Overview
The Celto Pro SLQ4800 is a professional 4-channel power amplifier designed for demanding audio applications, packing immense power into a 1U rack space weighing just 4.5 kg.
Delivering 950W per channel at 8 ohms and 1200W at both 4 and 2 ohms (bridgeable to 2x 2400W), it features a proprietary 4th-generation discrete Class D output stage operating at 92% efficiency. Equipped with a switch-mode power supply featuring active PFC (90-260V), it ensures stable performance worldwide. The preamplifier stage utilizes premium MUSE® Fine Gold capacitors and TrueRMS JFET VCA limiters to achieve ultra-low noise and distortion. Featuring professional REAN XLR inputs and SpeakON outputs, the SLQ4800 is the ultimate lightweight solution for touring and high-end fixed installations where sonic purity and reliability are paramount.
