Extron Introduces Six Input, Four Output Audio Expansion Processor with AEC and Dante

Extron Electronics is pleased to introduce the AXP 64 C AT, an audio expansion processor with six mic/line inputs and four line outputs for remote connectivity to a Dante™-enabled DMP 128 audio system. It is used to place six mic/line sources onto a Dante audio network, and route any four Dante channels from the network to an amplifier or other destination. The AXP 64 C AT features Extron ProDSP with gain, filtering, and dynamics processing for all inputs and outputs. Four of the inputs also include AEC, 48 volt phantom power, and control ports. FlexInputs offer the additional capability to process Dante channels in place of the first four local inputs. A single Ethernet cable from one AXP 64 C AT, or several linked units, to a central equipment rack greatly reduces the effort and expense of pulling one cable for each endpoint. more

Entertainment Quality Audio System for New Debrecen Stadium


Interton Ltd has designed and installed a Community loudspeaker sound system for the new Nagyerdei Stadion in Debrecen, Hungary. An all-seated football stadium, Nagyerdei has a 20,340 capacity, making it the third largest capacity Hungarian football stadium and the second largest Hungarian League stadium.

Home to the Debreceni Vasutas Sport Club, Nagyerdei Stadion was opened on 1 May 2014 and the first official match was played between Debrecen and Újpest, which ended with a 3-1 victory for the host team. As well as hosting Debreceni VSC games, the stadium will host matches for the Hungarian national football team. The ground also incorporates conference and banqueting suites and has a club shop selling Debrecen merchandise.

Zoltán Horváth, chief engineer of Interton Ltd, explained the basis for the system design, “Community loudspeakers are our first choice for stadium systems, and we have completed many successful projects with R SERIES. The brief for Nagyerdei, in addition to good speech intelligibility, was for discrete styling and high quality music, so the obvious choice was the weather-resistant version of the iHP-1596 from the iBOX SERIES, which provided the power, wide frequency response and aesthetics the client wanted. An EASE simulation was carried out to confirm the design would meet the required criteria.”

The audio system network is provided by a Q-SYS system, with one Core250i and the required number of I/O Frames. The main arena sound system uses four I/O Frames and twenty-eight PLX3102 amplifiers, located in four rack rooms. These amplifiers drive fifty-three Community iHP-1596WR loudspeakers, mounted below the outside edge of the canopy and providing sound to the 360-degree grandstand and to the playing field. The iHP-1596WR is a premium quality large-format 15-inch full-range loudspeaker system with 90 x 60 degree coverage. “The results are impressive,” comments Horváth. “It’s a really nice sounding system with great SPL to inform and entertain a capacity crowd.”

In addition to the main arena PA, Interton designed and installed the audio systems for the venue’s main buildings and studio and also supplied a mobile conference system. Interton additionally installed the scoreboards and the perimeter display, the video distribution system and more than 100 LCD displays. Audio and video distribution are Ethernet based using the stadium’s LAN.

An inauguration ceremony was held for the opening of Nagyerdei Stadion by Hungarian Prime Minister, Viktor Orbán. After sanctification by leaders of both the Roman Catholic Church and the Greek Catholic Church, singers including Lou Bega, Viktor Király, Ildikó Kersztes, Gigi Radić and Erika Miklósa entertained the audience at the celebration.

Diggerland Offers Great Fun with Great Sound

Unique Attraction Features Construction Site Theme and Community Loudspeaker System

Spellcaster’s Mike Shafer says “looking at the vast areas I had to cover outdoors, I immediately thought of R Series.” He chose R.15COAX loudspeakers for the outdoor short-throw, fill and walkway areas and R.35-3896 three-way loudspeakers for the long-throw applications.

Diggerland USA’s indoor spaces have dropped ceilings with very little space between the ceiling and the roof deck. Shafer used Community’s D4LP four-inch, low-profile ceiling loudspeakers which fit in the restricted space and left room for wiring. For the covered open-area spaces such as the games arcade, he used Community’s DP6 pendant loudspeakers which brought the sound down below the ceiling beams and vibration isolated the loudspeakers from the metal roof. The overall park loudspeaker system is a 70-volt distributed design that used over 12,000 feet of speaker cable.

