Technomad Loudspeakers Bring Clear Game Day Audio to High Schools and Colleges

AVX Northwest completes two Technomad athletic installations in Washington that brave the rainy elements outdoors and also provide crystal clear audio indoors

BOSTON, February 17, 2009 Technomad LLC, a leader in weatherproof loudspeakers and audio systems since 1995, announces that AVX Northwest, an AV equipment dealer, consultant and installer based in Centralia, Washington, has completed two Technomad Turnkey PA school installations in the Pacific Northwest.The Technomad installations, at Saint Martin’s University of Lacey, Washington and Kalama High School of Kamala, Washington, provide substantial athletic sound system upgrades on the campuses indoors as well as outdoors.

“The reliability and durability of Technomad loudspeakers outdoors is renowned because of their weatherproof design, and the voice projection and musical quality is also very much appreciated in this industry,” said Mark Abbott, Founder of AVX Northwest. “That audio quality and reliability translates phenomenally indoors, especially in gymnasiums for live sports, concerts and other events. Indoors, we typically hang the loudspeakers on ceiling rafters and direct the loudspeakers so that there is an even pattern coverage across 360 degrees.The handoff from one loudspeaker to the next is virtually unnoticeable.”

Technomad Turnkey PA Systems typically include between two and four Technomad weatherproof loudspeakers, a 6RU signal processing rack featuring an amplifier, mixer and CD player, a dynamic microphone, and all associated cables and connectors to form a complete PA solution.Both campuses received Technomad Turnkey PA systems for various outdoor and indoor venues.Saint Martin’s University is sharing the signal processing rack between three venues, transporting it between a baseball field and fast-pitch softball field.

Abbott installed seven Technomad Paris 616 loudspeakers between the two fields: four for baseball, and three for fast-pitch softball.He installed the loudspeakers behind the backstops and along the first and third base lines to ensure clear coverage to all areas.Technomad’s new loudspeaker yokes were used to hang and support the loudspeakers, providing plenty of flexibility to shield the loudspeakers from line drives and position them for the best possible audio directivity.Abbott ran wiring to a lockable, vandal-proof box by the scorekeeping booth, where an operator can plug in and turn on the system for immediate operation.

Kalama High School purchased two fixed Turnkey PA systems for its multi-purpose outdoor stadium and gymnasium, where basketball and volleyball games and school concerts are held.According to Abbott, the multi-purpose outdoor stadium for football, soccer and track previously relied on a horn system that provided poor sound quality and fell into disrepair.Abbott installed four Nohos on the back rafters and wired the system so that the Turnkey PA rack is simply connected to pre-configured cable runs that descend through the press box ceiling.The result is a reliable, plug-and-play installation.

“The projection of the Technomads gives you more than any horn system could offer for voice, but the bigger difference is the bass response and music quality,” said Abbott.“Most of the announcers are male, and horns cannot precisely reproduce the male voice because of the lack of lower end.And bass reproduction is very essential for today’s music, which is especially important for football games and practices.”

According to Bruce Rader, school board president at Kalama High School, the Technomad system was part of a larger upgrade to the outdoor stadium that also involved a new turf and a paint job.“The old horn system sounded horrible; cheerleaders wanted to play music through it and it didn’t work.The four Nohos reproduce music very well and cover the entire stadium, from the home to visitor stands and across the field to each end zone,” he said.“Inside, we were using 20-year old loudspeakers, and Mark also recommended four Nohos.We thought that might be overkill, but the sound is loud and clear without coming across as overpowering.They sound incredible.”

Abbott added that the weatherproof aspect is highly important to withstand the consistent rain and dampness of the Pacific Northwest region, and the occasional weather-related curve ball.“This winter, we have had record amounts of snowfall,” he said.“To have a loudspeaker I don’t have to worry about out in the elements says it all.

“But the simplicity of this Turnkey PA System is that Technomad has done all the work,” added Abbott.“They wire the amplifier, mixer and take care of all the cabling in advance.Everything is self-contained and it is an excellent system for schools and colleges that are on a limited budget but want the versatility that comes with being on the go and supporting multiple events.”

