CROWN DCi 4|2400N - Four-channel power amplifier, 2400W @ 4Ω with Blu Link, 70V/100V

CROWN DCi 4|2400N – Four-channel power amplifier, 2400 W @ 4 Ω with BLU-Link and 70 V/100 V

The CROWN DCi 4|2400N is a high-performance installation amplifier based on DriveCore™ technology, delivering four independent channels of 2400W into 4Ω and constant voltage outputs of 2100W at 70Vrms and 2300W at 100Vrms without the need for external transformers. It features Harman’s BLU-Link™ digital audio bus for carrying up to 256 channels with low latency, along with balanced analog inputs and a priority router that automatically switches between sources in the event of a failure. Its HiQnet™ over TCP/IP protocol enables remote monitoring and control, and programmable GPIO ports offer flexibility for volume control, preset recall, or error signaling. In addition, it integrates an advanced DSP with LevelMAX™ limiters, input/output EQs, crossover, delay, matrix mixer, and speaker line monitoring.

• Cooling: Variable speed forced ventilation, front-to-back flow

Product benefits

• High rack density: Four 2400W channels in just 2U, optimizing space and infrastructure costs.
• Low Latency Digital Audio: BLU-Link™ ensures quality and synchronization in large installations.
• Signal redundancy: Priority router with automatic switching ensures audio continuity.
• Centralized control: HiQnet™ and GPIO ports facilitate remote monitoring and management of multiple amplifiers.
• Energy efficiency: DriveCore™ and PFC reduce power consumption and heat dissipation.
• Full Processing: Advanced DSP for fine-tuning the system without additional hardware.

Use cases

• Public address and background music systems in hotels, offices, and businesses.
• Corporate AV installations and conference centers with zoning and source switching.
• Movie theaters, auditoriums, and multipurpose spaces that require networked digital audio.

Frequently Asked Questions

• How does BLU-Link™ work? It carries high-quality audio and DSP over Cat5e cable, allowing up to 256 channels with minimal latency.
• What happens if the primary source fails? The priority router switches to the secondary source in real time.
• Is a transformer necessary for 70V/100V? No; the amplifier delivers constant voltage directly.
