WORLD TRADE CENTER, CUSTOM BEACON Building one of the brightest beacons in the world— the one that will shine from the top of the new One World Trade Center tower in lower Manhattan—is the kind of challenge that comes around once in a lifetime. J. R. Clancy, Inc. was at the top of the must-hire list when Ballantyne Strong, the entertainment lighting and projection system company, was selected to create the beacon for the World Trade Center. Strong worked closely with lighting designer Claude Engel through the preliminary phases of the project. “Clancy was always our first choice,” said Glen Thor, director of Strong Lighting. Mike Murphy, Clancy’s president, and Strong’s engineering team got together on the project over a 13 month period of engineering work, and were able to get the job to the finish line in less than half that time. The energy-efficient beacon shines at 1,740 feet above the streets of New York, just below the 1,776-foot total height of the new tower. “The antenna structure is approximately 400 feet tall, and consists of 18 separate segments,” explained Tom Trytek, P.E. of TDK Engineering, the firm Clancy chose as its partner in completing the project. “Our component, the beacon, is in the last segment.” The light itself is made up of 16 suitcase-sized petals, each containing 11 modules of LED lights. The bottom 4
petals each contain an array of 22 LED modules. Each module produces 1,200 lumens on its own, for a cumulative total of 316,800 lumens—a light that will be seen easily from Manhattan to New Jersey, even on a foggy night. “The petal array is housed in a stainless steel structure with large mirrors located between the LED modules to maximize and direct the light across the city,” said Bridget Cox, J. R. Clancy director of project management. “The mirrors themselves are not actually glass, but are specialized laminated assemblies of honeycomb board with a custom reflective aluminum surface,” she said. The light sources remain stationary, while the mirror assembly rotates on a small, motorized turntable. A computer supplied by Barbizon Lighting sends a signal to the J. R. Clancy motor control cabinet, turning the beacon turntable on an hour before dusk every day, and shutting it off an hour after sunrise. The motorized turntable, mirror assemblies, and electrical components were built by a manufacturing team led by Clancy, with the assistance of Blair Construction and Fabrication in Auburn, NY. The team paid special
“THE ANTENNA STRUCTURE IS APPROXIMATELY 400 FEET TALL, AND CONSISTS OF 18 SEPARATE SEGMENTS,” attention to reducing the potential for maintenance and repair issues. “The entire beacon is exposed to the elements, so it had to be designed to withstand New York City heat in the summer, cold in the winter, and precipitation,” said Cox. “There’s a special enamel paint treatment used for all of the parts that could not be made out of stainless steel. The stainless steel motor control cabinet can withstand the summer heat intrinsically, but if the temperature drops below 40 degrees, internal heaters kick on to keep the control components at a relatively constant temperature. The turntable motors are also equipped with heaters to help avoid condensation.”
Maintenance at 1,700 feet
Designing a super-bright lighting fixture is challenging enough, but the fact that this beacon lives above 1,700 feet required the design team to think through every aspect of maintenance and repair. “The specifications from the architect were that the beacon was to be fully capable of being dismantled and replaced in place,” said Trytek. “The beacon is segmented, so every component can be removed individually and replaced.” Clancy and TDK examined every aspect of the original design to determine the best ways to simplify and ruggedize the structure, reducing the likelihood of a mechanical breakdown. They took a 180-degree approach to the methodology of turning the system. The turntable structure involves a slew ring bearing—a single large, circular bearing with a projected life of one billion revolutions. “It turns as fast as a second hand, and it operates roughly twelve hours a day,” said Trytek. “With proper maintenance, it could last almost forever.” Just to be safe, though, Clancy built a second gear motor into the turntable to provide a redundant motor drive system, so the beacon would still operate in the event that one of the motors malfunctioned. “The slew ring is so much simpler, with an infinite lifespan, and it’s very easily serviceable,” said Thor.
