Celtic FC upgrades stadium sound with fully networked solution from Bosch and Electro-Voice
- PEL Services Limited upgrades evacuation and public address systems for legendary Celtic FC with phased stadium installation
- Electro-Voice pro audio EVF and EVH series loudspeakers provide improved coverage and clarity as part of integrated digital audio network
- Bosch Praesideo meets all voice alarm and communication needs, networking interfaces with legacy loudspeakers and new sound system
Celtic Football Club in Glasgow boasts Scotland’s largest football stadium and some of its most ardent fans. When the club took on the task of upgrading the stadium experience, it engaged PEL Services Limited, an electronics engineering firm based in Northolt, northwest London, to design and install upgrades to the public address and emergency sound systems in 60,000-seat Celtic Park.
“Fully networked sound reinforcement for one of the loudest stadiums ever”
With a strong stadium-wide IT network and existing public address infrastructure already in place, PEL advised the selection of Bosch Praesideo digital Public Address and Emergency Sound System with Electro-Voice pro audio loudspeakers to improve coverage, clarity and fidelity within the main bowl area of the stadium. Because both systems can be interfaced to the Dante™ networking standard, both the Bosch Praesideo system and all Electro-Voice loudspeakers are monitored and controlled remotely via Electro-Voice N8000 NetMax digital matrix controllers.
“Celtic Park is an awesome stadium, and one of the loudest places I’ve ever been for a match,” notes Vic Swain, Engineering Director for PEL. “The club wanted a state-of-the-art emergency notification system, and wanted to integrate that with an audio system that would provide clear sound for every seat in the house. It’s a challenging project, but the combined solution of Bosch and Electro-Voice works perfectly.”
The first phase of the operation was the installation of the Bosch Praesideo public address and emergency sound system, serving what Swain refers to as the “back of house” area: the internal portions of the stadium, including concourses, turnstiles, restrooms, and offices. Its open architecture and high level of redundancy makes Praesideo a scalable, reliable solution that exceeds safety standards while offering complete communications flexibility.
The stadium system is based on dual Praesideo network controllers with an audio expander interface and six strategically placed call stations. The 100V audio system utilizes legacy installed loudspeakers, all of which were tested and upgraded with Bosch line supervision sets. This enables Praesideo to check all speakers for proper line operation. The system is powered by 22 Bosch power amplifiers with onboard DSP modules.
PEL engaged Acoustics Plus, an independent acoustic consultant based in Croydon, to advise on proper deployment of the Electro-Voice loudspeakers. Research included recording SPL levels throughout a game, documenting the sonic requirements and using computer modeling to map optimal locations and dispersion patterns for full coverage. Aimed down from beneath the roof, the system uses a mix of frontloaded EVF-1152D and horn-loaded EVH-1152D, both full-range, weatherized loudspeakers from the EV-Innovation family.
“Celtic always wants to do the very best for their fans – in addition to meeting the evacuation system legal standard for Speech Transmission Index,” notes Swain, “they also wanted it to sound just as good when the place is really rocking during a big match. These EV speakers accomplish that with ease, even in problem areas. We had structural engineers and riggers working closely with the acoustic consultant to make final adjustments. A lot of preparation, but on the day the speakers were hung and aimed, it was extremely quick and accurate.”
As part of the process, Electro-Voice CPS series power amplifiers, two N8000 NetMax DSP matrix units, and a redundant fiber ring were installed as infrastructure support for the full stadium system. To date, the new loudspeakers are in place above the north stands and adjacent corner areas. Future phases will complete the installation above the south stands, adjacent corner areas, and west and east stands behind the goals.
“The integration of Bosch Praesideo in the back of house with Electro-Voice loudspeakers aiming at the area above the seats, all working together in a centrally controlled network, represents a real commitment to the safety and comfort of the fans,” he says. “It’s great to help a legendary organization like Celtic F.C. to achieve their goals.”

