The Crown CDi4x600 is a four-channel digital signal processing amplifier from the CDi DriveCore Series, engineered for high-performance multi-zone sound reinforcement in demanding installed audio applications. This amplifier leverages Crown's innovative DriveCore technology, which integrates the amplifier drive circuit directly into the output stage, resulting in exceptional power efficiency, reduced heat output, and a compact form factor relative to its substantial output capabilities. Each of the four channels delivers 600 watts into a 4-ohm load, providing robust power for distributed speaker systems, monitor wedges, or small arrays in venues such as performing arts centers, large houses of worship, corporate auditoriums, and entertainment complexes.

A central feature of the CDi4x600 is its comprehensive, networkable onboard DSP, accessible via Ethernet and Crown's System Architect software. This integrated processing provides complete control over input routing, crossover filtering with multiple filter types, parametric and graphic EQ, output delay, and dynamics processing including limiters. The amplifier also includes Crown's Intrinsic Correction (IC) presets, which offer optimized voicing for specific JBL and Crown loudspeaker models, simplifying system tuning. This combination of substantial multi-channel power and sophisticated processing within a single unit allows system designers to reduce component count, simplify installation, and centralize control, often eliminating the need for external DSP racks.

Built for 24/7 reliability, the amplifier incorporates advanced thermal management with variable-speed cooling and extensive protection circuitry against all common fault conditions. Its connectivity includes both analog and optional digital audio inputs, along with professional SpeakON and binding post outputs. The Crown CDi4x600 represents a powerful and intelligent solution for system integrators, providing the muscle, flexibility, and control needed to deliver pristine, managed audio across multiple independent zones in large-scale professional installations.