Spellcaster used Ashly amplifiers and an Ashly NE24.24M DSP to manage the park audio systems. They added a park-wide Wi-Fi system that allows Diggerland USA technical personnel to adjust the audio systems from any point in the park with an iPad. Spellcaster also integrated the audio system with the park’s CCTV cameras and security systems.

Diggerland USA plays music and advertising messages over their audio system with a live DJ for special events. Paging is available from any park telephone and Shure wireless mics are available for parties and other special events. Spellcaster’s Shafer says, “the park’s audio systems are everything we expected. The music sounds great and the voice paging is loud and clear.”

Delicate Teams With Martin Audio MLA For Latin Radio Concert

Delicate Productions recently provided a Martin Audio MLA system for the Reventon Super Estrella 2014 concert at the Staples Arena in Los Angeles.

Put on by L.A.’s leading Latin FM radio station La Super Estrella 107.1, the show featured an impressive lineup of artists including La Santa Cecilia, La Union, Fobia, Roco Pachukote, Bunbury, La Ley, Caifanes and Victimas for a capacity crowd of over 18,000.

Asked about the show, Delicate Production Manager Meegan Holmes explained, “Our challenge with any concert style event in an arena is integrating our PA hangs with the lighting truss and the flown LED elements. We worked closely with the LED vendor Global Trends to ensure the best positioning of the PA versus the LED wall. The walls were all solid, so our concern was areas of the audience that would be affected in terms of being able to hear the audio. We took care to lay out our PA points so we could get past the LED but still not block the view of the screen.

“Staples Center is taller than the average arena,” Meegan continued. “The back wall has decorative metal above the top level of seating. The MLA’s versatility and output control enabled us to get to the last row without hitting that highly reflective metal.”

The system Delicate rigged for the show included 28 Martin Audio MLA and 4 MLD (downfill) for the main hangs; 16 MLA Compact for outer fills; 16 MLA Mini under 4 MSX power plant/subwoofers for sidefills, and 12 MLX subs. Other elements included Avid Profile consoles for Front of House, a DiGiCo SD11 as production console and a Yamaha DME matrix for system control.

In addition to Holmes, the Delicate crew was made up of Brennan Houser (System Engineer), Craig Robertson and Tony Luna (FOH Technicians), George Squiers and Mark Ramos (Monitor Technicians), and Russ Cunningham and Billy Flores (Stage Technicians).

Asked about reactions to the sound system, Meegan explained, “Each band in the show seemed a little louder than the previous and the PA kept up without issue. All eight engineers had fun mixing on the system, which resulted in great sounding shows. They all commented on how they were able to get so much power from so few MLX subs and how efficient they are.

“Our client came to me after the show amazed at how the rig sounded the same everywhere, how smooth and even the MLA sounds.”

New Farm Cinemas Chooses Christie’s Complete Cinema Solutions for Brisbane Cineplex

Christie®, the global leader in visual displays and audio technologies, today announced that its complete cinema solutions comprising the Christie Solaria™ Series projectors and Christie Vive Audio™ cinema systems have been installed in a newly opened cineplex located in New Farm, a trendy inner-city suburb of Brisbane.

Known as New Farm Cinemas, the complex houses six state-of-the-art auditoriums that are color-themed with each theater catered for different purposes and clientele. Meticulously rebuilt over a period of 18 months on the site of a former two-screen cinema known as the Village Twin, the 205-seat Purple Room and the premium Bronze Room with 70 seats are to open to the public on August 1. In particular, the Purple Room is the first theater in Australia to be furnished with Christie Vive Audio solution, which provides an impressive cinematic experience for movie-goers. The installation of this extensive range of cinema solutions was undertaken by Christie and its Australian partner EDGE Digital Technology.

“We applaud New Farm Cinemas for their decision to install Christie’s projection technologies and Christie Vive Audio solution in their refurbished auditoriums situated at this historically and culturally iconic location in Brisbane,” said Lin Yu, vice president, Christie Asia Pacific. “We believe that the performance of our projection and line array speaker technologies provides a great visual and audio experience to every movie-goer and makes New Farm Cinemas one of the hottest destinations in the city.”

The innovative Christie Vive Audio, which offers truly rich, dynamic and detailed sound, unlocks the full potential of the DCI digital cinema audio format and supports leading formats such as Dolby® Atmos™, 7.1 and 5.1 surround sound. Combining the superior audio qualities of ribbon driver technology with the proven high quality performance of a line array speaker design – matched with powerful Class D amplification – Christie Vive Audio is the complete solution that envelopes audiences with dynamic, detailed and captivating sound.

