It’s been a sporty summer of SAM64 for 4HM, as the company’s SDI to MADI/AES audio interface played a part in broadcast systems for the US Open tennis championship and the London 2012 Olympics and Paralympics. At the US Open in New York, a pair of SAM64 units formed part of a fly-away system used in the International Broadcast Centre where eight SDI feeds were routed to the two units, with the de-embedded audio being fed to a Yamaha mixing console. During the London 2012 Olympic Games, several devices were used as the primary de-embedder within the International Broadcast Centre’s system feeding 64 channels of MADI output streams directly to the router in the core of two Lawo mc²66 audio desks. “The SAM64 is an easy and convenient way to get Unilaterial and Host Feeds to Audio as we were receiving all incoming feeds via SDI. We use MADI streams because it is the tidiest way to get large amounts of audio into the Lawo desks,” said Paul Sykes, project manager for the Olympics and Paralympics. “As a 1U device it is compact which is essential on remote operations and it provides the most convenient and simplest way to access the SDI streams. Having two Lawos running from the same core meant that we could then just split the MADI feeds into both desks. There is also so much choice in ways to clock the units that synchronisation was never an issue.” Thes US Open and the London 2012 weren’t 4HM’s first major sporting events; SAM64s have already been deployed at the Australian Open tennis championship, the UEFA European Football Championships in Poland and Ukraine, and the FIFA World Cup in South Africa. www.4hmbroadcast.com
