Behind its striking modernist exterior, the City Church of Madison in Wisconsin has a spacious, 800-seat sanctuary with complete stage and A/V production capabilities. Having relied on live stage productions supported by multiple large video projection screens, professional lighting and a full pro-audio-quality sound system for many years, the expanding scope and vision of the church’s A/V productions recently prompted a substantial upgrade including completely new production workflow built upon Dante audio and the new Dante AV networked video platform.

‘We have always believed in using technology to eliminate distractions and deliver our message in a clear, compelling and engaging way,’ says Worship Pastor, Nathan Rohde. ‘We basically just did a complete overhaul of the entire sanctuary so we can now integrate audio and video seamlessly throughout our church, our education facilities and online.’

The church had hit the limits of its existing technology; the production quality in the sanctuary needed improving, and full A/V content needed to be shared more extensively throughout the facility. The church leadership also wanted a better way to bring the same quality of their live productions to their streaming media services.

‘As we researched potential network solutions, we learned about Dante AV and the Dante AV-enabled encoders from Patton. This looked like the direction we needed to go,’ says a Technical Volunteer, Ryan Schaub. ‘The flexible scalability that an AV-over-IP network system offers is light-years beyond analogue cabling. The more we learned about the Dante ecosystem, the more we realised that this is what we needed.’

The Dante platform allows audio, video and control data to be transported over standard 1GB Ethernet. Dante replaces point-to-point analogue and digital connections with software-based routing, while Dante AV provides 4K60 4:4:4 video with ultra-low latency over a 1GB network, synchronised with Dante audio.

City Church Technical Director, Macky Mikunda and his team converted their workflow over to an IP-based Dante AV network. Instead of unplugging and plugging cables into patchbays, they now route all signals using Dante Controller software. What previously took a lot of time to set up, is now done quickly with direct digital network connectivity, rather than chaining systems together and losing signal quality at each step.

Dante-AV Patton encoders are used with all of the church’s SDI cameras and sanctuary projection screens. The video is distributed over the network with Dante Controller perfectly routing synchronised video and audio. Mikunda is now adding decoders for multiple screens throughout the facility so they can deliver live sound, video and graphics simultaneously to multiple areas throughout the church.

‘This was a big change for us – we pulled out almost all of our analogue cabling, upgraded our network switches, and ran a more extensive set of Cat6 cabling to tie all areas together,’ Mikunda says. ‘We then dialled in our network specifics, set the clock-sync settings and the results have been great. We’re now fairly future-proof and will be able to modify or scale our system over the coming years. Ultimately, that saves us a lot of time, money and frustration while improving the quality of our work.’

Regarding the audio, the church’s former production point-to-point analogue system had several limitations. There was a large analogue cable snake running from the stage back to patchbays and into the FOH mixer. Various analogue splitters were used to distribute signals to a limited number of other areas, but everything was essentially isolated to the sanctuary, and all other areas had their own sound systems. Previously, it was a tug of war between the needs of live productions and those of streaming; there was no independent gain or mix control between those two functions, so productions were hard to manage and deliver.

All stagebox and snake cabling has been eliminated and replaced with a single Cat6 network cable. The church was able to keep its existing FOH console by simply adding a Dante card, and kept its existing amplifiers and loudspeakers by using a set of Dante AVIO adapters to distribute audio signals over the network.

‘Our musicians, technicians and the congregation have all noted that everything looks and sounds better,’ notes Sarah Karlen, the Arts and Communications Pastor for City Church. ‘Bringing together all the equipment and systems into a unified platform allows us to focus on the art of the production, not on the issues and limitations of the cable runs or equipment,’ said Karlen. ‘We’re now able to efficiently share our message with more people in a higher quality way, and the Dante platform has made it possible.’
