Crown NCDI4000E60 CDi 4000 Two-channel, 1200W @ 4?, 70V/140V Power Amplifier

Crown CDi Series amplifiers

The Crown CDi Series amplifiers from Crown Audio are engineered for professional installed sound environments that require dependable amplification, flexible configuration options, and consistent long-term performance. The series includes four models—CDi 1000, CDi 2000, CDi 4000, and CDi 6000—sharing the same design platform while differing in output power ratings to suit different system sizes.

Designed for fixed installation use, the CDi Series is ideal for commercial environments such as large venues, houses of worship, hospitality spaces, and distributed sound systems. Each unit combines rugged construction with a lightweight chassis, making it suitable for rack-mounted professional audio setups where reliability and efficiency are critical.

The amplifiers support a wide range of speaker configurations, including low-impedance loads (2Ω, 4Ω, and 8Ω) as well as high-impedance distributed audio systems using 70V and 140V outputs. This flexibility allows system designers to deploy a single amplifier platform across multiple installation types without additional external conversion equipment.

Built-in DSP processing provides essential audio control features such as crossover networks, equalization filtering, delay adjustment, and output limiting for optimized system performance. Up to 20 user-defined presets can be stored, allowing quick configuration changes for different installation scenarios or zones.

A switch-mode universal power supply ensures efficient and stable operation across varying electrical environments. The front-panel LCD interface enables fast configuration, monitoring, and adjustment without requiring external software tools, making installation and setup more efficient.
