BYU-Idaho Brings On DiGiCo

The 15,000-seat auditorium inside Brigham Young University-Idaho’s new BYU-Idaho Center recently installed DiGiCo SD7 consoles at its FOH and monitor positions.

Rexburg, ID (February 6, 2012)—The 15,000-seat auditorium inside Brigham Young University-Idaho’s new BYU-Idaho Center recently installed DiGiCo SD7 consoles at its FOH and monitor positions.

The 435,000-square-foot building contains a 15,000-seat auditorium and a multi-purpose area large enough for 10 full basketball courts. In addition to recreational activities, the gym will serve as a place for large social gatherings. The auditorium will be used for large-scale performing arts productions, a weekly Tuesday devotional meeting, as well as other academic and entertainment endeavors for students, faculty and the community.

The process to outfit the venue with a complete audio/visual system took roughly three years from conception to completion, spearheaded by senior project engineer Andrew Prager of New Jersey’s Diversified Systems with the aid of BYU-Idaho’s audio engineer David Mann. Mann’s number one design criterion for the system was overall speech intelligibility. “As this is primarily a worship facility,” he explained, “the spoken word is the reason the facility exists and was of utmost importance to everyone involved.”

Armed with that missive, Prager identified the scope of the system and its components, which included a front end and monitor mixer, digital signal processing, amps, and speakers. As for the mixer specifically, it needed enough inputs/outputs to be shared between both the FOH and monitor mix consoles. Additionally, it needed to be digital and fiber-optic based. The sale comprised the two SD7s and six DiGiRacks—one dedicated to each console at FOH and monitor world, with four shared between the two.

Having a fiber optic-based system was also top priority. “It’s very cost effective to run fiber,” stated Mann. “Obviously, the cost benefit of fiber is much more budget-friendly, but also the amount of information you can send via fiber optics is incredible.”

“The things that come to my mind when we’re talking about digital audio traveling as light instead of through copper is that it’s faster in terms of latency,” Prager added. “It gives us a smaller cable pathway rather than big fat copper hoses running around the place, and there is a built-in immunity to grounding problems, which can be caused from different power ground and sources. We have a third party digital audio transport system running MADI over Opticore—a dual ring of fiber that goes between the mixer and the DiGiCo stage racks. It’s a very robust, very redundant system and because it’s a ring there’s a connection of fiber and the signal can just come from one way or go the other. “

The consoles areused for events ranging from BYU-Idaho’s on-going weekly Tuesday devotional service to a small number of musical and theatrical productions. “Both the events and the Tuesday services range in size and scope. The Tuesday service, with its single talking-head presenter, also showcases a special musical number, which ranges from a soloist with piano accompaniment to a 350-voice choir with orchestra. Depending on the week, it can be very simple or very demanding. On our typical devotional, we’re running approximately 6-8 inputs; on an elaborate one, it’s more like 80.”

Coming from a live sound background, Mann said the challenges of the worship environment are very much different. “When you’re working with a band and vocalists, you generally get a good strong sound coming into your console so you have something solid to work with. In a worship environment, dealing with a single speaker on stage, especially in a podium-type situation, you don’t always get a great level and so it’s a challenge to get enough signal before it starts to feedback. That’s my main challenge in this environment. I think I would rather mix a 300-voice choir and 80-piece orchestra any day over a single voice speaker!”
