A Renkus-Heinz PNX102/LA line array delivers commentary loud enough to be heard over the ear-splitting sound of engines roaring at Europe’s first drag racing track to be accredited by the American-based National Hot Rod Association (NHRA). Located in Tierp, Sweden, the long U-shaped arena is built on an old military airfield. The brainchild of Lief Andréasson, the derelict patch of perfectly level wasteland has been turned into one of the most modern drag racing arenas in the world featuring 2.51km (1.56 miles) of motorsport racetrack just 120 km (75 miles) north of Stockholm with the capacity for 20,000 spectators. "We've built one of the best race tracks in the world," said Tierp Arena co-director Lars Erik Lindberg, "The reason it's one of the best is simple: the track is concrete so it's really flat and stable; not so sensitive to weather or temperatures. Modeled on Formula 1 tracks, it now has one of Sweden's longest straights, plus open hairpins and very fast corners.” With vehicles reaching speeds of up to 530 km/h (330mph), the commentary needs to be even louder, said Karl-Gustaf Kahlau, of Renkus-Heinz Sweden distributor Luthman SMTTS AB, "so the audience can hear what the commentator is saying above the noise of the cars. What they've done at Tierp Arena is to use line array modules that are powerful enough - but compact enough not to obscure sightlines. When the audience is watching a race, they obviously don't want a bulky sound system in the way.” The PN102/LAX system was simulated in EASE which, using just two dual line array clusters, demonstrated a delivery of 105 dB at the farthest positions. "With our help, they decided on low profile PNX102/LA line array modules, 24 boxes in total, bolted in pairs to customized steel ground frames to make 12 independent freestanding clusters, that they could place along the length of the racetrack at ground level pointing upwards towards the audience. The installer, Mr Lennart Johansson, designed a semi modular, semi mobile transportation and multi-angle cabinet suspension system that was really well thought out and robust enough for our extreme weather conditions - up here it gets both pretty cold in winter and hot in summer; you have to be well prepared. The line array modules are powered by high efficiency Powersoft amplifiers, and a PreSonus StudioLive 16:0:2 digital console adds both live and recording capabilities to the system. www.renkus-heinz.com