Indian Wells Tennis Garden selects RTS and Electro-Voice audio products for Stadium 1 upgrade
Burnsville, MN, May 2017: Located in Palm Desert, California in the Coachella Valley, Indian Wells Tennis Garden boasts 29 regulation tennis courts. At 16,100 seats its largest, Stadium 1, is the second-largest tennis-dedicated stadium in the world. Indian Wells is the host to the annual BNP Paribas Open, a major two-week pro tournament. Constantly evolving under the ownership of Oracle founder Larry Ellison, the facility recently rebuilt and refurbished Stadium 1, including a complete audio makeover that features premium products from two Bosch brands: RTS and Electro-Voice. Technicomm Industries, an area firm that has handled previous Indian Wells expansions and upgrades, was contracted to handle the upgrade.
“We had a loudspeaker demo shootout; six companies, no loyalties, and the EV products flat-out won on sound quality and aesthetics.”
“They decided to totally refurbish the main stadium last year. One goal of that change was to modernize the intercom system,” says Steve Burgess, project manager for Technicomm. “We wanted a system that could become part of our site-wide Dante audio network, and RTS was one of the few brands with that capability.”
Burgess contacted his regional RTS rep, Jeff Shorsher, to arrange a demo. Upon experiencing the system’s capabilities, Indian Wells and Technicomm agreed it was the smart choice. Operating as part of Indian Wells’ existing Dante matrix system would create great flexibility, enabling both in-house and external communications. In addition, it would enable Technicomm to address another need by eliminating equipment clutter in the broadcast booths.
“Over the years, the booths, which are quite small, had built up a variety of equipment to meet communication needs, including multiple radios, cell phones, and a computer,” notes Burgess. “By integrating everything together in a Dante network, the RTS system met every need and eliminated a ton of gear from that booth. That made a lot of people happy.”
The intercom system is based on an RTS ADAM-M digital matrix and utilizes OMNEO IP technology as its networking backbone. A total of 15 RTS DKP-4016 desktop keypanels and one rack-mount RTS KP-5032 keypanel are spread throughout the sprawling Indian Wells facility, each fitted with a gooseneck microphone.
“The programmability of the RTS intercom system put us miles ahead of our previous capabilities,” says Burgess. “We were able to route several Dante audio streams into the system and tailored each keypanel to what that operator needs on it. We were even able to incorporate the audio stream for the Hawk-Eye line judging system, which was a huge advantage for the broadcast team.”
The Hawk-Eye visually tracks ball trajectory and is used to adjudicate disputed out-of-bounds calls in professional tennis events, including the PNB Paribas Open at Indian Wells. The system requires audio input from the court effects and umpire microphones, which previously was achieved with the help of an outboard mixer.
“Having a Dante network with RTS keypanels changed all that,” says Burgess. “Now we use the speaker on the keypanel as the playback device. All we had to do was go into our Dante controller, drag the source channels over to the destination and boom, it was done. Very simple, easy to use, and sounded great. It’s a good example of the flexibility of a Dante-based system. It also eliminated a whole bunch of gear out of the broadcast booth, which was another goal of ours.”
Another major aspect of the Indian Wells upgrade was the public address system. When Technicomm learned that the Bosch family of brands included Electro-Voice, they were invited to be part of a multi-brand comparison. Quantum’s EV rep, Dave Brown, came in to consult on product selection and provide evaluation samples.
“We had a loudspeaker demo shootout; six companies, no loyalties, and the EV products flat-out won on sound quality and aesthetics,” explains Burgess. “The EVID ceiling speakers were the clear choice based on superior sound quality.”
A total of 60 EVID PC 6.2 premium ceiling speakers were installed in the facility’s premium areas, including the owner Larry Ellison’s private suite, along with other viewing suites, the champions’ lobby, and fitness center. For wall-mount indoor/outdoor applications, the facility chose the EVID 4.2, a weather-resistant design that combines attractive styling and flexible mounting with high fidelity and exceptional intelligibility.