The installation in the Purple Room comprises Christie Vive Audio speakers of varying combinations, including LA1 screen channel speakers, S215 subwoofers (for full range frequency response), S218 for Low Frequency Effects (subwoofers) channels, as well as LA1 and S115 for corner surrounds. Unlike most global Vive Audio installs to date, where surround speakers are mounted on the wall of the auditorium, a corner surround system is specially-designed for the Purple Room as its ceiling has been accorded local and state heritage protection due to its significance as an ongoing cinema since the 1920s.

New Farm Cinemas Chooses Christie’s Complete Cinema Solutions for Brisbane Cineplex

“We are committed in providing our patrons with the best movie-viewing experience by investing in the finest technologies such as Christie’s cinema technologies and equipping our theatres with the most modern facilities at this landmark cinema complex on Brunswick Street,” said Peter Sourris, owner of New Farm Cinemas. “On top of that, we want to extend the experience beyond just watching a film. It’s actually going to be a pretty trendy place to visit, even if you’re not watching a movie. People will come here just for a cocktail. It’ll be like a slice of Hollywood, in Brisbane.”

Besides the immersive aural experience brought about by Christie Vive Audio, audiences can expect nothing but the best visuals from the Christie Solaria CP2215 (equipped with Christie Integrated Media Block solution for seamless conversion and delivery of feature-film and alternative content) and the Christie Solaria One+ installed in the Purple Room and Bronze Room respectively, which utilize the latest generation DLP® Cinema electronics platform. The Solaria Series offers precise vivid color with superior contrast ratios and the light output necessary to light up even the largest auditoriums. The clear choice for any cinema exhibition environment, it is fully capable of providing the world’s most brilliant images, the highest level of content security, the easiest adaptability, operation and maintenance.

Boasting retro carpets, bean bags at the front of each auditorium for couples, arcade games and vintage film memorabilia, New Farm Cinemas is a unique, boutique-style theatre complex that pays homage to the golden age of cinema. Originally constructed in 1921 as the open-air Merthyr Picture Palace, the cinema was remodeled in the 1930s to become the Astor, before transforming into the Village Twin in 1970. The site, bought over by the Sourris brothers in 2013 and rebuilt into a modern 535-seat cineplex, is poised to revitalize this landmark site and turn it into an epicenter of social activity and pop culture. The cinema’s second phase, comprising four extra screens including two Gold Rooms offering top-of-the-range amenities, is currently under construction and is expected to be opened later this year.

Classic Art Deco Theater is Reborn with Renkus-Heinz

Riverhead, NY – August 2014… On December 30, 1933, more than 2000 people attended the Suffolk Theater’s grand opening. Local media declared it “The Radio City Music Hall of Long Island.” The last remaining movie house built by architect R. Thomas Short, and the last remaining large art deco theater on Long Island, the Suffolk Theater entertained generations of moviegoers until closing its doors in 1987.

The building sat empty until 2005, when Dianne and Bob Castaldi purchased it, with a vision of creating a modern performing arts center. Recently reopened after a lengthy renovation project, the venue retains much of its interior décor and charm, while now presenting as a multi-use, state-of-the-art dinner theater with flexible seating, digital projection, and a surround sound system featuring Renkus-Heinz PNX and TRX Series loudspeakers.

The theater’s original raked seating was removed and replaced with a multi-tiered design that allows for varied configurations of tables and chairs, accommodating everything from concerts and performances to dinner theater or movie screenings.

The venue’s audio, video, and lighting systems were designed with that versatility in mind, explains systems designer Stuart J. Allyn of Irvington, NY-based A.D.R. Studios, Inc. “The goal was to provide smooth, even coverage throughout the entire audience area, with proper time domains that would have the sound emanating from the stage, regardless of the seating configuration.”

Allyn chose a pair of PNX121 two-way 12-inch loudspeakers for the main system, with two CFX218 subwoofers for low frequency reinforcement. Ten TRX62 boxes comprise the secondary surround system, as well as providing coverage to the upper and under balcony areas. The boxes were custom painted to blend seamlessly with the venue’s walls. The system was installed by Young Equipment Sales of Hauppauge, under the supervision of Charles Stursberg, Director of Audiovisual Theatrical Lighting and Theatrical Rigging Sales.

