Overview
The Celto Pro SQ8800 is a 4-channel power amplifier engineered to deliver high power density and pristine audio quality within a compact 1U chassis. Delivering 1300W RMS per channel at 8 Ohms and 2200W RMS at 4 Ohms, it is built to withstand the demands of both touring and permanent installations.
The proprietary 4th generation discrete Class D output stage operates at 92% efficiency, paired with an active PFC switch-mode power supply supporting universal AC input (90-260V). Its preamplifier stage utilizes MUSE® Fine Gold capacitors and TrueRMS JFET VCA limiters to ensure ultra-low noise and natural sound reproduction. Weighing only 6 kg, the SQ8800 features Neutrik XLR inputs and SpeakON outputs for secure, professional connectivity.
