The AD-C1200 includes coaxial transducers, a transformer and a crossover network factory-mounted on a steel baffle. The baffle is designed to mount to the QSC enclosure AD-C1200BB (available separately) or to any ~2.5' enclosure using industry standard transducer mounting dimensions. High-current, low tolerance network components provide smooth full-range, passive performance. The included 70V/100V custom designed transformer is optimized for low line loss as well as accurate and transparent acoustic performance.