Allyn points to pattern control as a major factor in selecting the Renkus-Heinz system. “The TRX62 is my favorite over- and under-balcony system,” he says. “Their dispersion is exceptionally wide, particularly for a box with such a small footprint. The documentation on their coverage patterns is exceptionally true and reliable. Their trapezoidal arrays really do array beautifully.”

Coverage is pointless without great sound, of course. “Renkus-Heinz voices their boxes with a real belief in the human voice,” says Allyn. “When I hear vocals coming out of these boxes, they sound like they should even before I touch an EQ. That’s very important to me. Intelligibility, warmth, depth, character — that’s what the human voice is all about, and it translates to the instruments in the orchestra. If you get human voices to just sound right, you have done your work. And the Renkus-Heinz boxes do that beautifully.“

ASHLY AUDIO PROCESSING AND MULTI-CHANNEL AMPS REVAMP CHICAGO AREA MALL

VERNON HILLS, ILLINOIS: Built in the early 1970s, Westfield Hawthorn Mall is located in the Chicago suburb of Vernon Hills. Its classic mall architecture boasts 4 anchor stores, 180 retail spaces, and 1.3 million square feet of space. However, until recently, its sound system possessed the lifeless quality of 1970s-era contractor-grade components. Music was low-fidelity, speech was of poor intelligibility, and volume throughout was too loud during slow times and too quiet during busy times. Renaissance Communications Systems, located nearby in Franklin Park, Illinois, overhauled Westfield Hawthorn Mall’s sound system. In addition to replacing the ceiling speakers, Renaissance also gave the mall modern auto-leveling control and multi-zone support using two Ashly Audio ne8800M 8-In x 8-Out Protea™ DSP System Processors and two 8-channel Ashly ne8250.70 Network Amplifiers.

“Certainly, one big issue was the sound quality itself,” said Mike Shares, CEO with Renaissance. “The components needed to be modernized. Beyond that, they were having problems with the volume control. First, the system wasn’t zoned properly, so low-ceiling areas had to share the same volume with high-ceiling areas such that neither area could be ideal. Moreover, traffic in the mall varies widely; it’s very slow on a weekday afternoon but very busy on a weekend afternoon or in the rush up to the holidays. The management wanted the sound system to play at appropriate volumes without having to manually track it. They have enough other things to worry about.”

Shares divided the system into thirteen zones based on location, purpose, and ceiling height. Input sources to each zone may be selected independently, and the target volume-over-noise in each zone may also be selected independently. Sensing microphones in several of the zones feed the pair of Ashly ne8800M Protea™ Digital Processors, which analyze the ambient noise and adjust the music or paging output to hit the target sound pressure level. A pair of Ashly ne8250.70 8-Channel Network Power amplifiers deliver 250-Watts per channel to all thirteen zones while taking-up only 4 rack spaces. Nearly 200 full-fidelity Community D6 loudspeakers now deliver the background music with modern impact and convey pages with crystal-clear intelligibility. Of course, paging and alarm overrides provide Westfield Hawthorn Mall patrons with a secure environment.

“I’ve been using Ashly for twelve years now, and I’ve always had excellent results,” said Shares. “The equipment is extremely reliable, and its five-year warranty was a selling point for the client. I have a good relationship with the Ashly support staff, and they helped with the most efficient plan for Westfield Hawthorn Mall. The ambient noise detection and adjustment feature in the Protea software works very well, and the fact that we could fit all of the processing and amplifier channels into just 8 rack spaces was great. That saves space and power consumption.” Based on the success of Westfield Hawthorn Mall, Renaissance has already secured another mall renovation job, where Shares will again use Ashly processing and amplification to deliver excellent performance at a fiercely competitive price.

Power Music of Denmark Takes Newly Purchased HARMAN’s JBL VTX Line Arrays and Crown I-Tech HD Amplifiers to ABC Beach Party

GRENAA STRAND, Denmark — Power Music of Denmark recently added HARMAN’s JBL VTX line arrays and Crown I-Tech HD amplifiers to its inventory. A longtime HARMAN customer, Power Music is a leading regional provider of sound and lighting systems for applications of all sizes. The company recently put its new VTX system to the test at ABC Beach Party, a 12-hour event organized by Danish broadcaster ABC Radio, featuring approximately 25 artists. Held at Grenaa Strand, in Denmark, ABC Beach Party drew an audience of 10,200 people.

