C2.6

Quiet Strength. Endless Reliability.

Description

Solid foundation for everyday systems—the CELTO C2.6 provides a genuine 2× 400W 8Ω / 2x 600W 4Ω With smooth, musical delivery in a classic 2U design. This 2-step Class H amplifier excels in small to medium installations and portable setups with consistent performance. Low-noise preamp with PeakStop Opto-Limiter ensures clean signal path and speaker protection without coloration. Comprehensive safeguards including soft-start, short-circuit, and thermal protection keep operations worry-free. Front-to-back cooling with temperature-regulated fans maintains stability even under heavy load. NEUTRIK XLR inputs/links, NEUTRIK SpeakON outputs, plus binding posts offer flexible connectivity. At 14 kg, it's built like a tank yet remains manageable for mobile use. The C2.6 proves that sometimes the quiet, dependable option is the smartest choice in the rack.
