Lawo mc²96 Console Mixes Rock in Rio Festival

The recent Rock in Rio festival in the Barra Olympic Park held in Rio de Janeiro, Brazil, was broadcast live on Globosat and mixed live on a Lawo mc²96 Grand Production Console. It represented the first time a Lawo mc²96 console was used for such a large-scale music concert.

With an audience of 45 million viewers in 15 million households across Brazil, Globosat is the largest pay TV operator in Latin America. Its use of the mc²96 console was part of a rental package of equipment, support and training provided by Lawo for the event.

Rock in Rio ranks as one of the largest music festivals in the world. This year’s massive festival was staged over ten days (Sep 15 – Sep 24, 2017) in the Barra Olympic Park in Rio, and included Guns N’ Roses, the Red Hot Chili Peppers, Bon Jovi, Aerosmith, Justin Timberlake and Maroon 5 headlining on the Palco Mundo stage, with Sepultura, Ceelo Green, and Nile Rodgers and Chic among those appearing on the Sunset stage.

Through Latin American system integrator and Lawo partner LineUp Broadcast Systems, Lawo provided Globosat with a 40-fader mc²96 fitted with Ravenna, AES and MADI Cards, along with a Sample-Rate Converter and a Compact Core for the console. The console was integrated with a Lawo Nova73 Router using RAVENNA audio networking. The setup took advantage of a legacy Globosat structure resulting from the company’s involvement in the Summer Olympics broadcast from the Barra Olympic Park in 2016.

Gabriel Thomazini, Coordinator of Audio at Globosat, said that for the Rock in Rio festival, they developed a specific workflow with a remote mixing room at its headquarters, some 14 km (about 8.6 miles) away.

“We received 128 input channels from the Mundo stage and 64 from the Sunset stage,” Thomazini said. “We chose which stage we wanted to mix just by changing productions. For transport, we used Lawo V_link [video-over-IP transporters] and RAVENNA-based streams.”

Lawo’s V_pro8 8-channel video processor was used to provide HD SDI to a Blackmagic Design HyperDeck Shuttle SSD recorder and the system’s embedder.

“Rock in Rio gave us our first opportunity to mix with the new mc²96 Grand Production Console,” Thomazini said. “It is based on the same system as mc²36 and mc²56 MkII, but adds interesting possibilities to work with immersive audio formats, like Dolby Atmos. We are mixing in 9.1 (5.1.4) to deliver immersive content and this console has the necessary flexibility to configure specific monitoring paths from the encoder outputs, for example. We can check the results after encoding in 5.1.4, 5.1 and stereo, just configuring a user button. The mc²96 has several improvements with a dedicated monitoring section and Up/ Down control of 3D panning.”

The Globosat setup also used a pair of Sound Devices model 970 64-track Dante and MADI-equipped multitrack audio recorders. Audio monitoring was taken care of by a Genelec system. “Our monitoring system is based entirely in coaxial speakers,” Thomazini explains. “We are using four new Genelec 8341A monitors for height information and a 5.1 system, comprised of 8351A speakers and one sub. We’ve aligned this setup with the new version of [Genelec Loudspeaker Manager] GLM 3.0 software.”

Supporting an immersive approach to the broadcast sound mix for Rock in Rio, Globosat also received support from Sennheiser, which helped pick up crowd noises with its Esfera microphone systems and the new Cube setup from the 3D Ambeo concept.
