The College Of San Mateo Overhauls Its Athletic Facilities’ Audio Systems

Below is an excerpt from a feature story in the March issue of Systems Contractor News.

The San Mateo Community College District, College of San Mateo, Skyline College, and the Canada College recently updated the sound systems for several of their sports facilities. Some of the prior systems were around 30 years old or just non-existent, in the case of several outdoor fields.

For all the systems installed, Technomad Vienna and Noho loudspeakers were used. “We found out about Technomad from Lloyd McKinney Associates, and they brought us some to test out,” said Jim Petromilli (Director of Instructional Technology at San Mateo Community College District). “We were impressed with the sound quality and how rugged they were. We worked with them to design a first installation and had nothing but accolades about the sound quality, so we just moved forward and have been very pleased with them.”

Henderson State University Installs Technomad

Henderson State University in Arkansas has installed eight Technomad weatherproof outdoor loudspeakers at Carpenter-Haygood Stadium, home of the Henderson State Reddies, a Division II football team. The new loudspeakers, first used at the September 20 home opener, replaced antiquated horn system and improved voice and music intelligibility at the 10,000-seat stadium.

The university purchased six Technomad Berlin 15/H Install loudspeakers and two Technomad Paris 616 loudspeakers. It also purchased two PA racks filled with new mixers, amplifiers, signal processors and other equipment. Four of the Berlin 15/H Install loudspeakers are installed on the press box above the home bleachers, with the other two on poles next to the visitor bleachers. The Paris 616 loudspeakers are installed lengthwise on the ceiling of the press box overhang to provide a direct audio source to the expensive alumni seats underneath. Henderson State University purchased all the equipment and products through Troxell Communications.

The Technomad Berlin and Paris loudspeakers blend exceptionally well, to the point that it sounds like one enormous loudspeaker covering the entire stadium, said Jim Wilhelm, multimedia specialist for Henderson State University. We positioned the four Berlins on the press box so the middle two are pointing straight ahead and the far left and right loudspeakers are at a 45-degree angle. I wanted to ensure that those seated in the far upper corners are hearing the same quality as those at dead center. And, while the Berlins are still audible from under the press box, the Paris loudspeakers provide a more personal audio source for the alumni who pay for those seats.

Technomad Loudspeakers Installed in Multiple Sports Venues Across San Mateo Community College District

Three campuses standardize on Technomad loudspeakers for indoor gymnasiums and outdoor stadiums

BOSTON, April 29, 2008 – Technomad Associates, LLC today announced that San Mateo Community College District in California has standardized on Technomad weatherproof loudspeakers on its three Bay Area campuses. Skyline College in San Bruno; Canada College in Redwood City; and the College of San Mateo are home to multiple indoor and outdoor venues now using Technomad Vienna 16 and Noho C loudspeakers for live sports and event coverage, with additional venues to follow as the district moves closer to completing a multi-year, multi-venue upgrade project that covers everything from field surfaces to bleachers to PA systems.

This is an ongoing project with one facility upgrade after another, and we have found the Technomad loudspeakers to be highly versatile with excellent audio quality both indoors and outdoors, said Jim Petromilli, Director of Instructional Technology at the San Mateo Community College District. Outdoors, the weatherproof design is ideal for our three campuses, all of which have very distinct microclimates that can include high heat, heavy rains, and rust from bay moisture. We have also found that the Technomad Vienna loudspeakers perform exceptionally well in our gymnasium at Skyline College for basketball, graduations and other events, and we are planning a similar installation in a second gymnasium.

The outdoor Technomad installations as integrated by Petromilli and his team include: five Noho C loudspeakers for Bulldog Stadium, the football stadium at College of San Mateo, with a sixth Noho C assigned to a nearby track and field area; nine Noho C loudspeakers for three baseball diamonds; two soccer fields, each with two Noho C loudspeakers; and three Vienna 16 loudspeakers for a new softball field that opens this spring.