The installation itself was a major challenge for Technicomm due to delays in the physical construction process of refurbishing Stadium 1. “We were joking that we needed more Bosch power tools, because we were basically working through February 5th, and the tournament started the next day,” says Burgess. “We ended up connecting and testing everything outside the audio cage before we deployed it. Jeff Shorsher and Calvin Ogawa from RTS really had my back, programming the system on site and interfacing it with the broadcast system. They made sure that when we put the gear out in the field, it worked right the first time. I want to thank them for their incredible support.”
While the audio and intercom upgrades were focused on Stadium 1 and broadcast logistics for the annual BNP Paribas Open, the facility is in year-round use for other events as well, including music and arts festivals, major concerts, and as a graduation venue for area high schools.
“By adding RTS intercoms and EV loudspeakers to the Dante-based system they had in place, Indian Wells now has the flexibility to provide the audio and communications for any type of event, with scalability that will make future expansion easy,” adds Burgess. “And history tells us that there will be ongoing enhancements at Indian Wells Tennis Garden for years to come.”

Electro-Voice and Bosch provide “heard, but not seen” sound solution for Houston gallery
- Electro-Voice EVID Compact Sound systems hidden amid ceiling elements create calm, welcoming ambience throughout art gallery
- Southwest Building Systems designed the system to meet gallery requirements for high fidelity and intelligibility with minimal visual impact
- Bosch PLENA matrix mixer provides wireless control of all audio in gallery, controlling zoned loudspeakers via iOS app
For their Art of the World Gallery in Houston’s River Oaks area, co-owners Liliana Molina and Mauricio Vallejo wanted to augment their guests’ appreciation of the outstanding contemporary artists they display. Southwest Building Systems of nearby Silsbee was engaged to realize this vision, and an audio visual system was installed to support artist presentations and provide background music. There is also a sound system in the VIP room, where patrons can privately view art they are considering for purchase.
“The idea was to create a warm, comfortable ambience throughout the gallery, while keeping the visual focus on the art itself,” says Brent Thornhill of Southwest Building Systems. “We knew that a combination of Bosch signal processing and the new EVID Compact Sound loudspeakers by Electro-Voice could produce the audio impact they wanted while being, essentially, invisible.”
To meet the gallery’s requirement of consistent, high-fidelity sound throughout their two-story space, Southwest Building Systems used a zoned distribution system, the Bosch PLENA matrix mixer (model PLM-8M8). Easily implemented, the mixer allows independent control of source material and volume, either directly through wall-mounted Bosch control panels and volume controls, or wirelessly through the Bosch PLENA app for iOS devices.
Because the gallery hosts presentations by the artists it exhibits, a separate sound system was needed for the front foyer and reception area. For this open space, Thornhill installed an Electro-Voice R300 wireless microphone system with both handheld and bodypack transmitters. A single Electro-Voice EVU-1082 loudspeaker, mounted above the reception desk, provides full-range, highly intelligible audio at modest volume levels from both spoken and musical sources.
The primary background audio for the main gallery spaces is provided by the EVID S44W Compact Sound system from Electro-Voice, which consists of four small satellite speakers and a single subwoofer, finished in white. Four such systems are spread throughout the gallery, with the tiny yet robust satellite speakers mounted to the ceiling beams and the compact subwoofers installed atop floating ceiling structures, making them completely invisible to the patrons. In addition, 16 Bosch LB2 speakers at ceiling level along the periphery ensure that every corner of the gallery is covered uniformly.
The final touch is the Art of the World Gallery VIP room, where clients can arrange private viewings of a piece they are considering for purchase. This private room is set up as a separate audio zone, with music provided by a single Electro-Voice EVID FM 4.2, a two-way, flush-mounted speaker set into the wall along with a Bosch rotary volume control. Co-owner Mauricio Vallejo liked the sound quality so much, he had one installed in his own office as well.
Vallejo is extremely pleased with both the sound quality and control that the system delivers for Art of the World Gallery. “Southwest Building Systems gave us everything we asked for, with clear, beautiful sound everywhere,” he says. “To have total control of the sound system, anywhere in the building, from my iPad or iPhone, is something we all love. It makes everything easy and professional, enhancing the viewing experience without interfering with it. We are very pleased.”

