Overview
The Celto Pro SD7000 is a professional power amplifier that combines high power density with a compact form factor. Measuring just 1U in height and weighing 6 kg, this unit delivers an impressive RMS output of 2000W per channel at 8 Ohms, 3500W at 4 Ohms, and 4000W at 2 Ohms.
In bridge mode, it reaches up to 7000W at 8 Ohms and 8000W at 4 Ohms. At its core is a proprietary 4th generation discrete Class D output stage operating at 92% efficiency. The preamplifier stage features MUSE® Fine Gold capacitors and TrueRMS JFET VCA limiters, ensuring ultra-low noise and distortion for pristine audio reproduction. The switch-mode power supply with active PFC (Power Factor Correction) guarantees stable operation across universal AC inputs from 90V to 260V. Thermal management is handled by temperature-regulated brushless fans with front-to-back airflow. Equipped with Neutrik XLR inputs and Neutrik SpeakON NL4MP outputs, the SD7000 is engineered to deliver reliable, high-fidelity performance for both demanding touring environments and permanent venue installations.