Technomad Loudspeakers Provide Game Day Audio Coverage at Jamsil Baseball Stadium

Technomad  announced that C.I.C. Electronics, a Technomad dealer located in South Korea, installed a variety of Technomad weatherproof loudspeakers throughout Jamsil Baseball Stadium in Seoul.  C.I.C. Electronics, a global supplier of professional audio and public address systems selected Technomad loudspeakers for their outstanding audio quality and projection, weatherproof design, and durability.
Jamsil Baseball Stadium, built in 1982, seats 30,265 people and is home to both the Doosan Bears and LG Twins, both professional teams of the KBO Baseball League.  C.I.C. installed Technomad Berlin, Paris616 and Vernal-15 loudspeakers in various areas depending on the amount of power required for each specific location.  The Technomad Berlin, part of the company’s AS Series of loudspeakers, is the largest of the three models.  TheBerlin offers unparalleled projection, fidelity, and power to disperse intelligible voice and music throughout the stadium while maintaining an even pattern.
 
 
The Technomad Paris 616 and Vernal-15 models, part of the company’s MP Series of loudspeakers, offer more compact designs for all-environment installations, distributed systems, and sound reinforcement applications. Like the Berlin, both the Paris and Vernal offer unmatched fidelity as well as very broad dispersion to ensure that clear audio is hitting the most difficult-to-reach areas within the stadium.
 
Jamsil Baseball Stadium comprises part of the Jamsil Sports Complex along with nearby Seoul Olympic Stadium, and was host to baseball events during the 1988 Seoul Olympic Games.
 

Technomad Introduces New Products: High-Q Versions of Berlin Loudspeakers

Narrower dispersion pattern gives more options to Technomad customers for controlled output patterns in venues of all sizes

BOSTON, December 3, 2008 Technomad Associates, LLC, a leader in weatherproof loudspeakers and audio systems since 1995, will begin shipping the next generation of its popular Berlin weatherproof outdoor loudspeakers this month.The two new Technomad Berlin loudspeaker models offer a narrower dispersion pattern than previous generations.These new pattern control configurations are ideal for design engineers, contractors and consultants seeking a more controlled output pattern while retaining the high-audio quality and rugged design that are benchmarks of all Technomad loudspeakers.

 

The new Berlin loudspeaker models offer constant directivity to maintain a consistent dispersion pattern of 60×40 or 90×40 dependent on the needs of the venue.The two options give systems designers more flexibility when working in tightly controlled acoustic environments or in outdoor installations where long distance projection is required.

“Technomad customers have often requested a loudspeaker design that is ideal for targeting specific parts of a venue as opposed to blanketing a very wide area. The new Berlin configurations achieve this without sacrificing the qualities and features of the Technomad brand,” said Rodger Von Kries, vice president of Technomad. “The narrower dispersion allows our products to be used in arenas and stadiums where installers want more pattern control to target sound in each specific area. They are also ideal in smaller outdoor venues where long audio throw is desired, such as a high school football field, while ensuring that the audio is localized to the audience and not spilling outside of the venue.”

 

The latest generation of the Berlin loudspeaker reflects the company’s philosophy of refining its established range of loudspeakers instead of continually introducing new loudspeaker products to the market. For optimal flexibility, design engineers and contractors can plan Technomad installations featuring both the new narrower dispersion Berlin models and other Technomad loudspeakers with wider dispersion patterns.

“The ability to offer a full range of loudspeakers with various dispersion patterns is ideal for contractors and design engineers since a one-size-fits-all approach is a rare situation in larger venues,” said von Kries. “Our wide dispersion products, including the Technomad Vernal 15 and Noho C loudspeakers, give our customers the wide variety of options they need for professional installations. Every situation is unique dependent on the total coverage area and the amount of control required.”

Technomad Berlin loudspeakers are part of the company’s AS Series of IP56 weatherproof loudspeakers, offering unmatched controlled projection, fidelity and power for the most demanding fixed installations and mobile applications. Both the 60×40 and 90×40 Berlin loudspeakers come standard with passive network and bi-amp configurations, and are available in 8-Ohm and 70-volt versions.

