Two into one for Nigerian OBs

The second of two HD outside broadcast units built for SuperSport in Nigeria by UK integrator C2S Systems is due to be shipped this month and will be used for 5.1 coverage of football, writes Kevin Hilton. HD OB3 features a Lawo mc²56 digital desk and will join OB1, which houses a Yamaha M7CL. Each near-identical unit is in fact two trucks, which are linked together on location to provide full OB facilities. The first of the trucks is a single-expanding side chassis and operates as the production area including EVS Replay and audio areas, while the other houses the vision control, technical racks, uplinks and engineering department. With its 48-channel M7CL, HD OB1 (pictured) has been normalised for stereo but features a 5.1 capable infrastructure. C2S’ systems manager Jonathan Lyth comments that if this upgrade is done the Yamaha can be changed for a Lawo desk with only a few days wiring work necessary. Lyth adds that OB3 is “5.1 from the outset” and is due to go into operation during December. He says the two truck approach was taken because the condition of Nigerian roads does not suit long articulated vehicles. Each unit features two Snell (formerly Pro-Bel) Pyxis routers for audio. One operates as a four in, four out 64-channel MADI codec, while the other operates as the main 544×544 mono cross point for AES/MADI/analogue. MADI is a key part of connecting the individual trucks to make a single production scanner. Lyth comments that this was “one of the most complex trucks we’ve worked on” because of the need to join the vehicles together. Other equipment in both units includes three Telex Cronos intercom systems, CTP Systems DBC24 camera talkback routers, three Bel Digital Audio BM-A2-E8SHD+ 2U monitors for de-embedding 3G, HD and SD/SDI video and AES multi-channel audio, as well as decoding Dolby E and Dolby Digital, and eight Bel BM-A2-4SHD audio monitoring units and a range of Canford manufactured products including rack-mount impedance converters, audio line isolators, multiple 3G HD BNC and MUSA panels, digital audio panels, connectors and patch cords. www.c2ssystems.com
