CROWN CDi 4|600BL - Analog input amplifier + Blu Link, 4 channels, 600W per output channel

CROWN CDi 4|600BL – Analog input amplifier + BLU Link™, 4 channels, 600 W per channel

The CROWN CDi 4|600BL is a high-density professional installation amplifier delivering 600W continuous per channel into 4 Ω (300W @ 2 Ω; 600W @ 8 Ω; and 600W bridged) and delivering up to 100Vrms directly without the need for external transformers. Based on DriveCore™ technology, it features a powerful 32-bit/96kHz DSP with input router, input delays up to 1000ms and 100ms output, 8-band parametric EQs, a crossover, and the LevelMAX™ limiter suite for speaker protection. Thanks to HARMAN’s BLU Link™ digital bus, it can send and receive up to 256 channels of low-latency audio over Cat5e cable, while monitoring and remote control are handled via HiQnet™ TCP/IP.

Product benefits

• High power density: Four 600W channels in just 2U of rack space free up space for other equipment.
• Full Digital Integration: BLU Link™ and HiQnet™ unify audio transport and control on the same network.
• Quick Setup: JBL and DSP presets accessible from the front panel or Audio Architect software.
• Intelligent Protection: LevelMAX™ limiters and priority router safeguard your speakers.
• Silent operation: proportional ventilation that adjusts speed according to load.

Use cases

• Sound reinforcement for medium-sized movie theaters, churches, bars, and lounges.
• Corporate and commercial facilities with multiple zones and compact racks.
• Digital audio distribution in venues with existing Cat5e cabling.

Frequently Asked Questions

• Does it require transformers for 70V/100V? No; it delivers constant native voltage without additional transformers.
• How do I adjust the DSP? From the front LCD display or HiQnet™ Audio Architect software.
• What is the latency of BLU Link™? Less than 1 ms, ideal for precise synchronization across multiple channels.