Technomad Loudspeakers Pass GLL Certification at NWAA Labs

GLL testing provides detailed measurements of loudspeaker data to allow more accurate positioning and simulation of loudspeakers in various venues and environments

BOSTON, August 18, 2008 – Technomad Associates, LLC, a leader in weatherproof loudspeakers and audio systems since 1995, has upgraded to the GLL (Generic Loudspeaker Library) format to measure and present its loudspeaker design specifications to the pro audio industry.  GLL format data gives Technomad design engineers, consultants and contractors more options in positioning and simulating loudspeakers in large sports, entertainment and other venues that require array or clustered installations. Technomad is one of several loudspeaker manufacturers that encompass the first wave of GLL supporters in the pro audio industry.

GLL is a new standard for measuring and storing loudspeaker performance data that is now part of the EASE software suite, which provides simulated creations of a room’s 3D acoustic model and sound system. The GLL format provides highly accurate technical detail about the loudspeaker design and driver output so consultants and design engineers can more accurately position loudspeakers in various environments compared to simulated point source formats such as SPK or CLF.

Technomad recently visited NWAA Labs, an independent, vendor-neutral laboratory that provides uniform product testing of loudspeakers. Led by Ron Sauro, Owner and Chief Scientist of NWAA Labs, Technomad’s range of IP56-rated weatherproof loudspeakers underwent GLL testing for the first time. The GLL testing system created by NWAA Labs uses a system of accurately-calibrated microphones positioned every five degrees in a four-meter arc to collect data in a highly consistent manner, with the loudspeakers immersed in an anechoic chamber to eliminate reflected acoustic artifacts. The process more accurately collects loudspeaker data than the traditional way of physically moving the position of a single microphone to record measurements at different angles and is much faster.

The tests officially quantify Technomad loudspeakers as GLL-ready, with results and measurements available for download and usage with the new EASE 4.2 software program.


NWAA Labs in Santa Clarita, Calif., is the leading site for GLL testing and certification of professional loudspeakers


“GLL testing is a critical step forward in accurate data collection for loudspeaker design engineers, particularly those specifying a venue that will include clusters of multiple loudspeakers,” said Sauro. “Engineers and consultants who download the GLL files can more accurately predict what will happen in a room or facility when multiple cabinets are used, and also predict and better understand the interaction between all the cabinets and drivers in the loudspeakers. The GLL format provides a very accurate resolution of phase that is superior to how we previously measured and presented data.”

Sauro added that manufacturers like Technomad benefit from GLL testing through physically assembling loudspeakers in a “virtual reality” or simulated environment, measuring the drivers without crossovers or digital signal processing, and making design changes that are instantly noticed. This improves the speed and accuracy of developing the loudspeaker.

“Technomad contractors have always relied on the power, durability, weatherproofing and high audio quality of our loudspeakers,” said Rodger von Kries, vice president of Technomad. “Through testing at NWAA Labs we have been able to generate GLL files that provide consultants and design engineers with the most accurate loudspeakers measurements possible. This highly accurate data provides design information that gives contractors new and exciting options to use Technomad loudspeakers in larger venues. By presenting these measurements in the GLL format, we can more accurately represent this data to the pro audio industry at large.”

A former NASA engineer and scientist, Sauro now heads up NWAA Labs, a Santa Clarita, Calif.–based lab for testing loudspeakers and materials for the audio industry Among other things, the lab tests loudspeakers for conformance to the Generic Loudspeaker Library specification, which was introduced at the AES convention in New York in October 2006.

PRO AV: Tell us a little about NWAA Labs.

SAURO: NWAA Labs was founded to fulfill a long-standing, but unrealized industry requirement for independent, standardized loudspeaker and acoustic materials testing. I was able to adapt the array I designed at NASA for magnetic data acquisition for use in gathering sound data at NWAA Labs. This design allows for an exponential increase in the rate of data acquisition, reducing the time involved from many hours, to often less than 40 minutes, thus minimizing the environmental variations that hamper accurate measurement, particularly phase measurements.

PRO AV: What is the Generic Loudspeaker Library?