Lloyd F. McKinney Associates of Hayward, California, procured the loudspeakers from Technomad for all venues, citing the weatherproof design as ideal to handle the different weather elements of the three campuses. The company also led the systems integration project for the gymnasium at Skyline College, home of the Skyline College Trojans, due to the height and complexity of the loudspeaker installations and system wiring. Twelve Technomad Vienna 16 loudspeakers were mounted onto concrete beams or steel structures in the gymnasium, with quad amps to drive selected speaker banks depending on the event. Each side of the gym features five Vienna 16 loudspeakers, with every other one facing the opposite direction to maximize coverage. The final two Vienna 16 loudspeakers were installed on a steel structure above the main basketball hoop, aiming down toward the center of the auditorium.

According to Rick McKinney, Vice President of Lloyd F. McKinney Associates, Petromilli and his team requested an indoor demo after experiencing the high audio quality of the initial outdoor Technomad installation at Bulldog Stadium, adding that the wide horizontal coverage pattern of the Viennas and Nohos allows the colleges to cover wide bleacher areas without hot spots.

Indoor reverb is always challenging in a gymnasium since you’re dealing with hardwood floors, concrete in bleachers and other acoustical challenges, said McKinney. The Vienna 16 loudspeakers provide plenty of power and voice intelligibility for Skyline College events, with a smooth and even audio dispersion throughout the bleachers. In fact, the two Viennas above the main basketball hoop cover the entire gym quite well on their own, but the additional speaker banks give Skyline College plenty of flexibility to orient the sound system to meet different requirements depending on the event.

According to Petromilli, the Skyline College gymnasium is the crown jewel of the district-wide sports facilities upgrade a complete remodel of an existing facility that adds a video projection system and free Wi-Fi in addition to the new floors, bleachers, and PA system.

The Technomads replaced a poor audio system that produced a massive echo, he said. It was difficult to hear in certain areas and we received many complaints. The Technomads bring a huge improvement in voice intelligibility, and the audio quality has improved our attendance in a very competitive market. The PA system has become part of the events at Skyline College, with music and additional entertainment for attendees to create an enjoyable experience.

The Noho C loudspeakers at Bulldog Stadium replaced aging horn systems that produced highly distorted, unintelligible audio. Three Noho C loudspeakers are installed on a press box facade at the 50-yard line, with two more mounted on light poles at the opposite side of the field.

“We opted for multiple loudspeakers that produce high quality audio at a lower level so we could achieve even distribution through the crowd,” said Petromilli. “This is also very important during track events; with so many events on the field, the participants can clearly hear their events being called. This includes the separate area where shot-put, javelin, and other events are held. And during football season, music is a more integral part of the experience, especially during warm-ups. The Technomads provide a pleasant musical output in addition to clear voice reproduction. We literally have people from visiting teams all over southern California knocking on our press box door complimenting us on our sound system, music, and overall presentation.”

Technomad Surpasses 17,000 Mark for Loudspeakers Shipped

Company continues to manufacture entire product range in the USA as it approaches 13 years in business

BOSTON, March 6, 2008 – Technomad Associates, LLC, a leader in weatherproof outdoor loudspeakers and Turnkey PA systems, today announced it has established a new sales milestone with more than 17,000 loudspeakers shipped worldwide to date. The company, founded in 1995, continues to manufacture all loudspeakers for the commercial pro audio and military/security markets at its Massachusetts facility, where each loudspeaker is bench-built and tested by its small team of craftsmen.

Technomad is proud to contribute to the long-standing tradition of New England manufacturing, said Rodger von Kries, Vice President of Technomad. Our commitment to manufacturing our commercial and military products in the USA ensures the careful craftsmanship of all Technomad loudspeakers is centralized in our Massachusetts facility.