Even with all of these precautions, the team knew that service personnel would need to access every part of the beacon for routine maintenance and repairs—both for the beacon itself, and for the components above it. “Through the center of the mirror system is an access ladder,” said Trytek. “Just above the beacon on the tower are four FAA lights, as well as a light at the very top of the antenna. So we had to be sure that a maintenance person could pass through without interfering with the mirror, to reach the lights at the top of the tower.” While some of the mirror panels are fixed to the frame of the beacon housing, the center panels can be removed, “sort of like a leaf in a table,” Trytek explained. “Each of the leaves of the mirror system can be stored to the left and right sides of the mirror frame. So you have an unobstructed way to get to the upper and lower petals of the LED system.” With the beacon soon to cast its light across Manhattan, Thor is quick to praise the expertise the Clancy team brought to the project. “Clancy’s role has been instrumental; we couldn’t have done it without them,” he said.

STUDIO SOUND ENGINEERING Alchemea College installs a Duality SE system to aid in creative media training. “DUALITY HAS ALL THE SONIC BASES COVERED, SO IF YOU WANT TO HAVE A CLEAN AND OPEN SOUND YOU CAN, BUT THE VHD MIC PRES ALLOW STUDENTS TO FATTEN UP THE SOUND AS WELL.”
Alchemea College is a creative media training college that specializes in full-time and short audio engineering, music production, live sound, and video courses. The college recently installed a Solid State Logic Duality SE studio sound engineering program to offer students a wide variety of skills to take into the real world for the different needs and challenges they will face. “When the time came to get a new console, we wanted a desk that was analogue, had full 5.1 mixing capabilities, and offered in-depth DAW control,” says Neil Pickles, director of short courses for Alchemea. “Looking at the current available analogue consoles, Duality appeared to have an advanced implementation of DAW control over other consoles we considered. Duality offers an industry-standard channel configuration with mic pre, EQ and dynamics, along with flexible routing and real 5.1 mixing. The brilliant A-FADA (Analogue Fader Accesses DAW Automation) system, which allows the DAW automation to drive the faders on the console, makes Duality the perfect teaching tool for advanced students.” The console lives in the Solid State Logic Duality
Control Room, Alchemea’s flagship studio, and is used for mixing and tracking. Capture is through a Pro ToolsTM HD system and a two-inch 24-track analogue tape recorder. The control room enjoys natural light during the day with complete climate control to promote a relaxed creative environment for working on Duality. Students also have access to a plethora of high-quality plug-ins and racks of outboard dynamics and effects units that are brought together through Duality. According to Pickles, “Duality has all the sonic bases covered, so if you want to have a clean and open sound you can, but the VHD mic pres allow students to fatten up the sound as well. The console also offers the classic RMS-style E/G compression and peak mode compression. Duality provides students with the feature benefits to help them understand the creative nuances of sound production.”

HYBRID SPORT TRACK TECHNOLOGY The Sport Track technology enables robotic cameras to automatically follow live sports action, which cuts live sports production costs. As a leading provider of real-time graphics and robotic camera systems, Hybrid has developed Sport Track, an exclusive technology that enables robotic cameras to automatically follow live game action. The technology sends positional tracking data from the manned master camera to an unmanned slave camera so that it can follow the game’s movement. Sport Track enables sports broadcasters to reduce the number of manned cameras required to cover a live game, which not only reduces operating costs, but enriches the quality of the program because broadcasters and production companies can employ more cameras to cover the game while staying within increasingly tight, competitive budgets. Hybrid’s greatest challenge in producing the Sport Track was to create a robotic camera that could see and follow fast moving live game action like soccer or football in real-time. Hybrid discovered that a manned Cartoni motion tracking pan/tilt/zoom/focus (PTZF) camera could serve as the master camera, which is then networked to a Hybrid Titanium robot camera head. Using newly developed software and drivers from Hybrid, all of the camera data—including position, angle, distance, and speed—could be optically tracked, encoded, and transmitted by the Cartoni camera over to the Titanium robotic camera head. The corresponding coordinates tell
the Titanium (robotic slave) camera head how and where to move to follow the game action precisely. The idea for Sport Track was originally inspired by Host Broadcast Systems (HBS), who approached Hybrid with a need for the technology in the coverage of their live soccer championships. The company also found interest in their automatic camera system when talking with sports broadcasters and producers who wanted to increase the number of cameras for a more visually interesting live game without increasing operating costs.
