CROWN DCi 4|1250 - Four-channel analog power amplifier, 1250W @ 4Ω, 70V/100V

CROWN DCi 4|1250 – Four-channel analog power amplifier, 1,250 W @ 4 Ω, 70 V/100 V

The CROWN DCi 4|1250 is a professional installation amplifier delivering four independent 1,250W channels into 4 Ω and the same power in constant voltage mode (70Vrms and 100Vrms) without the need for external transformers. Housed in a 2U chassis, it combines patented DriveCore™ technology with a high-performance universal power supply and variable speed forced cooling to maximize energy efficiency and minimize noise. With balanced analog inputs with priority switching, optional BLU-Link™ digital transport, and remote control via HiQnet™, it provides unmatched flexibility and reliability for fixed installation projects.

Main features

• Power per channel: 1,250 W @ 4 Ω; 1 250 W @ 70 Vrms; 1 250W @ 100Vrms
• True Rack Density: four high-power channels in just 2U height
• Hi-Z/Lo-Z selection: constant voltage or low impedance, channel by channel via DIP switch
• Bridgeable: Combine channel pairs even in 100 Vrms subwoofer mode
• Inputs: 4 × balanced XLR with priority routing; BLU-Link™ digital over Cat5e
• Control and monitoring: HiQnet™ TCP/IP for remote diagnostics, presets and adjustments
• Universal power supply: 100–240 VAC with active power factor correction (PFC)
• Efficient cooling: front-to-back flow with variable speed fans

Product benefits

• Optimized space: high channel density reduces rack and infrastructure costs.
• Savings on wiring: 70V/100V mode allows the use of smaller cross-section cables and simplifies wiring.
• High reliability: automatic power switching and intelligent cooling for continuous operation.
• Digital Integration: Optional BLU-Link™ and HiQnet™ facilitate scalable, centralized audio networks.
• Advanced configuration: Integrated DSP (limiters, EQ, crossover, delay and matrix) without additional hardware.

Use cases

• Soundproofing of areas in hotels, shopping centers, and airports.
• Corporate AV installations and conference centers with multiple zones and source switching.
• Public address and background music systems in auditoriums, theaters, and educational centers.

Frequently Asked Questions

• How do you choose between 70 V and 4 Ω modes? Via rear DIP switches, channel by channel, without the need for transformers.
• Can I bridge channels together? Yes; channel pairs are bridgeable even in constant voltage mode.
• What operating temperature does it support? Front-to-back vented design with variable speed control for demanding environments.