“As a JBL VERTEC® user for many years, the time had come for us to take the next step with VTX,” said Rune Hjort, Owner of Power Music. “The launch of the VTX V20 loudspeaker was a perfect solution for our company, providing great flexibility and fast setup with the new ASM suspension system.”

Power Music purchased a total of 16 VTX V20 loudspeakers, along with six S25 subwoofers and six G28 subwoofers. In addition, the company added six Crown I-Tech 12000HD and four I-Tech 4x3500HD amplifiers featuring Crown’s DriveCore™ technology (on top of the four I-Tech 4x3500HD amps the company already owns).

The PA system at ABC Beach Party featured a left-right configuration of eight V20 loudspeakers per side, topped with three S25 subwoofers per side. Six G28 subwoofers were ground-stacked as a center cluster in cardioid mode, while two VTX F12 loudspeakers were used for out fill. All monitors were JBL SRX712 and VRX915M loudspeakers, while side fill monitoring was handled with two JBL SRX725 loudspeakers and two SRX718S subwoofers. A Soundcraft Vi4 digital console was used at the FOH position, while a Vi1 console was deployed for monitors and the entire system was powered with Crown I-Tech HD amplifiers that were controlled, configured and monitored with JBL HiQnet Performance Manager™.

“The last couple of years we have used JBL VERTEC® VT4888 loudspeakers, so we were really excited to see how the VTX system would compare,” said Rune Hjort, Owner of Power Music. “Needless to say it blew everyone away.
Considering the size of the crowd and the fact that the music was very sub-heavy we had some concerns about the amount of headroom. But when you have VTX boxes with I-Tech HD amps in front, you never really run out of power—you can just keep turning up the volume. I also love the fact that we barely had to touch the EQ on the vocals to get it just right.”

DANLEY LOUDSPEAKERS DELIVER AUDIO HORSEPOWER AT CHURCHILL DOWNS

LOUISVILLE, KENTUCKY: Churchill Downs in Louisville, Kentucky held the very first Kentucky Derby and Kentucky Oaks horse races in 1875, the year it opened. The track acquired its now-iconic twin-spires grandstand in 1895 and subsequently added to it on either side in pieces during the last century, bringing the grandstand’s current capacity to 52,000. In anticipation of the 2014 Kentucky Derby, Churchill Downs commenced installation of a 171-ft. by 90-ft. video screen, the largest 4k video board in the world. Because the facility’s low-fi sound reinforcement system had been designed ages ago for only spoken word reproduction, the new screen would require a serious sound system upgrade to realize its full potential and impact. Dallas-based Marsh/PMK International, LLC designed the new sound reinforcement systems for all of the outdoor areas including nearly sixty clusters in the grandstands comprised of Danley Sound Labs SH50, SM96 and SM60F loudspeakers as well as TH212 subwoofers.

Encompass Develop, Design & Construct oversaw the installation of both the new video board and the new sound systems and they hired Marsh/PMK. Dave Stearns and Tim Lindstrom worked with Marsh/PMK to execute the sound system project from conception to completion. “The timeline for such a large-scale project was incredibly short – only six-and-a-half months from start to finish,” said David Marsh, owner of Marsh/PMK. “We were selected as the consultant in early October and delivered the design to Encompass at the end of December with two addenda following in January. Siemens was awarded the installation contract at the beginning of February. They won the bid in part because they have an ongoing contract to operate and maintain the sound systems at Churchill Downs. As such, they were already familiar with the facility and all the relevant operational aspects. Minor installation work and punch list corrections were still going on after the opening of Churchill Downs’ spring meet on April 26. Final testing and adjustments followed to make the system fully ready for the Kentucky Oaks and Kentucky Derby race days on May 2nd and 3rd.”

“I’ve been listening to Danley systems at trade shows for years now,” said Marsh. “I like the company’s philosophy of building large horn systems instead of adding to the already flooded market of line arrays. We see line arrays used in many permanent installations where properly designed horn arrays would work better. People have the idea that line arrays are a panacea, the cure-all for every situation, because they can throw sound long distances and because the main sound lobe can be electronically shaped and steered. True, but there is another side to that story.” Marsh goes on to explain, “Constructive and destructive interference that makes line arrays work also causes noticeable variations in tonal quality. Interference also produces lobes of sound in unintended directions, including behind the array. Lastly, most line arrays have wide horizontal dispersion, the angle of which is usually fixed by the basic building block of the array. In such cases, it is not possible to vary the horizontal dispersion angle along the length of the array to optimally match the intended coverage area.”

