Formative AES Technical Committee on Sound for Digital Cinema & TV AESTC-SDCTV

New Initiative To Review Audio Reproduction For Digital Cinema

NEW YORK: The Audio Engineering Society has formed a provisional committee to review audio reproduction for Digital Cinema and Television . Spearheaded by Brian McCarty, Managing Director, Coral Sea Studios (Australia), the new AES Technical Committee on Sound for Digital Cinema & Television, AESTC-SDCTV is planning a meeting in Los Angeles in early 2012. To participate in this event or to join the AESTC-SDCTV Committee contact: Brian McCarty (http://www.aes.org/technical/aft/).

“Our mission is to identify a consistent approach to controlling perceived loudness and frequency response from installation to installation, and from position to position within Digital Cinema installations worldwide,” McCarty said. “And, for this to be adopted as the formal reference for all contemporary dubbing stage recording and mixing activities, and ultimately as the unified method for film reproduction at home.”

Originally addressed at AES Technical Committee meetings in London in 2010, the initiative was inspired by the AES historical involvement in film sound. The lack of electroacoustical response reference data for Digital Cinema systems was underscored by Dr. Floyd Toole’s statement, “It seems that no real science has been done in terms of Digital Cinema Sound.” Dr. Toole, Vice Chair of the committee, is developing a 1/2 day seminar on these issues to be held in L.A. in March that will serve as the first meeting of the committee.

McCarty underscores the point that global acousticians, engineers and systems installers have expressed the need for a working standard. “In simple terms, what is recorded digitally in the studio does NOT sound the same at the theatrical end,” McCarty says. “As an art form our goal should be consistency of sound quality. Acoustical design of theaters is typically incorrect for sound reproduction in large rooms. Current soundtrack EQ reproduction curves are inconsistent with large-room audio practice and, with the rest of the audio industry. And, loudspeaker technology typically used in theaters has yet to be optimized for proper playback of wide bandwidth soundtracks. Basically,” McCarty concludes, “the current Digital Cinema Audio System is simply not the best we can do. The AES is committed to improving this situation.”

Professional Wireless Systems Pioneer Domed Helical Antenna

Innovative Design, Rugged, Road Friendly, Cost-Effective Wireless Performance

ORLANDO, FLA: This summer, as he began sorting out the RF co-ordination for the Lollapalooza Festival, Ohio-based Eighth Day Sound director of touring services Owen Orzack reached out to Professional Wireless Systems’ GM, Jim Van Winkle, for recommendations on multi-channel wireless distribution. Coincidentally, PWS was putting the finishing touches on their innovative new Domed Helical Antenna.

“We’d worked with Owen on previous tours for various major acts, and Eighth Day already owned a number of our proprietary Helical Antennas,” Van Winkle reports. “While Owen already planned to use our Helicals for Lollapalooza at Chicago’s Grant Park, I said we would be happy to supply our new Domes for him to try out at the event.

Shipping immediately, the new PWS Domed Helical Antenna incorporates the highly successful circular polarization configuration pioneered by their original Helical, but seals the unit within a unique new compact ‘Domed’ design. Constructed from rugged Polycarbonate, PWS Domed Helicals are designed to hold up to considerable road-related abuse. Developed to provide robust, uncompromised multi-channel wireless microphone, in-ear and intercom wireless connectivity, PWS Domed Helical introduce a new standard in wireless antenna performance and physical presence.

“The Dome offers the same solid benefits of the original Helical with its circular polarization and applies it to a wider coverage pattern,” Van Winkle says. “In addition to Lollapalooza, we also provided Domed Helicals for the Austin City Limits Festival in September. And, Owen just let us know the Domes were very well received on tour with The Fray. Now that we’ve confirmed their quality and dependability we are rolling the Domes out across the industry,” Van Winkle concludes.

SYMETRIX SYMNET WITH SYMVUE CONTROL TECHNOLOGY HELPS HYATT REGENCY CALGARY KEEP IT SIMPLE

CALGARY, ALBERTA, CANADA – NOVEMBER 2011: The Hyatt Regency Calgary is one of the finest hotels in the Canadian city for which it is named and, as such, hosts a tremendous volume of extravagant and top-drawer affairs. The hotel’s nine combinable ballrooms and six combinable meeting rooms are constantly in use for business meetings, weddings, and other events. However, until recently, the Hyatt’s management and staff struggled to control the audio system that delivered sound reinforcement to those spaces. It had been a challenge from day one and only became more frustrating as time passed. While in the process of undergoing a seven million dollar renovation to the ballrooms and meeting rooms, hotel management made the decision that it was also time for a major change in regards to the sound and video systems. Hyatt management asked Calgary’s DBI Systems Integration to design and install the new systems. Using Symetrix SymNet DSP technology, Symetrix SymVue user interface technology, and Symetrix ARC-SWK wall panel remotes, DBI Systems Integration provided an audio system that was simultaneously comprehensive enough to allow infinitely flexible use of the event spaces but simple enough to be controlled even by non-technical staff.

