The recent Passion 2020 Conference, which hosted more 65,000 attendees at the Mercedes Ben Stadium in Atlanta, saw lead audio engineer Stephen Bailey put Waves’ eMotion LV1 Live Mixer and Waves SuperRack to good use alongside ten Waves SoundGrid recording systems for the three DiGiCo networks on site.

‘The DiGiCo systems were deployed in a festival configuration, with two artist loops and a production loop,’ he explains. ‘Our primary recording system used a DiGiGrid MGR per each artist loop and a DiGiGrid MGB for the production loop, pulling audio and clock off the Madi Main outputs on each DiGiCo SD rack. Each DiGiGrid unit then hit its own Netgear ProSafe M4100-D12G 12-port Switch, which got the SoundGrid network onto single-mode fibre cable, and made its way about 100m outside, to one of the TV trucks where an engineer was managing our primary recording computers.

‘The fibre routes were bookended by the same Netgear switches in the truck, where our engineer had three MacBook Pros running a Waves SuperRack SoundGrid host application to manage these networks. He had a DiGiGrid D on each network locally, to input monitor the audio from Waves’ Tracks Live DAW over headphones.

‘We were also able to throw together rough mixes and output this from the DiGiGrid D to the truck speakers from Tracks Live, while recording in real time to make sure that what we were recording was clean, and also so the producers from the record label could determine if any changes from stage were needed. Our primary recording engineer was also archiving the recorded files and uploading them to Dropbox with a dedicated uplink computer, so after each session of the conference our film and other creative teams could immediately access and pull down audio to use for various exported content without having to ask our audio team.

‘Our secondary recording system was located under stage next to the DiGiCo SD racks,’ he continues. ‘Nearly being a carbon copy of the primary recording system (minus the fibre run and extra switches), this system pulled audio off of the SD racks via the Madi Split Mains. With having SD12 consoles for Broadcast on each loop, each having two Waves DMI cards, we were able to send copy audio routes from the SD racks out of those, and straight into a MacBook Pro at each desk recording into Waves Tracks Live for a very simple, cost effective third redundancy.’

A Waves eMotion LV1 Live Mixer was also used for audience mics placed around the stadium, via three DiGiGrid IOX units located house left, house right and FOH.

‘These units were connected to the truck on the same tac-fibre as the primary recording system, where the LV1 engineer managed, mixed and recorded these mics.’ Bailey says. ‘ISOs of these audience mics were returned back into the DiGiCo SD racks via analogue audio out of a pair of DSPRO StageGrid 4000 SoundGrid stageboxes for recording purposes, and a stereo mix of the audience mics was sent to the broadcast console on the production loop, where it was blended in with the broadcast program audio. What’s great about the eMotion LV1 Mixer are its small footprint, processing power and flexibility, and most significant, the ease of tying all these systems together.’