SAURO: The Generic Loudspeaker Library is a method of inputting, calculating, and displaying complex speaker directivity data. It’s accomplished by measuring individual drivers, in place, and then mathematically integrating these balloons with crossover transfer functions. The data is gathered and stored using impulse responses and can be geometrically combined to do what point-source information cannot do. Its first use was in the EASE 4.2 program, but has been designed as a generic data source for use by the entire industry. It provides a large source of information in a very small storage footprint.

PRO AV: What does GLL testing say about a loudspeaker and how it might perform in the real world?

SAURO: It is especially useful for the construction and simulation of line arrays and complex cluster arrangements in order to predict lobing and other acoustic results more accurately. In other words, GLLs can be used by simulation programs to accurately predict real-world performance of complex and variable configurations of loudspeaker boxes and arrays.

PRO AV: How can AV pros use GLL results and GLL files?

SAURO: Consultants can take advantage of independent testing to confirm equivalent performance between loudspeaker boxes created by different manufacturers. This is useful when specifying a system and then having many contractors bidding with “equivalent” speaker boxes. Comparing GLL measurements helps remove subject marketing claims from what should be—and now can be—an objective process. This also helps contracting personnel to meet system performance criteria.

PRO AV: How has industry adoption been so far?

SAURO: We are receiving more and more requests from consultants and contractors for GLL data and more than a dozen manufacturers have adopted the GLL format. (Technomad Associates of Boston most recently received GLL certification from NWAA Labs for its IP56-rated weatherproof loudspeakers.)

ShedWerk’s Installs Sound Systems by the Seashore

Few people have visited Los Angeles without stopping at one of the most famous restaurants in the country; Gladstone’s Malibu. Gladstone’s originally opened in 1972 as a small restaurant in nearby Santa Monica Canyon and moved in 1982 to its current location, on the beautiful shores of the Pacific Ocean on the Pacific Coast Highway. Gladstone’s is one of the top ten largest grossing restaurants in the United States and the single largest, as well as the top grossing, restaurant on the entire west coast. Gladstone’s, open 365 days a year, accommodates 750 people at a time, welcomes more than a million people each year, and serves more live Maine lobster than any other restaurant in Southern California. It has also just become even bigger and better after a $3 million renovation.

When you approach the entrance of Gladstone’s Malibu you immediately get a sense of a fun, casual, unpretentious, carnival atmosphere. As you enter the restaurant, there is a “Wall of Fame” where patrons can view a collection of celebrity photos taken at Gladstone’s over the years. A new bar area has been added to create the feeling of a true 1950s beach bar. The original dining area has been restored and boasts the largest collection of historical photos of the bay and local area. The dining experience in the new Outrigger Dining room is enhanced by the lofty 18-foot ceilings, 12-foot high windows, and the best unobstructed vista of the Pacific Ocean on the coast. There is also a back dining area called the “Movie Room,” which is a more intimate space, decorated with photos of movies that were made in the Malibu area starting with the original Inceville Studios of the early 1900’s, located where Gladstone’s now sits. The outdoor patio has an uninterrupted ocean view and a festive “boardwalk” feeling. The subtle wash of deck lighting on the water enhances the Oceanside dining experience.

Gladstone’s has an expanded kitchen, bar, and a new building in front of the restaurant to service hungry diners on the popular front patio. The new $3/4 million Fish Market building tucks in behind the PCH deck with its own outside kitchen. With the outside kitchen, Gladstone’s staff can assign seating and provide quicker service to the deck. There are new bars and the fish cutting room, with live lobster and crab tanks, is replete with a large window where fresh fish cutting is exhibited.

SHEDWERKS:

“ShedWerks, as a business, essentially keeps my chops up,” Owner Bruce Maddocks quips. “I love the art of audio and designing new systems, regardless if they are multi-million dollar studios or high-quality sound systems in prestige landmarks, like Gladstone’s.” Based in Woodland Hills, California, ShedWerks, established in 1992, specializes in commercial and residential sound reinforcement system design, consultation, remodel, rebuild, original fabrication, and installation. Bruce also maintains his chops from his full-time gig as chief engineer of Capitol Studios in Hollywood, overseeing all the technical operations for the recording and mastering studios.