“The old system was first-generation digital technology, with one manufacturer for the DSP and one manufacturer for the user control,” said Jerry Van Dyke, owner of DBI Systems Integration. “The interfacing between the sets of technology was very cumbersome and unreliable at best and the hotel had spent a small fortune just keeping it limping along since its original installation by another company.” Our goal was to give them everything that was so obviously lacking in the old system. The systems would have to be simple to operate, flexible, and reliable while still being powerful enough to handle the complex tasks required.”

A significant component of the design solution was to avoid involving two manufacturers, as had been done previously. “Even today, equipment from different manufacturers doesn’t always integrate as seamlessly as it should,” he said. “Often when a problem does arise, each manufacturer will claim that it is the other company’s fault. There have been instances where each company washes its hands of the problem, and you’re left in the middle with an unhappy client. I was impressed with Symetrix’ significant strengths in both the processing and the interface sides. Based on past experience I knew that if I ran into any trouble, Symetrix would be there to help us solve any issues!”

Van Dyke called on three Symetrix SymNet Express 8×8 CobraNet devices to provide the appropriate input/output count with powerful open-architecture processing to customize the routing logic for the Hyatt Regency Calgary. The three units gather inputs from the nine ballroom sections, the six meeting rooms, and four divisible sections of a grand foyer and allow them to be routed anywhere. On average there is one to two inputs in each zone with some zones having up to three inputs with some inputs being summed. To keep it simple, a 15-inch touch screen computer was employed and they overlaid a schematic of the rooms with buttons that allow them to be easily combined or decoupled via the Symetrix SymVue interface technology. “Via the touch panel they just press the rooms they want to combine and those rooms change to a common color to indicate that they are combined,” he said. “They can un-combine them in the same way, or press a reset button to start fresh.” There’s one page for the ballrooms and foyer and another page for the meeting rooms.

In addition, Symetrix ARC-SWK remote wall panels provide each room with local control of input sources and master volume. When rooms are combined, their ARC-SWKs become redundant. A combination CD-player/iPod-player back at the control room provides common background music that each room can tap if needed. “The routing logic and processing at the Hyatt Regency Calgary is actually tremendously complex,” said Van Dyke. “But with Symetrix’ well thought-out interface technologies, we were able to keep all of that under the hood and hidden from view. The controls that we have designated as presets are so intuitive that truly, anyone can figure them out with an absolute minimum of training.”

Two-hundred-watt AMK twelve-inch coaxial ceiling speakers went in with the old sound system, and Van Dyke was happy to tell the hotel that they could be utilized in the new sound system. “Those speakers are very good quality, but the previous installer had tapped them at 30-watts and then used 100-watt amps to power groups of three,” he said. “It was like running a race car on a 40-mph governor when you consider the problem of getting high SPL to the floor cleanly when the Hyatt’s ballroom ceilings are twenty-two feet high.” “The Hyatt often has events where a significant level of SPL is required and we wanted to be sure that this would no longer be a problem for them to achieve.” To give the Hyatt the performance of “new” loudspeakers for a song, he added five 4-channel QSC CX204V and six 2-channel QSC CX302V amplifiers. He added 200-watt transformers to each loudspeaker and then tapped them at a much more generous 100-watts with there being an option to tap them higher if it was required “Even if I ignore the contribution of the new processing, it’s an obvious and drastic improvement to the overall system sound,” said Van Dyke. “Whereas before the Hyatt would suggest that clients bring in their own rented sound system for music-heavy events, the newly-adjusted ceiling speakers sound so good that they often don’t need to.”

“It’s easy to focus on Symetrix’ sophisticated user control, but the sound quality is top-notch as well. Symetrix started in the broadcast and recording markets, where sound quality is a really big component of what matters. That legacy helps to make Symetrix processors sound fantastic,” Van Dyke concluded.

