CROWN DCi 4|1250N - Four-channel power amplifier, 1250W @ 4Ω with Blu Link, 70V/100V

CROWN DCi 4|1250N – Four-channel power amplifier, 1250 W @ 4 Ω with BLU-Link™ and 70 V/100 V

The CROWN DCi 4|1250N is a high-performance installation amplifier based on patented DriveCore™ technology. It delivers four independent channels of 1250 W per channel into 4 Ω , as well as the same power in 70 Vrms and 100 Vrms modes without external transformers. It incorporates the BLU-Link™ digital bus for low-latency audio transport and DSP over Cat5e cable, balanced analog inputs with priority router and integrated DSP with LevelMAX™ limiters, input/output EQs, delay, crossover and matrix mixer, all configurable from the HiQnet™ protocol over TCP/IP.

Main features

• Channels and power: 4 × 1250 W @ 4 Ω; equal power at 2 Ω, 8 Ω, 16 Ω, 70 Vrms, and 100 Vrms
• BLU-Link™ digital: Up to 256 audio channels and DSP control over Cat5e
• Inputs: 4 × balanced XLR; priority router for automatic switching in the event of signal failure
• HiQnet™ over TCP/IP: Remote monitoring, preset updates, and upload status
• Programmable GPIOs: 4 ports for volume control, preset recall, or error reporting
• Integrated DSP: LevelMAX™ limiters, EQ I/O, crossover, delay, matrix mixer and test signal
• Frequency response: 20 Hz–20 kHz ± 0.25 dB; THD 0.35% (20 Hz–20 kHz, full power)
• Damping factor: > 1500 (20 Hz–100 Hz)
• Cooling: Variable speed forced ventilation, front-to-back flow; maximum noise 47 dBA at 1 m
• Power supply: Universal 100–240 VAC, 50/60 Hz, active PFC; IEC 20 A connector

Product benefits

• Maximum rack density: 4 × 1250 W in just 2 U of height, optimizing space and infrastructure
• Quality and reliability: DriveCore™ and PFC reduce consumption and heat generation.
• Digital Integration: BLU-Link™ and HiQnet™ facilitate scalable audio networks and centralized monitoring.
• Signal Continuity: Priority router and GPIO ensure seamless switching.
• Advanced Configuration: Full DSP for fine-tuning without additional equipment.

Use cases

• Public address and background music systems in hotels, airports, and shopping centers.
• Corporate AV installations and auditoriums with multiple zones and presets.
• Networked audio projects in theaters, convention centers, and educational spaces.

Frequently Asked Questions

• How does BLU-Link™ work? It transports up to 256 channels of digital audio and DSP with minimal latency over Cat5e.
• What happens if the primary signal fails? The priority router instantly switches to the secondary source.
• Do I need transformers for 70V/100V? No; the amplifier delivers constant voltage natively.
