2 Channel Feather Weight Revolution
Description
Efficient stereo powerhouse—the CELTO SLD3000 delivers 2× 1000W 8Ω / 2x 1500W 4Ω / 2x 1500W 2Ω in an ultra-light 4kg 1U package. Perfect entry into high-density amplification for portable rigs and fixed installs needing serious drive without the bulk. TrueSound Class D topology with >50 V/µs slew rate and >2500 damping factor offers pristine control. Studio-grade preamp with MUSE® capacitors and transparent J-FET limiters preserve every nuance. The exclusive Virtual Class-A circuit reaches warmth and precision audiophile tonality. LLC resonant PULSAR SMPS with active PFC ensures stable operation worldwide (90–260 VAC). REAN connectors and comprehensive protection make it road-ready out of the box. Shallow 242 mm depth fits even the tightest racks. The SLD3000 proves that big power can travel light—and sound incredible doing it.