Electro-Voice delivers world-class sound at Hard Rock Stadium
- Installation was part of a three-year renovation to transform the facility into a destination for world-class sports and entertainment events
- Over 3,000 loudspeakers provides seamless coverage to all seating areas, concourses, offices, and public areas
- Comprehensive system was designed and installed by Diversified Systems in collaboration with the Bosch/Electro-Voice team
Hard Rock Stadium is owned by, and home to, the NFL Miami Dolphins. It also hosts University of Miami football and major entertainment events throughout the year. As part of a three-year, facility-wide renovation, the re-named facility now boasts a massively upgraded sound system by Electro-Voice.
With the stadium’s addition of a roof and massive video displays, crowd noise levels are substantially higher than the original open-air design, making even coverage critical, both in terms of SPL and frequency response. In addition to the primary task of improving the fan experience through better audio, the sound system is also used for mass notification of life safety information. The Dolphins selected Diversified Systems to design and integrate the system, charging them with the task of overcoming increased levels due to roof reflections while delivering both vocal intelligibility and musical fidelity.
Drawing from all parts of the diverse yet sonically matched Electro-Voice loudspeaker portfolio, the installation delivers concert-quality sound via 186 XLCi-127DVX line array elements, weatherized and integrated into custom-engineered frames to withstand extreme storm and wind conditions. These are augmented by EVF-1122S front-loaded loudspeakers and EVH-1152D long-throw loudspeakers to cover hard-to-reach zones like corner seating areas. In addition, 48 dual 18-inch subwoofers, custom designed for the project, add an exciting bass element that was absent in the stadium’s previous system.
An ongoing installation challenge was the management of the installation across the renovation’s phased construction timeline, requiring ongoing support of the legacy sound system while the new Electro-Voice system was being installed, tuned, tested, and deployed. To ensure even coverage throughout all seating areas, EASE modeling and intelligibility plots were critical tools in selecting the appropriate loudspeakers and their placement. Two Electro-Voice NetMax N8000 digital matrix controllers allowed the integration team to apply FIR filtering to optimize loudspeakers as needed and appropriate.
In addition to the primary task of improving the fan experience through better audio, the sound system is also used for mass notification of life safety information. Electro-Voice ceiling and surface-mount loudspeakers ensure smooth, continuous coverage in luxury suites, concourses, restrooms, offices, and all public areas throughout the stadium. This task required approximately 1800 ZX1i indoor/outdoor loudspeakers and over 1000 EVID ceiling-mounted designs selected from EV’s wide range of options.
The Dolphins team are pleased to report that the system has exceeded their performance expectations while meeting budget and timing requirements. The system is at its best when the stadium is full, enhancing the fan experience with clear, effortless coverage, and rising to the occasion to amplify crowd energy in big moments.
Whether deployed for sporting events or major concert events, Hard Rock Stadium offers a winning combination of full-range fidelity, comprehensive coverage, and high intelligibility that plays a key role in transforming the venue into global entertainment destination for large-scale events.

Electro-Voice loudspeakers fill Karbala Olympic Stadium with superb sound
The recently opened Karbala Olympic Stadium in Iraq is a 30,000-seat venue designed to host major sports, music, religious and youth events. Audio for the project was provided by Baghdad-based APCO Electronics, which provided acoustics design and participated in the actual installation as well. The company chose a sound system from Electro-Voice, creating a multi-zone digital audio system based around the IRIS-Net system control and supervising software and Electro-Voice EVH-1152 horn-loaded loudspeakers. The selected sound system stands for reliability, superior sound quality and scalability to future requirements. In addition, Electro-Voice amplifiers, microphones and wireless systems were also utilized.
The primary system requirement was that the sound system would meet FIFA football standards, which require 92 percent direct coverage and high intelligibility, with a Speech Transmission Index (STI) of 0.50 or higher. The installed system exceeds those standards, delivering 95 percent coverage with an outstanding STI (Speech Transmission Index) rating of 0.80, indicating excellent speech clarity. Next to public address announcements, the system should also be used for voice alarm and evacuation purposes.
