is continuously monitored and all operations are controlled via a Dell all-in-one touch-screen PC.


A DPC 8015 microphone, located on the Events Security Commander desk, has full priority over other audio signals, enabling the effective communication of voice messages in the event of non-standard events.


The main loudspeaker system comprises forty-eight Community R2-474’s and three R2-52’s. The combination provides the dispersion patterns required for complete coverage of the stadium’s 360-degree grandstand. In addition, thirty-eight R.25-94’s and forty-one R.5-99’s provide audio for the stadium’s internal promenades and public areas around the building.


Twenty Dynacord DSA 8410 4-channel amplifiers provide a total of 80kW to power the Community loudspeaker systems.


Marcin Zimny of Tommex commented:

Visitors to Białystok City Stadium will not only enjoy their sports with great audio quality, but they can also be assured that their safety is our primary concern with reliability being a fundamental consideration in the design and every component of the system.

One Systems upgrades University of Indianapolis Key Stadium for football fans

Comments Off on One Systems upgrades University of Indianapolis Key Stadium for football fans

The University of Indianapolis (UIndy) – a private university located minutes from downtown Indianapolis – recently upgraded Key Stadium with a One Systems sound reinforcement system.

As a NCAA Division II school, UIndy is recognized for having one of the best athletic programs in the USA. The decision was made to upgrade the system in order to accommodate its expanding football fan base and game day experience.

The school administration tapped Tech Electronics of Indiana to assist in the design of a new system.

Bob Brubeck, Assistant Athletic Director for Facilities & Game Day Operations at UIndy, explained:

Having worked with Tech Electronics before, we knew they were the best fit for the job. Their project proposal provided exactly what we needed to improve the sound quality and game experience at Key Stadium.

Jeff Watson, Director at Tech Electronics of Indiana, headed up the project. The school was in need of a system that had enough power to overcome the crowd noise and cover the visitor sidelines, Alumni tent, the south parking lot and the home bleachers.

Watson said:

We put together a system that took their current and future needs into consideration. Our previous experience with One Systems direct weather loudspeakers made the decision an easy one. They aren’t just models with direct-weather capability, they are incredible, high-performance loudspeakers built for outdoor use.

Watson specified a total of nine One Systems loudspeakers to cover the complex. Five 112IM 12-inch, two-way full range loudspeakers were mounted to the home side press box to cover the home bleachers. Four 212CIM 12-inch, two-way loudspeakers were mounted 65 feet above the ground on the home side light poles to cover the entire football field and surrounding areas.

Watson added:

One Systems loudspeakers provide top performance sound quality while being impervious to the Midwest’s sporadic and hazardous weather conditions. The University is extremely pleased with the new system. It definitely takes the game day experience to a higher level.

Tech Electronics also supplied three Crown Audio CTS600 loudspeakers to power the system. The units are housed in a new lockable wall mounted equipment rack located in a storage area at the stadium. The rack is also home for a Biamp Systems Nexia SP digital signal processor used to EQ and fine tune the system.

Louisville Football Stadium delivers high-impact game experience with Meyer Sound LEO

Comments Off on Louisville Football Stadium delivers high-impact game experience with Meyer Sound LEO

To amplify the home-game atmosphere and bring the 55,000 fans closer to the on-field action, Papa John’s Cardinal Stadium at University of Louisville has chosen one of the most powerful loudspeaker technologies available today, Meyer Sound’s LEO™ linear large-scale sound reinforcement system, with the 1100-LFC low-frequency control element and SB-3F sound field synthesis loudspeakers. Selected for its sheer power and remarkable ability to project sonic clarity and impact over long distances, the system was chosen by recently retired, long-time stadium manager K.C. Scull after experiencing the impressive LEO system at Ohio Stadium in Columbus.


Mike Dewees, head technician at Acoustical Audio Designs, the company contracted for operation and maintenance of the stadium systems, commented:

The performance of the new Meyer Sound system at Cardinal Stadium has been excellent. There are no more complaints about not being able to understand the announcer. Now the music quality is very good throughout the bowl with consistent coverage in all seating areas, and the system has incredible headroom.


