CROWN DCi 8|300N - Eight-channel power amplifier, 300W @ 4Ω with Blu Link, 70V/100V

CROWN DCi 8|300N – Eight-channel power amplifier, 300 W @ 4 Ω with BLU-Link™ and 70 V/100 V

The CROWN DCi 8|300N is a high-density professional installation amplifier delivering eight independent 300W per channel into 4Ω and supporting 70V and 100V constant voltages without the need for external transformers. Based on DriveCore™ technology, it combines over 90% efficiency with a 2U chassis, allowing high power to be integrated into small spaces. It features BLU-Link™ digital audio transport for up to 256 low-latency channels over Cat5e cable, and features balanced analog inputs with a priority router that automatically switches over if the main signal fails. Its onboard DSP includes LevelMAX™ limiters, input and output parametric EQs, crossover, delay, and signal generator for fast, fine-tuning, with pre-loaded JBL presets for quick commissioning. The HiQnet™ over TCP/IP protocol and programmable GPIO ports allow remote monitoring and control of the system, while its variable-speed forced cooling ensures quiet and reliable operation even under maximum load.

Product benefits

• High power density: eight channels in just 2U, ideal for compact racks.
• Digital Integration: BLU-Link™ and HiQnet™ make audio transport and remote control easy.
• Quick setup: DSP with JBL presets and front panel allow configuration without additional software.
• Continuous reliability: DriveCore™ and active PFC reduce consumption and heat generation.
• Silent operation: Variable ventilation keeps noise levels low in critical environments.

Use cases

• Multi-zone audio distribution in auditoriums, theaters, and convention centers.
• Public address and voice evacuation systems in airports, hospitals, and hotels.
• Commercial and corporate facilities with centralized control and networked audio.

Frequently Asked Questions

• How does BLU-Link™ work? It transports digital audio and DSP data up to 256 channels over Cat5e cable with minimal latency.
• What happens if the analog signal fails? The priority router automatically switches to the secondary input.
• Can it operate in bridge mode? Yes; channel pairs are bridgeable to deliver 750 W @ 4 Ω or 900 W @ 8 Ω.