Technomad was the first professional loudspeaker manufacturer to introduce Mil-Spec weatherproof loudspeaker systems with exceptional voice intelligibility and audio quality for highly abusive mobile and installation applications in the commercial and military/security markets. The manufacturing side of the business employs small teams to work on the same loudspeaker from start to finish, with multiple quality checks along the way. This process creates a highly consistent production environment that ultimately reflects the cost and quality of the loudspeakers.

The company’s highly durable loudspeakers provide both clear voice intelligibility and superior musical output, with exceptional, distortion-free audio quality at any volume level.  All Technomad loudspeakers have an IP56 rating from the International Electrotechnical Commission (IEC) for maximum protection against hazardous materials, shock, and dirt and water ingression; and cover a much broader range than competitive loudspeakers, with 120×120 audio dispersion to maintain an even sound through the venue.

Technomad’s range of Turnkey PA systems increased the company’s profile within commercial markets upon introduction for their cost-efficiency, quick set-up and high quality audio output. The complete pre-integrated Turnkey PA packages feature Technomad loudspeakers, a 6-channel audio mixer, 2-channel power amplifier, cables, mounting brackets, a dynamic microphone with cable, and a 6RU rack enclosure. These easy-to-install, user-friendly systems contain everything needed for rugged, high quality outdoor sound.

Club Med Cancun Goes High Tech

Club Med Cancun Goes High Tech

Brian Galante

The 2005 hurricane season will go down as one of the bleakest in history, as the list of named storms became so long that forecasters turned to the Greek alphabet. Hurricane Wilma, the last storm from the traditional alphabet, tore through the Gulf of Mexico early that fall, settling on top of the Yucatan Peninsula and barely moving for 48 hours. After making its exit, some of Mexico’s most famous resort areas, including the city of Cancun, were left battered and faced with a long period of rebuilding.

Club Med Cancun, with its shoreline location, was just one of many resorts that sustained heavy damage from winds, rain and an unrelenting storm surge. The club took the opportunity to rebuild its lighting and sound infrastructure along with much of its resort, favoring high-fidelity audio products and a lighting system that was easy to operate yet technically advanced enough to produce the right atmosphere in each room.

The family resort offers a variety of clubs and restaurants to satiate both kids and adults. The open-air design through much of the resort presented many challenges for the audio integration team, which had to balance the desire for high-end audio throughout the club with the reality of Cancun’s harsh weather environment.

We have done plenty of installations in tough environments, but we have never run into environment as harsh as Cancun, said Bill Weir, Owner of Core Audio. Our challenge in these outdoor areas was to install loudspeakers that could sit in the bright sun and survive the ultraviolet degradation, not to mention the humidity and mineral content in the air the latter of which contributes to rapid corrosion. This all adds up to a highly challenging installation, unlike in any region I’ve experienced.

The Core Audio team, in cooperation with Whump Sound, a Los Angeles based dealer specializing in audio installations, led the systems integration. The central equipment room houses a Digigram digital distribution system that routes audio to eight zones, a combination of indoor and outdoor venues, each with a distinct personality. Technomad loudspeakers were selected for all open-air venues, partially due to the true weatherproof design of the loudspeakers. These venues include a mix of restaurants, bars and entertainment areas plus the valet greeting area in front of the resort.

The indoor areas used two other speaker brands: Altec Lansing for in-ceiling installations where architecturally required, such as in the gymnasium and the late night restaurant Las Cazuelas; and Core Audio’s self-designed loudspeakers for The Soluna, the main indoor dance club. The installations play to the strengths of each speaker, but all share one thing in common according to Weir: outstanding audio quality.

The broad dispersion pattern on both the Technomad and Core Audio loudspeakers require fewer loudspeakers per room. The wider audio dispersion eliminates the phasing issues that are common in large installations, where too many loudspeakers cause an uneven sound in certain areas, or a wishing sound as the patron walks through the sound field.

