Crown CDi4x300 – 4-Channel 300W CDi DriveCore Power Amplifier

Product Overview

The Crown CDi4x300 is a 4-channel, 300W per channel DriveCore power amplifier purpose-built for installed sound applications. Engineered to support 70V and 100V distributed audio systems, it delivers reliable, high-efficiency amplification for commercial and institutional environments. Integrated DSP provides onboard signal processing, and HiQnet networking enables seamless system control and monitoring. Whether deployed in a conference facility, house of worship, or multi-zone retail environment, the CDi4x300 offers the performance and connectivity that professional installers demand.

Product Description

The Crown CDi4x300 leverages Harman's proven DriveCore technology to deliver 300 watts per channel across four independently addressable output channels. Its integrated digital signal processor (DSP) provides parametric EQ, delay, crossover, and limiting functions, reducing the need for external signal processing hardware. The amplifier's 70V/100V transformer output capability makes it ideal for distributed audio systems that require long cable runs without significant signal degradation. HiQnet protocol support allows the CDi4x300 to be integrated into comprehensive Harman audio networks, enabling remote monitoring, configuration, and control via software. The front panel LCD display and intuitive controls simplify setup and on-site diagnostics. Built in a robust 2U rack-mount chassis, the CDi4x300 is designed for standard 19-inch equipment racks. Its high-efficiency Class D amplification minimizes heat generation and reduces operating costs. Energy Star compliance and advanced power management further support sustainable installation practices. Universal AC input accommodates worldwide voltage requirements, and the included IEC power cable makes installation straightforward. Crown's industry-leading reliability and support network ensure long-term performance in mission-critical installations.
