Crown CDi DriveCore 4|600: High-Performance Installation Amplifier

The Crown CDi DriveCore 4|600 is a sophisticated 4-channel power amplifier designed for permanent installations in cinemas, hospitality venues, and corporate environments. It utilizes multi-patented DriveCore technology, which integrates hundreds of traditional components into a single tiny chip to increase reliability while maintaining exceptional audio fidelity. This 2RU amplifier delivers 600W per channel into 4 or 8 ohms and can drive 70V or 100V high-impedance loads directly without the need for an output transformer.

Integrated DSP and Network Management

The CDi 4|600 features a robust internal Digital Signal Processor running at 96 kHz with 32-bit floating-point precision. The on-board DSP tools include input routing, crossover filters, an 8-band parametric EQ for both input and output, delay up to 1000 ms, and LevelMAX limiters to protect connected speakers. The amplifier also supports the import of FIR filter coefficients, allowing for high-level custom tuning.

Configuration and monitoring are streamlined through Harman HiQnet Audio Architect software over a standard TCP/IP network. For onsite adjustments, the front panel features a high-contrast multi-colour LCD and an intuitive interface for quick setting changes. Additionally, a combined GPIO/AUX port allows for external control such as preset recall, channel muting, or remote power management.

Reliability and System Protection

Engineered for continuous professional use, the amplifier includes a universal power supply with Power Factor Correction (PFC) for stable performance across 100V to 240V AC inputs. It is equipped with advanced protection circuitry that guards against short circuits, DC faults, overheating, and over/undervoltage conditions. For installations utilizing JBL speakers, the unit comes pre-loaded with JBL speaker tunings, significantly reducing the time required for system commissioning.