Edge ShowTek Makes Use of AuviTran EtherSound Unit for Red Bull Fuel & Fury

BUENA PARK, Calif.—More than 5,000 attendees flocked to the site of this year’s Red Bull Fuel & Fury snowmobile jumping event. Held in early November in Chicago, they witnessed seven of the world’s best freestyle snowmobilers at the largest single event of the year.

Edge ShowTek (Northbrook, IL) was tasked with the audio production for the event, making good use of the new AuviTran AVM-500ES unit to maintain an EtherSound network within the entire digital system. The system consisted of a Yamaha PM5D-RH digital console, two Yamaha SB-168ES Stage Boxes, 36 NEXO GEO S8 speakers, 12 CD12 subs split between four towers, six NEXO PS15s, and five NEXO NXAMP 4x4s amplifiers.

The AVM-500ES unit is an EtherSound Network Matrix housed in a 19” 1U rack box for linking and routing up to five EtherSound networks together, Integrating a full matrix router of 320 x 320 audio channels. “The unit worked very well, states Pete Hansen, Operations Manager, Edge ShowTek. The reason we decided to use the AVM-500 was to maintain an EtherSound network throughout the whole system, which would not have been possible without the unit, or at least very undesirable from a cabling standpoint.”

Hansen said the setup for this system was quite unique in that speaker positions were both in front of and behind the Yamaha front of house position. The Edge ShowTek crew used a combination of Cat5 and Fiber Optic cable runs that were fairly long and non-linear with about 200-300 feet between each speaker tower. They were able to save about 1,000 feet of cable run by splitting the ES network in front of, and behind, the front of house position by using the AVM-500.

“We have been using EtherSound as a method of running multi-channel digital audio for years, says Hansen. It’s amazing to hear how well the audio fidelity is maintained when you never leave the digital domain, says Hansen. If you are going to use a digital console, you might as well run in a digital format like EtherSound as much as possible. The AVM-500ES allowed us to do just that over the whole system, and it sounded phenomenal.”

“An event like Fuel & Fury was an ideal use of EtherSound networking given the large distances between microphone sources, speaker towers and the Yamaha front of house, notes Trevor Waller, of Edge ShowTek and A1 for the event. With announcer microphones over 600 feet away from the mix position, the ability to send those sources to the Yamaha PM5D-RH console digitally with virtually no line losses was a great advantage in making sure the event could be heard by everyone even over the roar of snowmobiles in the air. The unit was virtually plug and play and allowed us to save valuable setup time, both in its ease of patching and integration into our system.”

Electro Acoustics Installs HARMAN’s JBL VLA Line Arrays At University Of North Texas’ Newly Constructed APOGEE Stadium

APOGEE Stadium at the University of North Texas features an audio system comprised of JBL VLA line arrays.

NORTHRIDGE, California – At the epicenter of the University of North Texas’ “Mean Green Village” outside of campus, Fort Worth, Texas-based Electro Acoustics has outfitted the newly constructed APOGEE Stadium with HARMAN’s JBL VLA line arrays. Designed by Gary White of Wrightson, Johnson, Haddon & Williams, Inc., it was important for the PA system to provide high output, high clarity and immense power.

The 30,850-person capacity APOGEE Stadium features a main scoreboard system comprising eight JBL VLA901 line array loudspeakers, combined with eight VLA601 loudspeakers, each split four to each side. Three additional VLA901H and four VLA601H loudspeakers round out the scoreboard sound system. Installed throughout the stadium for additional PA support are 74 Control® 26CT ceiling speakers and 18 Control 30 outdoor monitor speakers.

“JBL’s VLA line arrays provide the power and reliability the client required in such a demanding venue,” stated Chris Jordan, president of Electro-Acoustics. “The speakers are perfect for an outdoor environment. We focused on providing a loud system that could withstand any inconvenient weather. The VLA loudspeakers are performing exactly as they were designed.”

Crown amplifiers power APOGEE Stadium’s sound system, which also features BSS processing. The entire system is controlled through HARMAN’s HiQnet System Architect™.

To help make certain construction of the stadium was completed on time, Electro Acoustics designed, built, tested and tweaked the entire system in its studio–an important strategy to ensure the safety and structural integrity of the construction site.

“The speakers were easily rigged and time was the only challenge when dealing with the new construction of APOGEE,” Jordan continued. “UNT was our first major install of VLA line arrays and we are very proud of the outcome. The stadium sounds amazing. The clients received exactly what they expected, on time and on budget.”
