Christie Roadsters light up Choranche Cave

France, with over 100 natural caverns, drawing in more than six million visitors every year, is the number one venue for underground tourism in Europe. With such stiff competition, Choranche Cave, located in the heart of the Vercors reserve between Grenoble and Valence, pulled out all the stops to ensure visitors paid to enjoy its tubular stalactites – made from calcium and sometimes called ‘soda straws’ – above all others.

Late 2008, installation and integration expert Système Son, a specialist in distributing, designing, organising, selling and renting out sound and light equipment, won a 200,000 euro tender with its outstanding video projection solutions from Christie – global leader in diverse visualisation solutions.

The display uses two Christie Roadster S+16K projectors equipped with Twist^TM cards. This model boasts SXGA+ resolution (1400 x 1050) and brightness levels of 16 000 lumens. Featuring the 3-chip DLP® technology with 0.95″ DMD chips, the Roadster S+16K offers 90% brightness uniformity and a 1500:1 full field contrast ratio. The Christie Roadster S+16K comes with built-in handles, a new airflow pattern and multi-rigging points. Tipping the scales at a mere 63.5kg, it can be carried by just two people. It is designed for hire and use in any environment, and its 10-bit image processing capability raises the bar for actual image processing, colour accuracy and video realism. The onboard ChristieNET network interface allows for control of all the projector’s functions over a network.
