Trinity Christian Academy (TCA), a growing college preparatory Christian school in Willow Park, Texas, recently debuted a new home for its football team – Eagle Stadium – with seating for 1000, an OES digital scoreboard, and a sound reinforcement system headed by Electro-Voice and Dynacord components.
TCA Trinity Christian Academy’s new football stadium
Since its launch in 1993, the school has partnered with other local schools to use its sports facilities. Eagle Stadium is the first part of a multi-million dollar three-phase project that includes baseball and softball fields and track facilities.
Colby Howerton, U.S. southwest regional sales rep for London, Ontario-based OES Scoreboards recommended one Electro-Voice MTS-4153 three-way point-source loudspeaker mounted on the scoreboard for full audio coverage of the field and seating areas. The selected MTS-4153-64 version features a 60° x 40° coverage pattern. Designed for large-scale applications, the MTS-4153 combines four 15” woofers with dual coaxial mid/high compression drivers via a single waveguide in a design focused on cohesive high output with a strong bass response.
“The school was looking for a digital scoreboard and sound reinforcement solution that would provide audio coverage on the field and stands while offering the visibility the fans need,” explains Howerton. “To mount the loudspeaker to the scoreboard, our engineering team designed a custom bracket for the top of the center I-beam. The bracket fits the shape and bolt pattern of the bottom of the MTS loudspeaker and was easy to disguise with a scrim featuring the Eagles mascot.”
The fully weatherized MTS loudspeaker is driven by a Dynacord IPX10:4 power amplifier for fixed installations equipped with OMNEO IP networking architecture enabling Dante and OCA/AES70 networking. IPX models deliver 96 kHz DSP with low latency and a high signal-to-noise ratio and are equipped with technologies for added energy efficiency and system protection.
The amplifier is rack-mounted in the press box along with a Dynacord MXE5 Matrix Mix Engine that serves as a control center and communications hub for system devices and IP-based peripherals. The system is easily controlled and monitored via a Dynacord TPC-1 touch panel controller working with the mix engine. Using SONICUE Sound System Software, installers can freely configure the TPC-1 interface screen with customizable controls that are enhanced by images, such as schematic diagrams, school colors or corporate logos.
“One of the features the school required was a system that could easily grow,” adds Howerton. “Not only might the stadium itself expand with additional guest seating, but the additional phases will require networked systems. This system allows for all that and more – it seems simple, but it’s quite sophisticated. This was one of the first applications done with an MTS loudspeaker, and we will recommend similar packages again.”
Dynacord electronics have been used to power over 200 Electro-Voice loudspeakers at the impressive new stadium at Tizi Ouzou in Algeria.
The recently completed 50,000-seat venue is the home of soccer team JS Kabylie and has been built adhering to the latest UEFA standards, covering everything from the pitch to the technical equipment. The Dante audio-enabled sound system with integrated redundancy was designed by Turkish partner Atempo and meets the sporting requirements, but also provides flexibility to host other events.
A total of 112 EVH-1152D/94 cabinets have been arrayed in clusters of three and flown from the stadium roof to cover the various bowl seating areas. A further 102 EVID-S5.2T provide the under-balcony fill to ensure an even sound level throughout the stadium, and four EVID-S8.2 complete the system. 12 Dynacord IPX10:8 power amplifiers drive the EVH and EVID-S5.2T loudspeakers for the bowl; the EVID-S8.2 models are powered by a pair of L1300FD amplifiers. An MXE5 Matrix Mix Engine provides powerful DSP processing, with SONICUE Sound System Software used for efficient setup and control.
Electro-Voice EVC Vari-Intense loudspeakers help to tackle challenging acoustics while blending into the architecture at Binh Thuan Roman Catholic Church
Dynacord L-Series amplifiers provide power and processing for extensive new sound system
Electro-Voice hanging microphones ensure that harmonization in the choir can be heard throughout the sanctuary
A sound system solution comprising Electro-Voice loudspeakers and microphones and Dynacord amplifiers has enhanced audio intelligibility for the congregation at Binh Thuan Roman Catholic Church in Ho Chi Minh City, Vietnam. The solution was installed by Duy Hoa Phat Corp and was specified to overcome the reverberance inside the church.
Established in 1966, Binh Thuan church is a notable religious site within Vietnam‘s Catholic community and one of the biggest churches in Ho Chi Minh City. Since its original construction, the church has been through several renovations and expansions. However, as the church building has grown, its existing sound system, which had been selected more for its aesthetic than acoustical properties, has not been able to keep up.
The church decided it was time for a new audio solution that could deliver high-quality sound across the whole chancel with absolutely no delay or echo – a challenge, since the reverberation time there is more than four seconds. In addition to this, the loudspeakers needed to blend into the church’s bright interior design to be visually unobtrusive.
The answer was found in white versions of models from the Electro-Voice EVC family of compact loudspeakers for fixed installation. A pair of EVC-1122-VI Vari-Intense 12” two-way loudspeakers address the main congregational seating area, supported by seven EVC-1082 8” two-way loudspeakers. The EVC-1122-VI has a unique asymmetrical horn design which allows uniform coverage of rectangular spaces, ensuring sermons can be heard clearly by every member of the congregation during services. In addition to the EVC models, a pair of EVID S4.2TB and a further two Bosch LB2-UC30-L1 compact installation cabinets complete the solution. Power for the audio system is provided by five Dynacord L1300FD 2x 650 W DSP amplifiers.