Packed tightly into the north end scoreboard, the system features 24 LEO-M line array loudspeakers deployed in five arrays: two main arrays of eight each for the lower bowl plus two additional arrays of five and three LEO-M loudspeakers for the upper seats on the east side.


Eleven SB-3F loudspeakers throw crisp, mid-high-frequency sound to the far end seats and an upper deck terrace over 700 feet away. Eight 1100-LFC low-frequency control elements arranged in cardioid arrays supply low end, and two arrays of three-each MICA® line array loudspeakers provide additional coverage. A Galileo® loudspeaker management system with one Galileo 616 AES and two Galileo 616 processors handles drive and optimization.


Consultant Ron Baker, noted how the power of LEO and SB-3F has helped to solve a difficult packaging problem:

Everything had to be squeezed into the same scoreboard structure as the old system. We had to apply creativity to shoehorn all the extra horsepower into the same small engine compartment.


For Dewees, the extra horsepower is much appreciated:

The old system was susceptible to changes in air temperature and wind. Now, with LEO, we can get over peak crowd noise as needed with no distortion.


Dewees also noted that the additional horsepower calls for adjustments and restraint on the part of users:

Because the potential level is off the charts, our only issue so far has been getting the operators to use that power wisely.


The new system for the stadium was designed by Ron Baker and Justo Gutierrez of Dallas-based consultants Wrightson, Johnson, Haddon & Williams. Installation of the system was contracted in two phases, with the SB-3F loudspeaker system installed by Parsons Electric of Minneapolis. The LEO system was installed by Florida-based Pro Sound & Video under the supervision of Brian Smith of the Pensacola office.


Two of the five largest American stadiums use Meyer Sound SB-3F sound field synthesis loudspeakers, including Michigan Stadium (capacity: 109,901) and Ohio Stadium [capacity: 104,944).

Tierp motorsport track expanding events through sound

Comments Off on Tierp motorsport track expanding events through sound

The sound is ear-splitting: the howl of race-tuned engines vying with each other to strip paint by SPL alone from the concrete walls of the long U-shaped arena at Tierp, purpose-built track on an old military airfield in central Sweden. The brainchild of Lief Andréasson, this derelict patch of perfectly level wasteland has been turned into one of the most modern drag racing arenas in the world – with a host of other events planned, including concerts. It’s 2.51km (1.56 miles) of motorsport racetrack just 120 km (75 miles) north of Stockholm with the capacity for 20,000 spectators.

Tierp's sound system overcomes trackside volumes.

Tierp’s sound system overcomes trackside volumes.

Tierp Arena co-director Lars Erik Lindberg enthused:

We’ve built one of the best race tracks in the world, one of the best facilities for drag racing anywhere.

Its inaugural year saw one European Championship race, and in 2012 two European Championships and two Swedish Championship races.

He continued:

The reason it’s one of the best is simple: the track is concrete so it’s really flat and stable; not so sensitive to weather or temperatures. Modelled on Formula 1 tracks, it now has one of Sweden’s longest straights, plus open hairpins and very fast corners. And the facilities are excellent: grandstands for 20,000 people, many toilets, showers, and a large pit area with all the facilities the teams could want.

If drag racing is loud, it follows that the commentary has to be a few dBs more potent still. Karl-Gustaf Kahlau, of Renkus-Heinz Sweden distributor Luthman SMTTS AB, said:

The key to the audio for a drag racing audience is, of course, to make it loud so the audience can hear what the commentator is saying above the noise of the cars. What they’ve done at Tierp Arena is to use line array modules that are powerful enough, but compact enough not to obscure sightlines. When the audience is watching a race, they obviously don’t want a bulky sound system in the way.

With our help, they decided on low profile PNX102/LA line array modules, 24 boxes in total, bolted in pairs to customised steel ground frames to make 12 independent freestanding clusters, that they could place along the length of the racetrack at ground level pointing upwards towards the audience.

The line array modules are matched to high efficiency Powersoft amplifiers via a weather-insulated network of pre-installed underground cables under the racetrack, and weatherproofed ground facility panels, all running back to the amp rack room in the main building.

The track can deploy the sound system on other parts of the site for presentations, speeches and potentially for a rock concert for 10-20,000 people.