Marsh said, “I’ve been looking for the right project for Danley. Churchill Downs became the one. Danley clusters positioned along the front edge of Level 300 serve the largest covered seating tier and all the trackside sections in front of the grandstand building from one end to the other. A tight vertical pattern with sharp cut-offs was critical in our long-throw situation. We had to throw sound all the way down to the edge of the track without ‘sizzling the hair’ of people seated below the clusters where Level 200 protrudes out from the building. The system performs as intended. I was also pleased by the performance of Danley’s TH-212 subwoofers. This is a tapped horn design that delivers an impressive amount of bass in a relatively small package.”

Our original design was based on a different loudspeaker manufacturer, but they couldn’t guarantee that their products would be delivered on time,” said Marsh. “Danley had slightly greater vertical coverage patterns in similar box sizes [to those of the other manufacturer], which allowed us to modify our design to use one less box per cluster. That would ultimately be a cost savings. Danley emphatically stated that the boxes would be delivered on time and that sealed the deal. They made good on their promise.”

Danley Sound Labs, Inc. President and CEO Mike Hedden commented, “One of the things we are very proud of is our U.S.-based manufacturing. From the time we got the order until it was shipped complete was four weeks; 250 fully weatherproofed loudspeakers in four weeks, that’s unheard of in this day of off shore production! During this time the south got hit by two severe snowstorms that wreaked havoc on the region. Even with raw goods being lost in logistics which delayed shipments, we still delivered the products in organized pallets so that each load represented a finished cluster on the job site in four weeks.”

Unlike a typical baseball or football stadium, the grandstand building at Churchill Downs has seating tiers that are stacked vertically, straight up and down. Moreover, various expansions have occurred over the years adding sections on either side of the historic “twin spires.” All of these sections have slightly different profiles. There are varying ceiling heights, seating depths and column spacing. It was a unique situation that required careful planning. Unfortunately, Churchill Downs did not have CAD drawings of the facility. In fact, PDF drawings provided to Marsh/PMK trickled in over a period of weeks and none of them were to scale. “This put the already tight design schedule in serious jeopardy.” Marsh said. “How were we going to get this project into EASE [for coverage modeling] and how were we going to produce usable CAD backgrounds?”

Tim Lindstrom worked with Melvin Saunders, another consultant working on the Marsh/PMK team, to meet the challenge. Tim used dimensions obtained during the initial site survey to create re-scaled PDFs. Melvin used Google Earth to confirm or correct the dimensions and then created a SketchUp model of the complicated grandstands. The SketchUp model was imported into EASE, which finally allowed Dave Stearns to get into the detailed loudspeaker system design. Tim subsequently set about creating the necessary CAD backgrounds. “I was very proud of our team’s resourcefulness.” Marsh declared.

Two basic cluster types alternate along the length of the grandstand, just under the front edge of the Level 300 ceiling. There are nearly sixty clusters in total. The first type of cluster includes a Danley SH50 long-throw box and a companion TH212 subwoofer. The SH50 covers the seating in front of the grandstand building all the way out to the edge of the track. The second type of cluster replaces those boxes with a Danley SM96 to provide near coverage in between the horizontal cut-off angles of the SH50s in the adjacent clusters. Both cluster types include a rear-firing full-range SM60F aimed toward the top of the Level 300 seating tier and a more-or-less down firing SM96 with its woofer removed.

Marsh/PMK expanded existing Q-Sys DSP and QSC amplification to power the system. Existing Renkus-Heinz and QSC loudspeakers were repurposed and added to as necessary to improve coverage on the “porches” in front of upper level suites and on Level 200 of the grandstand building. Renkus boxes were also used on the front edge of Level 200 to cover walkways in front of the building and the rear of Level 100 seating where the Danley coverage is shadowed by overhangs. Existing Community loudspeakers were repurposed and added as necessary on poles to cover seating that extends beyond the building as well as the track infield, the entry plaza and the paddock area. “Re-use of existing equipment where possible was a goal of our design, but Danley now provides the major audio horsepower for the grandstands at Churchill Downs,” said Marsh, claiming no pun intended.