Using EASE simulation software, the APCO team developed a design based on the Electro-Voice EVH-1152 loudspeaker system, a two-way 15-inch horn-loaded design available in six dispersion patterns. For the specific grandstand angles at Karbala Olympic Stadium, APCO used 24-each of 60×40-degree and 90×90-degree coverage patterns. Paired together, this combination provides direct, full-range coverage to all seating locations, including the difficult corner areas. In addition, two EVH-1152 loudspeaker systems with 90×90-degree dispersion are deployed individually at either end of the field to deliver audio onto the playing surface as needed.
The entire sound system is networked together using Electro-Voice N8000 Dante- enabled DSP matrix controllers and powered by Electro-Voice CPS series amplifiers with RCM-810 remote control modules. The N8000 from Electro-Voice provides complete system routing and control via graphical user interface in IRIS-Net software. The main loudspeaker system is divided into four zones, each with its own N8000 from Electro-Voice and either three or four amplifiers, with the east side zones requiring and extra amplifier to feed the field speakers. All amplifiers are connected to their associated N8000 via a gigabit Ethernet switch to handle signal routing, with redundant connectivity to ensure a reliable digital network. A fifth N8000 is stationed in the stadium’s main control room, and acts as the master unit for the entire system, routing the audio to each of the four individual zones. APCO programmed the signal processing core to handle all required audio sources, including microphones, PC-based streaming audio, emergency notifications and scoreboard audio.
Karbala Olympic Stadium represents the largest Dante system that APCO Electronics has designed and installed. Thus, the feeling of accomplishment was strong when the APCO team finally heard the Iraq national anthem being played through the Electro-Voice system at the opening ceremonies. That feeling was reinforced shortly after the event when APCO received calls from the Minister of Youth and Sport, and from local broadcaster Ishtar Media, thanking them for the outstanding audio quality.

Though it is approximately a third smaller in size than systems typically used in these environments, X-Line Advance designed to deliver outstanding audio performance, superior full-bandwidth coverage, and higher output — meaning fewer units are required to achieve desired results — while also making system design, transit, and setup/teardown more efficient and cost-effective.
Bridge Church purchases its second Electro-Voice PA rig from Prosound
In 2012, Crossroads Church in Alberton, Johannesburg, had a change of leadership and with this came new levels of required excellence including the decision to upgrade the PA system for the 400-seater church.
Prosound installed an Electro-Voice SX300 rig with Tour X and SB122 Subs, all powered by Q series amplifiers and processed by a DC-One. This system provided better speech and music reproduction than has ever been experienced at Crossroads.
2015 saw even bigger changes for Crossroads, starting with a name change to Bridge Church, building alterations and upgrades and an additional EV Rig for the Main Auditorium. Due to the existing relationship with Prosound and EV, it made sense to continue building with EV and the new ETX was the chosen loudspeaker series and consists of four flown ETX-15’s at the front of the stage, with ETX-10’s as flown side fills. Two more ETX-10’s have been added as delays about mid-way down the length of the venue. Six S-40 front fills are mounted to a ladder truss at the front edge of the stage to add some HF sizzle for the front couple of rows. Two ETX-18s 18” sub woofers handle the majority of the low end enhancement and are installed in the venue’s sub pits to the left and right of the stage, with two more ETX-15s 15” subwoofers being installed at the front of the stage to provide even bass coverage for the entire audience area.
The system is being processed by the existing DC-One from the original installation, but with the Sub-woofers running off a Mono Aux from the Midas M32 Mixing console. Existing Q series amplifiers were also re-used to power the S40 front fills in the main auditorium. The existing SX300’s and SB122 Sub Woofers have been re-used in other venues on the church premises.
Pastor Trevor Coleman agrees that the EV ETX range has proven to be very well-priced value for money, saying that “we have been pleasantly surprised by the powerful but rich quality sound that could be expected from the more high-end systems at a significantly more reasonable price.”
