Crown CDi4x300 CDi DriveCore 4|300 Power Amplifier

Four-Channel Installation Amplifier for Commercial Audio Systems

The Crown CDi 4x300 is a four-channel power amplifier designed for permanent sound installations that require dependable output, precise control, and long-term stability. Delivering 300 watts per channel, this amplifier is built for environments such as theaters, houses of worship, conference centers, and hospitality venues where consistent sound quality and system reliability are essential. Its installation-focused design makes it a practical solution for distributed and zoned audio systems.

DriveCore Technology for Efficient and Reliable Performance

At the core of the CDi 4x300 is Crown’s DriveCore technology, which integrates hundreds of discrete amplifier components into a single, highly efficient circuit. This streamlined design improves reliability while reducing power consumption and heat generation. The result is clean, accurate audio reproduction with reduced component variability, making the amplifier well suited for continuous operation in demanding commercial environments.

Integrated DSP for System Tuning and Control

The built-in digital signal processing allows installers and system designers to shape and manage audio directly within the amplifier. Input and output EQ, crossover filters, delays, and output limiting provide the tools needed to tailor sound for specific loudspeakers and room acoustics. High-resolution processing ensures precise control, helping maintain clarity and consistency across complex multi-speaker installations.

Direct 70V and 100V Speaker Line Support

The CDi 4x300 is capable of driving 70V and 100V constant-voltage speaker systems directly, eliminating the need for external transformers. Each channel can be configured independently for high-impedance or low-impedance operation, allowing a single amplifier to support a wide variety of speaker layouts. This flexibility simplifies system design and reduces overall installation costs.

Network Monitoring and Remote System Management

Ethernet connectivity allows the amplifier to be configured and monitored over a standard network using compatible control software. This makes it easy to adjust settings, monitor system status, and manage multiple amplifiers from a central location. Remote control capabilities are especially valuable in large facilities where equipment racks may be distributed across multiple rooms or floors.

Front-Panel Interface Designed for On-Site Configuration

A clear front-panel display and intuitive controls provide direct access to amplifier configuration, monitoring, and preset recall without requiring a computer. Programmable control ports support integration with external control systems for power management, fault monitoring, and preset selection. This combination of local and remote control options ensures smooth operation throughout the life of the installation.
