Chris Stapleton, Meghan Trainor and KISS were just a few of the highlights on the outdoor Grandstand stage at this year’s Great Allentown Fair, a week-long annual event owned and operated by the non-profit Lehigh County Agricultural Society for over 150 years. At this year’s fair, Duttera Sound Services, which has been supplying production sound and lighting on the Grandstand for more than a quarter-century, once again provided a QSC WideLine Series Line Array Loudspeaker system, comprised of a mix of WideLine10 and WideLine 8 arrays, powered by PowerLight 3 Series amplifiers.
