Crown DCI4X1250 Analog Power Amplifier

The Crown DCI4X1250 is a professional-grade analog power amplifier built for live sound engineers and touring operations. Its compact 2RU rack-mount form factor packs serious output density without hogging rack real estate, while the universal power supply with Power Factor Correction handles any venue's electrical infrastructure worldwide. This is a no-nonsense amplifier engineered to push clean power through complex signal chains with transparent response.

Power Output & Headroom

Delivering 1250W per channel at 8 ohms across all four channels, the DCI4X1250 provides ample headroom for peak transients and sustained high-SPL reinforcement. Bridge mono operation yields up to 2500W, giving you the flexibility to reconfigure channels on the fly for different venues and speaker topologies.

Audio Performance & Signal Integrity

A signal-to-noise ratio exceeding 108dB and 0.35% THD deliver transparent amplification with inaudible noise floor and minimal distortion artifacts. The damping factor greater than 1500 (20Hz–100Hz) keeps speakers locked tight and responsive, while frequency response of ±0.25dB (8Ω, 20Hz–20kHz) maintains flat, predictable response across the audible spectrum—essential for reliable live sound.
