While the whole of the complex had its audio system updated, the ski slope had a completely new system installed. LBI has extensive experience of using Technomad Vienna weatherproof loudspeakers in harsh environments, such as the decks of cruise ships, and so chose these for the ski slope, as they would be exposed to the snow at all times.
Eight Viennas were used along the length of the ski slope in four positions. Because the sound system has to cover a long, thin area, delay times are unusually lengthy, the longest over a third of a second. LBI also had to experiment with the delay time calculations because of the different speed of sound in sub-zero temperatures. A completely portable audio system for use by DJs was also installed, including Technics turntables, Denon CD players, DAS loudspeakers and a Soundcraft FX8 desk, housed in custom-built racks and flightcases.LBI's job was complicated further by the sound system having to be fully operational by day, despite the refurbishment and replacement work going on at night. The new system uses Yamaha CP2000 amplifiers throughout the complex, with audio processing via BSS MiniDrives. The existing loudspeakers were retained, working in parallel with new Turbosound Impact Series 80 and 50 loudspeakers in the bar and food court areas. A Trantec radio microphone is also routable throughout the entire system using the system’s zoner. The whole installation used 1.2 miles of cable.
