Overview
The Celto Pro SQ12000 is a four-channel power amplifier designed to deliver exceptional power density and pristine audio quality within a single rack unit (1U). Engineered for demanding professional audio installations and touring applications, it delivers 1800W RMS per channel at 8 Ohms and 3000W RMS at 4 Ohms, reaching a total capacity of 12 kW.
The proprietary 4th generation high-speed, high-current discrete Class D output stage operates at an impressive 92% efficiency. Its preamplifier stage features ultra-low noise circuitry equipped with MUSE® Fine Gold capacitors and TrueRMS JFET VCA limiters to ensure maximum signal integrity. The switch-mode power supply with active PFC (Power Factor Correction) guarantees stable operation across universal AC inputs from 90V to 260V. Weighing only 10 kg, the SQ12000 features Neutrik XLR inputs and SpeakON outputs, representing a robust and reliable engineering solution for high-end acoustic projects.
