Los Angeles, CA (May 8, 2014)—Brazil’s outside broadcast company, Mix2Go recently purchased multiple Focusrite RedNet units as part of its wider digital audio/visual network for the broadcast and recording of the 2014 FIFA World Cup Final Draw event.
Mix2Go uses a RedNet 2 16-channel A-D/D-A interface, the RedNet 3 32-channel digital I/O, a RedNet 6 MADI Bridge and three RedNet PCIe cards. For the FIFA World Cup Final Draw, Mix2Go decided its RedNet 2 would deliver the final live mixes to the video OB truck. It also used its RedNet 3 as an additional monitoring reference via the AES/EBU outputs.
The setup for the Final Draw event consisted of a large Dante network that linked two OB trucks parked in different locations outside the venue to the main stage. Two stage boxes (one primary and one backup) were located in the main arena, connected to gigabit network switches using Cat-6 cables. Signals from this stage rig were sent via multi-mode fiber cables to another pair of switches inside the music OB truck, about 150ft (50m) away.
Inside the truck, the fiber signal was converted back to Ethernet and routed to two Mac Mini computers, which handled the multi-track recording, using Pro Tools and Audinate's Dante Virtual Soundcard (DVS) driver. The signals from stage were also routed simultaneously to the live mix console, from where the final broadcast stems were then routed to RedNet 2, located inside the video OB truck, about 100ft (30m) away. Here, the stems were converted to analog then mixed with the rest of the event’s audio and added to the final video feed.
