Description
Flagship punch in the CORE lineup—the CELTO C2.20 unleashes 2x 1200W 8Ω / 2x 2000W 4Ω via advanced Class TD topology for superior efficiency. Engineered for high-output installations and touring systems needing authoritative drive without compromise. Same proven protection and preamp circuit as siblings, now with even greater thermal stability. Linear toroidal PSU and copper heatsink cooling handle sustained high power effortlessly. Full NEUTRIK connectivity and flexible operating modes make integration seamless. At 19.5 kg, it's the heavyweight champion that still fits standard racks. The C2.20 delivers the kind of power that makes speakers thank you—and audiences stay longer.