Capitol, Bruce points out, is constantly in the process of upgrading existing studios, or adding new studios, in the Capitol Tower every eight months. Bruce states, “A lot of it is remodeling and bringing the technology of the existing facilities into the new millennium. Since I do a lot of design work for DVD production and surround sound, I’m designing and redesigning facilities to deal with multi channel audio.”

Gladstone’s previous sound system had been in service, states Bruce, “I believe, probably about 17-odd years.” Continuing, Bruce points out, “Initially, when I went to do the site survey, I said, ‘Okay, let me see what I can reuse to try to keep a handle on the cost.’ First off, the process of the construction had already begun and a lot of the existing wiring just got cut, therefore, since no diagrams existed, I couldn’t physically trace the wires.”

As Bruce began to look at all the remaining components, like many sound systems, it appeared it had started out fairly small. Bruce observed, “Through the years different pieces got added to it, but not in a very cohesive manner. There were bits and pieces here, there, some stuff kind of tacked on in between.” Bruce quickly realized the restaurant had to install a completely new system. There was literally nothing out of the existing system to salvage, “except for the Yamaha five disc carousel CD player, and the DMX satellite music receiver,” Bruce adds.

Bids for the new sound system went out about midpoint in the construction. The Restaurant had put out bids to several vendors, and a lot of the proposals that came back, states Bruce, “Were for real typical, straightforward, generic restaurant sound systems. They were all pretty mundane, a lot of ceiling loudspeakers, with no real imagination put into any of the bids.”

One of the most important things Bruce did when putting the bid together was, “I spoke to the principals of the restaurant to find out what they wanted!” he chuckles. “Based upon the other bids that came in, it didn’t look as if any of the other bidders did that.” Continuing, Bruce says, “Gladstone’s wanted something that was a lot better than what they previously had installed. I believe the one thing that impressed them was my experience in designing studios, loudspeakers, and sound systems for studios and mastering facilities, as well as my sound design experience. I advised them I could incorporate my unique experience into a sound system design which would give them maximum impact, really rock at a fairly moderate level, and still operate as background. They keyed into coherency, articulation, intelligibility and the ability to cut through without being obtrusive. This intrigued them a lot.”

The dollar amounts on even two bids, for the most mundane and ‘generic sound systems’ have a tendency to fluctuate dramatically. Even though Gladstone’s was investing three million dollars into expanding and upgrading this landmark restaurant, money was an object. Bruce states, “It’s fairly safe to say that any of the sound system bids were probably the smallest dollar amount expenditure for the new construction. Even though I had management talked-up on a studio quality, high-fidelity system, every aspect of the construction was under financial scrutiny.”

ShedWerks entered the project midway through construction, and to make matters worse, the restaurant was still open for business during the entire rebuild period. To stay out of the way, ShedWerks had to pre-assemble and test all the racks in the shop, and then deliver and work on an off-hours schedule. The installation was overseen by Bruce, with Eric Malin from Malin construction taking on all of the mechanical installation work. Sallie Arnold from “Get Wired” did all of the wiring interface work on the project. A lot of the install took place mostly after 1 or 2 a.m. and the three person crew would work straight through until almost 4 o’clock in the afternoon, all the while trying to remain unobtrusive to the other construction trades.

THE GEAR: LOUDSPEAKERS

Working from the loudspeakers backward, Bruce researched loudspeakers based upon size, output, and fidelity. While researching replacement loudspeakers for an entirely different job – the echo chambers at Capitol Studios, which are large, damp, dank, musty, and occasionally moisture-laden underground rooms – Bruce came across the Technomad WeatherTech Vienna 16 loudspeakers. “We use these rooms in the recording process for their natural reverberation characteristics. But, the room environment wrecks havoc on loudspeakers. Totally unrelated to what I had going on with Gladstone’s, I got a hold of the Technomad Vienna 16 loudspeakers and even before I could install them in the echo chamber, I was blown away by the sound quality.”

