Madrid, Spain (November 23, 2005)–The technical implementation for TV broadcast of the recent European motocross event, “X-Fighters,” proved to be the precursor for future broadcast concepts regarding super events. Produced in HD and 5.1, the signals were sent in the simulcast technique to TV stations in 10 countries, live to the internet and to selected cinemas in Austria, Ireland, Poland and Spain.
A flight case surround control room for the IT sound mix was installed for giving the viewers a direct impression of the event. Over 150 signal sources were pre-mixed with over 100 effect microphones by five sound engineers using the automation of Lawo’s mc_66 in surround 5.1, whereas in the main OB van (Alfacam OB11 with Nova73 HD system) only the commentators’ voices in different languages were added.
In front of an audience of 25,000 people in the bullfight arena, Las Ventas, in Madrid, the world’s 12 best motocross specialists were involved in a “fight” for rating points given by the referees. For catching the atmosphere and tension of dramatic mid-air acrobatics, these moments were documented with an elaborate microphone positioning at the four jump ramps and the runways over a GPI-controlled sequencing that was initiated by two operators with specially developed remote controls.
The respective microphones were pre-mixed with the audio-follows-video automation and were included as group signals into the mix. Harmonizing the direction of motion with the picture of the currently active camera was acheived by analyzing the tally contacts of the video mixer and establishing assignments via the events in the console to the microphone pre-selected in this instance.
Three remote Dallis frames were linked via optical fiber and connected port-redundantly to the Nova73 HD. The connection with the Nova73 HD system of the OB van was also established via MADI, which minimized the cabling. For a DVD production after the event, a 48-track machine was also redundantly linked. For using the six Tascam DA98HR recorders, MADI converters and Steinberg’s Nuendo HD system, one MADI-PCI card was used. An Orion compressor of Jünger was also integrated.
One essential advantage of this infrastructure was the forceful redundancy concept for reaching the maximum possible operating reliability. With this goes the fast access and the fast reaction time on unforeseen events: all sources could be assigned and measured freely. Moreover, the operating console with 16+8+16 faders via 12 banks could manage this large number of signals in a clear way. The mentioned audio-follows-video automation made the many simultaneous fades despite the fast sequence changes possible, and facilitated the sensible use of sub-layers.
