The Crown CDi DriveCore 4|300 is a powerful and efficient 4-channel commercial amplifier designed to deliver superior sound quality, reliability, and control in a wide range of installed sound applications. Engineered with Crown’s proprietary DriveCore™ technology, the CDi DriveCore series eliminates hundreds of internal components to ensure consistent performance, reduced heat generation, and exceptional energy efficiency — all while maintaining the legendary audio fidelity that Crown amplifiers are known for.
Ideal for restaurants, retail stores, corporate offices, houses of worship, schools, and other commercial installations, the CDi DriveCore 4|300 provides 300 watts per channel and supports direct-drive 70V and 100V speaker loads without the need for external transformers. This allows integrators to streamline installations and minimize system complexity.
The amplifier includes a built-in DSP (Digital Signal Processor) that offers flexible configuration options such as input routing, crossover management, delay settings, parametric EQ (8-band input and output), and Crown’s LevelMAX™ limiter for optimal system protection. Through HARMAN’s HiQnet Audio Architect software, users can monitor, configure, and control the amplifier over a standard TCP/IQ network, making setup and ongoing management simple and efficient.
A front-panel LCD interface provides quick access to essential controls, while the GPIO/AUX port allows for external triggers, preset recalls, and system monitoring. Each CDi DriveCore amplifier also comes preloaded with JBL speaker tunings, enabling faster, more accurate installations and optimized performance for a variety of JBL loudspeakers.
With its combination of high-performance audio, intelligent control, and rugged reliability, the Crown CDi DriveCore 4|300 amplifier represents the perfect balance of power, precision, and value for any small to medium-sized installed sound system.
