Celto Acoustique SD12000

Description Ultimate quad density—the CELTO SQ12000 unleashes 4× 1800W 8Ω / 4x 3000W 4Ω for the most demanding array drives. When maximum per-channel output in 1U is required, this is the answer. Ultra low depth chassis (421 mm) and only 10kg still accommodates extreme power reserves without compromise. The exclusive Virtual Class-A circuit reaches warmth and precision audiophile tonality.. Same audiophile circuit and protection as series, scaled for extreme duty. NEUTRIK SpeakON outputs ensure secure high-current delivery. For systems that refuse to run out of headroom. The SQ12000 redefines what's possible in compact quad amplification.
