By PSW Staff • September 10, 2018 According to U.S. News & World Report, you can find the 2018 top-ranked regional university in the South in the Piedmont area of Central North Carolina, between Greensboro and the Raleigh-Durham-Chapel Hill triangle. There, Elon University sits on 636 acres that Best College Review ranks as one of the most beautiful college campuses in the country. Clearly not an institution that rests on its laurels, Elon University has just opened the all-new Schar Center, a 160,000 square-foot, 5,100-seat arena which serves as the new home for Elon Phoenix basketball and volleyball and a center for major campus events. In addition to the main arena, the Schar Center boasts a spacious entry atrium, a large practice gymnasium, locker room and team facilities, and a hospitality room for social events and gatherings. Audio & Light designed and installed the AV systems for this beautiful and extensive new facility, including a sound system that relies on Linea Research power amplifiers. “This is the first time we have spec’d or used Linea Research amplifiers, and so far, they have been very impressive,” reports Audio & Light Installation Division Vice President Brian Cox, who designed the Schar Center AV systems. “We’ve been impressed with Linea Research amps’ DSP capability and ability to do all of our speaker processing in the amplifier per channel—and the power output is incredible.” The arena has no acoustic treatment, relying on the design and quality of the sound system. To ensure that quality, Cox designed a Dante system featuring Fulcrum Acoustic loudspeakers driven by Linea Research 88C10 and 44C20 power amplifiers and networked with Symetrix Edge DSPs. “The main sound system over the court, covering the seating area, consists of 24 Fulcrum Acoustic AH96-FP ‘full passive’ loudspeakers, configured as 8 arrays of 3 loudspeakers each,” describes Cox. “Each of those arrays also includes a Fulcrum Acoustic CS121 subwoofer, for a total of eight CS121s. On the north side, the seats go up much higher so we installed five Fulcrum DX1295-FP fill speakers. On the east and west ends of the arena, on the concourse, are seating that’s shaded from the main system, so each end is filled with six Fulcrum Acoustic GX1295s. That requires a total of 40 amplifier channels for the mains and fills and 8 channels for the subwoofers.” Five 8-channel Linea Research 88C10 power amplifiers drive the 40 channels of mains and fills, while a pair of 4-channel Linea Research 44C20 amps drive the 8 subwoofers. A sixth Linea Research 88C10 is kept in the rack, unpowered, as an emergency spare. “Using the full passive loudspeakers was made possible by the Linea Research amplifiers,” Cox explains. “Fulcrum Acoustic speakers work extremely well with Linea amplifiers. The Linea Research amps’ built-in DSP gave us the ability to process the limiting by frequency, rather than just limiting by level. They can close down on high-frequency damage before it happens, without having to worry about the low frequencies.” Linea Research 88C10 and 44C20 power amps fully integrate 96 kHz DSP with algorithms designed in-house at Linea. Users can create custom FIR filter sets on each channel with up to 384 taps at 48kHz resolution, or 768 taps at 96kHz. Linea Research amps boast Level 1 compatibility when used with Fulcrum Acoustic loudspeakers. “This was one of our first projects using Fulcrum Acoustic Level 1 presets,” offers Rik Kirby, president of Allied Professional Technologies, Linea Research’s US distributor. “This compatibility has been proving very popular, and the end result sounds great. And Fulcrum Acoustic have been able to implement Linea’s Virtual Crossover (VX) Limiter, allowing them to limit LF and HF separately despite using a passive crossover in a mid-high device.” “We wanted this to be a Dante digital system so we could make it as flexible as possible,” offers Cox. “The Linea amplifiers come with an option for Dante I/O, and they work very well with the Symetrix Edge DSPs. We have one Edge for arena processing, one for auxiliary area processing in other parts of the Schar Center, and a third Edge for routing and switching. The Linea amplifiers have three network ports: one for control and the primary and secondary Dante ports. The Symetrix DSPs, Linea Research amplifiers, and Fulcrum Acoustic speakers have so far worked together flawlessly.” When deciding on Linea Research amplifiers, Cox considered multiple factors. “It seemed like the Linea Research amplifier was designed for the Fulcrum Acoustic speakers we wanted to use,” he details. “In fact, the Fulcrum Acoustic rep first brought Linea Research amplifiers to our attention. We looked at other brands but anything else that had Dante didn’t have enough DSP horsepower, and the Linea Research amplifiers’ power-to-size ratio and output capabilities are among the best on the market. To go with another brand, we probably would have ended up with more external DSP power and larger amplifiers with more heat load. And programming the Linea Research DSP was easy; we had the amplifiers updated, loaded, and ready to go and passing audio in one morning.” Audio input for the arena system is through a Yamaha TF1 16-channel mixer with a NY64-D Dante I/O card. The mixer rolls out in a mobile cart, which includes a headset and computer inputs, providing a complete solution that can be located at the scorer’s table for sporting events. Floor pockets enable the mixer to send Dante audio to the network. “The Schar Center is great; it’s a beautiful building,” proclaims Cox. “The athletic departments are now using their new offices, and the basketball and volleyball teams have moved in. The arena opened with a women’s volleyball game on August 28, and the sound system did a really good job. The Linea Research amplifiers’ sonic performance so far seems to be above everything else. Everybody here is very happy.” Linea Research Tagged with: 44C20 88C10 DSP Elon University Fulcrum Acoustic Linea Research Loudspeakers Schar Center · all topics Subscribe to Live Sound International Subscribe to Live Sound International magazine.