Many resorts of this size put budget over any other consideration when choosing equipment, and the audio reproduction at the end point is anything but musical, said Weir. Club Med Cancun uses a 24-bit distribution system that plays back high resolution audio files, and that fidelity is well represented in each zone due to the choice of loudspeakers. Core Audio uses a patented subwoofer technology that produces very high audio quality, and we were interested in working with Technomad because we wanted musicality in the outdoor zones. The range of products that can withstand the Cancun environment is very limited, and Technomad meets both the musical and environmental requirements.

The outdoor club environment in tropical locations poses difficult weather related challenges for audio integrators, notably ultraviolet susceptibility to loudspeakers, said David Meyer, Commercial Sales Manager for Technomad. While the weatherproofing aspect is important, it has to sound good regardless of the environment. You can deliver the most rugged, bulletproof speaker, but you don’t have anything if the speaker produces poor audio quality.

Audio distribution is handled over Ethernet, with numerous fiber optic hops across the resort property to extend distribution past the 328-foot limit of the Ether Sound protocol. The eight zones (expandable to 16) are interchangeable, meaning that a music stream can be changed to a different destination point through a simple switching system. Since Club Med Cancun is a family resort, the Digigram network also offers a paging system. Digigram ES220 two-channel transceivers are installed at each end point and can receive two channels of Ether Sound audio from an Ethernet stream. The pages can override the audio stream on the two-channel, mono audio design utilized in most zones.

Music streams can be localized to specific zones, or routed to all eight zones simultaneously. The resort leases a proprietary music servicing software that plays out from a central server in the control room and communicates with the Digigram system for distribution. On-site audio engineers can use Soundforge and Wavelap programs to produce personal CDs in the control room, and can interrupt the automated stream to any zone if they want to play the DJ role.

I’d say the most unique aspect of this project is the routing system, said Diaz. The Digigram system is powerful enough to interact with multiple speaker brands, and gives the on-site operator plenty of flexibility in playback. Even though we operated under a very tight deadline, the entire system came together in a very seamless manner.

The central indoor club is The Soluna, which offers an adult-oriented club environment typical of downtown Cancun. The music in this room is played back through Core Audio loudspeakers, with lighting courtesy of iDesign Productions out of Miami. The Core Audio loudspeakers deliver sound pressure levels of an active nightclub at a higher quality level than is typical due to several design features. A custom subwoofer with a quarter-wave resonant system extends the bass, and special two-way, non metallic coaxial compression drivers smooth the mid and high ranges. The loudspeakers are installed in a traditional four-corner configuration, the ideal setup for the enclosed, air-conditioned room.

The Soluna’s lighting system as set up by iDesign employs a scheduler for two different settings: House and Lounge. The programming is more intricate on the House setting, with more aggressive LEDs and stimulating, rapid lighting changes. The Lounge setting is gentler, with soothing, subtle changes. The programs change slightly by the hour on automated settings, and are barely noticeable to guests. The entire system uses an astronomical clock to calculate the exact time of sunrise and sunset each day.

The lights in the Soluna are very subtle for the first hour and add color and depth as the evening progresses, said Michael Meacham, Owner of iDesign Productions. A typical progression may add teals, magentas and ambers as the programs change. The automated settings also take the staffing situation into account. Since many of the employees work on a six-month term, it’s important they understand how to use the system. So we designed to be as foolproof as possible.

Meacham served as the lead designer and installer, bringing a team to the resort and focusing on key areas one at a time as the rebuilding process moved forward. His team integrated a Color Kinetics control and software system with LEDs as the foundation for the Soluna, with installations inside the bar and within soffits in the ceiling. Color Kinetics LEDs were also installed in an outdoor entertainment area that serves multiple purposes .Martin Mac 250 Kryptons and Washes were added throughout the Soluna for articulation.