Electro-Voice microphones ensure an equally high standard of audio quality at the input end of the signal chain. Four wired ND96 dynamic supercardioid vocal mics are joined by an equal amount of RE3 UHF wireless systems featuring ND96 handhelds. Completing the microphone selection are 12 RE92HW cardioid hanging mics to capture the harmonies of the choir.
This combination of equipment precisely addresses the church’s needs, especially in delivering the highest level of clarity for speaking and singing voices. And, importantly for a worship application, the durability and quality of Electro-Voice and Dynacord products mean that Binh Thuan Roman Catholic Church will be enjoying the advantages of its new audio solution for many years to come.
Harry Potter fans may recognize the Glenfinnan viaduct, as it was part of the scenery in the Harry Potter films showing the Hogwarts Express puffing through the beautiful landscape of the Scottish Highlands. But there is another famous connection, the Glenfinnan Highland Gathering, which features a traditional program including highland dancing, athletics, caber tossing, heavy weight events, bagpiping and more.
To provide optimal sound reinforcement with defined directivity for the large event area, Glasgow based rental partner The Stage Group opted for the high-output MTS point-source loudspeaker systems. As if by magic, only two MTS loudspeakers driven by one IPX20:4 power amplifier delivered crystal clear commentary, music, announcements and vocals across the large six-acre site.
Open Air Gampel in the middle of the alps is one of the biggest live music events in Switzerland. The four-day festival near Bern presented a popular lineup of top acts such as Sido, Mark Forster and Robin Schulz, attracting up to 30,000 attendees at the end of August. Since its foundation in 1986, local rental company FreepowerEventtechnik is in charge of the sound reinforcement for all stages of the festival. The team once again relied on a powerful combination of Electro-Voice X2 line-array loudspeakers powered by Dynacord TGX series amplifiers.
The main sound system for the White Stage saw a total of 30 X2 line-array elements plus 24 X12-128 subwoofers driven by four SR20-TGX system racks from Dynacord. The 10U TGX system rack is preconfigured with three TGX20 DSP amplifiers plus two independent network switches for glitch-free operation and offers a variety of professional features such as integrated sliding rack doors, customizable I/O options, and a reversible mounting for the power distribution. SONICUE Sound System Software handled quick and comprehensive configuration and control of the entire PA.
Bielsko-Biała, Poland, July 2022 – An extensive public address system from Electro-Voice and Dynacord has been installed at Cavatina Hall. Located in the vibrant, historic city of Bielsko-Biała, amongst the Beskidy mountains in southern Poland, the six-story building counts over 9,000 square meters of top-tier office space, a cutting-edge recording studio, a chamber music room and a majestic 1,000 capacity concert hall. The venue itself is owned by leading Polish development company Cavatina and is the first privately owned and funded concert hall in Poland.
As a large, multi-use facility Cavatina Hall required an extensive solution to cover public address across its various areas. This needed to be flexible enough to meet the differing needs of office workers and theatregoers and led to Audio Plus, the company responsible for the coordination and co-designers of the solution, turning to the extensive Electro-Voice and Dynacord portfolio.
The heart of this solution is electronics from Dynacord, with an MXE5 Matrix Mix Engine alongside an IPX10:8 power amplifier. IPX multi-channel amplifiers are dedicated for fixed installations and offer sophisticated speaker processing. IPX also features Dynacord’s unique variable load drive (VLD) technology. For each channel, the user can determine whether Low-Z or High-Z 70V/100V loudspeakers are driven without the need for an output transformer via direct drive technology. The IPX10:8 was the perfect choice for this project due to its ability to harness this technology across eight channels.
“The IPX 10:8 is at the core of the sound system – we wanted something that was technically optimal in terms of control and this amp allows each channel to be individually operated, along with analog inputs from Dante and OCA via OMNEO network inputs – it’s a highly flexible solution for us,” explains Stanisław Mielczarek, Tech Support Engineer, Audio Plus. “MXE5 was chosen as it’s a universal processor that complements other systems in Cavatina Hall – through SONICUE Sound System Software. It integrates perfectly for this kind of project – allowing us to have full control of the entire system of signal routing and signal processing for public address speakers.” adds Tomasz Ibrom, Project and Installation Engineer, Audio Plus, who was responsible for the system integration at Cavatina Hall.
The Dynacord electronics are driving a large 100V Electro-Voice loudspeaker solution combining the strengths of the EVID ceiling and surface mount ranges. “EVID speakers offer a big spectrum of models in the series and were the ideal choice because of their mounting capabilities,” Ibrom explains. “Each piece is exactly fitted for its location.
”In the main auditorium, a pair of Electro-Voice FM6.2 speakers have been hidden behind the wooden sound panels either side of the stage. These are linked to the RTS intercom system and used for addressing the performers onstage. The stage manager or event director can use the system via an Electro-Voice wireless mic to communicate with the musicians during rehearsals. “This additional system works perfectly because the speech is super-intelligible and the speakers are completely invisible,” says Ibrtom. “The team at Cavatina Hall are really happy with it.”
Staying on stage, Electro-Voice microphones have also been selected to cover a wide range of vocal and instrumental needs. This includes everything from the RE97Tx micro-headworn condensers, to ND44, ND46 and ND66 instrument mics, as well as the iconic RE20 and RE320 Variable-D models.
The Hall now boasts superior efficiency in terms of connectivity, which fits in well to the innovative aesthetic of the multi-functional building. Marcin Smolik, Producer and Managing Director at Cavatina Hall concludes: “We are at the forefront of Europe among the few venues that have such a system. Our technology is a treat for artists and for the viewer, it means quality.”
