FIS Nordic Skiing World Championships in Holmenkollen with systems from Electro-Voice
To enhance their appreciation of the competitions as they unfolded, the firm of Scandec Systemer AS was commissioned to install new sound reinforcement systems at the foot of both the large Holmenkollbakken ski-jump and its smaller companion, the Midtstubakken, as well as the Langrennsarenaen, from which the skiing events were observed. In the planning of the sound design, the company based in nearby Kolbotn worked closely with Norwegian television broadcaster NRK to ensure not only that the new system represented a convincing sound reinforcement solution for speech, jingles and music, but also that the loudspeakers did not obstruct lines of sight for the cameras.
In all, some 250 loudspeakers were distributed between the three competition venues. Among them were 56 ZX1i composite indoor/outdoor two-ways and weatherproof representatives of the EVF range in the shape of fifty-one EVF-PIB and the same number of EVF-1121S-PIB cabinets, each equipped with a 12-inch woofer. The criteria determining the choice of speakers were their frequency response, sound pressure levels, coverage patterns and robustness, the extraordinary imperviousness to adverse weather conditions of the Electro-Voice models selected proving one of their trump cards. Electro-Voice power amplifiers with a total output of 120,000 watts RMS were enlisted to drive the speakers, the task falling to thirty-four CPS 8.5 amps. The entire system was controlled by twelve digital signal processors. A fully digital and redundant solution was also found for the signal transmission via Ethernet using the CobraNet protocol.
The installed loudspeakers can be turned on and off individually using touch screens, so the system can be adapted, now that the world championships are over, to future events.