The outdoor entertainment area, known as The Chispa, offers a movie theater and a performance area with an exceptional A/V and lighting system. The central kiosk area is peppered with palm trees that are lit using Color Kinetics color blasts. The LED fixtures for each palm tree are automated using a Martin Light Jockey control system, with 220 volt power lines providing juice to each palm tree. Like the Soluna, the lighting for this zone is customized to match the event, and can be manually operated on theme nights using a small 8-button switcher. Martin 250 Kryptons and Washes were also installed in the theater area.

We programmed white, stoic lighting for the palm trees on certain nights, but there are other theme nights that benefit from more intensive lighting, said Meacham. This outdoor area features an island where the resort hosts a circus that includes a giant trapeze. We took more creative liberties here: The colors move quicker, and the intention is to recreate the feeling of approaching a carnival. Whether you are inside having dinner, hanging out at the Chispa kiosk or having a drink at the pool bar, these lights are designed to invoke emotion as you look toward the island and see this giant, gorgeous structure lighting up the atmosphere.

The Chispa movie theater is perhaps the most unique aspect of the resort, and according to Weir, a one-of-its-kind system. The integration team painted one side of a three-story hotel building on the resort with retro-reflective, high-gain paint. Guests can sit on the beach or on bench seating in the pool area to watch movies projected onto the building.

A triple DLP 5000 HD projector, mounted in a protective cage on the beach, projects a 30-foot wide, 15-foot tall 16:9 aspect ratio image. Guests can take advantage of a Sennheiser RF headphone system with a broadcast range of 300 feet to watch the movie undisturbed, while those who want to enjoy the ambience can do so without the audio dominating the atmosphere.

DJs and performance groups can also take advantage of this outdoor entertainment area. A pair of Technomad Berlin loudspeakers was purchased for mobile events, and plug in to rack systems on the performance stage. The dedicated control room features an Allen & Heath GL2800 front of house mixer and processing equipment to assist with these live events.

The remaining room-to-room breakdown of Technomad loudspeakers include: The Pergola, a beach bar that features four Noho loudspeakers hung 9 feet above the crowd and two Chicago 15 subwoofers at two corners along the baseboards; eight Vernals in The Chispa and Las Velas, the pool bar; and Noho and Vernal loudspeakers in the valet area, which play back low volume music as guests enter the resort. Crown DSI series amplifiers are used to power the audio in each of these zones, offering full parametric EQ, crossover functions and basic signal processing. (A Rane RPM88 DSP is used to power the Core Audio loudspeakers in the Soluna.)

The Berlins were specifically chosen for mobile events because they are high quality, full range portable loudspeakers that can be used anywhere on the resort at a moment’s notice, said Weir. They offer a full range of sound with excellent bass response and a very nice tonal quality that is ideal for DJ sets. In the Pergola, the Nohos produce enough sound pressure levels at 1 a.m. so that people who want it loud can turn up the volume, but still produce a full, pleasing sound at lower volumes. This was the same idea we had for the Vernal 15 installation in the pollapa, with a higher emphasis on producing clearly audible sound at low levels for conversational situations.

All power and electricity issues were resolved in the early stages, although there were plenty of challenges. Meacham had an easier go of it with the lighting system.LED technology requires very little power, which makes our job that much easier. It is entirely possible that one of the four Mac 250 lights in the main bar took more power than the entire LED display in that zone, he said.

The audio installation proved far more complex, from the cleanliness of the power coming into the resort to more common grounding issues. We had to resolve numerable electrical engineering issues ahead of time, from improper load balancing in the main three-phase transformer to adding clean technical earth at multiple entrance points, said Weir. We removed a lot of the audio on common phases with large inductive loads, like refrigerator compressors. We also custom built resident filters with some of the power lines to filter out harmonics generated from motor noise in the AC system. It was pretty much a nightmare situation that required a lot of troubleshooting.

The electricity issues proved to be the only real undesirable aspect of the project, and the end result has been pleasing to everyone involved.

Contractors may view this as a standard design in terms of audio and lighting, and it is similar to what you see today in theme parks and large corporate installations, said Diaz. But the resort community seems ready to catch up.
