A renovation of Kyle Field in College Station, TX, home of college football’s Texas A&M Aggies, has seen the athletic department’s 12th Man Productions implement an IP infrastructure for its audio network utilizing Audinate Dante. In total, the new infrastructure implemented over the past few years has 48 fiber optic runs that tie 12th Man’s Kyle Field-located control center to the school’s seven main sports venues, controlling all venues from the centralized area.
In the project, the 12th Man team, which includes 18 full-time staff members and up to 90 Texas A&M undergraduate students, moved into a new facility in the stadium, created with a nearly $12 million investment in the electronics infrastructure to serve the athletic department. The facility hosts four HD control rooms, an ESPN bureau cam studio, a main studio set area, a radio broadcast room, and six post-production edit rooms, with 12th Man producing 110 events a year.
“When we started the renovation, we had to choose our audio network platform, and it was obvious that Dante fit our immediate needs and was also supported by the industry enough to cover our future plans,” says Zack Bacon, chief broadcast engineer for Texas A&M who oversees all technical support for the 12th Man Productions facility. “We definitely have an extensive Dante deployment, and we’re trying to grow it as much as possible. It’s a great technology, and we can vouch for its flexibility and how using the IP infrastructure allows us to do a lot of things we wouldn’t otherwise be able to do.”
Bacon explains that as a centralized facility, audio from all facilities is transported to the production control rooms via Dante, and nearly all audio for broadcast is on a Dante network as well. The team produces everything essentially through Dante with Yamaha consoles. The audio signals are mixed, married to the video, and then either used within the venue or broadcast out. The team also has a direct fiber connection to ESPN, allowing them to share audio and video content directly.
“We have four control rooms, so we’re able to do two sports at a time,” he says. “That means two big-screen shows and two ESPN broadcasts simultaneously, so things can get pretty hectic — and we’re relying on Dante more and more so we can be as efficient and responsive as possible.”
Recently, the team upgraded its Studio Tech 214 announcer consoles to be Dante native, helping to improve audio quality and signal flexibility. The team has also integrated this type of Dante connectivity into its intercom system and are able to directly patch the announcer consoles into the intercom system as well as the audio mixer. Now, when they need to feed audio in and out of the intercom, they can do it straight through the Dante network and into whatever source or destination desired.
The networking also has been implemented with venue PA system.”There are multiple ways we could get it into Dante and to the PA mixer, but we run it through our console and do direct out, then we set up the shared audio group within Domain Manager,” said Bacon. “Then we just do the patching in the Dante Controller, and as long as we have the network infrastructure set up, everything just works.”
The PA systems are distributed audio DSP networks that are all interconnected by Dante because of the large distances covered. The Dante network delivers the signal to a network of Harman London BLU DSPs, and from there to the individual amplifiers.
“With Dante Domain Manager in the football stadium, we’ve already seen the benefits integrating the PA and being able to send multiple sources to the PA mixing console, as opposed to previously, we would only be able to send two,” said Bacon. “We’re currently working with and sending about six audio signals, but we can obviously send a lot more. This has been a very convenient and efficient way for us to improve our workflow to make sure we’re getting audio to the PA and the football stadium so that the show can go smoothly, and everybody can hear it cleanly.”
Domain Manager is network management software that enables user authentication, role-based security, and audit capabilities for Dante networks while allowing expansion of Dante systems over any network infrastructure.Domain Manager organizes a network into zones called “domains” that each have individual access requirements, making it clearer and easier to know who can access any area of the system. All activity is logged, tagged, and date-stamped so problems can be identified and solved.
With Domain Manager, Bacon and the 12th Man Productions team are able to route their audio signals across subnets to cover the multiple venues and the production areas. It enables them to create management groups and to segment areas, venues, subnets, and production rooms as needed. The team is now able to create some very granular control and security parameters across the network.
“Our student workers do many functions for us, everything from operating cameras to post-production, and we have about 20 student engineers as well who are out in the field making sure everything is working and are actually connecting everything and mixing the shows,” says Bacon. “Our student engineers are trained on Dante Domain Manager, and they now do the routing and patching for the various productions, and we don’t want operators mistakenly going into Dante Controller and re-routing anything that might impact other simultaneous events.”
Domain Manager coordinates multiple subnets, allowing Dante audio to be used across networks of nearly any complexity or size, and it also enables audio to be plugged into any Ethernet jack, anywhere on campus, and route the audio data to where it needs to go. Users of Dante-enabled devices do not have to perform any special configuration; Domain Manager automates this task.
Texas A&M Athletics’ award-winning 12th Man Productions handles the television production needs for Aggies sports – including content for 12thMan.com, TV shows, videoboard presentations and ESPN’s SEC Network productions. Along with producing live broadcasts and video features for all teams, 12th Man Productions also entertains A&M fans with television shows such as The Pulse, which gives fans an up-close look at Texas A&M Football in the fall.