Since Bruce had been evaluating low-profile loudspeakers for Gladstone’s, he decided to take a listen to Technomad’s new Vernal 15; a 60 watt powerhouse featuring a 5″ polymer mid/bass driver under a 1″ diameter ceramic high-frequency compression driver, on a 90° X 90° horn. “The Technomad Vernal is the speaker I was looking for,” states Bruce. “As equally impressive as the horn is at cutting through the background noise generated by 750 people, as well as the wind and the sound of the surf, the low-end on the Technomad Vernal 15 is very pronounced and detailed from a cabinet that is only nine by six by six inches. The Technomad Vernal 15 was going to be the primary loudspeaker of the overall sound system.”

Twenty Technomad Vernal 15, 70-volt transformer version loudspeakers were utilized for the main dining and Movie Room a private function dining area. Bruce states, “I was able to get the best overall coverage by installing the Technomad Vernals along the perimeter of the room and the focusing the dispersion pattern of the Vernals into every alternate bay within the main dining room. That way, I was able to get full coverage without any drop-outs.”

The bar and two dining areas off the main dining room were also fitted with nine suspended Sound Tube RS50 loudspeakers. The Omni-directional pattern provided large areas of coverage from the high ceilings and their very low profile did not impact the cosmetically clean decor of the rooms. The Outrigger room was also fitted with three RS50 loudspeakers, suspended eight feet down from the twenty foot plus ceilings.

“In the Movie Room it was pretty straightforward installation of six Technomad Vernals,” Bruce states. Three Technomad Vernal 15 loudspeakers are on the opposite walls, at the eight-foot ceiling height. “Since the Movie Room is a party or private function area, I put a high concentration of loudspeakers in there on a separate zone,” Bruce continues. “This room can produce a fairly high impact party atmosphere that is completely separated from the rest of the restaurant.”

Keeping costs down, Bruce did not add any subwoofers to the dining rooms. “I found that by utilizing a lot of the boundary effect, proximity to walls and ceilings, it wasn’t really necessary to add any subs. Since it is a 70-volt system, my overall low-end is limited by nature of the transformers and the amps, but I am very impressed that the Technomad Vernal 15 loudspeakers produce an incredible amount of low-end from such a small cabinet.”

But the lack of subwoofers was not a detriment to the overall sound quality of the system. “I use very selective compression and equalization techniques that I’ve picked up through the process of recording and mixing music. So, I just apply those practices into the system and I can actually make all of the music cut through without it being overbearing or obtrusive.”

For the exterior Ocean Deck area, Bruce installed two Technomad Vernal 15 loudspeakers and three Sound Tube Storm Tech ‘Sea foam Green’ loudspeakers in ‘Sea foam Green’. States Bruce, “The ‘Sea foam Green’ finish matches the new awning and exterior finishes.” Due to the large open area of the on-the-water deck, the three Omni-directional loudspeakers were mounted to the existing poles that run down the middle of the deck, simplifying the ‘non-directionality critical’ aspect of the installation. The two exterior Technomad Vernal 15 loudspeakers were installed firing out onto the deck area, filling in walkways and outdoor waiting areas.

THE RACK

A wall mounted, locking 27 rack spaces, ZERO steel case provides a home for all of the rack-mount equipment. The Desk Doctor Controller/Interface was mounted at the top of the rack at eye level, as the only adjustments that would be needed on a daily basis would be the selection of program sources and their associated zone levels. Bruce installed the existing Yamaha 5 CD carousel player below the Desk Doctor Controller. The CD player would be used typically for the Movie Room to provide requested or even guest-provided music. Channel selection on the DMX satellite receiver, installed below the CD player, is made by either the front panel selector or by remote control. The ARX Systems Quadcomp II, four two-channel ART equalizers, the Rane MA-6 and the QSC amp rounds out rack. One rack space is left open between the Rane and QSC power amps as ventilation space. A 2 rack space AC Surge protector and outlet distributors were mounted in the bottom of the rack.

