World Cup Concert Chooses Ravenna and Horus for Broadcast

RIO DE JANEIRO� The World Cup Concert at the HSBC Arena in Barra de Tijuca was broadcast delayed-live to more than 50 countries within hours of finishing. The concert starred Pl�cido Domingo, Lang Lang, Puerto Rican soprano, Ana Mar�a Mart�nez, the Brazilian Symphony Orchestra and Opera Chorus and Paula Fernandes.
Production company Bernhard Fleischer Moving Images tapped Grammy Award-winner Jesse Lewis for the audio production.
Some of the equipment needed to produce the event was shipped from Europe, due to Brazilian import challenges. This included Merging Horus units, which are used to record audio in conjunction with Pyramix.
Production challenges began when Lewis'' flight was delayed, cutting the preparation time in half. Then, the OB van had to be moved an additional 50 meters to accommodate for the 2016 Olympics, extending the copper cable runs to about 100 meters.
Both Ravenna and coaxial MADI were run to provide redundancy, although the Ravenna solution ultimately was the only one that worked.
The Horus enabled routing of the MADI signal in 8-channel blocks to overcome some limitations of the Studer Vista 5 MADI input. The truck was unable to cope with a 96 kHz recording so it was switched to 48 kHz without compromising the final transmission. The two 56-channel coaxial MADI streams from the DiGiCo were fed from the Horus via Ravenna and then to the Studer console on a pair of 64-channel MADI fiber streams allowing the recording of all signals to hard disk. The Pyramix recorders were reliable, and allowed for some remixing prior to the delayed broadcast.
