the three- and two-way installation ranges, QX and MK, representing “the vast bulk of our stadium installations”, says Rocha. He adds: “QX Series systems deliver the output and pattern control to cover large areas from distant locations, which is the primary challenge, and designers can choose from several coverage patterns. The MK Series works well for shorter throws and offers even more coverage patterns.” Durability in what may be a wide variety of weather

The pairing of QSC Q-Sys and CX amplifiers, says the manufacturer’s director of engineered systems, Scott Kalarchik, is a common one in its stadium installs these days. The point is underlined by a recent installation at Germany’s Sparda Bank Stadium, which is arguably best known as the home ground of the Offenbach Kickers football club. Selected for reasons including its ease of integration, the Q-Sys platform provides audio management throughout the stadium, while amplification is courtesy of QSC PowerLight and CX amplifiers.
