Anchor the largest install with the most output in the line. The C3600FDi delivers a 2 x 1800 W Class-H output stage and the full C-Series DSP — FIR filters, per-channel PEQ, output delay, and load-impedance monitoring — for rooms where coverage and control both have to be absolute. Direct-drive 70 V/100 V feeds distributed lines straight, deep protection guards every fault path, and three-stage cooling keeps it composed under sustained demand. Large venues, arenas, and multi-zone halls run on it.
