Broadcast coverage of the imminent London 2012 Olympics will involve a wide range of equipment and technology, from big mixing consoles and routers to conversion interfaces like the 4HM SAM64, writes Kevin Hilton. Facilities company Presteigne Charter will use the SDI to MADI and AES box for broadcasts during the Games by Australian broadcasters Foxtel and Channel 9. Presteigne Charter was the first buyer for the SAM64 (pictured) in 2010 and used it during that year's World Cup in South Africa. Recently the company has installed the unit, which can extract 16 audio channels from four SDI inputs, for the World Swimming Championships and at Grand Slam tennis tournaments. The SAM64 was produced by 4HM to fulfil a perceived need for a cost-effective de-embedder in audio for picture production. Company director Barry Revels says sports broadcasting was a major consideration in designing the product and it is now meeting a demand (see feature for full interview). According to Steve Kilsby of Presteigne Charter the quiet running of the SAM64 means it can be positioned in operational areas. Commenting on the Olympics projects, he says, "For Channel 9 and Foxtel we will use the interface functions to supply our main studio mixer, a Lawo mc² 66, and the AES outputs for feeding the emergency mixer. The ability to de-embed four HD/SDI signals in 1RU keeps the equipment count to a minimum, which is essential for flyaway work." www.presteignecharter.com
