Dante enables at-home broadcasts for university


The University of Miami’s pre-2020 decision to redesign its live sports production workflows to incorporate Audinate’s Dante has enabled it to respond flexibly in light of COVID-19.

The university choose to ensure all audio feeds were on the network with Dante, from field mics to mixers.

“We don’t have a single XLR patch anywhere in our workflow,” said Anthony Lestochi, director of production services at the university. “Moving to Dante was clearly the better way to operate. It made building out our production really easy and effective. And, when COVID happened, Dante made it easy to quickly adapt.”

Audinate designed Dante to distribute hundreds of uncompressed, multi-channel digital audio channels via standard Ethernet networks, with near-zero latency and perfect synchronisation. Dante allows audio, control and all other data to coexist effectively on the same network.

Over the course of 2020, as productions needed to drastically alter their approach to adhere to COVID-19 safety guidelines, the ability to use Dante audio-over-IP as a connective fabric was an enabler.

Social distancing

“When we looked to bring production back, the first thing we did was knock walls down in our control room,” said Lestochi. “We totally rearranged the space and put up new physical barriers to allow for effective social distancing in the new control room. Because it was a Dante-backed system, we could run all of our new positions for equipment onto the network and know it would work quickly. It was a very easy change, and one that wouldn’t have been so quick if we were using traditional cabling.”

The control room continues to make use of the same broadcast technology in place prior to the change in physical layout. Two Yamaha CL5 mixing consoles and a Behringer X32 mixing console provide all mix capabilities for the many Dante signals on the network.

Field and announcer microphones located on site are made Dante-native using Shure ANI4IN audio network interfaces. Multiple Studio Technologies 45DR Dante to 2-Channel Party-Line Intercom Interfaces – which are Dante-native – are also used to allow two-way communication.

In total, Lestochi said there are roughly 60 Dante devices in use in the production – and on any given day, multiple productions can take place with around 100 Dante signals running across the local network.

Working from home

That covers the on-site capabilities. In the University of Miami’s broadcast buildout, Dante is also working from home. Remote announcers have become increasingly common as a result of COVID-19 social distancing and travel recommendations. Lestochi said it’s a practice that many viewers likely don’t even realise is taking place.

The Miami production team’s largest events are men’s and women’s basketball in the winter season – and to produce them, Dante is heading into the home.

Glensound Inferno commentator’s boxes – which are Dante-native kits built specifically for live announcer commentary – are sent to an announcer’s home. The system then interfaces with an in-home Mac computer using Dante Virtual Soundcard and Unity Connect software – which facilitates sending a Dante signal at the highest possible quality over the public internet.

“That setup allows for bidirectional channels and two-way communication,” said Lestochi. “The talent can talk to each other as they watch the game, and the director and producer can also talk with the talent. Without that setup it would be nearly impossible for us to do this. It enables the talent to work the games from their home without much difference in the quality of the broadcast.”

The control room located on the University of Miami campus brings in the audio signal and provides mixing and audio-to-video embedding – using an Evertz Scorpion-4 media processing platform – before sending the final product via a direct line to the university’s production partner.

Lestochi considered what it would require to make the same changes had the university not utilised Dante. “It would definitely be a lot more expensive and require a lot more hardware and cabling,” he said. “And the management of the system, and some of the technical aspects to the audio signals, would be very, very tricky if we were doing this with copper. It would likely be far too complex to feasibly do.”

Lestochi said with Dante, not only were changes made rapidly and affordably, but the system allowed for considerations on how to best manage the increasingly remote nature of the work. For example, Lestochi said he can log in to a university system remotely from his house and quickly make a change on Dante Controller software to ensure the system is working effectively.

“It’s those little moments in the process where you realise how much you’ve gained with Dante,” he said. “All of it comes down to confidence. And we have a lot of that right now with our system.”
