107th IOC Session - LA84 Foundation

competition venues where information needed
to be relayed over a wide area. Painstaking research
carried out in the early stages of the development
of the audio system led to the
development of waterproof minispeakers which
would function even at temperatures of –20˚C.
These speakers were tested in harsh weather
conditions at the alpine skiing and cross-country
venues with outstanding results. Sets of giant
speakers were installed at the finish areas to enhance
the thrill of the competition. On the alpine
skiing courses, an optical transmission system
was utilised for remote control of processors installed
at various points within the venue. This
ensured that there was no loss in the quality of
sound being transmitted over long distances.
All efforts were made to ensure that construction
work was kept to a minimum. For example,
the use of corrugated cables designed to
precise specifications reduced the amount of
cable laid underground to a minimum, and
speakers were arranged to limit disturbance
caused to the surrounding environment. In total,
600 speakers were installed.
