As the largest Christian university in the world, Liberty University enrolls more than 110,000 students across 550 unique programs of study on its 7,000-acre Lynchburg, Virginia campus. For its state-of-the-art School of Music facility, Liberty University has deployed a Dante audio-over-IP network from Audinate to transport audio throughout the building.

“I’d estimate that we’ve saved about $40,000 to $50,000 on capital and operating expenses since shifting from our legacy networking system to Dante,” said Michael Gerringer, AV Architect/Manager for Liberty University. “We’ve saved hours and hours of work because there’s no need for cumbersome cable runs, hard wiring and patching devices to put them onto the network.”

Gerringer is part of Liberty University’s Infrastructure Media Operations team responsible for designing, deploying and managing the IT technology that is used throughout this large, high-profile institution. Dante was a big attraction for Gerringer due to its seamless operation over existing IT infrastructure. A virtual private local area network (VLAN) has been established for Dante audio networking throughout the School of Music, keeping it logically separate from the main enterprise LAN.

“Dante gives us enormous flexibility and latitude in how and where we route digital audio throughout our facility, including five classroom/ recital spaces and our Performing Arts Center auditorium,” Gerringer says. “Since the Dante network is virtual, each audio network configuration can be configured or modified quickly in software. Having this advanced audio networking capability has elevated our ability to teach music students how to mix and produce live sound effectively for any application or event.”

Approximately 15 Dante-enabled products currently reside on the 1Gb network, including a DiGiCo SD5 mixing desk in the auditorium, Yamaha CL1 mixers in classrooms, an Aviom D800-Dante A-Net distributor in each classroom and the concert hall. DiGiCo Orange Box I/O interface units convert MADI signals to Dante, and an RTS ADAM modular matrix intercom, equipped with OMNEO interface cards, supports intercom communications between different areas of the facility.

“Configuration and management is simplified as systems like the Yamaha CL1, and their companion RIO I/O stagebox systems, appear instantly when they’re plugged into the local area network,” said Gerringer. “We are also very picky about low latency and high sound quality, and Dante is exceeding everyone’s expectations.”

One application of educational value that especially excites Gerringer is the ability to use virtual soundchecks as a teaching tool. With virtual soundchecks, School of Music students can access isolated digital recordings of every aspect of a live musical or theatrical performance that took place in the auditorium. They can then practice mixing and finessing these audio inputs into a finished mix using the Dante-enabled Yamaha CL1 mixer in their classrooms.

“Routing throughout the School of Music enables students in the classrooms to practice mixing live sound streaming from the concert hall, or to virtual soundcheck audio sources, such as the vocals or drums, that were ISO-recorded during live performances,” said Gerringer. “With this networking flexibility, we’re hoping to empower people here by making it super easy to set-up, control and route audio, when and how they see fit, without help from the IT team.”

Moving forward, the IT team plans to use Audinate’s new Dante Domain Manager to establish different network domains. This will allow different facility groups to discretely use Dante for their own operations, including the institutional, production, broadcast and academic departments.
