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.”