A plywood panel was affixed to the rear inside of the rack to strengthen the wall mounting, as well as facilitated the mounting of the 70V 100 watt output transformers for the RANE amp. All of the equipment wiring interface was completed in ShedWerks’ Woodland Hills shop before delivery to the location. This allowed Bruce and staff to thoroughly test the system dial in some rough compression and equalization settings by simulating some of the install. Once on site the rack was wall mounted and the speaker wire/paging interface was connected, fine tuning of equalization, paging balance and compression was quickly completed. Once all the electronic setting was finalized, security covers were installed on various pieces of signal processing equipment to prevent prying hands from resetting equipment.

THE POWER AND FRONT END

Bruce states, “I’ve set-up the restaurant into eight separate zones and for that I went with two amplifiers. The first amplifier is the new QSC CX series 302V amplifier. One channel of the QSC 302V is running the Main dining room and then the other channel is running the Ocean deck. The second amplifier is the RANE MA6S six-channel amplifier.”

Bruce is responsible for the design of the system’s custom-controller paging/interface with fabrication of the unit by Bruce Millett of Burbank-based, The Deck Doctor. “It’s a fairly interesting interface,” Bruce states. “I’m used to working in a balanced plus-four audio environment. I like to have the additional operating level as well as the common mode rejection you receive when working balanced. The first stage of the paging interface is eight minus 10 unbalanced inputs. You get your stereo outputs from the Yamaha multi-disc CD player or DMX satellite receiver, and it converts the eight unbalanced minus 10 feeds into it into four mono balanced outputs. Working with balanced audio and a proper grounding scheme really reduces the headaches associated with potential ground loops. The interface box produces level control for the four individual sources, which is then sent to the compressors. The processed signals are returned to the controller were they are routed to the source selector on the eight individual zones. Every single zone can then select whatever it wants to listen to, and then each zone has its own level control. The output of each zone is then sent to an equalizer and then to the power amps.”

Bruce continues, “I constructed a two-area paging system: one for inside the restaurant and one at the paging station for the outside deck areas of the restaurant. The user can select between any of the eight zones or do an ‘all zone’ call. Another aspect of the system was to insert all of the paging after the level control for each individual zone. A 15 dB program ‘duck’ level is activated with each page. That way I can have consistent paging levels throughout all of the zones no matter how they set the music level.”

“One of the things that happened previously in the restaurant was that they were using auto tap transformers,” Bruce recollects. “So in the bar area, if they wanted to listen to the television, they would turn the music loudspeakers down. When a page was announced, you never heard it in the bar, and that’s the area where everybody’s waiting to be seated. That didn’t quite work, since whenever the sound system was turned down, the guests were missing their table calls. Now, by using a paging interface that works after all of the individual level controls, no matter where they set the music, paging, now, always comes through.”

For “people protection” Bruce utilized an ARX Systems single-rack space, four-channel Quadcomp II limiter/compressor. Bruce states, “It’s pretty straightforward. Very clean, very fast, and very simple to use. I prefer this unit over others because it has four compressor/limiters in a single rack and in this job; rack space was at a premium.” Also installed were four of the ART Model 341 equalizers. “So,” Bruce states, “I’m able to do just a little bit of equalization and balance in each one of the zones.”

Bruce notes, “Obviously, since Gladstone’s is right on the Pacific Ocean, the environment is rather harsh. You’re looking at sea spray, wind, fog, rain, it’s a highly corrosive environment for electronics, I settled on the Technomad Vernal 15s, primarily because they were the best sounding speaker for the application. Also, out of all the loudspeakers I was evaluating for the interior areas, the clean cosmetic design and low profile of the Vernal best suited the design. Granted, the interior dining area, even with all the windows open, is not as harsh of an environment as the Ocean Deck, so I really had my options opened for the loudspeakers.”

Reflecting on his accomplishment, Bruce states, “The sound system is really even. One of the things I wanted to accomplish was to make it so you could walk from the deck entrance of the restaurant, to the bar, all through the dining rooms, and not hit a dead zone. It took a lot of work to get it right, but by doing the walk-through, and running back and forth, not to mention a lot of folks with good ears and walkie-talkies, we were able to get the whole system very even so there’s no radical changes, even as you move from zone to zone to zone.”