WET X speakers devised for outdoor applications

Comments Off on WET X speakers devised for outdoor applications

Battling the elements is part and parcel of stadium management so products designed specifically for outdoor use are welcome. Community has designed a new series of loudspeakers, WET X, which comprises 13 new models of its WET Series. WET X’s hand-laid fibreglass enclosures are internally lined with marine-grade plywood. Community says that the speakers use innovative drivers to provide premium sound quality for both outdoor and indoor venues.

WET X loudspeakers contain a large diaphragm 1.4-inch exit high frequency compression driver and can produce the same output levels as the largest WET II loudspeakers but in enclosures only half the size. The low frequency cone and internal circuitry have Community’s proprietary Envirotech coating for improved weather-resistance. The WX218SDF, a downfire dual 18-inch model, adds an ultra-high-performance subwoofer to the line.

WET X enclosures feature a modified trapezoidal silhouette that brings a more traditional look and feel to the loudspeakers while providing the same outdoor direct exposure resistance and streamlined shape to reduce wind load.

All of the wood is resin-sealed to reinforce the enclosure’s weather resistance. The smooth glossy outer layer is available in black or white, with custom paint colours optional. All models include a dual-layer powder-coated stainless steel mounting bracket.

Rodeo Houston rocks with world’s largest L-ACOUSTICS kit

Comments Off on Rodeo Houston rocks with world’s largest L-ACOUSTICS kit
The Houston Livestock Show and Rodeo drew a record-breaking 2.5 million people this year. Rodeo fans and concert-goers appreciated the vast L-ACOUSTICS sound system.

The Houston Livestock Show and Rodeo drew a record-breaking 2.5 million people this year. Rodeo fans and concert-goers appreciated the vast L-ACOUSTICS sound system.

Billed as the world’s largest live entertainment and exhibition event, the annual Houston Livestock Show and Rodeo – with rodeo and concert events known as RODEOHOUSTON – is also one of Texas’ largest charities, having contributed over $330 million to the state’s youth since 1932. But ask any of those youth about this year’s event and they’ll likely rave on about Reliant Stadium’s stellar three-week rodeo and concert series, which was heard via the world’s largest L-ACOUSTICS K1 stadium system provided by LD Systems, Inc.

From 25 February to 16 March, the 72,600-seat stadium hosted a nightly double bill of two hours of rodeo action immediately followed by an hour-long concert from a world-class artist. To be expected, the concert list included a long list of contemporary country music favourites like Blake Shelton, Luke Bryan, Zac Brown Band, Kenny Chesney and Jason Aldean. But the schedule was also interspersed with a fairly broad range of other popular musical artists, including Mary J. Blige, Bruno Mars, Pitbull, Styx, Demi Lovato and Julión Alvarez, among others.

This year, for the very first time, RODEOHOUSTON also extended its normal 20-day run by an extra night for a concert-only performance from the iconic George Strait. Without a rodeo event scheduled earlier that day, an additional 7,400 seats were added to the floor area enabling the sold-out show to break Reliant Stadium’s largest attendance record with 80,020 fans present.

Using L-ACOUSTICS’ SOUNDVISION acoustical modelling software, the manufacturer and LD Systems collaborated on an ideal system design for Reliant Stadium that utilised 280 enclosures powered by 48 LA-RAK touring amplifier racks. The system comprised two concentric rings of loudspeakers – an inner ring of K1 arrays to address the lower bowl seating areas, plus an outer ring of KUDO arrays to cover the upper bowl seats.

To accommodate the extra 7,400 floor seats for the final evening’s concert, LD Systems supplemented its system with four six-cabinet KUDO arrays, two six-cabinet KARA arrays and four four-cabinet ARCS II arrays, complemented by 24 SB28 subs on the floor and 13 self-powered 108P enclosures for front-row coverage. This brought the total L-ACOUSTICS loudspeaker count for the closing show up to 369.

I don’t think we were quite prepared for how much it seemed to improve the stadium’s acoustics for our rodeo announcers. When they realised that the audience was hearing them very clearly and warmly, they began to perform better as well, toning down and talking naturally rather than pushing and straining like they had to in the past,

said Show Interim President and CEO Leroy Shafer.
