It belongs to Celto's S Series, built specifically for the demands of live production, and pairs very high power density with the kind of measured performance normally associated with studio equipment.\u003c\/p\u003e\n\n\u003ch2\u003ePower Output\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e4 x 1800W into 8 ohms\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e4 x 3000W into 4 ohms\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e4 x 2600W into 2 ohms\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy It Performs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eActive PFC with resonant SMPS.\u003c\/strong\u003e The switch-mode supply uses active power factor correction, which keeps current draw clean and allows this much output from a 1U chassis without the mains behaviour that plagues conventional designs.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTrueSound Class D output stage\u003c\/strong\u003e using high-speed, high-current MOSFETs.
