SIVision’s three-axle HD OB truck hits the road

Based in Munich, Germany, SIVision’s new HD OB truck recently underwent a successful trial by fire at the Red Bull Air Race, an extreme air racing event held above Budapest, Hungary. The truck’s conceptual design and internal layout are unique in its market: The trailer, with three steerable axles, can be expanded on either side by one single and one double movable sidewall, increasing the width to more than 18ft. In its expanded position, up to 20 workplaces are available inside, including two in the sound control room.

When specifying equipment for the sound control room, only one mixing console came up for SIVision’s consideration — the mc²66 from Lawo. For Imre Sereg, SIVision’s owner and CEO, two factors were of vital importance: the operating philosophy and system reliability.

SIVision’s mc²66 is fitted with 56 faders in a 24 x 8 x 24 frame. It has 192 DSP channels and the router cards each provide 8192 cross points. Twenty MADI ports and 128 AES inputs and outputs are available for external interfaces. Three stageboxes facilitate the direct connection of audio data via optical fiber. Video equipment in the OB truck includes 24 Sony cameras (two with super slow motion), Sony monitors, Sony video consoles and a Harris video router. Though packed with high-tech gear, the internal layout of the 40T truck still offers sufficient space for the entire production team.
