Crown CDi4x600BL 4x600 Power Amplifier with BLU link
Description
Crown CDi4x600BL 4-Channel Power Amplifier with BLU Link
The Crown CDi4x600BL is a professional-grade 4-channel power amplifier engineered for live sound reinforcement, touring rigs, and permanent venue installations. Its compact, rack-mountable chassis delivers 600 watts per channel with the reliability and low-distortion performance that Crown has built its reputation on, while integrated BLU Link networking enables seamless digital control and configuration—critical for sound engineers managing complex systems from FOH or during load-in.
Power & Output Flexibility
This amplifier delivers 600 watts per channel at 4 ohms across all four channels simultaneously, with dual output modes supporting both 4/8 ohm speaker loads and 70/100V distributed systems. The ability to drive 100Vrms speaker loads without a transformer eliminates a common integration bottleneck and simplifies system design for both portable rigs and fixed installations, giving sound crews the flexibility to adapt to any venue or configuration.
Audio Performance & Control
The CDi4x600BL maintains a flat frequency response of ±0.25dB from 20 Hz to 20 kHz with a damping factor exceeding 1000, ensuring tight bass control and accurate reproduction across the full spectrum. Built-in DSP processing includes parametric EQ, crossover functions, dynamic limiting, and speaker tuning tools—all manageable via BLU Link for remote adjustment during soundcheck or live performance without needing physical access to the amplifier.

Frequently Asked Questions
What does BLU Link do, and why does it matter for my installation?
BLU Link is Crown's digital networking protocol that lets you control and configure the amplifier remotely—adjusting EQ, crossover, limiting, and speaker tuning without physical access. This simplifies setup in complex commercial and live systems where the amp may be mounted in a ceiling, wall, or distant rack.
Can this amp drive 70V or 100V distributed speaker systems?
Yes. The CDi4x600BL supports dual output modes including 70/100V distributed audio and can drive 100Vrms speaker loads directly without an external transformer, eliminating a common integration bottleneck.
What built-in DSP processing does it include?
The amp includes parametric EQ, crossover functions, dynamic limiting, and speaker tuning tools—all accessible and adjustable via BLU Link, reducing or eliminating the need for external signal processors.
What is the frequency response and damping factor?
The frequency response is flat at ±0.25dB from 20 Hz to 20 kHz with a damping factor exceeding 1000, ensuring tight bass control and accurate, transparent reproduction across the full spectrum.
How much power does each channel deliver?
Each of the four channels delivers 600 watts at 4 ohms, with the ability to run all four channels simultaneously at rated power into 4/8 ohm speaker loads or 70/100V distributed systems.
